Today, one of the most popular roofing materials is ondulin. Sheet size, resistance to stress and light weight make working with it convenient.
Ondulin is a wavy fabric made from compressed cellulose, which is impregnated with bitumen. Builders also call this material Euroslate. Its color depends on the variety of bitumen. To improve the characteristics of the material from above, 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, this facilitates the work with it and the rise 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 a suitable shade in harmony with the site.
5. Flexible curved sheets are not affected by fungi, bacteria and other microorganisms.
6. Ondulin does not absorb moisture, but completely rejects it.
Scope of ondulin
Most often, ondulin, the sheet size of which allows accurate cost estimates, 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.
On the roofs of small shopping pavilions and shops you can also see ondulin. 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 performed without closing the store.
Standard sizes and weight of the ondulin sheet
Ease of use of ondulin is to standardize the sizes of 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 smaller than the overall, are 950 x 2000 mm. The tolerance in width is ± 5 mm, in length - +10 mm. Sheet thickness - 3.0 mm. Wave height - 36 mm. The weight of the standard sheet is 6.0 kg.
About what size of the sheet of ondulin will remain useful, if you put it with an overlap with adjacent elements of the roof, you need to tell additionally. A gable roof with a small angle of inclination implies laying the roof with overlapping length and width. The dimensions of the usable area of the sheet in this case are approximately 864 x 1900 mm.
It is worth considering that when installing a roof with complex bends, the material consumption can significantly increase. The standard size of the ondulin sheet in this case is divided longitudinally into 2-3 parts. An overlap is made at the junction of each element.
In the cost estimate for the arrangement of the roof, it is necessary to include not only the cost of materials and work of the installers, but also additional elements. For example, skates, rain gutters and other accessories.
Standard sizes and weight of Smart ondulin sheet
The market of roofing materials is constantly updated with new products. This also applies to ondulin. A new generation of Smart roofing is gradually replacing it.
Advanced ondulin differs from its predecessor by the presence of markings on the sheet. The extruded stripes help to more accurately carry out the installation. Ondulin "Smart", the sheet size of which has become a little different, can reduce the overlap size by about 50 mm (from 170 to 120 mm). Such a measure facilitates installation.
The specially developed Smart Lock system slightly resized sheets to 950 x 1950 mm instead of 850 x 2000 mm. The usable area has increased. The weight of the improved sheet of material is already 6.3 kg instead of 6.0 kg.
Reviews of owners of houses with an ondulin roof
Some owners of private homes a few years after installing the roof begin to complain that the roof falls under your feet when walking and soaks over time from the rains. Upon a more detailed examination, it turns out that instead of the durable ondulin, customers sold ordinary pressed cardboard coated with paint of a suitable color. Unscrupulous manufacturers who want to sell more materials do this. As a rule, such claims do not arise 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 should definitely not sunbathe or arrange a garden.
Also, 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.
Features of roof maintenance from ondulin
High-quality roofing material does not require special permanent care. To prevent damage to property, it is advisable to clean the roof from snow and pollution. Ondulin, the size of the sheet of which varies depending on the fastening system, is in some cases prone to fading. The roof coating with special paint will help to cope with this.
Thus, ondulin, the sheet size of which is standardized, today is one of the most modern and common roofing materials. The Smart mounting system helps ease its installation. In the future, the popularity of ondulin will only grow.
