French chic: ondulin on the roof

Imagine the classic allure of French architecture, where sophistication and elegance permeate every element. Imagine this essence now encapsulated in ondulin, a contemporary roofing material. This roofing option is a favorite of both architects and homeowners because it blends the elegance of classic French design with the usefulness of modern building materials.

The characteristic wavy profile of ondulin roofing is what makes it unique and evocative of the traditional French roofs that adorn charming rural homes and villages. This distinctive design fulfills practical needs in addition to adding aesthetic appeal. Rainwater is effectively diverted from the roof, stopping leaks and preserving the structure over time.

Ondulin is valued for its robustness and light weight in addition to its aesthetic and practical qualities. Constructed from bitumen-soaked recycled cellulose fibers and sealed with a resin coating, it provides strong weather resistance without harming the environment. Ondulin is a favored option in both urban and rural retreats because of its strength and sustainability.

In addition, ondulin roofing is reasonably easy to install, making it affordable for homeowners wishing to add a touch of French flair to their home. Because of its lightweight design, builders and renovators can save money and have more convenience because it is easier to handle and takes less time to construct.

What is Ondulin

Gastan Gomeier, a Frenchman, worked hard to create the material ondulin in 1944. It’s known as the Euro-Shifer in Russia, where it wasn’t discovered for 50 years.

As the article’s author pointed out, Ondulin is sometimes referred to as tiles. But this is incorrect. It must be a peculiar substance to be mistaken for the Ondille Bitumen-Keramic tile, which resembles a Euro-shifer but has entirely different dimensions and compositions.

The following elements are included in Ondulin’s composition:

• cellulose fibers compressed at high temperature;
• bitumen impregnation;
• resin;
• mineral pigments;
• coloring substance.

It turns out that Ondulin is free of dangerous elements (asbestos), in contrast to the slate, which he somewhat resembles. Mineral pigments and resin serve as beneficial additions. They aid the substance’s resistance to the deluge of atmospheric precipitation.

Ondulin comes in regular sizes.

• thickness – 3 mm;
• width – 95 cm;
• length – 2 m;
• Wave height – 3.6 cm.

The Euro-Shifle’sprimarytechnical features are as follows:

• Fire safety class KM5, which indicates its combustibility and unsuitability for medical and children"s institutions;
• the ability to withstand a load of up to 0.96 tons per 1 m²;
• immunity to alkalis, acids and oil refining;
• harmlessness;
• the ability to contact water without serious consequences;
• long service life;
• Coloring in red, brown, green or black tone, which makes it possible to create a multi -colored coating.

The advantages and disadvantages of the oniline coating

According to owner reviews, Ondulin’s primary benefit is its waterproof nature. The Euro-shifer’suniquecomposition just causes it to repel moisture from itself. Furthermore, the water droplets swiftly roll down without piercing the material because the nailing is limited to the highest points of the wave.

It’s thought that Ondulin has additional benefits.

• simple layout of the material on the roof;
• the ability to put sheets directly on the old coating;
• the weight of the sheet is only 6 kg (4 times less than that of the slate, which has the same area);
• the absence of the need to build a particularly strong roof structure under the light sheets;
• the ability to cut the material with an ordinary hacksaw on wood, slightly lubricated with oil;
• The ability to take in a curved state of any shape, which makes it an ideal option for the roof of an unusual configuration;
• noiselessness that no metal material can praise, clearly transmitting the sounds of rain;
• Favorable price, because Euro -shifer is cheaper than metal tiles.

Ondulin does, however, exhibit certain traits that indicate severe dissatisfaction. The following issues are the most frequently brought up by the owners of the Euro-Shifle roof:

• In severe cold, the material becomes fragile, and on a hot day it melts and exudes the smell of bitumen;
• The installation of the coating is possible only at a temperature of not lower than -5 °;
• You can’t step on the roof, otherwise it will break;
• Sheets cannot withstand the pressure of a large layer of snow, that is, they cannot serve as a roofing in regions with heavy snowfalls;
• the material is easily ignited, since it consists of organic substances;
• The coating soon loses its juicy color;
• The surface of the sheets is quickly affected by the fungus and is overgrown with moss.

However, in the emergence of some shortcomings of the Euro -shifter in most cases, it is necessary to blame the material, but the owner of the roof itself. The author of these lines more than once had to be convinced that the low strength of Ondulin is just a consequence of the wrong installation. For example, wanting to somehow save on the construction of the roof, the sheet of the euro-shifter is fixed by ten nails, and not twenty, as required. And other owners of private houses are trying to reduce expenses at the expense of the crate: they take fewer boards than they need, and lay them out at an impermissible large distance from each other.

Lifetime

Manufacturers of Ondulin claim that he can serve for fifteen years. But as the roof’s owners from the euro-shifter pointed out, with careful use, the material might not even need to be replaced in 30 years.

The Ondulin service If you follow these guidelines, you can extend time to 30–40 years:

• build a crate from strong boards or bars;
• use nails of only one manufacturer made of alloy steel and equipped with a wide plastic hat;
• do not save on the number of fasteners;
• make the ends of the slopes with tongs;
• Pull cornices with sophims.

The choice of Ondulin

The "Ondulin" tiles can be used on any kind of structure, including conical and dome-shaped roofs. However, choosing from the various varieties of this material can be challenging.

If covering a vaulted or level roof, classic Ondulin 10 waves in the size 200×95 cm should be used.

In contrast to the standard option, Ondulin "Smart" weighs less because it is made in a 195×95 cm format, despite having 10 waves. Since it has a locking lock that stops drops from seeping under the upper sheet of the overlap during an oblique downpour, this type of material offers far better moisture protection. Because Ondulin "Smart" indicates the fastener placement points, making installation much simpler, it is regarded as an improved version of the traditional euro-shifter.

Compact Ondulin tiles are another variant. This kind of roofing material is a true gem for intricate and compact roofs found on garages, arbors, and sheds. A sheet of eight waves weighs only 2.5 kg because of the compact euro-shifter’slengthof 100 cm and width of 75 cm.

An increase in the number of overlaps replenishes a reduction in the thickness of compact Ondulin. The final coating is therefore very durable.

All of the Ondulin variations have the same waves, despite the sheets’ varying sizes. This implies that multiple types of material can be used simultaneously on one roof. A clear benefit of this is that the roofer won’t have to endure hardships when constructing a complex roof or performing partial coating repairs.

Immediately during the Ondulin selection process, consideration should be given to instances such as:

• the dimensions of the sheet, which, when discrepancy with strict parameters, indicate the fake of the material;
• the number of waves (necessarily 8 or 10);
• the same thickness in all areas of each sheet;
• ideal quality of the sheet (absence of spots and subclans);
• the evenness of the application;
• The presence of a quality certificate.

Ondulin compatibility with different roofs

Ondulin can be used to cover any type of roof because it is a flexible material.

Single -toe roof

If the slope of the roof is at least 5 °, ondulin may be installed on it. If this requirement is not met, the material won’t be able to last the length of time the manufacturer claims it will and will find it more difficult to dry out on its own.

In order to cover the single-sided roof ondulin, the following conditions have to be met:

• use a cross -section of 5×5 cm for crate;
• put the elements of the crate every 45 cm if the roof is tilted to 15 degrees, or at a distance of 60 cm from each other, when the roof has a greater slope;
• lay out the first row of material in the cornice;
• Fix the sheets, gluing all the joints with a mounting ribbon.

Broken roof

Sharp angles cause the roof to break, which is regarded as a complex structure, but it has no bearing on how ondulin is laid. The material that is weaker than the metal tile is released from the load because of the angular structure of the structure because it is essentially snow-free.

The following guidelines must be followed in order to install ondulin on a damaged roof:

• The laying of the material begins from the upper part of the roof so that you do not have to walk along the already fixed sheets;
• In the lower area of ​​the structure, the lower row of material is laid out first of all;
• The upper row of the material at the junction of the two planes of the complex roof, if necessary, is cut with a hacksaw.

Septress roof

One can safely cover a tank roof made up of four identical triangular slopes with ondulin. Flexible material totally eliminates the negative effects of atmospheric precipitation because the unique shape of the roof prevents snow and moisture from building up on the surface.

Ondulin can be installed on a tent roof without any issues if you are aware of the following:

• With a slope of a slope of more than 15 °, the bars are placed in a step of 60 cm, and the sheets of ondulin are laid out with an overlap 17 cm;
• когда наклон кровли равен 10–15°, элементы обрешётки располагают на расстоянии 45 см друг от друга, а куски ондулина монтируют с нахлёстом 20 см;
• If the roof is tilted by 5-10 °, then the crate is made without gaps, and the material is fixed with overwhelming 30 cm;
• The installation of Ondulin begins on the leeward side of the roof;
• The first sheet is laid 2 cm above the cut boundaries, and its marking is performed along the rib of the diagonal rafter;
• The last sheet in the row is mounted in the same way as the first, but all other pieces of material are laid according to the standard scheme – with a side floor in one wave.

"Onduline roofing combines classic design with contemporary functionality, offering a stylish yet durable blend of French elegance." In addition to improving the visual appeal of any building, onduline roofs—which are distinguished by their characteristic corrugated design and vivid color selections—also provide outstanding weather resistance and long-lasting performance. For those seeking elegance without sacrificing dependability, Onduline roofing is a popular option because it is perfect for both residential and commercial buildings and offers a classy French flair that endures."

Installation of Ondulin

The following steps are involved in the installation of ondulin on the roof:

1. They look where the wind blows. For the starting point of work, the roof slope, which is located opposite to the direction of air flows, is taken.
2. The installation of ondulin begins from below, from the cornice. To do this, use the technology "ladder", that is, the first thing they put a whole sheet in the first row, then half a sheet in the second row, and even later – the first sheet of the third row. The chain of actions is repeated until the roof is completely closed with the material. If such an installation scheme seems complex, then ordinary linear technology is used, in which each line from the sheets of Ondulin is formed in turn. The edges of the sheets are blocked, focusing on the indicator of the slope of the roof. The side overflow can be one or two waves, and the end – from 12 to 30 cm.
3. The nails are first scored in the four corners of the sheet. Then the fasteners are inserted in the lower row where the top of each wave is located, except for the one that will be covered with an edge of another sheet. Then, the second and third row of nails are scored into the material, while the fasteners are necessarily immersed in the extreme waves, and in the rest – one time, in a checkerboard order. The extreme wave and upper row of the sheet remaining without fixation are fixed with nails after laying neighboring pieces of material.
4. A skate element is installed on the roof, the yendovs are designed and the forceps are fixed. A special filler is used to eliminate the gaps between the sheets and the skate element (and also the cornice).
