GCP Applied Technologies has launched Perm-ABarrier VPL50, a permeable, liquid-applied air barrier designed to protect building structures from air and liquid ingress. The roller-applied membrane includes rain-resistant silyl-terminated polyether (STPE) technology, which does not wash off when exposed to light rain, the company says. GCP’s Perm-A-Barrier VPL50 forms a seamless barrier that helps minimize energy loss and weather delays, according to the company. Pricing varies. gcpat.com/en/solutions
