What is PSMB?
PSMB’s full name is Polysurlyn Moisture Barrier, which is a multi-layer material. Moisture barrier and thermal insulation layer on the inner surface of metal building panels usually use it. PSMB usually consists of two layers: a layer of mill finish aluminum coil and a layer of polysurlyn. Aluminum coil acts as vapor barrier while the polysurlyn layer provides additional durability and protects the aluminum from punctures or tears.
