Thermally Broken WinDows and Doors
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.

Thermal break technology may not be familiar for all of you...
The idea is to separate an aluminum window or door profile to reduce thermal conductivity from the outside to the inside. There are a few ways to do this, one is called pour & de-bridge which is not a true method of thermal break as it leaves aluminum touching at several points along a profile extrusion thus still allowing heat and cold transfer. The other method which is more prominent among high-end manufacturers such as WinDoor Incorporated is the use of Iso-Bars (also called I-Strut). This I-Strutr method is the most structurally sound and thermally beneficial method of thermally breaking aluminum. The I-Strut is made using a polyamide material with glass fibers integrated to provide maximum strength. The polyamide I-Strut provides around 500 times less thermal conductivity than aluminum thus making the system perform to superior energy standards. The use of high performance glass that WinDoor Incorporated can supply makes an aluminum Door or WinDow the perfect choice.
