Development history of waterproof and breathable membrane


In the 1950s, German architects found that the self-adhesive and airtight characteristics of asphalt waterproofing membrane and coating waterproofing materials led to the residual water in the concrete structure being enclosed in the structure, and the water vapor in the concrete structure could not be released, which led to the breeding of mold on the roof and wall, and the indoor air quality and human health were seriously threatened. Therefore, the German construction industry began to use the roof cushion with air permeability to replace the self-adhesive coiled material and film waterproof. This air permeability cushion is laid on the roof base layer, so that the water vapor of the cast-in-situ concrete roof panel can be quickly discharged, thus avoiding the breeding of mold.

What are the advantages of laying waterproof and breathable membrane on sloping roof?


The waterproof and vapor permeable membrane on the sloping roof not only strengthens the water tightness of the building, but also makes the water vapor of the structure discharge rapidly, protects the thermal performance of the enclosure structure, avoids the breeding of mold on the roof, and improves the air quality of the room.
