MikronWood® Thermal Advantage Window System


MikronWood® Thermal Advantage Window System features our revolutionary MikronWood composite frame material for increased thermal performance. The solid-core material is a blend of thermoplastic alloy resins that includes both polyvinyl chloride (PVC) and acrylic-based polymers. This unique resin combination doesn`t absorb moisture, relieving homeowners from damage caused by rot, mold and insects.

MikronWood is a highly stable material that`s ideal in cold, high-heat and high-humidity climates – providing significantly improved thermal performance over other frame materials, including hollow PVC, aluminum, fiberglass and wood. Additionally, current manufacturers and installers enjoy MikronWood`s solid construction that saws and mills very similar to wood with no need for costly diamond-tipped blades, pre-drilling, corner keys, caulking and cleanup.

The MikronWood Thermal Advantage Window System is designed for both the replacement and new construction market. It features a 4-1/2 inch frame depth that accommodates up to 1-3/8 inch thick insulating glass – perfect for highly efficient triple-glazed glass units. With an emphasis on visual appeal, thermal performance and low maintenance, this system is tailored to energy efficiency and design conscious customers.
