Owens Corning Fiberglas™ insulation represents the global standard in glass wool technology, engineered for superior thermal control, acoustic attenuation, and fire resistance in residential, commercial, and industrial applications. As a certified Material Innovation Certificate (MIC) holder, Owens Corning delivers consistent, high-performance insulation solutions backed by over 80 years of material science leadership.
Owens Corning Fiberglas™ insulation is manufactured using advanced centrifugal fiberization technology that converts sand and recycled glass into fine, uniform glass fibers. The proprietary EcoTouch™ binder system represents a breakthrough in sustainable insulation chemistry, replacing traditional phenol-formaldehyde binders with a bio-based formulation that reduces embodied energy while maintaining structural integrity and performance. The manufacturing process incorporates a minimum of 50% post-consumer recycled glass content, contributing to circular economy objectives and green building certification credits including LEED v4.
Fiberglas™ insulation achieves low thermal conductivity values ranging from 0.033 to 0.040 W/(m·K) depending on density and application, delivering reliable thermal resistance (R-value) across the service life of the building. The open fibrous structure creates millions of microscopic air pockets that impede heat transfer through conduction and convection. Unlike foam plastics that can lose R-value as blowing agents diffuse over time, Fiberglas™ insulation maintains its thermal performance indefinitely as long as the material remains dry and uncompressed. The stable fiber matrix ensures dimensional integrity, preventing settling or slumping that could create thermal bypasses.
Available in densities from 8 kg/m³ to 100 kg/m³, the product range accommodates applications from cavity wall insulation to high-density board stock for HVAC equipment and industrial processes. The unfaced configuration delivers thermal performance without vapor retarder properties, while kraft-faced and foil-faced options provide integrated vapor control for specific climate zones and applications.
