Today one of the most popular roofing materials is ondulin. The sheet's size, load-bearing capacity and light weight make it easy to handle.
Ondulin is a wavy fabric made of compressed cellulose, which is impregnated with bitumen. Builders also call this material euroslate. Its color depends on the type of bitumen. To improve the characteristics of the material on top, it is additionally treated with thermal oils and minerals, in combination they provide protection against moisture.
Ondulin properties
1. The material is resistant to adverse environmental influences. Manufacturers claim that the roof of it will serve at least 50 years.
2. The ondulin sheet has a weight of only 6 kg, which makes it easier to work with it and climb to a height.
3. The roof of this material has excellent heat and sound insulation properties.
4. Ondulin has an attractive appearance. A variety of colors makes it possible to choose the right shade that is in harmony with the site.
5. Flexible curved sheets are not affected by fungi, bacteria and othermicroorganisms.
6. Ondulin does not absorb moisture, but completely rejects it.
Scope of application of ondulin
Most often, ondulin, the sheet size of which allows you to accurately estimate costs, is used in private construction. It can be found on the roofs of both small cottages and two-story houses.
Recently, ondulin is found in multi-storey residential buildings, schools and clinics. Builders choose this type of roofing material because of the ease of installation.
Ondulin can also be seen on the roofs of small trade pavilions and shops. The choice of roofing material in this case is explained by the possibility of laying it on top of the old slate. This method of updating the roof can be done without closing the shop.
Standard dimensions and weight of an ondulin sheet
The convenience of using ondulin lies in the standardization of the dimensions of the sheets of material. This allows you to accurately calculate its consumption.
On curved and curved roofs it is best to use ondulin. The dimensions of the sheet, the usable area of which is always less than the overall area, are 950 x 2000 mm. The width tolerance is ±5 mm, the length tolerance is +10 mm. Sheet thickness - 3, 0 mm. Wave height - 36 mm. Standard sheet weight is 6.0kg.
About what size of the ondulin sheet will remain useful if it is overlapped with neighboring roof elements, you need to tell more. A gable roof with a slight angle of inclination implies laying a roof with an overlap in length and width. Usable dimensionssheet area in this case is approximately 864 x 1900 mm.
It should be borne in mind that when installing a roof with complex bends, material consumption can increase significantly. The standard size of an ondulin sheet in this case is divided longitudinally into 2-3 parts. An overlap is made at the junction of each element.
The cost estimate for the arrangement of the roof should include not only the cost of materials and the work of installers, but also additional elements. For example, skates, rain gutters and other accessories.
Standard dimensions and weight of "Smart" ondulin sheet
The roofing materials market is constantly updated with new products. This also applies to ondulin. It is gradually being replaced by a new generation of Smart roofs.
The improved ondulin differs from its predecessor by the presence of markings on the sheet. The embossed strips help to make the installation more precise. Ondulin "Smart", the sheet size of which has become slightly different, allows you to reduce the amount of overlap by about 50 mm (from 170 to 120 mm). This measure facilitates installation.
The specially designed Smart Lock system has slightly changed the dimensions of the sheets to 950 x 1950 mm instead of 850 x 2000 mm. At the same time, the usable area has increased. The weight of the improved material sheet is already 6.3 kg instead of 6.0 kg.
Reviews of owners of houses with ondulin roofing
Some owners of private houses a few years after the installation of the roof begin to complainthe fact that the roof falls under your feet when walking and gets wet over time from the rains. Upon closer inspection, it turns out that instead of a durable ondulin, customers were sold ordinary pressed cardboard coated with paint of a suitable color. So do unscrupulous manufacturers who want to sell more materials. As a rule, there are no such claims to the original ondulin.
To prevent premature loss of roofing properties, you should move along it only with the help of special ladders. On such a roof, you definitely should not sunbathe or arrange a garden.
Also, even during installation, you need to take care of high-quality insulation of chimneys. Such a measure will help prevent the occurrence of a roof fire.
Ondulin roof maintenance features
Quality roofing material does not require special constant care. To prevent damage to property, it is desirable to clean the roof of snow and dirt. Ondulin, whose sheet size varies depending on the fastening system, is subject to fading in some cases. Covering the roof with special paint will help to cope with this.
Thus, ondulin, whose sheet size is standardized, is today one of the most modern and common roofing materials. The "Smart" fastening system helps to facilitate its installation. In the future, the popularity of ondulin will only grow.
