Ondulin characteristics properties and fastening devices. Ondulin roof - step-by-step installation instructions

Euroslate, also known as ondulin, is an inexpensive type of roofing that looks slightly reminiscent of its gray historical predecessor. This type of roofing, which is relatively new to us, differs from ordinary slate in its lightness and color variety.

Corrugated bitumen sheets are attractive due to their decorative qualities and do not cause difficulties in cutting and fastening. In addition, ondulin tiles are extremely easy to install, especially if an independent roofer knows all the technological nuances.

In the production of ondulin, organic and inorganic fibers are used, which together form a homogeneous mixture. The fibers are tightly pressed and impregnated with bitumen, resulting in a material with equal physical and mechanical properties at all points.

Multi-layer material ensures resistance to a variety of mechanical stress. The wavy relief enhances the effect, forming peculiar stiffening ribs that resist the pressure of snow deposits, hail and direct rain jets.

WITH outside corrugated sheets are covered with a polymer protective and decorative shell, which gives the coating color and protects against the aggression of UV rays. Real ondulin does not fade for a long time after installation. Counterfeits are not painted with compounds containing light-resistant components, so they fade after a couple of years.

The surface of Euroslate is given a special texture that facilitates the independent removal of precipitation from the roof covered with it. Snow deposits, dust and atmospheric dirt do not linger on a bitumen roof with a slight roughness and polymer protection.

Ondulin is used both in new construction and in restoring the technical characteristics of old roofs. IN repair work It is permissible to lay directly on old slate or on a lathing installed on top of a worn-out covering. The material is used mainly as a roof for low-rise buildings with roofs with a slope of 10º or more.

The material is supplied by different manufacturers. In general, the technical data of factory-made products differs little from competing offerings. The main feature of real Euro slate is the number of waves in the sheet, which should be exactly 10, and uniformity in the cut.

Assessing advantages and disadvantages

No matter how hard roofing developers try, no one has yet achieved perfection. Including engineers who worked on the invention and modernization of ondulin. Like any other roof, Euro slate is endowed with undeniable advantages, but still not without some disadvantages.

The buyer’s task is to soberly compare the pros and cons of ondulin tiles in order to ultimately resolve the issue of the suitability of the material for the roof of his favorite country property.

First, let's list the advantages of Euroslate:

• Minimal moisture absorption. Bitumen impregnation, enriched with polymers, completely fills all the pores of the pressed material, depriving water of the slightest opportunity to penetrate into its thickness and under it, into the under-roof space.
• High noise insulation. Made from multiple fibers, the material perfectly prevents the passage of sound vibrations from outside and inside the building. This quality is extremely attractive to fans of furnished attics.
• Resistance to biological and chemical aggression. Euroslate roofing will not be damaged by acid rain, industrial smoke, and will not be corroded by mold and putrefactive bacteria.
• Manufacturability. Ondulin is easily cut, fastened, and, if necessary, the material is bent in the required places. A sheet of material weighs only 6 kg. One person can easily handle the installation of a roof with European slate without help.
• Versatility. Euro slate is used in roofing work, regardless of the climatic specifics of the object. It perfectly resists frequent gusty winds and resists snow drifts.

However, we note that bitumen slate is a material perfectly suitable for mid-latitudes. In hot weather, the bitumen it contains can melt and the roof can become deformed. In severe frosts, the leaves become fragile.

An important advantage is the safety of the material according to environmental criteria. During operation, it does not emit toxins that threaten the environment. Used roofing can be disposed of without any problems - just burn it.

The list of shortcomings is shorter, but you should also take a closer look at it. The disadvantages include:

• Insufficient strength. In terms of resistance, bituminous material still cannot be compared with roofing tin and clay tiles. It serves less than the indicated rivals. If the installation rules are violated, ondulin may bend in places or lose its wavy relief.
• Flammability. Corrugated bitumen sheets are impregnated with fire retardants, but these measures cannot completely eliminate the ability of the material to support an incipient fire, although ignition of Euro slate requires long-term exposure to high temperatures.
• Color instability. Bright during operation bitumen roofing still “fades.” Loss of color is typical even for original products, which will lose their brightness after 5 to 7 years. Fakes fade much faster.

The disadvantages of corrugated bitumen sheets, of course, are offset by the affordability of the price, which, by the way, explains and justifies the short operating time.

None of the manufacturers promises that a roof made of Euro slate will last more than 15 years. This is much less than 50 years of profiled steel roofing and 100 years of ceramics or natural stone.

Let us note that the service life and reliability of an ondulin roof largely depends on the competent execution of installation, the specifics of which should be familiarized with as independent craftsmen, and those who resort to the services of hired builders.

Ondulin laying technology

For flexible slate roofing, special fasteners are produced that make it possible to clearly fix corrugated sheets, corner parts, intended for the design of junctions, elements for the ridge and valley, insulating gaskets for arranging the edges of the slopes.

The main thing is that the material comes with a step-by-step installation manual from the material manufacturer, which covers all possible installation options and cases that may be encountered when performing roofing work. Those wishing to install ondulin with my own hands You should study the instructions thoroughly.

Specifics of the construction of the sheathing

Bituminous slate can hardly be classified as a hard coating, so the construction of the base under it should be taken extremely seriously. The arrangement of the sheathing under it is determined by the slope of the slopes:

• For structures with a slope of 15º and above. The sheathing is made of bars with sides of 40 or 50 mm. Laths are placed every 60 cm, the step is reduced in regions with heavy rainfall to 45 cm.
• For roofs with a slope in the range of 10 – 15º. The standard spacing for lathing fastening is considered to be 45 cm; in areas with characteristic snow deposits, the indicated distance between the lathing elements is reduced.
• For awnings over extensions and canopies with a slope of 5 – 10º. The sheathing is assembled from boards, waterproof plywood or OSB sheets. When using a board, it is laid with a gap between the elements, which can reach 5 cm.

In device continuous sheathing Above gentle slopes, it is permissible to use unedged planks, from which the wane must be removed before installation. All lumber must be treated with fire retardants before construction, because they will have to come into contact with a coating that is unsafe in terms of fire.

Let us immediately note that the amount of overlap of the corrugated sheets depends on the slope of the slopes. On flat structures up to 10º, Euro slate is laid with the next sheet overlapping the previous one from the side in two waves. The overlap of the overlying row on the lower one should be 30 cm.

Roofing on slopes higher than 10º is laid with an overlap of one wave on the side and an overlap of 20 and 17 cm at the top. It is clear that the steeper the structure, the less overlap, because on such roofs there is less lingering precipitation.

When installing timber sheathing, eaves overhangs, valleys and areas near the ridge girder are made continuous by laying boards, since in these areas the roof is most likely to sag under the influence of accumulated snow.

The sheathing is usually made with an overhang slightly larger than required by the project. Eaves overhangs are created by extending cuttings of boards onto rafters – fillets. By going beyond truss structure laths along the lines of pediments and fillies, in fact, form the shape and size of the slopes.

Upon completion of the construction of the base, the excess is cut off, having previously measured the diagonals and adjusted the shape of the slopes if necessary. Therefore, laths and fillies are initially taken with some reserve.

Sheet cutting planning

Project with bitumen slate layout for complex structures with many constituent elements it is customary to do using computer programs. It is better to order such work from a design office, having first called a surveyor to obtain truly accurate data.

Laying out the material for a simple roof can be done independently without any problems. To do this, you will need a piece of graph paper and tracing paper: on the first one you will need to draw the elements of the ondulin in a suitable scale, on the second - the outline of the slope with structural details and the sheathing made.

Do not forget that it is necessary to draw sheets on graph paper taking into account overlaps - overlapping sheets of material along the side and bottom lines. When calculating overlaps, we take into account the slope of the slopes.

Please note that according to the rules for laying flexible slate, the rows should be arranged according to the “fish scale” principle, i.e. with mixing of the side seams of the overlying rows relative to the seams of the underlying rows.

Let's put tracing paper with the slope lines marked on it on graph paper with the layout of sheets of Euro slate and move it until we find best option with the largest number of uncut sheets. We make sure that the top line of the sheets is located exactly above the lath.

When designing cutting for arrangement hip structures it is necessary to ensure that the top corner elements slate fell on the lath. If the ideal layout does not work out, you will have to lay additional bars in problem areas and trim them to the shape of the slopes in place.

In order to ensure displacement of longitudinal seams in simple rectangular slopes, it is recommended to start each even (or odd) row with sheets cut in half. The displacement is required to prevent water from penetrating under the roof at the junction of the slate sheets, and also to exclude points formed by four layers of covering.

Rows with sheets cut along the transverse line can be located both at the eaves edge and near the ridge. It should be remembered and taken into account that a Euroslate roof must have a free overhang, the size of which is indicated by the manufacturer. It should not be exceeded so that the edge of the covering does not bend under the weight of the snow.

European slate is cut along the lines of depressions in the wavy relief. They cut with a regular hacksaw with a blade designed for wood, which must first be lubricated with oil. Instead of a hacksaw, a circular saw or jigsaw is suitable. You should not cut with a grinder - its discs will melt the bitumen impregnation.

The process of laying wavy coating

Euro slate is laid over a waterproofing carpet. The material for waterproofing is selected depending on the type of structure.

For cold roofs, a vapor-permeable membrane is purchased that will freely allow household fumes that form inside to pass through, but will not allow atmospheric water to penetrate inside.

When installing insulated roof structures with ondulin roofing, a vapor-tight protection is placed under the insulation, and a vapor-permeable material is placed above the thermal insulation.

Bitumen slate is laid in the direction opposite to the prevailing winds. Since each subsequent element overlaps the underlying previous fox with a wave or two, as a result of laying in the indicated direction, air flows will not spoil the roof, trying to tear off the ondulin, but will become like “ironing the wool.”

Markings are made on the prepared base using coated string and a colored pencil. First, mark two points of the outer sheets on both sides of the structure, then the resulting points are connected with a line, after:

• If there is no need to adjust the slopes, then the following lines are precisely drawn from the resulting line;
• If the geometry of the slopes is not entirely accurate, then it is better to slightly change the marked lines before laying, slightly reducing or increasing the overlap where required.

Even before starting installation, you need to mark the edge of the free overhang. To do this, hammer a nail into the end of the two outer rafters so that their heads mark the extreme points of the free overhang. Stretch twine is attached to the nails. On long slopes, it is better to hammer in more than two nails.

The starting sheet is laid according to the markings. The laid element is immediately fixed with nails. Note that it will serve as a guide for continuing the row and laying the next sheet on top, so it must be aligned with extreme precision.

The use of wind strips laid on the edge of the eaves eliminates the need to scrupulously level the starting sheet, but even in this case, you still need to constantly check the directions of laying the piece roofing. True, some deviations in the geometric data of the design will be masked by the corners.

Nuances and order of fastening

Fasteners produced specifically for a specific collection of ondulin are installed strictly perpendicular to the sheathing. Nails are driven exclusively through the ridges of corrugated sheets with mandatory penetration into the wooden base.

The flexible slate is fixed in a clear sequence, which is not recommended to be violated:

• First, fasteners are placed along the edges of the sheet.
• Afterwards the middle of the element is fixed.
• Then the remaining attachment points are installed.

It is strictly forbidden to knock down the sequence, otherwise the flexible sheets may become warped. The spatial geometry of the wavy element will be disrupted. It is forbidden to deepen the nails and tighten the fasteners too much, because the ondulin will flatten.

If you follow the specified sequence, then an accidentally deeply buried nail will have virtually no effect on the geometric shape of the wavy coating.

In one or two waves that go under the side overlap, fasteners are not installed, because these lines will be fixed along with the subsequent sheet. By analogy and for the same reason, fixation is not made along the top line of the sheet.

If you plan to install a wind angle along the gable overhang, the fasteners are not placed in the outermost wave of the starting sheet; it will be secured later during the fixation of this shaped element. The shaped part is attached to each batten of the sheathing through the highest point of the wave and the corner flange.

If you refuse to use the wind angle, fixation is carried out according to the same scheme, but without the shaped part. Nails are placed in each lath on the side, and nailed to the bottom beam through each ridge at the lowest point. In the middle, the covering is attached in the same way - through the top of the wave to the sheathing.

According to the calculations of experienced roofers, 22 nails are required to fix one corrugated bitumen sheet if the sheathing bars were installed in increments of 45 cm. It is advisable to carefully consider its location before installing the attachment point.

An incorrectly installed nail, of course, can be removed with a nail puller, but the hole from it will significantly reduce the airtightness of the roof. To create support during “pulling out,” you need to stock up on a piece of pipe whose diameter is equal to the size of the coating ridge.

The installation algorithm described above will need to be followed until the entire slope is covered with ondulin. It is clear that the installation procedure itself is not much different from the installation of conventional slate. The main thing is to perform the actions clearly and accurately.

Design of overhangs, cornices, valleys

When arranging a gable overhang, it is not necessary to use a ready-made corner. You can simply bend flexible slate onto the wind board. When choosing this method, you need to take into account that its implementation is possible only at above-zero temperatures, when the Euro slate becomes soft. In the absence of good weather, you can use a hair dryer.

To form junctions with walls and brick-made ventilation shafts, skylights, and chimney pipes for ondulin, shaped elements are produced. They are attached through the ridges of the flexible sheet to the sheathing. Before installing the junctions, they are glued with waterproofing tape, which is also produced for the construction of bitumen slate roofs.

Concave and convex corners of the roof are equipped with corner shaped parts in which both shelves are equal in width. One of the shelves is placed under the covering, the second is released on top of it so that the path to the under-roof space for rainwater flowing down the slopes is completely blocked.

Ventilation under the roof is provided by breathable gaskets that do not interfere with flow air flow, but protecting from dust, dirt, branches, insects, birds. They guarantee complete removal of condensate and atmospheric moisture if it penetrates outside.

Ridge parts are installed upon completion of the roofing of adjacent slopes. On hip roofs, the hip ribs are first installed, then the ridge ridge element is installed.

Installing ondulin will not cause any difficulties for inexperienced home craftsmen. Especially if they are familiar with all the intricacies of laying and fastening the material. A beautifully and competently equipped roof will serve the owners longer than the period promised by the manufacturer if all technological rules are followed.

Many people far from construction wonder what ondulin is. Since this new word is constantly being heard, it attracts a lot of attention from those interested in modern technologies specialists and curious homeowners alike.

In fact, the term "ondulin" means modern look roofing material based on cellulose and bitumen, the coating of which reliably protects the roof from precipitation and adverse weather conditions long years. In this article we will tell you what ondulin is made of, how much it costs, what types of this material are produced, and where they are used.

Ondulin is a modern, technologically advanced roofing material that is used to create a stable, moisture-resistant coating. It is a product and protected trademark of the French company Onduline, which began its production more than 70 years ago.

On Russian market This roof covering, which is made on the basis of cellulose impregnated with purified bitumen, came only 10-15 years ago, after which it earned the trust of professional roofers and developers. Currently, the following types of this material are distinguished:

• Ondulin

The classic ondulin coating is a rectangular sheet with a wavy profile, the size of which is 200x950 cm. It has high moisture-proof properties, light weight and guaranteed period operation 15 years.

Installation of classic ondulin is carried out in the same way as laying traditional slate. The wave height of this material is 36 mm, and the sheet thickness is 3 mm. The cost of 1 m2 of such a roof will be 300-350 rubles.

A product of collaboration between the French company Onduline and Italian designers. This roofing material is a symbiosis. Onduvilla is cut corrugated strips, the wave height of which is 36 mm, width 40 cm, length 104-106 cm.

Onduvilla is laid in tiers with a slight overlap, its waves imitate ceramic tiles in Mediterranean style. Such a covering with an area of ​​1 m2 weighs only 4 kg. Onduvilla costs from 410 rubles for 1 square meter.

Onduvilla is a mixture of tiles and ondulin.

By adding natural pigments, the material is painted in the required colors. Standard colors include black, brown, green and red.

Ondulin coating tends to fade under the influence of ultraviolet rays, and the destruction of the pigment occurs unevenly. To update the color of the roof, a primer is applied to it and then painted.

Interesting! Initially, the roofing material ondulin was developed as a means for repairing metal or tile roofs, which does not require dismantling the structure. Lightness and excellent moisture-proof properties made it possible to lay this material over the old roofing pie. During its operation, it began to be used to cover roofs independently.

Production process

Light weight, moisture-proof properties and simplicity are explained by the characteristics of the substances from which it consists. It, like onduvilla, is produced from environmentally friendly, healthy components, which cannot be said about.

The composition includes waste from the pulp industry, petroleum bitumen, polymer resins, natural pigments, and modifiers. During the production process, ondulin coating and onduvilla go through 5 stages:

1. The first stage of manufacturing this roofing material is called wet, since during it waste paper, cleared of impurities or debris, is mixed with water, obtaining a wet paper mass called pulp.
2. The next phase of production is called drying. During this process, the prepared pulp is fed to a conveyor, where it is given a wavy shape and then dried.
3. Completely dried sheets are cut according to standard material sizes, and then sent to the impregnation workshop.
4. Sheets of roofing material are impregnated with petroleum bitumen on both sides under the influence of high temperature and pressure.
5. Onduvillas are stacked on pallets and then wrapped in shrink film to prevent mechanical and weather damage to the material during transportation or storage.

The conveyor for the production of this roofing material produces one finished sheet in 4 seconds. From the moment the pulp is supplied to the conveyor to packaging, ondulin is produced within 45 minutes. During the manufacturing process, all components included in the coating are checked for compliance with safety requirements. Thanks to strict quality control, it is considered one of the most environmentally friendly materials.

Characteristics

Ondulin is used for repairing roofs, laying new coverings, as a lining for ceramic tiles or to create fences and waterproof screens. A coating made of this material has a guaranteed service life of 15 years, however, according to reviews from professional roofers, it has a trouble-free service life of at least 30-50 years.

Light weight, affordable cost, moisture-repellent properties and resistance to biological factors of destruction make ondulin indispensable in private housing construction. The technical characteristics of this material meet high standards:

• The destructive load of roofs covered with ondulin is at least 960 kgf/m2, and it is not the sheet itself that is destroyed, but the sheathing or rafter frame.
• The elastic modulus of the material is 3,940-8,160 kgf/m2, due to which the sheet is highly flexible.
• The material can withstand temperatures up to 110 degrees without deforming or losing elasticity or rigidity.
• The noise reduction level of ondulin is 40 dB, which allows you to accept this material without additional sound insulation.
• The thermal conductivity coefficient of ondulin is 0.19 kcal/mchoC. The thermal conductivity of this material is significantly lower than that of the roof, so the roof does not heat up as much when exposed to the sun.
• This roofing material can withstand at least 25 freezing and thawing cycles without loss of mechanical strength and moisture resistance, which explains the long service life of roofs coated with ondulin.

Note! Ondulin and onduvilla are flammable roofing materials, since the components included in the composition do not have fire protection. To increase fire safety, manufacturers do not recommend using such a coating for roofs through which chimneys are routed. solid fuel stoves or fireplaces. To prevent fire, it is necessary to equip the pipe passage with a fire-resistant box, and also install a spark arrester made of sheet metal.

Video instruction

Roofing material ondulin is usually considered as an aesthetically attractive and easy-to-install analogue of traditional slate. A bright roof made of ondulin looks impressive and has a number of advantages. However, the material is not without some disadvantages. Its properties will be discussed in detail below.

Features of the material

Ondulin first appeared on the construction market in the 40s of the last century. Invented in France, the roofing material has been improved over time due to technological developments. In Russia, ondulin, specifications which allow it to compete with a wide range of coatings, enjoys well-deserved popularity.

The advantages of the coating are due to the use of high-quality components. Used for the manufacture of corrugated sheets:

• cellulose fibers (base);
• bitumen purified using special technology;
• polymer resin impregnation;
• mineral filler;
• harmless natural pigments based on mineral substances.

Impregnation of the cellulose base of ondulin is carried out under high pressure, which provides the necessary strength characteristics finished product. The use of natural substances guarantees the environmental purity of the material. Mineral dyes make it possible to produce sheets of various colors.

Basic characteristics

Ondulin is produced in sheets measuring 200×95 cm, 3 mm thick. The height of the corrugation is 36 mm. Considering that when installing the covering, corrugated sheets are laid overlapping, the useful area of ​​ondulin is 1.6 m. This should be taken into account when calculating the amount of material required for arranging the roof.

The weight of a sheet of ondulin is only 6 kg, while one sheet of slate weighs more than 4 times more - 26 kg. Light weight is the main advantage of bitumen roofing material. Thanks to this property, ondulin is much easier to install, since you can lift the material onto the roof alone.

Considering how much ondulin weighs, we can say that its delivery will cost much less than transporting slate. If necessary, ondulin can be transported by passenger vehicles. In addition, loading and unloading sheets requires significantly less effort and time.

Since the weight of ondulin allows the installation of light coverings that do not place a high load on the structure of the structure, when installing a roof made of ondulin, you can use a lightweight rafter system.

Basic properties of the material: pros and cons

The list of technical characteristics of ondulin primarily includes such parameters as resistance to temperature influences, durability, fire safety, and environmental friendliness.

Durability. Operational life Ondulin, subject to proper installation, can be more than 25 years. In this case, the manufacturer provides a guarantee of 15 years of service. This characteristic does not distinguish corrugated bitumen sheets from other roofing coverings - you can choose a more durable material.

Resistance to temperature changes. This property can be attributed to the disadvantages: due to the introduction of polymer additives, ondulin is more resistant to temperatures than roofing felt, however, the sheets soften in the heat and become brittle in the cold. Improperly executed lathing can lead to damage to the roofing under snow load.

Environmental friendliness. An undoubted advantage is the environmental friendliness of the material, made from natural ingredients, confirmed by relevant certificates. Manufacturers emphasize that such a roof can be used to collect drinking water during precipitation. The disadvantages include bad smell bitumen, which can appear in very hot weather.

Fire safety. The disadvantages of ondulin include its low fire safety class, since the material contains bitumen. At temperatures above 230 degrees, ondulin is capable of self-ignition, supports combustion, and has high smoke-generating properties. It can be used on the roofs of buildings that are subject to increased fire safety requirements (educational and children's institutions, etc.), but in this case, installation is carried out using special fire-resistant cuts. They allow you to divide the coating into separate segments to localize possible fires.

The positive properties of ondulin are inherent in many roofing materials. The list of advantages can include:

• noise insulation properties;
• biological resistance (resistance to fungi, mold, insect damage);
• resistance to aggressive environments;
• UV resistance.

An undoubted advantage is the wide range of ondulin shades, thanks to which you can choose the most suitable color roofs.

Installation features

The technical characteristics of the material, namely low weight, flexibility, fragility at low temperatures, have a certain impact on the principles of roof installation. In general, fastening the covering sheets is carried out in the same way as installing corrugated slate - the installation is done overlapping, and for fastening to the sheathing, roofing nails or self-tapping screws with a rubber gasket are used, which protects the structure from moisture penetration.

Such a property as flexibility is, to a certain extent, one of the disadvantages of ondulin. With a large sheathing pitch roof structure becomes vulnerable and may not withstand high snow and wind loads. Regarding these technical characteristics, hard materials, including slate, have an advantage.

Installation of a reliable roof made of ondulin begins with the manufacture of the correct sheathing. Its surface should be absolutely flat, and the pitch should be much smaller than for hard coatings. The complexity of installing the sheathing and the need to use a number of special elements(insulating tapes, strips, aprons, etc.) leads to an increase in the total cost of manufacturing the roof - this is a minus of ondulin.

Grand total

Ondulin, the pros and cons of which are quite obvious, cannot be attributed to inexpensive materials. In the appropriate price segment, if necessary, you can select a roofing material that is not inferior in properties to ondulin. However, due to its technical characteristics and wide possibilities design, it successfully competes in the construction market.

Ondulin pros and cons: technical characteristics, usable area and weight

Pros and cons of ondulin. Main technical characteristics of ondulin, its usable area and weight of one sheet

Characteristics of ondulin: pros and cons of the material

Today, few developers will not pay attention to the multi-colored elements of ondulin. The products have firmly conquered the market due to their advantages, but there are also disadvantages that you should also know. The characteristics of ondulin are often discussed; it is not for nothing that the material is called Euroslate, paying tribute to aesthetics and practicality. Let's look at the advantages, disadvantages and types of coating in more detail.

Technological features of ondulin production

Roofing was invented more than a century ago and today the principles of production have been preserved. In the manufacture of products, cellulose fiber is used, which goes through the processes of heating, pressing and corrugating at a temperature of +120 C. After this, the elements are coated with paint and impregnated with bitumen compounds with polymer additives.

In fact, ondulin is a type of slate, but with higher practical and quality characteristics. The production process produces an environmentally friendly safe material with high levels of water resistance and strength. When exposed to sunlight, thin cellulose fibers are welded together, guaranteeing excellent waterproofing.

Basic material characteristics

The standard sheet is produced in sizes 200-95 cm, thickness 3 mm. Wave height (corrugations) 36 mm. Taking into account the fact that when laying the sheets are placed overlapping, the useful area of ​​the roofing material is 1.6 m. To select the material and correctly calculate the required quantity, the technical characteristics of ondulin are necessary - a roofing covering that has a stable shape; calculating the required volume will not be difficult.

When thinking about what to choose: ondulin or slate, it is worth considering the mass. An ondulin sheet weighs 6 kg, a slate sheet weighs 26 kg, the low weight facilitates installation, transportation and supply of sheets to the roof.

Advice! The lightweight weight of the roofing sheet allows you to do without additional calculations load-bearing structures necessary for the installation of the roof. The material can be laid on the roof of old buildings without fear that the structure will collapse under the weight of the roofing carpet.

So, ondulin technical characteristics:

• Ignition 230-300°, fire safety class KM5 (the latest), because of this the material is not recommended for use in areas large cluster people, medical and educational institutions.
• The load that destroys the material is 0.96 t/1m2. In this case, it is not the sheet itself that is destroyed first, but the sheathing and rafter system.
• Resistance to chemicals is high. No other material tolerates alkalis, acids, or petroleum products like ondulin; the characteristics of the material are suitable for covering roofs in environmentally unfavorable areas.
• The presence of a hygienic certificate confirms high hygienic indicators.

Good water resistance and a 15-year warranty complete the main characteristics of the material.

Benefits of ondulin

When considering the pros and cons of ondulin, you should immediately turn to the characteristics of the material - almost all of them talk about positive qualities ah material. The list of advantages can be supplemented with the following properties:

1. Due to the fact that when installing the sheet, the nails are driven into the highest point of the wave, the sheets never get wet - drops of water roll down without causing damage to the coating.
2. High hygienic, water-repellent properties have been confirmed by decades of use of the roofing product.
3. Lightweight makes installation quick and easy, while the rafter system can also be made lightweight.
4. Sheets are easily and quickly cut with a regular hacksaw, and if you lubricate the cut area with oil, work will go faster.
5. The sheets are flexible enough that you can give them any shape, which means you can cover the roof of the most bizarre design, as shown in the photo.
6. The low price (from $5) is another plus; it turns out that the roofing material ondulin is much cheaper than its analogues, except slate, but does not contain harmful asbestos fiber.

A low noise threshold, biological stability, and resistance to UV rays complete the list of positive qualities of the material.

Disadvantages of roofing

But ondulin has disadvantages that are often forgotten by manufacturers who present the product as one of the best roofing coatings. Most of the negative aspects appear due to improper installation, but there are still certain disadvantages:

1. Strength. It is not high, but if the installation technology is violated, in particular, less than 20 nails are driven into the sheet, then the strength of the element will noticeably decrease. With normal lathing with a pitch of 0.6 m and a slope above 15°, the sheet can withstand up to 800 kg/m2.

Important! During periods of extreme heat, you should not walk on the coating to prevent the sheets from bending; in addition, the release of odors from bitumen impregnation is possible.

1. Fire hazard is another disadvantage that ondulin has, the properties of cellulose as an organic material do not exclude the possibility of fire.
2. Durability is always questioned, despite the 15-year warranty. It all depends on the correct installation and operating conditions of the facility. Only the best metal tile roof can withstand extreme conditions, but every developer is capable of following the installation technology to extend the service life of the material.
3. Burnout. Time and precipitation lead to changes in the color tone of the sheets. If the sheets faded quickly enough, it means that the ondulin was of poor quality: the sheets are painted before impregnation with bitumen compounds, otherwise the shade will quickly fade.
4. Resistance to biological effects depends on the light: in the dark areas of the leaf, after 2-3 years, mosses form, and the surface turns green. But the same thing happens with slate.

If installed correctly, the roofing covering will last a long time, but knowing what ondulin is and the pros and cons of the material will make it easier to decide on the choice of roofing covering.

Modern varieties of material

Manufacturers offer not very diverse types of ondulin, these include:

1. Smart is a bituminous material that has the following qualities:
   • a smart lock that complements the functions of a hydraulic barrier;
   • attachment points;
   • smaller dimensions: size 195*95 cm, thickness 3 mm, weight reduced by 5%;
   • number of combs 10.

1. DiY is a material with even smaller parameters: 5 kg with dimensions 0.2 * 0.75 and thickness 3 mm. Number of combs – 8.

Important! Reducing the overall dimensions of the sheet is a big plus; in this case, installation is carried out with a large number of overlaps, which gives the roof covering the necessary rigidity and resistance to increased loads.

Product batch is always standard sizes, which allows you to select color combinations to suit the taste of the developer. Therefore, knowing what types of ondulin products there are, there is always an option to make the roof individual and aesthetically attractive, as shown in the photo.

Product reviews

Opinions about roofing material vary; developers praise and criticize ondulin. Reviews from real owners will help you make your own judgment and give preference to one or another type of material.

1. The judgment is restrained and positive. The sheets quickly changed color, the composition is a little alarming, but affordable price and the speed of installation justify all concerns. (Maria, Moscow).
2. The roof was resurfaced 2 years ago, it looks good, there is no noise when it rains. If we take into account flammability, then there is something to argue with: the cardboard will burn out, and the metal profile will have to be cut out and removed. The snow did not cause any problems: during the thaw, it melts and rolls off in drops, rather than falling in heaps on one’s head; by the way, the summer heat had a worse effect on the neighbor’s metal sheets: the metal rattled when heated, and my roof was “silent”; there was no big smell either. I had to walk on ondulin in the heat (on the roof of the bathhouse), the sheets were dented, but recovered. Therefore, all the talk about shortcomings can only happen when choosing a low-quality product. (Oleg, Kirov 2017).
3. The roof is beautiful, but the rough material is a “bait” for the accumulation of leaves. If you take care of it and lay it out correctly, it looks very decent, and at the same time inexpensive. There were no negative phenomena in the form of smell or leaks during the 4 years that the roof was covered, but it had to be repainted - the sun was bright, the sheets were slightly faded (Olesya, Ivanovo).
4. Change and not install - that’s my opinion. Ondulin sheets are pierced by woodpeckers chasing flies, and this happens quickly. The neighbor also complains that he is tired of sealing it with sealant. (Roman, Obninsk).

Advice! The scope of application of the product, due to its high practical qualities, is wide, but strength remains not the highest indicator, so ondulin loses to all other materials and is used most often to reduce financial costs for construction.

To give preference to slate, metal profile sheets or ondulin is the owner’s choice. You just need to calculate your own finances and strength. If you can handle ondulin elements alone, then with metal or slate you will need an assistant. In addition, the speed of installation and the possibility of arranging a lightweight rafter system, which sometimes becomes a necessity in the object being built.

• The roof sheathing must be continuous, unless the angle of inclination exceeds ten degrees.

• What is it used for? unedged board, always with pre-removed bark and processed edges.

• A solid grate must be dry and level. To make the insulation from water more reliable, a lining must be placed under the ondulin sheets. For example, it could be glass insulation. It is fixed using a construction stapler.

• If the roof slope is large, the sheathing can be arranged in large increments. To make it, beams with a cross section of 40 by 50 or 50 by 50 millimeters are suitable.

• It is most convenient to apply markings on such sheets with markers or colored highlighters. A hacksaw or a circular saw. Preliminary lubrication of the blade will free you from problems with the tool jamming during cutting.
