Vycor enV-S

What it is: Vycor enV-S

Why we like it: For many years, contractors used housewrap to keep air and water out of a building. Today, there are more options, including Vycor enV-S from Grace. This acrylic membrane creates a continuous barrier against water and air intrusion. It’s also vapor permeable, which allows the walls to breathe, preventing moisture from being trapped in the cavity. grace.com
