How it Works

Creating A Structural Thermal Barrier

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 AZON machinery products to produce a mechanical lock to enhance the shear strength of the resulting polymer and aluminum composite.

MLP™ (Mechanical Lock Profile) is a structural thermal barrier cavity design with a larger cavity size which improves the energy efficiency of aluminum fenestration products. Intended for use in high performance building envelopes in the most demanding climates, MLP™ integrates design and processing technology for superior thermal performance and shear strength over other architectural fenestration technologies.

  • The AZON Lancer™ and the The AZON Azo-Brader™ provide mechanical surface conditioning of the extrusion cavity to ensure proper adhesion of the polyurethane polymer to difficult finishes.

Step 2 – Pour

The AZON Fillameter™ ensures two-component structural polymers are mixed properly and dispensed as a liquid into the thermal barrier channel. Within minutes, the thermal core solidifies into a very strong, structural polymer producing a thermal barrier

Step 3 – Debridge

Filled extrusions are transported to the AZON Bridgemill™ for the third step in the pour and debridge – removal of a metal bridge from the bottom of the channel to produce a true, non-metal-to-metal, structural thermal barrier. The result is a structural composite of aluminum and polymer which forms a high-performance thermal barrier with stronger impact resistance and shear strength than alternative methods for withstanding the most demanding climates.
