Vapor barrier

Humidity cannot be avoided in homes. In Canada, homes need to be heated in winter and air conditioned in summer. There is a risk that traditional polyethylene vapor retarders trap humidity inside walls during the summer, thereby accentuating the risk of mold problems, structural damage, health problems and civil liability. The continuous air barrier provided by MemBrain™ is patented; the same product supplies a continuous protection against air and sophisticated humidity management.
