Bituminous membrane is a waterproofing material used in most applications for sealing and insulating flat roofs. Thanks to its excellent performance and ease of application, it is considered one of the most reliable and fastest solutions for roof insulation.
In general, bituminous membranes are classified into different categories according to their density, their flexibility at sub-zero temperatures, their resistance to continuous thermal expansion and contraction, and their reinforcement. Externally, they are usually coated with grey or white mineral granules, which protect them from solar radiation and extend their service life.
