Universal seal for metal

Modern sealant for metal roofing is made for existing roofing. It can have a shape that coincides with the shape of the wave of the covering material. This material is intended for sealing gaps. It allows you to exclude the penetration of moisture, dirt and snow, as well as small branches and fallen leaves under the shingles.

Description

The compactor for metal tiles has ventilation cuttings, which ensures ventilation of the inner layer and proper operation of the roofing cake. These seals can be made of foamed polyvinyl chloride, which has the qualities of elasticity and lightness.

In addition, this material has closed pores. It is moisture resistant, which allows you to retain quality for several decades, even if it is constantly affected by water. The sealant does not decay, is resistant to various effects, is environmentally friendly, harmless to the environment and has insulating qualities.

The main varieties

The compactor for metal tiles can be classified into two varieties. The first is intended for laying between a profiled coating and a ridge and is called a straight seal. The second is placed between the cornice and the profiled base, as well as in the junctions. Its name is the reverse seal.

Main characteristics of the sealant

The density of the sealant can vary up to 35 kg / m ³ . It has excellent waterproofing properties. This indicates that the water absorption does not exceed 1.5%. The material is microbiologically constant, indicating that it is resistant to mold and rot, aggressive media, and chemicals.

The compactor for metal tile can contact with gasoline and oil, without losing its quality characteristics. We can not forget about ecological and hygienic safety, because products that are harmless to the environment are very much appreciated today.

This material is elastic and elastic, which facilitates installation work. Products are quite easy to cut, as well as welding with a soldering iron and a construction hair dryer. The material can be glued with special formulations or double-sided adhesive tape. As an alternative solution for fixing, you can use nails or a furniture stapler.

The sealant under the metal tile has durability, it is able to maintain its performance for a long time. In some cases, the manufacturer speaks of 90 years, during which the material will not require replacement.

The temperature range of operation is quite wide and is measured in the range from -60 to +95 ° C. For private homes, fire safety standards are also important. The sealant under the shingles of metal tiles belongs to class G2, which makes the material moderately flammable or hardly inflammable.

Description of the sealant for the ridge of metal

As one of the important components of the drainage system of buildings of any purpose is the ridge seal. It excludes the penetration of atmospheric precipitation under the roof and into the room. If you own a private house whose roofing is poorly sealed, then you should be aware of the problem of roof pie leaks, which leads to the need for annual repairs.

The use of this element allows to extend the operational lines of the rafter system and heat-insulating materials. Seals are mounted between the metal roof and the ridge, as well as the base of the roof, even before the master starts the installation. This is especially important for tent roofs, when the sealing element is installed diagonally relative to the roof slope.

Types of ridge seal

Ridge compactor for metal tile can refer to one of three types, namely to self-expanding, universal and profile. The first variety is made of polyurethane foam, which is impregnated with polymer during production. As the last can act acrylic. To fix the seal on the surface of the element there is a self-adhesive strip. Ideally self-expanding parts are suitable for cracks in the arrangement of the roof.

The sealant for the ridge of metal can be universal. In this case, polyurethane film is used in the production process, which acts as a filter. Through it, air can freely penetrate, but the material excludes the accumulation of excess moisture, not skipping snow and dirt, as well as foliage.

As for the profile devices, they are made of expanded polyethylene.

Need to use a sealant

Many consumers are wondering why it is necessary to use a sealant for metal roofing if the elements are so tightly pressed together. The answer lies in the fact that the sheets are close to each other, so that the seams are not noticeable, there are still gaps between the additional elements of the metal tile. This is due to the fact that the Finnish and Russian metal tiles profile is performed in the form of a wave. This feature is the main distinctive quality of the material for the roof.

The additional elements in the form of a ridge and valley have a straight profile, so large holes remain between the wave and the plane, the width of which is 150 mm, while the height is 20 to 30 mm. Thus, the seal is installed from both sides of the profile to the hinge, on both sides of the valley, and also on one side of the wall and wind bars.

Conclusion

The question is whether many water can get into the space under the roof, because the covering material comes under the skate by 5 cm or more, while the slopes are inclined. If there is no wind, then moisture will not fall, but if it is very strong, then the water will be driven inside. Rain water will fall under the roof, as for snow in winter, which is driven even into the smallest cracks.
