[16] [17] The color PINK was trademarked through Owens-Corning in 1986, making it the first company to trademark a color. By 1990, Owens-Corning was the defendant in about 84,500 asbestos-related lawsuits.
An asphalt shingle roof has flexible asphalt shingles as the ridge cap. Some roof shingles are non-combustible or have a better fire rating than others which influence their use, some building codes do not allow the use of shingles with less than a class-A fire rating to be used on some types of buildings. Due to increased fire hazard, wood ...
The length of time required for a penetrant or sample on average to exceed a specified average heat rise above ambient at any single location determines the duration for the FT Rating (Fire and Temperature). If a hose-stream test is passed afterwards, the rating can then be expressed as an FTH Rating (Fire, Temperature and Hose-stream). The ...
Today shingles are mostly made by being cut which distinguishes them from shakes, which are made by being split out of a bolt. Wooden shingle roofs were prevalent in the North American colonies (for example in the Cape-Cod-style house), while in central and southern Europe at the same time, thatch, slate and tile were the prevalent roofing ...

The output section of the NFDRS structure chart is the components or simply the outputs that are based in fire behavior description but expressed in the broader context of fire danger rating. [6] Spread Component – Displays a value numerically equivalent to the predicted forward rate of spread of a head fire in feet per minute.
Durometer, like many other hardness tests, measures the depth of an indentation in the material created by a given force on a standardized presser foot. This depth is dependent on the hardness of the material, its viscoelastic properties, the shape of the presser foot, and the duration of the test. ASTM D2240 durometers allow for a measurement ...
Solar shingles are photovoltaic modules, capturing sunlight and transforming it into electricity. Most solar shingles are 12 in × 86 in (300 mm × 2,180 mm) and can be stapled directly to the roofing cloth. When applied they have a 5 in × 86 in (130 mm × 2,180 mm) strip of exposed surface.
