Western Extrusions Corporation has been meeting customers’ demands for quality aluminum extrusions since 1979. Beyond the extrusion process, the company has the ability to fabricate extrusions up to 55 feet in length to customers’ specifications using state of the art CNC equipment.
Aluminum extrusions are the most common frames around which commercial windows are built. With energy conservation an ever-growing concern, every effort is made to come up with new ways to produce windows that experience as little energy loss as possible. As aluminum is a good thermal conductor, if the aluminum in a window frame is continuous from the exterior surface to the interior surface, this energy transfer through the metal represents a major thermal loss. A solution to this problem is to create a break in the form of a thermal barrier between the aluminum on the inside of the window and the aluminum on the outside.

Western Extrusions regularly works with engineers to solve this problem by creating what is known as a pour and debridge extrusion. An extrusion is engineered in which a cavity running the length of the extrusion is later filled (poured) with an insulating polyurethane foam, which when cured becomes a structural element of the window. Aluminum on both sides of this structural foam is then machined away (debridged), creating the desired thermal break between the aluminum elements on the interior and exterior. This thermal break is responsible for a significant improvement in the thermal efficiency of the window. Read Less
