Enhancing our pour-and-debridge thermal improvement services, Linetec has added an Azon Lancer™ to provide mechanical surface conditioning of the aluminum extrusion cavity to ensure maximum adhesion of the thermal barrier polymer to durable, architectural finishes.
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.
The channel’s surface is conditioned using the Lancer to pierce the surface creating lanced, inward curving aluminum lug projections in a staggered formation along the extrusion cavity. This mechanically locks 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.
As an approved Azo-Brader and Lancer Applicator, Linetec follows the guidelines set forth in the Azon “Quality Assurance Guide” and AAMA QAG-1-09, “Quality Assurance Processing Guide for Pour and Debridged Polyurethane Thermal Barriers.”
Aluminum extrusions that receive mechanical surface conditioning from Linetec using either the Azo-Brader or the Lancer are supported with a 10-year warranty.
