Roofing

Its main roofing products are laminate asphalt roofing shingles, along with roofing components, composite lumber and oxidized asphalt, used mainly in residential construction. It sells shingles mostly through distributors, home centers and lumberyards in the United States. It processes its own asphalt for its shingles and sells processed asphalt to other shingle makers, roofing contractors and other industries, and it makes the glass nonwoven mat used in its shingles, which it also sells for vinyl flooring, gypsum wall boards, ceiling tiles and battery separators. The company states that, according to industry reports and its own estimates, it is the second largest producer of asphalt roofing shingles in the United States. Demand comes from repair and remodeling and new residential construction, and major storms can raise it sharply.

Insulation

Its residential insulation in North America includes thermal and acoustical batts, loosefill and spray foam insulation and foam sheathing, sold under names including Owens Corning PINK Next Gen FIBERGLAS Insulation. For non-residential markets it makes glass fiber pipe insulation, flexible duct media, stone wool insulation, cellular glass insulation and foam insulation, sold under brands including FOAMULAR, FOAMGLAS and Paroc. It sells in the United States, Canada, Europe and Latin America through retail, contractor and distribution channels, and demand for residential insulation in North America typically follows housing starts with a three-month lag. In 1956 it began using the color PINK, which made it the first owner of a single color trademark registration in the U.S.

Doors

It makes residential interior and exterior doors of wood, glass, fiberglass and metal, door components such as frames, sills, hinges and locks, and aluminum-framed glass doors and windows for luxury homes.
