Despite the relatively short period of its use in construction, this roofing material is widely distributed on the world market and is used in the device of the finish coating of residential and non-residential buildings. Ondulin, the sheet size of which may differ from each other, is used to cover private houses and cottages, farm buildings and outbuildings, garages and sheds, summer cottages and summer kitchens, garages and balconies, sheds and gazebos, as well as winter gardens. Affordable ondulin is attractive to entrepreneurs and government organizations. It is used to cover pavilions in markets, small shops, stops for public transport, storage facilities and other structures.
When starting to install a roof from ondulin, you should first think about the amount of material. The result of an incorrect calculation may be a situation where you need to buy some amount of roofing material. In this case, it may happen that ondulin is on sale, the colors of which differ from the one you need. The required size may also be missing.
To avoid such troubles, it is better to immediately take into account the size of the sheets of ondulin, the parameters of which you will find in this article, and you will also be able to learn about some of the features of this topcoat.
Ondulin coating features
Ondulin, as a roofing, is used during the construction or repair of roofs in industrial, public, commercial and residential buildings.
In addition, due to its attractive appearance, varied colors and convenient size, ondulin roofing materials have gained popularity in the construction of coatings for trade pavilions and awnings. It is characterized by flexibility, ease of installation and a long service life.
Since the material has a small weight (approximately 3 kg per 1 square meter), it can be used in the repair of roofs, laying on an old deteriorated coating. Manufacturers give it a warranty period of 15 years, although in real life ondulin can be used for 50 years.
Unlike asbestos slate, this material is durable and reliable, because it does not contain any substances harmful to health.
Material characteristics
The production of ondulin consists in the fact that cellulose fiber is pressed into sheets in a form resembling ordinary slate. They are impregnated with special bitumen, and then coated with hardening synthetic resins and mineral pigments.
Thanks to organic matter, ondulin acquires a rigid base. Waterproofing is provided thanks to bitumen. Ondulin is impregnated with bitumen in layers in special vacuum chambers. After this procedure, the sheets are painted. Depending on the color, the sheets of material are divided into matte and glossy. Ondulin matte has an acrylic color and is rough to the touch. Glossy sheets look brighter in appearance. This is explained by the addition of silicone to the paint composition, which provides a glossy gloss and color of the material.
Ondulin glossy is sold at a higher price than matte. He does not hold onto himself the falling snow and settling mud. For this reason, glossy ondulin is more attractive in appearance. The basis of the material is environmentally friendly components that do not contain harmful impurities, such as asbestos, a carcinogen dangerous to human life.
This technology of material production affects:
- aesthetic appearance of the material;
- protective characteristics;
- life expectancy.
When manufacturing ondulin, the manufacturer usually produces sheets of standard size. Allowable error should fluctuate within 2-5 millimeters. As a rule, roofing material has the following parameters:
- length - 2 m;
- width 0.95 m;
- thickness 3 mm;
- wave height 36 mm;
- the weight of one sheet of ondulin is 6 kilograms.
Some developers, when determining the required amount of material, take into account only the overall dimensions of the sheet, forgetting that when carrying out installation works, nails for ondulin are used and sheets are overlapped in the transverse and longitudinal directions. The usable area is reduced to a size of 1.6 square meters. For example, to equip a roof with an area of 100 square meters with a slope of the roof slope of 15 degrees, 63 sheets and plus 8 ridge elements will be needed.
Such calculations are suitable in the case when a finish coating of a gable roof of a simple form is made, which does not have architectural difficulties.
Benefits of Using Ondulin
The widespread use of this roofing material in the construction of many countries is due to a number of advantages that do not depend on what size ondulin has for the finish coating:
- sheets can withstand the load from the fallen snow up to 300 kilograms per 1 square meter;
- roofing material is able to withstand winds with a force of 200 kilometers per hour;
- such a topcoat has the ability to absorb the noise that makes rain and hail;
- it is resistant to temperature extremes;
Features of Ondulin - resistance to bending is possible due to the properties of the material and the ability to use nails for ondulin;
- ondulin perfectly tolerates mechanical shocks and is resistant to acid exposure;
- due to the multilayered material and the wavy shape of the sheet, the bearing capacity of the material reaches 650 kilograms per 1 square meter;
- the sheets of ondulin have sufficient strength, since when it is pressed, layer-by-layer intersection of fibers occurs;
- the material has excellent water resistance;
- it is possible to exploit the roof from ondulin with fluctuations in air temperature from -40 to +80 degrees.
Due to the low level of water absorption, ondulin is able to withstand up to 100 freezing and thawing cycles without disturbing the structure of the material. In addition to ease of operation and installation, when nails for ondulin are used for fastening sheets, the material has a variety of colors.
Many developers prefer ondulin to another roofing material because of its ability to bend well in any direction. Thanks to this property, the installation of the topcoat on roofs with complex geometry is facilitated.
In general, ondulin can be attributed to a universal roofing, which has a relatively low cost and excellent characteristics in installation and operation.
