WHY THE SANCTUARY TWO-HOUR FIREWALL IS SUPERIOR
Originally rated by Underwriters Laboratory in 2002, the SANCTUARY® Two-Hour Firewall uses Greenfiber® FRM spray-applied cellulose insulation for a defect-free installation, currently available in select markets.
Streamlined Installation
Because Greenfiber FRM insulation is blown in after the roof goes up, conventional framing is possible. That means, in addition to being protected from the elements, the SANCTUARY Two-Hour Firewall allows all trades to work simultaneously, which normalizes the sequence of construction.
Improved Compliance
To meet stringent energy efficiency codes, the SANCTUARY Two-Hour Firewall utilizes spray-applied Greenfiber FRM Insulation that completely fills gaps, voids and hard-to-reach places, reducing unintended airflow. This lowers the air changes per hour, eliminating customer callbacks.
Enhanced Comfort for Homeowners
Because the SANCTUARY Two-Hour Firewall fills gaps so completely, sounds and odors are blocked between neighboring units. Homeowners have much more control over their own indoor air quality, which allows them to live more comfortably.
