Ondulin pros, cons and characteristics of roofing. Why reuse of ondulin is not recommended Sealing small cracks and old holes

So, in order, the information is confirmed by the test reports of the leading manufacturers of polystyrene concrete, I wrote a conclusion for myself at the end of the commentary. MOISTURE RESISTANCE and HYGROSCOPICITY This is the most important property of any building material, especially in areas with high humidity. The higher the moisture resistance of the material, the more durable, stable and warmer it is. Polystyrene concrete absorbs no more than 6% of moisture from the atmosphere, it can be in the open air for almost unlimited time. STRENGTH Due to the super-strong cement-polystyrene matrix, polystyrene concrete has unique strength characteristics. This material is so durable that a fall from a height of a five-story building will not cause significant damage to the block. FIRE RESISTANCE Polystyrene concrete does not burn, it is able to withstand the enormous temperatures caused by fire, due to its unique thermal conductivity coefficient, it does not allow heat to penetrate deep into the wall. Flammability class NG. Fire resistance class EI180. DURABILITY The service life of a house made of polystyrene concrete is at least 100 years. Over the years, the strength of polystyrene concrete only increases. FROST RESISTANCE Tests for frost resistance and the amplitude of temperature fluctuations from + 75°С to - 30°С were carried out on 150 freeze-thaw cycles without loss of integrity and heat-insulating ability. THERMAL INSULATION It has long been recognized that polystyrene (styrofoam) is the best heat insulator in the world, it is even warmer than wood! A house made of polystyrene concrete does not require insulation: it is cool in summer and warm in winter. NOISE INSULATION Polystyrene concrete provides the best noise absorption rate, 18-20 cm dampens sound from 70 decibels. Consequently, in a house made of polystyrene concrete, there is special comfort: noise from the street and inside from neighboring rooms and bathrooms does not disturb. ECONOMY The cost per square meter of a finished wall is cheaper than other materials. Due to the high level of heat retention, walls made of polystyrene concrete can be built 25% thinner than from alternative materials (aerated concrete and foam concrete) and 4 times thinner than brick. Savings on wall thickness lead to overall savings in the construction of the box (foundation, roof and walls) up to 50%. At the same time, the quality of the house will be even higher, and the house itself will be warmer. SEISMIC RESISTANCE Seismic resistance 9-12 points. Polystyrene concrete has not only compressive strength, but also the highest tensile and bending strength. Therefore, polystyrene concrete is considered the most reliable and earthquake-resistant material. LIGHTNESS A large-sized block 200x300x600 mm does not exceed a weight of 17 kg, which facilitates the work of a bricklayer and reduces the time for laying walls: it replaces 20 bricks in volume, and almost three times lighter in weight. ANTISEPTICITY The additive used in the manufacture of polystyrene concrete does not allow insects, rodents to start up in the walls, prevents the formation of mold and fungus that have a negative impact on health. VAPOR PERMEABILITY Polystyrene concrete walls “breathe” similarly to wood walls, and there is no danger of condensation and waterlogging for them. This provides a comfortable environment in houses made of polystyrene concrete. PLASTICITY Plasticity is the only material made of cellular concrete that makes it possible to produce window and door lintels, its bending strength is 50-60% of the compressive strength, for concrete this parameter is 9-11%. CRACK RESISTANCE Polystyrene concrete, due to its elasticity, is incredibly resistant to cracking. And this guarantees a long period of preservation of interior decoration and durability of the whole house. MANUFACTURING High speed of erection of wall structures due to the lightness and convenient geometry of the blocks. Easily sawn and chiseled, the ability to give the building material any geometric shape. ENVIRONMENTAL The International Building Code (IRC) classifies polystyrene as one of the most energy efficient and environmentally friendly insulation materials. Thus, polystyrene concrete has a lot of undeniable advantages over materials such as expanded clay concrete, autoclaved and non-autoclaved aerated concrete, foam concrete, wood concrete, etc. The disadvantages of polystyrene concrete appear only if its brand is chosen incorrectly and the masonry technology and preparation for interior decoration are violated. It can be said with absolute certainty that there is not a single significant advantage for materials such as aerated concrete and foam concrete over polystyrene concrete. At the same time, polystyrene concrete significantly surpasses them in key characteristics.

Ondulin is referred to as roofing materials, sometimes it is called euroslate. It is currently widely popular in the Russian markets. Like many materials, it has a number of advantages and some disadvantages. Reviews about ondulin people are very contradictory. Consider what disadvantages Ondulin actually has, and where bad and negative reviews come from. To begin with, let's look at the methods of obtaining it, in the composition and properties of this common roofing material.

How is ondulin made?

Ondulin is obtained from organic, cellulose fibers, by pressing these fibers at a high temperature of over 120 degrees. Then corrugation is performed in order to increase the rigidity of the structure. The resulting sheets are then painted and impregnated with bitumen. For example, asbestos is used in the production of classic slate, while asbestos is not used in the production of ondulin. Thus, this roofing material is safer and environmentally cleaner than slate.

Advantages of ondulin

Ondulin manufacturers guarantee 15 years of water resistance. Abroad, you can see roofs made of ondulin, which are even more than 30 years old and are in decent condition. In Russia, ondulin is only 15 years old and so far there are no known cases of loss of its waterproofing properties. Therefore, many buyers highly appreciate the absolute moisture protection of ondulin. And it really is one of the best roof coverings and resists water. Ondulin has this excellent characteristic due to the production process, in which the processed and pressed cellulose fibers do not crack over time. For example, even under the direct rays of the sun, the sheets in the places of overlap are even more firmly "glued" to each other. It also enhances moisture resistance - ondulin fastening system. Its sheets are nailed to the crate at the top of the wave, this helps water drops to roll off and not penetrate under the roof at the points where the self-tapping screw is attached. Therefore, ondulin has a huge advantage, and few negative reviews can be found on this characteristic. Isolated cases may occur if an illiterate installation is made without observing technology.

Disadvantages of ondulin

The disadvantage is a small strength. For example, a snow load can lead to pavement deformation. Therefore, it is recommended to carry out roofing work using ondulin on roofs with a solid crate or with a large slope. Ondulin sheets have a rough surface, and it does not allow snow to fall off the roof on its own. In winter, sheets of material can become brittle and walking on the roof, for example, to clear snow on the roof, install an antenna, or clean out a chimney, can cause cracks, especially in severe frosts. In the summer, the sheets soften, and the sheets are subjected to deflection. This is the main limitation, when the roof is very hot, it is not recommended to walk on it and it is advisable not to carry out work on the roof.

They also say that ondulin is paper. Of course, as noted earlier, cellulose fibers are included in the composition, but cellulose is a durable material. And many paper products cannot even be torn apart. Cellulose fiber (MDF) is used to make durable furniture. Moreover, ondulin makes the cellulose sheet wavy, profiled and this increases the strength characteristics.

Again, a competent installation must be made. When installing the roof, you must strictly follow the instructions. Each sheet must be reinforced with 20 nails, this will contribute to the strength of the roof. If the installation is carried out according to the instructions and all the installation conditions are met, then the roof will not fly off in strong winds and the snow load is not terrible for it. Do not save on nails, especially since they are included with each sheet.

The step of the crate is quite large - 60 cm with a slope of more than 15 degrees, so the crate must be correct and this will allow you to distribute the load and make it uniform. If everything is done well, then ondulin can withstand a weight of up to 960 kg per square meter and it is possible to walk on it at the attachment points and perform the necessary work on the roof.

Sometimes there may be complaints about the aesthetic characteristics of the roof. For example, loss of color saturation. The roof fades quickly, in 2-3 years and dark spots may appear. This drawback is eliminated by improving the technology of painting and increasing its resistance to ultraviolet radiation. Ondulin has a small selection of colors.

Comparison of metal tiles and ondulin

There may be a comparison of ondulin with a metal tile. But here the main plan is the price. Metal tile is more reliable, but much more expensive. If we compare ondulin with metal, which has the same price, then the metal is much inferior to ondulin. Metal, almost foil, and it will not withstand any load and rust. The thickness of the metal is 0.35-0.45mm, and the ondulin is 3mm and it is much stronger.

Dignity can be found in low strength. This material is easy to cut and can be given any shape. Easy to repair and any damaged area quickly replaced.

The disadvantages of ondulin include flammability. If a fire starts from the roof, then ondulin will ignite faster than metal. Although most often a fire starts inside the house, and not from the roof. Therefore, such a characteristic as the flammability of the roof is not very important. Even such a phenomenon has been noticed that the victims of fires die not from fire, but from carbon monoxide poisoning. And if the ondulin burns out quickly, then there will be smoke coming out and there will be a lower concentration of smoke in the room.

Before choosing a roofing material, decide whether you want to save on installation, which of course is undesirable and on which building the roof, house or garage is installed, and many other factors. If ondulin will be subject to increased risks, then select materials according to operating conditions.

If ondulin has flaws - of course, like any roofing material. No materials, no flaws. If they tell you they don't exist, don't believe them. I would like to dwell on the price again, ondulin is an inexpensive material. When you buy economical material, you must assume that you are only solving a roofing problem and not forever. With a competent and high-quality installation and without huge critical loads, you will definitely be satisfied with ondulin.

Ondulin sheet - is a wavy bituminous sheet. This is quite a budget and very practical material, which is used as a roofing. Its main advantages are that it is durable and easy to install. In appearance, it can be confused with an asbestos-cement sheet, but ondulin weighs significantly less.

Ondulin is widely used as a roofing material. Sheets are produced from the most modern raw materials. The structure contains fibers of cardboard and cellulose, as well as polymeric canvases, which are impregnated with improved high quality bitumen.

The top layer of this sheet is covered with resin, which will help protect the sheet from damage of any kind and direct sunlight. Additionally, the sheet is impregnated with a special mineral pigment, which sets one or another color or shade for the slate.

Everywhere, ondulin sheets are used to restore an old roof, laying an updated roof. Sometimes builders use ondulin sheets as wall cladding for houses, protecting them from negative atmospheric phenomena. Their use is allowed for roofs with a slope of up to ninety degrees. Thus, the material can be considered universal.

Advantages and disadvantages of an ondulin sheet

Ondulin sheet is a material that is used to cover roofs. Due to its wavy shape, it resembles slate. But that's where their similarity ends. Bitumen has a significant superiority over slate. What exactly is discussed below:

• Reliable water isolation- the house will be completely protected from rain, since the waterproofing qualities of this material are very high;
• External attractiveness- a roof made of bitumen sheets looks just great and leaves the most positive impressions;
• A light weight- one sheet weighs a little more than six kilograms, so there is little pressure on the foundation;
• The optimal combination of the declared thicknesses: thin, but durable - the thickness of the sheet does not exceed three millimeters;
• Speed ​​and ease of installation– during laying there is no need to mark sheets;
• Long service life- a bitumen-coated roof can last for many years without losing its parameters during all this time.

Bitumen sheet grades

In modern conditions, bitumen sheets are offered for sale by foreign manufacturers and factories operating in the domestic market. The most popular is the Ondulin brand, and the name of bitumen sheets has long been associated with it.

Slate from this manufacturer is easy to find in hundreds of countries around the world. Of course, the material of other manufacturers is also not too far behind, but it is inferior in quality:

• Aqualine- Belgian manufacturer. Sheets are made up of twenty-one layers of cellulose fibers, which are arranged perpendicularly. This gives the sheets a sufficient level of rigidity, but does not prevent them from being sufficiently flexible. They are mainly popular for laying roofs with complex geometries.
• Bioline– this company from Ukraine is quite young. In the production of sheets, German-made light-resistant dyes are used, therefore, even after many years, they do not lose their rich and bright color.
• Bituvel– the sheets of this German company are ideal for roofing, and are also well suited for wall decoration. They are guaranteed for up to fifteen years. This explains their worldwide popularity.
• Gutta is a Swiss company. Its sheets have a high level of chemical and UV resistance;

How to choose a bituminous sheet

What are the main characteristics should be inherent in the roofing material? Mainly:

• Long-term operation;
• Ease of installation;
• Reliability;
• Preservation of the primary color;
• Water resistant.

In addition, external characteristics are not the last parameter. Therefore, when choosing a material for a roof, they must also look at the appearance of the sheets.

Varieties of corrugated bitumen sheets

The most popular and high quality sheets produced by Ondulin. There are several varieties of ondulin, each of which will be discussed in more detail.

Ondulin Smart

These are corrugated sheets that are used in any field of construction. Ondulin sheets are endowed with a "smart" system, which provides complete isolation from water. Ondulin Smart have a specialized lock that does not allow moisture to seep into the overlap points. The end overlap is reduced to twelve centimeters. The cost per square meter - from 242 rubles.

Ondulin Smart sheets are laid in a short period of time and does not require any special skills. On each of the sheets, points are marked where nails need to be hammered. Therefore, the use of specialized tools is also not necessary.

Equipping the roof with Ondulin Smart sheets, you save your own time. In the process, there are no problems with the placement of sheets. And you don't need to do any markings.

These sheets have eight bends, not a dozen. Ondulin DIY sheets are distinguished by practicality, excellent resistance to loads, and due to this - a long service life. This Ondulin is the narrowest.

Its weight is reduced to five kilograms. Wavy sheets are an order of magnitude narrower, therefore, in which case, they can be safely transported in a car. These sheets are easy to install, therefore they do not even require outside help in work. The abbreviation DIY sounds completely in English as: Do It Yourself, and in translation means - a call to do the work yourself.

The cost of an Ondulin DIY sheet is 250 rubles. per square meter. They are ideal for renovating an outdated roof or laying a completely new roof due to their flexibility, strength and water resistance.

Tiling Ondulin

This tile looks quite natural. Its production is carried out in accordance with established standards. The cost of one sheet of Ondulin is from 264 rubles. per square meter. That allows for a very modest budget to provide yourself with a beautiful high-quality coating and protection from the weather.

Ondulin tiles are definitely beneficial. The corrugated sheets are divided into "scales" of tiles with the help of special shadow stripes. They create the visual effect of natural tiles, but are much cheaper.

Also, the advantage of Ondulin tiles is color fastness, sound insulation during rain, corrosion resistance, and the presence of a warranty period. And yes, installation is pretty easy.

You can also buy Ondulin brand products in a special online store. Be wary of materials on the construction market. Beware of falsification, require a certificate from the manufacturer.

Real ondulin is rough to the touch, does not leave traces of dye on the hands, and the weight of the sheet does not exceed 6 kilograms.

Features of installing bitumen sheets

You can accurately determine the number of sheets if you know the following parameters:

• The length of absolutely all junctions to vertical surfaces;
• The area of ​​the roof itself;
• Tilt angle;
• The number of penetrations for the chimney and ventilation;

If you do not want to overspending building materials, a rigorous calculation is required. It is made by experienced professionals. They are able to determine the required number of component parts with maximum accuracy.

Installation of corrugated sheets:

Detailed installation and fastening instructions for Ondulin - roofing fibrous sheets are in the section. We briefly summarize the main points.

• The process must begin with the preparation of the basis for laying the roofing material.

• The roof lathing must be solid, unless the angle of inclination exceeds the mark of ten degrees.

• Why use an unedged board, always with a previously removed bark and processed edges.

• A solid grate must certainly be dry and even. To make the isolation from water more reliable, a lining must be laid under the ondulin sheets. For example, it can be stekloizol. It is fixed with a construction stapler.

• If the slope of the roof is large, the crate can be arranged with a large step. To make it, bars with a section of 40 by 50 or 50 by 50 millimeters are suitable.

• Marking on such sheets is most conveniently applied with markers or colored highlighters. For cutting, a hacksaw or a circular saw is suitable. Pre-lubrication of the blade will free you from problems with tool jamming during cutting.

• The installation of ondulin sheets begins taking into account the main direction of the wind. The task is to overlap the sheets, observing a slight shift of the next row. Then the junction of four sheets will not be concentrated at a single point.

Video instruction tips for installation work, required to view:

How to fix corrugated bitumen sheets:

• If three sheets are joined in a pair of rows, then they are fixed with nails with polypropylene caps;
• The installed sheets must first be fixed on both sides, and then the remaining nails should be hammered;
• The consumption of nails for each of the sheets is twenty pieces. The width of the cornice usually does not exceed seven to eight centimeters. It all depends on the thickness of the sheet and the advice of the manufacturer.

These basic, quite simple rules will help you install the roof yourself.

If you are interested in Ondulin sheets to last for a really long time, without creating problems with sudden breakdowns, we recommend that you purchase material exclusively from official representatives. By the way, they will assist with the calculation of the required number of sheets and select all the necessary equipment.

And at the end

Ondulin corrugated sheet is an excellent material that combines the demanded attractiveness, reliability and durability. If you're looking for quality roofing, these are the best for you!

Ondulin corrugated sheets are so easy to install that it is quite possible to do the installation on your own, without resorting to the help of specialists. In addition, they have a relatively small weight, and also have special marks so that it is clear where to hammer nails. It's also easy to match the seams.

All types of Ondulin sheets are distinguished by external beauty and originality. Thanks to them, your house will immediately catch the eye, in comparison with neighboring buildings.

Disadvantages of Ondulin

Like any product, ondulin, in addition to the obvious advantages, has its drawbacks. Unfortunately, there are no ideal things in the world. We list the main disadvantages:

1. Material burns. However, there is no danger of spontaneous combustion.

2. Beautiful color will fade over time. After 20 years, the color will fade. At the same time, the waterproofing properties of ondulin will remain at the same level. What's more, you can paint the roof any color with water-based acrylic paint.

3. Weak wear resistance. There was a judgment that ondulin does not have high strength. This is partly true, but by observing the ondulin laying technology, you will protect yourself from such problems. In fact, the technology allows you to load 1 m2 of roofing material up to 960 kg.

4. Rough surface does not allow snow to roll. The debatable question is which is better, the constant need to remove fallen snow or calmly wait for spring when it melts. Leave it to your discretion and look forward to your feedback in the comments.

Onduvilla roof lasts a long time. Unfortunately, not all building materials have the same durability, and it is impossible to postpone the replacement of an unusable insulation or the repair of a sagging truss system. In such cases, it is necessary to dismantle the serviceable roofing.

With a good owner, everything goes into business. Many building materials are given a second life, and Onduvilla tiles are no exception. It can be laid on the roof of a garden gazebo, covered a garage, carport, or laid on a new attic.

Dismantling the onduvilla

Dismantling an onduvilla is a painstaking task. Thanks to the ring knurling, the roofing nails are firmly held by the batten, and they must be removed so that the tile sheets remain intact. There are several ways to dismantle:

The head of the nail is bitten off with powerful end cutters. After removing the sheet, the nail rod is driven into the crate;

The head of the nail is cut off with a grinder, the incision is made above the corrugation on one or both sides. After removing the sheet, the rod is recessed into the crate;

A carpenter's hammer with a nail puller is used to remove the nail. As a support, a board about 1 m long and 9 cm wide is used (the distance between the onduvilla corrugations). The thickness of the board should correspond to the height of the corrugation - 4 cm.

The dismantling of the roofing is carried out early in the morning or in cool weather. At low temperatures, the material is more rigid and less likely to be damaged.

Installation of a used onduvilla

2. Laying onduvilla is carried out according to the instructions:

The length of the eaves overhang is set to 5 cm. If the roof is mounted on an old crate, the eaves overhang should be reduced by 1.5-2 cm. In this case, the recessed nail rods will not interfere and the fastening will be strong;

The bituminous tile keeps within "razrazbezhku". With this method of installation, the joints of the sheets of the upper row fall on the middle of the sheets of the lower row;

Laying is carried out from the leeward side, from the bottom up;

To make the roof look voluminous, onduvilla is laid with the dark side up;

Ondulin is used to fasten the onduvilla.

Onduvilla renovation

In the process of dismantling, cracks, chips and other damage may appear on bituminous tiles. In most cases, a simple repair allows you to completely restore the onduvilla.

1. To repair a crack, you must:

Drill a hole with a diameter of 2-3 mm at its end and thereby prevent further growth;

Seal the crack with Onduband Pro mounting tape of the appropriate color.

2. Onduvilla waste patches are used to repair chips and large holes. Patches are installed on bituminous sealant and fastened with Ondulin nails.
