Weather-Resistive Barrier (WRB)
System Description
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.

Weather-Tech WeatherSeal Spray & Roll-On is a vapor-permeable liquid applied water-resistive barrier and air barrier. The product provides superior moisture protection compared to paper based WRBs as it can not rip or tear which would leave the substrate exposed and unprotected. Additionally, Parex USA Weather-Tech WeatherSeal Spray & Roll-On is a 2 product system making is easier to use when compared to other liquid WRBs on the market today. Simply use Parex USA Sheathing Tape with Weather-Tech WeatherSeal Spray & Roll-On to treat joints and then apply Weather-Tech WeatherSeal Spray & Roll-On to cover the substrate. As the name implies, the product can be sprayed or roller applied making it application easy.
WeatherSeal Trowel-On is a vapor-permeable liquid applied water-resistive barrier and air barrier. The product provides superior moisture protection compared to paper based WRBs as it can not rip or tear which would leave the substrate exposed and unprotected. Additionally, Parex USA WeatherSeal Trowel-On is a 2 product system making is easier to use when compared to other liquid WRBs on the market today. Simply use Parex USA Sheathing Tape with WeatherSeal Trowel-On to treat joints and then apply WeatherSeal Trowel-On to cover the substrate.
