Our NEW line of Thermally Broken WinDows and soon to be Door products are designed to be impact or non-impact. These are a great products for a historical restoration or a new development or even retro-fit projects.

Our Thermally Broken Aluminum WinDows are attractive, energy-efficient, and reliable.  The most important consideration in selecting a good WinDow is its thermal efficiency, its ability to minimize heat loss from the inside or heat gain from the outside. Today, our Thermally Broken Aluminum WinDows & Doors are manufactured with 3-composed pieces: an outer and inner extruded frame. The center central I-Strut core acts as a barrier to heat flow from a warm interior to a cold exterior in winter and vice-versa in summer. This construction creates a highly thermally efficient frame, and enables our products to take advantage of other important aluminum properties such as… durability, strength, stability and corrosion resistance.

 

What is considered a thermally broken aluminum window frame?

To be classified as thermally broken, a window must conform to the following definition by the U.S. National Fenestration Rating Council (ref: NFRC 100-2001).

"Thermal break: a material of low thermal conductivity that is inserted between members of high conductivity in order to reduce heat transfer.
