All Membranes at Risk from Ultraviolet Rays

Damaging effects of UV rays on air and moisture membranes that are exposed during construction. Air and moisture membranes are widely used in construction to keep buildings water-tight. They are applied to the roof and walls to keep the elements out during the construction process, and after being roofed and walled over, they continue to […]

Damaging Effects of UV Exposure on Air and Moisture Membranes

In many commercial construction projects the ordinary practice is to protect the work site by installing air and moisture protection membranes early. This practice does not account for damaging effects of ultra-violet (UV) rays on the membranes that are left exposed during construction. Standard building envelope membranes are fabricated out of synthetic polymers which are often not UV stabilized. Spray […]
