IMPROVING PERFORMANCE
WITH THERMAL BARRIER
SYSTEMS.

THERMAL POUR & DEBRIDGE

Using a thermal barrier system improves performance by separating the aluminum profile into two parts, while maintaining the structural and long-term durability of the unit. Aluminum is a highly thermal conductive material that will rapidly transfer exterior climatic temperature unless something is done to stop the thermal conduction.

A thermal barrier system will improve thermal performance while maintaining the structural and long-term durability of the fenestration unit. Azon thermal pour and debridge offers tremendous performance, protecting against temperatures of -100C (-148F). Neither extreme cold or hot temperatures will transfer through an aluminum frame with pour and debridge thermal barrier.

When your building demands structural longevity and windload protection

The pour and debridge method is suitable for withstanding the most demanding climates and conditions with the highest performance in impact resistance, sheer strength and heat distortion. When considering structural longevity, wind loads in high rise buildings and in curtain wall applications, composite materials that perform both efficiently and structurally are demanded. Thermal barriers are true structural insulators that maintain an extremely high shear modulus for windloads. Azon’s polyurethane’s pour and debridge systems are formulated for these exacting applications.

As an approved applicator, Linetec and Azon follow the guidelines set forth in the AAMA QAG-1-98 specification, Quality Assurance Processing Guide for Pour and Debridged Polyurethane Thermal Barriers.

THREE-STEP POUR & DEBRIDGE PROCESS


The three-step pour and debridge process, which includes a mechanical lock by either the Azo-Brader or Lancer method, results in an energy-saving window frame with the advantage of long-term durability that is warranted from structural deterioration.

TWO-PART POLYURETHANE


Pour-and-debridge thermal barrier systems use a two-part polyurethane that is poured into and cured within a “dog bone” structural cavity in the finished aluminum extrusion, after the cavity surface is conditioned using either the Azo-Brader or the Lancer machinery, to limit the bridge of metal that acts as a conductor of hot or cold temperatures on the exposed surface.

THE AZO-BRADER™


The Azo-Brader™ abrades the profile utilizing a carbide tool insert that reciprocates vertically to create raised projections on the thermal barrier pocket. The action of the tool is such that the aluminum is actually displaced under high velocity.

The Azon Lancer™


The Azon Lancer™ provides a unique method of punching the profile material to produce inward curving lanced indentations along the lugs in the pour cavity in such a way as to produce a structural mechanical lock. The Lancer also enhances the shear strength of the resulting polymer and aluminum composite..

The Azo-Brader and the Lancer mechanically lock the polyurethane polymer with the finished surface of the aluminum profile to ensure significantly improved adhesion. After the polyurethane has been poured into the cavity and solidified, the metal bridge from the bottom of the channel is removed to produce a true, non-metal-to-metal structural thermal barrier.

MATERIAL SIZE & CAVITY GUIDELINES

  • Extrusions must be 6′ or longer to be debridged
  • Radius material can be poured by Linetec, but not easily debridged
  • Thermal fill cavity must be symmetrical to be abraded
  • The opening of the fill cavity must be obstruction-free for the profile to be abraded
  • There must be at least 1/8″ clearance beyond each of the lugs for the profile to be abraded
  • Lance must be open from the top
  • Side walls must be .80 and able to be supported from a lower support wheel
  • Top wall must be at max .065
