Energy Saving Products

Owens Corning’s commitment to sustainability starts with energy-saving and durable products.

Fiberglass Insulation

Fiberglass insulation, first commercialized by Owens Corning in the 1930s, is the most widely used type of insulation in the United States, Canada and Mexico today.

A typical pound of insulation saves 12 times as much energy in its first year in place as the energy used to produce it. That means the energy consumed during manufacturing is saved during the first 4-5 weeks of product use. The insulation continues to save that amount of energy every month throughout the life of the home or building in which it is installed.

Other fiberglass insulation products provide energy-saving thermal protection for HVAC, mechanical and commercial applications.

Extruded Polystyrene Insulation (XPS)

Our FOAMULAR® extruded polystyrene (XPS) insulation, a rigid board, is used on exterior and interior walls, foundations, roofs and infrastructure for thermal insulation even in wet conditions. It is reusable, with a proven history of removal, salvage and reuse.

Mineral Wool Insulation

Thermafiber® insulation was acquired by Owens Corning in 2013 to complement our portfolio of energy-saving products. Thermafiber® is used in commercial and residential buildings and can also deliver fire containment with its high temperature durability.


Our wide color range of “cool roof” shingles use a highly reflective granule technology that bounces back the sun's rays, helping keep roofs cooler and reduce air conditioning energy levels. They meet ENERGY STAR® requirements for solar reflectance of .25, the fraction of solar energy reflected by the roof.


Fiberglass-reinforced composites can be light, insulating and corrosion-, impact- and heat-resistant, and are used to replace steel, aluminum, wood and other materials. Fiberglass as a reinforcement provides for lighter weight while delivering comparable or better strength than other materials such as steel. Lighter weight means more fuel efficiency in all forms of transportation. With increasingly higher strength technology, composites have also provided more efficiency and greater economy for wind energy turbines using longer, lighter and more productive blades at lower wind speeds.

Glass fiber composites also have been shown to have less impact on the environment through comparison of the life cycle assessment of specific parts made from steel and aluminum. Life cycle assessment takes into consideration the raw materials extraction, manufacturing, installation, maintenance and end of life of composite parts vs. other materials.
