Our composite reinforcement is lighter than aluminum, stronger pound per pound than structural steel and thermally compatible with vinyl extrusions.
In the meeting rails of every Xtreme Window, it not only adds to the window’s thermal efficiency, but also gives the window added strength where it’s needed the most.
The lock and keeper screws are anchored into this heavy-duty composite, not just into vinyl rails.
Foam-filled Sash & Frame
Xtreme Windows have the highest energy ratings due to our extensive glass packages, but also because we insulate our sash and frame members. By filling selected cavities of each part of the frame and sash with foam, we enhance the thermal efficiency of the window compared to windows with only hollow cavities.
Foam enhancement gives our product higher energy ratings. This translates into greater savings on your heating and cooling bills.
