Thermal Barrier Protection Technology
The key component of Aluminum Shapes, LLC barrier protection technology is the Azon structural thermoset polyurethane break material used in our pour and debridge system. This thermal break material provides a much lower thermal conductivity rate, much higher shear strength rate, greater flexural strength, and higher processing throughput ratio versus polyamide strip systems.
Azon Features and Benefits
- Cost efficient
- Fast and simple to produce at 197’ per minute production rate
- One aluminum extrusion, single polymer cavity
- Slim sightlines to increase day lighting, improve energy savings, and enhance interior spaces
- Lower thermal conductivity, 0.84 Btu-in /(hr-°F-ft)
- Lower U-value at 2.25” = 0.39 Btu/(hr-°F-ft2)
- Structural properties – higher loading and greater spans compared to polyamide strip system
- Bendable, radius possible to 1.5”
How the Azon Pour and Debridge Process Works
Step 1 – Design
An aluminum window profile is designed and extruded with a strategically placed channel to encapsulate the Azon thermal break material. The channel surface is conditioned by abrading the profile to mechanically lock the polyurethane polymer with the finished surface of the aluminum profile.
Step 2 – Pour
Azon two component polyurethane thermal break material 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 removal of the metal bridge via sawing from the bottom of the channel produces a true, non metal-to-metal structural thermal barrier that is suitable for withstanding the most demanding climates and conditions with higher performance in impact resistance, shear strength, and heat distortion than alternative methods.
