Water-Resistive Barriers (WRB)

Parex USA offers a number of Water-Resistive Barrier products to meet various design needs. Known as our WeatherTech WRBs these products are all liquid applied and also act as an air barrier. Liquid applied barriers are superior as there is no risk of rips or tears which can significantly compromise the effectiveness of typical building papers. These product also have the added benefit of being an air barrier. Significant amounts of energy can be lost in a structure purely by the escape and intrusion of air. This decreases the energy required to maintain the desired temperature which saves money. The US Department of Energy estimates that uncontrolled air leakage can account for 30% or more of a buildings energy losses.
