http://firestonebpco.com

Firestone Building Products’ Enverge Air and Vapor Barrier is an asphalt-based, self-sealing wall barrier that provides energy savings and contributes to better air quality for building occupants. According to the manufacturer, this system offers the following advantages:

• Reflective facer provides energy savings
• Self-sealing barrier
• Consistent membrane thickness
• Minimizes drafts and reduces moisture to guard against mold
• Meets or exceeds ASTM D5602, D1876, D903, E283, E96, and E330.

Installation considerations include:

• Surface must be primed with an Enverge primer
• Remove the release liner at a 45° angle in 3” increments to promote correct alignment and installation continuity
• The membrane should be firmly rolled from the center to the outside for maximum adhesion
• Seams should overlap a minimum of 2” for effective coverage
• Self-seals around mechanical fasteners and minimizes air leakage around open gaps; foil flashing tape can also be used to seal penetrations.
