Siplast, a leader in advanced building envelope systems, introduced the WALLcontrol Monolith VP Adhered AWB, an addition to its existing WALLcontrol air and water-resistive barrier systems portfolio. The WALLcontrol Monolith VP Adhered AWB is a self-adhered, vapor-permeable air- and water-resistive barrier.

Vapor permeable membranes reduce risk of moisture accumulation related to air leakage.

The ways in which liquid and vapor move through our building envelopes are complex, and even today not completely understood; but the fact that lots of water can (and does) move through porous building materials is a phenomenon that rules over so much of the way we build.
