Premium Protection and Superior Energy Efficiency

Homebuilders today are faced with a number of new challenges, including increased demand for energy efficiency, stricter air leakag​e requirements, and the rising costs o​​f installation. Choosing the correct weather protection system is an important decision. Vycor® enV-S™ self-adhered weather resistive barrier (WRB) makes that decision easier. ​​ ​
Vycor® enV-S™ self-adhered membrane provides premium weather protection and breathability that preserves the home's structural integrity. Unlike mechanically-attached house wraps, Vycor® enV-S™ seals t​o itself, seals around fasteners, and forms a strong adhesion with the substrate, even when exposed to harsh weather conditions, eliminating costly rework. And, most importantly, Vycor® enV-S™ WRB improves the home's energy efficiency, leading to significant energy savings for the homeowner.

Homeowners Save Money with Vycor® enV-S™ Weather Resistive Barrier​


A recent study conducted by the Oak Ridge National Laboratory (ORNL) revealed that Vycor® enV-S™ WRB achieved an air leakage rate seven times lower than the leading house wrap brand in all regions of the United States. A reduced rate of air leakage translates to lower annual heating and cooling costs—an important benefit that homeowners will surely value and appreciate.

The interactive map below illustrates the findings from ORNL's research and highlights the energy savings potential in all climate​​ regions across the country.
