Are Organic Shingles Bad?
Not necessarily. However, the quality of raw materials used to produce organic mat has diminished since the introduction of organic shingles: cotton rag has been replaced primarily by waste paper formulas or even sawdust! Additionally, either over- or under-saturating organic mat can result in problems. The use of modem fiberglass technology reduces these manufacturing sensitivities and risks.
Organic Mats...
-
Are made primarily of waste paper (cardboard, newspaper), wood fiber and other "by-products"
-
Contain trace contaminants such as aluminum foil, plastic, and styrene foam that can cause voids
-
Can exhibit variation in content and consistency from one production run to the next.
Typical organic shingles spread fire up to 600% farther and faster than fiberglass shingles in the Underwriters Laboratories tests.
