GAF Materials Corp., Wayne, N.J., introduces Camelot Premium Designer Shingles, available in Spring 2004. The new shingles feature GAF's Super-Heavyweight "Plus" construction (approximately 460 pounds per square) for ultimate durability. A special double row of Dura Grip adhesive seals each shingle tightly and reduces the risk of blow-offs, and the custom-specified, high-performance Micro Weave core provides better protection layer for layer. The shingles are warranted to withstand winds up to 110 mph. Their 17-inch by 34 1/2-inch size and larger 7.5-inch exposure means less installation time and cost. The shingles are Class A fire-rated and also come with Algae Eater protection from unsightly blue-green algae. Camelot shingles have a limited lifetime warranty with Smart Choice protection for the first 10 years, and carry a limited lifetime transferable warranty on both residential and commercial applications.
