In this case, we are talking about the reverse seal.
Specifications
Roof sealant should have a density between 30 and 35 kg/m3, it acts as an excellent waterproofing, but the water absorption is 1.5% or less. The material is microbiologically stable, which means that it does not mold or rot, and is also resistant to aggressive environments, its surface can be affected by oil and gasoline, to which it remains inert.
The seal is environmentally and hygienically safe, including for human he alth and the environment. The material is elastic, light, which has a positive effect on installation, and elastic.
Products can be easily cut, glued with special compounds, welded with a building dryer and soldering iron. Products are supplied with double-sided tape, so they are easy to fix on the surface, this can also be done with the help of staples of a construction stapler, which are sometimes replaced with nails. The durability of such products is truly enormous and reaches 90 years, whilethe material retains its operational properties. The sealant can be used in a wide temperature range, which varies from -60 to +95 °C. The seal complies with fire safety regulations and is moderately flammable and flame retardant.
Types of roof seals
