ANSWER: Select the correct weather protection system.
Air and water barriers are an integral part of any residential building project. For many years, mechanically-attached house wraps were the standard, with very few alternatives.
GCP Applied Technologies, formerly Grace Construction Products, introduces VYCOR® enV-S™, a self-adhered weather resistive barrier that provides premium weather protection. It's an advanced alternative to house wraps.
The weather resistive barrier represents the latest in residential building science to create an air-tight, yet breathable home that achieves the highest product performance available.
Lab-tested, VYCOR® enV-S™ will protect your home, wallet and Mother Earth
Unlike mechanically-attached house wraps, VYCOR® enV-S™ seals to itself, seals around fasteners, and forms a strong adhesion with the substrate, even when exposed to harsh weather conditions. This eliminates costly rework. And, most importantly, VYCOR® enV-S™ improves the home's energy efficiency, leading to significant energy savings for the homeowner.
A recent study conducted by the Oak Ridge National Laboratory (ORNL) revealed that VYCOR® enV-S™ 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.
In the northernmost area of the U.S., for example, the savings were estimated at $669 annually (or 56.2% energy savings) for a typical home with VYCOR® enV-S™ compared to one with a traditional house wrap.

The enhanced energy efficiency, improved installation process and superior long-term weather protection of GCP’s VYCOR® enV-S™ weather resistive barrier make it the product of choice for quality homebuilding professionals. Right now, for a limited time, GCP is offering a rebate of up to $750 to builders in the United States, who purchase this product for the first time. VYCOR® enV-S™, a self-adhered weather resistive barrier, provides premium weather protection and energy savings as an advanced alternative to house wrap.
