MFM's WindowWrap effectively stops water leaks around windows and doors while reducing outdoor noise and air infiltration. The aggressive adhesive securely bonds the window flange to the exterior wall, and the rubberized asphalt self-seals around nails and staples. Designed for the professional homebuilder – where construction delays are common – the tough, durable, aluminized surface of WindowWrap is unaffected by UV exposure for a minimum of 6 months after being applied to the window! Aggressive Broad Temperature Spectrum (BTS) adhesive adheres to common window and building materials and remains flexible in low temperatures.
