R-CORE® INSULATION
FOR HIGH THERMAL PERFORMANCE
Tests prove that the vinyl used in the construction of Ply Gem windows provides higher thermal performance than windows made of wood or metal.
But we don't stop there. In addition to our thermally superior vinyl, Ply Gem window mainframes are filled with patented R-Core® (pre-expanded high-density solid-polyurethane insulation). The same type used in many refrigerator/freezer doors.
Our window frame design is so energy efficient that interior frost and condensation are virtually eliminated. That means no more stained paint or drapes, plus increased comfort, and reduced utility bills.
INTERCEPT™ PLUS GLASS SYSTEM —
A MAJOR ADVANTAGE
All insulating glass will save energy. However, the Intercept™ Plus system is true warm perimeter technology. This advanced insulated glass spacer system utilizes a unique U-shaped channel to separate glass panes and interrupt the natural flow of heat to cold and is standard on most products. Intercept reduces the thermal transfer around the glass perimeter that can cause condensation and puddling.
While most spacer systems use four separate pieces of aluminum joined together by corner keys, our Intercept™ warm-edge design is one continuous piece. The result is a stronger, more energy-efficient insulated glass unit. In addition, Intercept spacer's unique ability to flex with glass expansion and contraction ensures a strong seal for the life of the window.
Hi R+Plus® GLASS FOR REDUCED CONDENSATION
With Hi R+Plus, your windows stay warmer to the touch... so the comfort level of your home is increased. Closely related to this increased comfort is the fact that window condensation is virtually eliminated. In short, you'll be able to maintain higher levels of interior humidity — a variable that increases your level of comfort and reduces your utility bills.
