Roofing sealant is made today for all existing materials that are used in the arrangement of roofs. It should have a shape that matches the waveform of the corrugated board. This element is intended for sealing gaps, preventing the penetration of dirt, snow, water, fallen leaves, as well as small branches. It can be used in conjunction with sandwich panels, tiles or decking. The seal must have ventilation cuts that provide ventilation of the insulation layer, guaranteeing the correct operation of the structure. This, in turn, creates a normal microclimate inside the house and extends the life of the structure.
Description
Seals are made of foamed LDPE, which is an elastic and lightweight material with closed pores. The material is moisture resistant, it allows you to maintain performance when in contact with water. The sealant does not rot, it is resistant to chemicals and is an environmentally friendly insulating material that does no harm to the environment.
Appointment
The roofing sealant can be used to isolate the gaps between the profiled product and the ridge, in which case a direct sealant, also called ridge sealant, is taken. These products are also used for laying between the cornice, as well as the profiled product, in those places where the elements are adjacent to each other. In this case, we are talking about a reverse seal.
Specifications
The roof seal must have a density in the range of 30 to 35 kg / m 3 , it acts as an excellent waterproofing, but the absorption of water is 1.5% or less. The material is microbiologically stable, this indicates that it is not moldy and does not rot, and is also resistant to aggressive environments, oil and gasoline, to which it remains inert, can act on its surface.
The sealant is environmentally and hygienically safe, including for human health and the environment. The material is resilient, lightweight, which positively affects the installation, and elastic.
Products are easily amenable to cutting, gluing with the help of special compounds, welding with a building hairdryer and a soldering iron. The products are supplied with double-sided tape, so they can be easily fixed to the surface, this can also be done using the staples of a building stapler, which are sometimes replaced with nails. The durability of such products is truly enormous and reaches 90 years, while the material retains its operational properties. The sealant can be used at a wide temperature range, which varies from -60 to +95 ° . The sealant complies with fire safety standards and is moderately flammable and non-flammable.
Types of roofing seals
It is not difficult to purchase a roofing sealant today, the main thing is to choose the right product that will perform its functions. For example, on sale you can find sealing tape, which is intended for corrugated board. It is made of polyurethane foam or foamed LDPE. Products repeat the shape of the base material, such as metal tiles or corrugated board.
In order to speed up installation, an adhesive layer can be applied to the surface of the material. To ensure adequate ventilation, the seal is equipped with process holes. Another variety is a universal sealant, which has a rectangular section, it can be combined with a roofing of any shape. It is usually used for cornice or cognac and is made of flexible polyurethane foam.
For sale, manufacturers also offer consumers a self-adhesive sealant, which differs from the standard version in that it has an adhesive layer. Among other things, the finished product may be direct or reverse. In the first case, the installation is carried out between the ridge and the profiled product, while in the second installation is carried out at the junction of the profiled sheet and the cornice. The described products can also have a pronounced purpose. For example, you can meet the roof seal of the chimney or end seal, the last of which is used at the junction of the roof and pediment. An analogue is a sealant for laying in valleys, it is used at the joints of the formation of the inner corner and the covering material.
Overview of the features of the corner flash roof seal Master Flash No. 1
If you are interested in a roof sealing corner, then you may prefer Master Flash No. 1, which will cost 1600 rubles. The product is intended for a roof, the slope of which varies from 20 to 55 °. The diameter of the contour can vary from 75 to 200 mm. Using this sealant, it is possible to seal those places where pipes with diameters ranging from 75 to 203 mm pass. It is based on EPDM rubber, which can be used at temperatures ranging from -55 to +135 ° . The material is elastic, it can be laid as tightly as possible on the surface with any configuration. Such roofing pipe seals dampen vibration and displacement of elements that could be caused by expansion and contraction. When using these products, the pressure of the mass of snow, which accumulates on the roof surface, is also reduced.
Reviews on the installation features of the roof corner seal
Universal roofing sealant, as well as angular, should be selected so that the hole is 20% smaller than the diameter of the pipe. According to customers, if necessary, it must be cut off, and then put on the connecting pipe using a soap solution, which will facilitate the work. The edges must be pressed down in the shape of the roof, if necessary, use the tool. Users are advised to apply sealant under the flange, and at the final stage, screws are used to fix the screws, which fix the product to the base. The distance between the fasteners should be 35 mm.
Conclusion
The sealant of roof passages is an irreplaceable element at arrangement of a roof pie. It is impossible to create a reliable design without its use; it allows you to seal the gaps that arise during operation. It can be used for the installation of metal tiles, bitumen and profiled sheets. Using the material, it is possible to organize effective protection of the space under the roof from the negative effects of external factors.
