House Wraps
RadWrap™
General:
Polyshield RadWrap foil/white, 95% reflective, perforated house wrap material has many applications. It is generally known for its superior performance as a Vapor Barrier, a Moisture Barrier, and an insulated house wrap. Polyshield RadWrap consists of a highly reflective material that reflects radiant heat rather than absorbing it. Appling RadWrap to your sidewalls can improve the efficiency of traditional insulation by 50% based on independent laboratory studies.
Energy efficiency:
Polyshield 8.5′ material was designed specifically as a house wrap, increasing your R-value, improving energy efficiency. The 95% Radiant Heat reflectivity when installed against 1″ of air space provides a constant R value of R4.5. Thus, the additional R value to exiting walls R value improves the house/building Over All Thermal Transmission Value (OTTV) and energy optimization passive solution.
