Linetec enhances its pour and debridge services by adding Azon’s Lancer

Linetec Lancer materialEnhancing 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 LancerMachine2lanced, 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.

Thermal Improvement Services

The main function of a thermal break system is to separate an aluminum profile into two parts to reduce thermal conductivity in a window. The two ways of doing this are by using poured polyurethane or polyamide insulating strips.

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.

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.

Thermal Pour and Debridge

Thermal Pour and Debridge

Polyurethane’s pour and debridge systems are formulated for these exacting applications. Azon thermal pour and debridge offers tremendous performance, protecting against temperatures of -100C (-148F). Extreme cold, nor hot temperatures, will transfer through an aluminum frame with pour and debridge thermal barrier.

Thermal Strut involves two separate extrusions and joins them through the use of engineered structural plastic strut. Both the inside and outside aluminum profiles are extruded independently with a cavity that will ultimately receive the strut.

Thermal Strut Process

Thermal Strut Process

With Technoform thermal strut, products can be manufactured with two-tone finishes; because interior and exterior components can be coated before assembly. Architects and designers can choose to apply the interior and exterior finishes that best match their cost, performance and design requirements.

Thermal Strut offers increased energy savings with varying thermal separation widths.

A thermal barrier system will improve thermal performance while maintaining the structural and long-term durability of the fenestration unit. Customers that choose Linetec, can rely on our thermal barrier service to ensure optimal performance of the thermal barrier.
