Thermal Barrier

The window frame is extruded with a thermal barrier channel. There is an optional process that is recommended for extrusions that are to be anodized.  This requires a portion of the thermal break pocket be abraded to produce a mechanical bond with the polyurethane polymer in fill material.

The frame member is then finished by either painting or anodizing.  A specially formulated, two-part liquid polyurethane is poured into the thermal barrier channel where it rapidly solidifies to become a very strong and highly durable bonding polymer.

Finally, the frame is passed over a cutting machine to remove part of the channel and "debridge" the window, separating the interior of the frame from the exterior of the frame.

Adding strength to the process in special cases where greater structural integrity is required, "skip debridging" makes it happen.  The process removes a specific amount of the aluminum web in an interrupted pattern that enhances the strength of the frame while providing the thermal break. The result is a very strong, durable and highly efficient thermal insulated barrier.
