The spread of individual construction is an auspicious moment for the emergence of new materials. Ondulin, the technical characteristics of which allow it to be used for roofing, is one of the latest 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 it.
2. Ondulin contains no asbestos hazardous to he alth.
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.
5. The manufacturer's warranty on the material is 15 years.
6. Ondulin, the technical characteristics of which 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 made of ondulin is complicated by the fact that it is undesirable to move on the finished base.
2. After the completion of the roofing device from this material, a space remains at the junction of the slopes, which requires additional sealing. This must be taken into account when drawing up an estimate.
3. Poor-quality material of different colors may undergo uneven fading over time. In order to prevent loss of aesthetic appeal of the roof, you should only buy 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 using it in medical institutions, schools and kindergartens, fire barriers must be provided to localize the fire.
Dimensions and weight of ondulin sheets
Standard sheet length is 2000mm, width is 950mm, thickness is 3mm. Ondulin is a relief material, the wave height is 36 mm. The useful sheet area is 1.29-1.56 m2 depending on the slope of the roof. Ondulin Smart, whose characteristics are similar to the traditional type of material, differs from it in two extruded strips along the edges of the sheet. This system reduces the overlap by 50 mm.
The weight of each sheet is relatively small - 6 kg. This indicator makestransportation and installation of the material is simpler. When working with it, you do not need to use special equipment. This is another advantage that ondulin has. Specifications, dimensions and material properties allow installation with a hammer and a hacksaw.
The benefits of using Ondulin Smart
1. The smart lock system makes installation easy.
2. Ondulin Smart, whose characteristics are better than its traditional counterpart, due to less overlap, allows you to reduce the weight of the roof and its cost.
3. Sheets of material have markings for attaching nails.
Production technology and composition
The raw materials for the production of ondulin are cellulose fibers, pure bitumen, mineral fillers, resin and dyes. The composition of the material does not contain synthetic impurities.
Technological process involves the impregnation of cellulose fibers with bitumen. Their subsequent pressing gives shape to future sheets. To protect against external influences, mineral-based paints and resins are used. They allow the material to retain 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. Instructions always reflect installation specifics 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. Lowthermal conductivity, which is especially important in the northern regions of the country. It equals 0.19-2.0 kcal/mh°C.
3. Excellent noise isolation, which reaches 40 dB. This is much higher than metal tiles.
4. Resistance to negative temperatures. After repeated cycles of freezing / thawing, the sheet does not change its geometric dimensions.
5. An adult can bend ondulin. The characteristic of the material for such a property as strength is positive. It does not deform during installation.
Scope of application of ondulin
This material is widely used in private construction for roof construction. Many owners choose it because the dismantling of the old coating can be avoided. The light weight of the ondulin slightly increases the load on the building structure.
Recently, railings and balconies have been made from this relief material. Peaks and awnings are also made from it.
Reviews of owners of private houses
Today you can often find reviews of ondulin. Most often these are positive characteristics and recommendations regarding the purchase of this material. But there are also negative statements.
Manufacturers and sellers claim that the material does not crumble, does not crack, does not melt in the sun and retains its size in all conditions. But in some cases, the ondulin sheet loses its integrity during normal cleaning of gutters. This is usuallycausing outrage among homeowners and critical reviews.
The reason for this behavior of the material is most often a violation of the technology of its installation. For example, each sheet of ondulin must be fixed with twenty special nails. Only this number of fixation points ensures the strength of the resulting frame. Violation of this requirement, combined with ignoring the recommendations for roofing 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 gets very hot in direct sunlight. Manufacturers themselves warn about this phenomenon in detailed instructions for the installation and operation of the material.
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 written in the instructions, is often criticized because of the strong burning. Attentive buyers always know this, as they read all the documentation before buying. The combustibility of the material is due to its organic composition. Special impregnations do not allow the roof to flare up from an unextinguished match, and an open flame is already becoming reala threat to the roof.
In closing
So, ondulin, the technical characteristics of which were discussed in this article, is a new generation roofing material. It has a lot of advantages. But before buying, you need to carefully familiarize yourself with its shortcomings.
