XO Windows is Proud to Now Offer The MI EnergyCore™ Window System

The MI EnergyCore™ Energy Efficient Window System is designed for optimal energy efficiency and high performance without compromising style and functionality. This R-5 insulating window system is a high performance energy efficient window system, derived from a combination of patented AirCell™ PVC frame technology, TMAX™ Insulating Glass, and a design that incorporates numerous physical barriers against air and water infiltration.

The frame is manufactured with a patented AirCell PVC material that is co-extruded and thermally bonded. This creates a fully insulated, corner welded frame that results in superior energy efficiency and strength. The frame is designed to support triple pane insulating glass to maximum residential sizes in any style. Additional strength is achieved thru internal aluminum reinforcements at the lock rails for maximum security.

Numerous air and water barriers are engineered into the panel and frame interface. These barriers include multiple contact points of weather stripping and/or compression bulbs, interlocking meeting rails, and a pocketed sill with a sloped drainage path. These features are designed to keep a home’s interior dry even in harsh conditions. All styles of the MI EnergyCore Series including the r5 insulating window have been tested to an AAMA Performance Grade 40 or above.

The MI EnergyCore Window System achieves optimal energy efficiency. The frame blocks thermal conductivity at least 6 times better than fiberglass, 4 times better than rigid PVC, and 3 times better than wood.

When we combine the MI EnergyCore frame with our high-performance, triple-pane, argon-filled TMAX glass packs, the resulting window exceeds ENERGY STAR® requirements by 30 – 50 percent and meets the requirements for the Department of Energy’s R-5 High Performance Windows Program.
