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.

Technoform thermal barrier system installed at Houghton Academy


Buffalo Public School #69 – Houghton Academy

Linetec, Wausau Window and Wall Systems and Technoform Bautec North America, Inc., contribute to the updated appearance and enhanced performance of historic Houghton Academy in Buffalo, N.Y. Along with refreshed façade, the elementary school’s modern windows feature Technoform Bautec’s polyamide thermal barrier for energy efficiency, structural performance and long-term durability.

Glazing contractor T.G.R. Enterprises replaced 125 of the building’s outdated windows with Wausau Window and Wall Systems’ high-performance units. These windows were finished by Linetec and customized to match the elementary school’s architectural aesthetic using a Sandstone color paint on the exterior and a Dark Bronze anodize on the interior.

Constructed in 1924, Buffalo Public School #69 Houghton Academy was designed by the Associated Buffalo Architects Inc. The U-shaped floor plan surrounds a courtyard in the rear and a Classic Revival style entrance in the front. The brick and stone structure is punctuated with large window bays. As time passed, the windows were replaced without preserving the architectural integrity. This resulted in inconsistent window types, trim and colors.

HoughtonAcademy-inerior-technoform-bautec“Choosing different color schemes and finish types for the interior and exterior of a high-performance aluminum window system can be achieved within budget and on accelerated timelines,” says Chad Ricker with Technoform Bautec’s market team. “Because two different finishing types were used on Houghton Academy windows — paint and anodize, any other thermal barrier method would not have been an option for this project.”

To ensure a successful result, the glazing team relied on Wausau’s 310i Series single-hung and 4250i-XLT INvent™ Series project-out windows. Both are manufactured using Technoform Bautec’s polyamide thermal barriers, known generically as “thermal strip.”

For two-color frame finishing using paint at the interior and exterior, Linetec estimates that Technoform Bautec’s thermal strip system painted assemblies are 400% less expensive than other thermal barrier methods that require time-consuming masking. read more
