Tests preformed to qualify the retardancy of treated
cedar shakes and shingles
Before any organization can offer fire retardant
roofing material and make claims to levels of fire
retardant certifications (Class A, B, or C), the product
must pass a variety of 1-year, 2-year, 3-year, 5-year,
and 10-year real weathering and burn testing.
Tests
must be conducted by an independent and recognized
third party laboratory.
As well, each month samples are randomly collected from
our treatment facility. Every three months, test decks
are tested to maintain these classifications.
Fire Smart Roofing Treatment also enlists the services of QAI
Auditing & Laboratories Inc. (BC) and Forinteck
Laboratories (Los Angeles) to periodically maintain
our standard of classifications.
FSR Treatment Inc.'s treated cedar shakes and shingles are subject
to nine separate burn tests to evaluate to performance of our treatment process.
These tests include:

Accelerated Weathering Testing
Each
of our Class A, B, and C treated cedar shakes and shingles
have passed accelerated 10-year weathering tests to ensure
the longevity of our fire treatment process.
The ICBO accelerated weathering tests are
designed to simulate the exposure and surface erosion
experienced by any roofing product exposed to the outdoors
over a long period of time. To properly simulate such
a long period of exposure, scientists developed a system
that bombards the roofing materials with such an intense
level of:
- ultraviolet radiation
- exposure to high pressure water
- intense freezing / heating cycles
|
for thousand of combined hours of testing. When
the products facing simulations were compared to products
that had been weathered in real life situations, the
erosion was identical if not worse.
In order for FSR
Treatment to complete the certifications of ASTM, ICBO,
UBC, our products were subjected to these simulations
by recognized third party laboratories, after which
the products were resubmitted to the nine methods of
burn tests outlined above.
Real Weathering Testing
Fire Smart Roofing Treatment has passed ICBO requirements for
the one, two, three, and five-year real time natural weathering
tests. For each test, products were placed outdoors
and exposed to the elements for each of the required time
periods and then tested with all of the intermittent flame,
burning brand, multiple burning brand, and flying burning
brand tests outlined by UL.
FSR is now involved with an ongoing 10-year real time natural weathering test.
This ICBO real life test is designed to eliminate any doubt, by even the most
skeptical of individuals of the longevity of fire retardant from the pressure
impregnation treatment process. |
