Book Description
Numerous fire-retardant systems were evaluated for fire performance and durability on western red-cedar shingles. Methods of evaluation appeared severe enough to screen the less effective methods. (Author).

Book Description
Some building codes require wood shingles to be fire-retardant treated. Because exterior fire-retardant treatments are subjected to weathering, treatment durability and leach resistance are critical for insuring adequate fire protection. We examined the effectiveness of various fire-retardant treatments on wood after 0, 2, 5, and 10 years of outdoor exposure. We used a Class C burning-brand test (ASTM E 108) and a Schlyter flamespread test to evaluate effectiveness. Most shingle treatments evaluated were either pressure impregnated or coated at the Forest Products Laboratory; however, a commercial treatment was used as a control. After 10 years of exposure, most treatments passed the Class C burning-brand test, but lost considerable effectiveness in the Schlyter test method. The commercial treatment was the most effective after 10 years of weathering.

Book Description
As a part of a continuation study on fire-retardant treatments for wood shingles and shakes, shingles were treated by systems selected from previous research, including commercially treated class C shingles, and exposed outdoors for 2, 5 and 10 years. This is a progress report after 5 years' exposure and fire testing by burning brand and modified Schylter tests. Generally acceptable results were obtained after 2 years' exposure, except for a reference pyresote treatment. After 5 years' exposure, all systems passed 80 percent or more of the burning brand tests except for the pyresote and the pyresote with light sealer coating. All systems showed weakness in the Schlyter, but in four of the eight systems flames on shingles were self-extinguishing. (Author)

Book Description
The availability of western red cedar has decreased in recent years, and other species of wood are being considered as substitute materials for wood shakes and shingles. However, the wood of these alternative species is more susceptible to decay than is western red cedar. The objective of this study was to evaluate the fire performance of combined fire retardant and preservative treatments using different fire test methods. Several amino resin fire retardants were used in combination with several wood preservative compounds that imparted both fire retardancy and decay resistance to wood. Treated specimens underwent fire tube tests and based on the results of these tests, two fire retardants and two quaternary ammonium preservatives were selected for additional fire testing. These treated materials were subjected to a modified Schlyter test and a burning brand test. The heat release rate was also measured. Both weathered and unweathered specimens were evaluated. The unweathered and weathered treated material exhibited good fire performance.
