Every Owens Corning shingle line features:

Fiberglas® mat that adds weather protection, greater fire resistance and longer life.
Weathering-grade asphalt that holds the granules on the shingle and protects the roof from water.
Colorful mineral granules that help reflect the sun's rays while adding beauty and style to the roof.
Heat-activated adhesive strip that bonds shingles into a single, watertight unit.
Class A Fire Rating, the highest available for residential applications.
Wind Resistance Rating for winds and gusts up to 60 mph.
Limited product warranties ranging from 20 to 40 years, depending on shingle style.

Three-tab shingles are the roofing industry's standard, consisting of two layers of asphalt around a Fiberglas® mat core covered with ceramic mineral granules, notched into three integrated pieces, or tabs.
