Palisade® Premium Building Wrap is a 100% synthetic building wrap and an integral part of the Palisade® Air & Moisture Management System that ensures superior builder and owner satisfaction. It contributes to weather-tightness and provides energy efficiency in buildings for the life of the structure. The building wrap is a non-woven, nonperforated polypropylene fabric that provides the ideal ratio of water resistance vs. moisture vapor transmission to the outside. Thus, it lets the structure breathe while preventing damage due to water infiltration. It does not absorb or retain water.
