Roof Fire Ratings
Our roof materials carry a “Class C” designation for the CAN/ULC S107 (2010) Methods of Fire Tests of Roof Coverings and ASTM E108 (2011) Standard Test Methods For Fire Tests of Roof Coverings.
In the first quarter of 2014, an independent testing agency ran tests on Shelter Works roof materials, proving our “Class C” designation. The series of tests included these three:
SPREAD OF FLAME TEST
Measures how quickly the fire spreads when a fan blows a flame onto the roof material for a sustained amount of time.
INTERMITTENT FLAME TEST
Exposes the flame to the roof material on an intermittent basis, exposing it, then stopping, then exposing it, then stopping.
BURNING BRAND TEST
Puts a combustible material on top of the roof and exposes it to wind to see what difference that makes on the roof.
