Class C& B- Fire Retardant
The safety of homeowners is of primary concern to the CSSB. Although no product is fire proof, Certi-Guard® pressure - impregnated fire retardant treated cedar shakes and shingles are available in Class A, B and C roofing systems for use in many areas where the building code requires flame-resistant roofing materials to be used. Please check with your local building official regarding regulations for your area.
Class "A" Fire Retardant Roofing System
This classification uses a Class "B" fire retardant treated product along with a UL (Underwriters Laboratories) rated fire retardant fiberglass cap sheet underlay. A Class "A" roofing system is effective against severe fire exposures. Under such exposures, roof coverings are:
- Not readily flammable
- Afford a fairly high degree of fire protection to the roof deck
- Do not slip from position
- Pose no flying brand hazard
|
Class "B" Fire Retardant Treatment
Class "B" fire retardant treatment is effective against moderate fire exposures. Under such exposures, roof coverings of this class are not readily flammable, afford a moderate degree of fire protection to the roof deck, do not slip from position and pose no flying-brand hazard.
Class "C" Fire Retardant Treatment
A product that is effective against light fire exposures. Under such exposures, roof coverings of this class are not readily flammable, afford a measurable degree of fire protection to the roof deck, do not slip from position and pose no flying-brand hazard.
The current recommendations by fire experts in forest/urban interface areas advise brush setbacks, firebreaks, and non-combustible or fire resistant building materials.
