Firestone Building Products Launches Enverge(TM) Cavity Wall Products for Maximum Building Envelope Design and Performance

Continuous Insulation, Air & Vapor Barrier and Thru-Wall Flashing Improve Thermal Performance and Prevent Thermal Bridging

INDIANAPOLIS, -- Firestone Building Products Company, LLC, a leading manufacturer and supplier of a comprehensive "Roots to Rooftops" portfolio of products, introduced today the new line of Enverge(TM) Cavity Wall Products. The portfolio includes: continuous insulation (CI) exterior wall insulation (available in two facer options: coated fiberglass mat facer and aluminum foil facer), air & vapor barrier and thru-wall flashing. These individual products work together to improve thermal performance and prevent thermal bridging in commercial buildings.

"At Firestone Building Products we are focused on innovating products that lend to superior building performance. The launch of the Enverge line highlights the importance of the compatibility of products used in building envelope design in order to reach peak energy efficiency," said Chris Tobias, cavity wall business development manager at Firestone Building Products.  "This line, combined with our compatibility warranty, guarantees the integrity of the assembly of materials will not be compromised while in contact with one another.

"The Enverge portfolio benefits everyone from the architect to the contractor to the owner. From flexible building envelope design to installation ease, dimensional stability to significant energy savings, this system works harder to help a building achieve peak performance," concluded Tobias.

Features of the Enverge Cavity Wall Family of Products include:

Enverge Cavity Wall Products are covered by the Enverge(TM) Building Envelope Assembly Compatibility Warranty.

"The Enverge line was developed specifically in response to advancements in building requirements. According to ASHRAE 90.1-2007, continuous insulation is required in order to stop thermal bridging and help improve thermal performance of the wall assembly," said Cliff Black, building envelope product manager at Firestone Building Products. "We are committed to developing products and systems that contribute to high performance buildings and sustainable building practices. CI is currently the best option for insulating the building envelope in order to maximize performance and achieve long term energy savings."
