Azon provides turnkey solutions to the extruder or window manufacturer with complete machinery, thermal barrier chemicals, quality control, design assistance and field service programs. How the pour and debridge process works is outlined below.

How the pour and debridge process works

step1 - mechanical lock

Step 1 – Design

An aluminum window profile is designed and extruded with a strategically placed channel to encapsulate the Azon insulating polymer.
The channel surface is conditioned by using one of two machinery devices that produce a mechanical lock to enhance the shear strength of the resulting polymer and aluminum composite.

  • The Azon Lancer™ is a mechanical device that works inline with pour and debridge processing.
  • The *patented Azon Azo-Brader™ abrades the profile pocket to mechanically lock the polyurethane polymer with the finished surface of the aluminum profile.

Step 2 – Pour

Employing the Azon Fillameter™ equipped with the Azon Tornado III™ dynamic mixer, two-component polyurethane is dispensed as a liquid into the thermal barrier channel. Within minutes, the thermal core solidifies into a very strong, structural polymer.




Step 3 – Debridge

The extrusion is transported to the Azon Bridgemill™ for the third step in the process—removal of the metal bridge from the bottom of the channel to produce a true, non-metal-to-metal structural thermal barrier. The pour and debridge method is suitable for withstanding the most demanding climates and conditions with higher performance in impact resistance, shear strength and heat distortion than alternative methods.
