The Pressure Treatment Process
Our Pressure Impregnation Fire Retardation Treatment System begins as the cedar shakes and shingles are loaded into our pressure autoclave cylinder. All air and moisture is removed from the wood by a vacuum, at which point the fire retardant is pumped into the cylinder to thoroughly saturate the wood. Finally, the cedar shakes and shingles are transferred to our kiln where they are slowly cured for several days, forming a strong bond between the wood and fire retardant.
Depending on your preferences or the requirements of your local building code, you can select Class A, B, or C fire retardation, each with varying levels of fire protection.
Class A Fire Retardation
For fire protection in areas that are subject to severe fire exposure, our Class A Fire Retardant Treatment uses shingles treated with Class B Fire Retardant combined with a fire retardant cap sheet underlay. This treatment adds a high degree of fire protection to your cedar roofing. It won’t slip from position or pose a flying-brand hazard.
Class B Fire Retardation
Effective against moderate fire exposure, our Class B Fire Retardant Treatment ensures your cedar roofing is not easily flammable. This treatment provides moderate fire protection, prevents slippage and does not pose a flying-brand hazard.
Class C Fire Retardation
Suitable for homes in areas that have minimal fire exposure, our Class C Fire Retardant Treatment ensures your cedar roofing and siding is not readily flammable. With this treatment, your roof is not in danger of slippage and there is no flying-brand hazard.
