MikronWood® Energy-Efficient Composite

MikronWood® Energy-Efficient Composite offers the aesthetic appeal of real wood with the outstanding thermal performance of a wood composite, providing window and door manufacturers a unique material to stand above the competition.

MikronWood is a solid-core blend of thermoplastic alloy resins that includes both polyvinyl chloride (PVC) and acrylic-based polymers. This unique vinyl window material combination does not absorb moisture, eliminating the threat from rot, mold and insects. MikronWood is highly stable, ideal for cold, high-heat and high-humidity climates—providing improved thermal performance over other frame materials, including aluminum, fiberglass and wood. These properties make it an ideal material to be used in window and door systems for new construction and replacement applications throughout North America.

Unlike wood, MikronWood will never rot, swell, split or require surface refinishing. Compared to aluminum, MikronWood composite won`t corrode or pit, while providing better thermal insulation properties. The National Fenestration Rating Council and independent labs confirm that MikronWood has a K-value that is 63% lower than pine, 83% lower than fiberglass and 69% lower than PVC.
