Distribution of individual construction is a favorable moment for the emergence of new materials. Ondulin, whose technical characteristics allow it to be used for roofing, is one of the latest in production. It is produced according to European quality standards.
Benefits of using
1. The color of the sheets remains saturated for a long time. This is possible due to the special impregnation of the material before painting.
2. Ondulin does not contain asbestos hazardous to health.
3. The material is resistant to corrosion, chemicals from precipitation and decay.
4. Ondulin is not afraid of prolonged exposure to sunlight, frost and high temperatures. It is also resistant to the spread of fungi and other microorganisms on it.
5. The manufacturer's warranty on the material is 15 years.
6. Ondulin, whose technical characteristics will be discussed below, has low water absorption, which once again proves its suitability as a roof.
7. Manufacturers claim that the service life of the material is 50 years.
Disadvantages of using
1. Installation of a roof from ondulin is complicated by the fact that it is undesirable to move around on a finished basis.
2. After the completion of the roofing of this material, a space remains at the junction of the slopes, which requires additional sealing. This must be taken into account when drawing up estimates.
3. Poor quality material of different colors may be subject to uneven burnout over time. In order to prevent the loss of the aesthetic attractiveness of the roof, you need to buy only products from well-known manufacturers with an excellent reputation.
4. Ondulin refers to combustible materials. During production, it is subjected to special impregnations that reduce this figure. When used in medical institutions, schools and kindergartens, it is necessary to provide fire barriers to localize the fire.
Dimensions and Weight of Ondulin Sheets
The standard length of the sheets is 2000 mm, width - 950 mm, thickness - 3 mm. Ondulin is a relief material, the wave height is 36 mm. The usable area of the sheet is 1.29-1.56 m 2 depending on the inclination of the roof. Ondulin Smart, whose characteristics are similar to the traditional type of material, differs from it by two extruded stripes at the edges of the sheet. Such a system reduces overlap by 50 mm.
The weight of each sheet is relatively small - 6 kg. This indicator makes transportation and installation of the material easier. When working with him, you do not need to use special equipment. This is another advantage that ondulin has. Technical characteristics, sizes and properties of the material allow installation with a hammer and a hacksaw.
Benefits of using Ondulin Smart
1. The smart lock system facilitates the installation process.
2. Ondulin Smart, the characteristics of which are better compared to the traditional analogue, due to less overlap, it allows to reduce the weight of the roof and its cost.
3. Sheets of material have a marking for fastening nails.
Production Technology and Composition
The raw materials for the production of ondulin are cellulose fibers, pure bitumen, mineral fillers, resin and dyes. The material contains no synthetic impurities.
The technological process involves the impregnation of cellulose fibers with bitumen. Their subsequent pressing gives shape to future sheets. Mineral-based paints and resins are used to protect against external influences. They allow the material to maintain its shape and color for a long time.
Ondulin: specifications, reviews and identified shortcomings
Manufacturers do not make a secret of the characteristics of ondulin. The instructions always reflect the installation features associated with certain material properties.
Physical and mechanical characteristics of ondulin
1. The material is resistant to temperatures up to 110 ° C. In this range, it retains its shape and properties.
2. Low thermal conductivity, which is especially important in the northern regions of the country. It is 0.19-2.0 kcal / mh ° C.
3. Excellent sound insulation, which reaches 40 dB. This is much higher than that of metal.
4. Resistance to freezing temperatures. After repeated freeze / thaw cycles, the sheet does not change its geometric dimensions.
5. An adult can bend ondulin. The characteristic of the material by such a property as strength is positive. It does not deform during installation.
Scope of ondulin
This material is widely used in private construction for the construction of roofs. Many owners choose it because the dismantling of the old coating can be omitted. The light weight of ondulin slightly increases the load on the building structure.
Recently, fencing and balconies have been made from this relief material. Visors and awnings are also made from it.
Responses of owners of private houses
Today, you can often find reviews about ondulin. Most often, these are positive characteristics and recommendations regarding the purchase of this material. But there are also negative statements.
Manufacturers and sellers argue that the material does not crumble, does not crack, does not melt in the sun and remains constant in all sizes. But in some cases, the ondulin sheet loses its integrity during the usual cleaning of gutters. This, as a rule, provokes indignation of homeowners and leads to critical reviews.
The reason for this behavior of the material most often becomes a violation of the technology of its installation. For example, each sheet of ondulin must be fixed with twenty special nails. Only such a number of fixation points ensures the strength of the resulting frame. Violation of this requirement in combination with ignoring recommendations for the installation of a roof at a certain angle leads to such sad consequences as cracks and deformations.
The real disadvantages of ondulin
Of all the critical statements about ondulin, only a few are true. It heats up very much in direct sunlight. Manufacturers themselves warn of this phenomenon in detailed instructions for the installation and operation of the material.
In order to avoid injuries and other unpleasant consequences associated with the phenomenon of strong heating, it is necessary to minimize the time spent on the roof and move at a height only on a special ladder, that is, do not touch the material.
Ondulin, the technical characteristics of which are prescribed in the instructions, is often criticized due to strong burning. Attentive buyers always know about this, as they have read all the documentation before buying. The flammability of the material is explained by its organic composition. Special impregnations do not allow the roof to flare up from an unquenched match, and an open flame is already becoming a real threat to the roof.
Finally
So, ondulin, the technical characteristics of which were considered in this article, is a new generation of roofing material . It has a lot of advantages. But before buying, you need to carefully familiarize yourself with its shortcomings.
