Thermal pour-and-debridge services enhance energy efficiency and comfort

Aric-Dave-3-2017-lowresContributing to commercial and residential properties’ energy efficiency goals, high thermal performance has become an expectation when selecting window, skylight, curtainwall, storefront and entrance systems. Polyurethane pour-and-debridge systems are formulated for these exacting applications and suitable for withstanding the most demanding climates and conditions with the highest performance in impact resistance, sheer strength and heat distortion.

At Linetec, we use a three-step pour-and-debridge process, which can include an Azo-Brader or Lancer method mechanical lock. When needed, we also offer skip debridging and double debridging services. Our process results in thermally improved aluminum frame that helps building owners save energy and keeps building occupants comfortable.

Building owners and architects do not need to compromise performance for aesthetics if they want a radius instead of a rectangle, We offer a full pour-and-debridge of radius material, both structural and non-structural. We have no restrictions on the degree of curvature in aluminum framing members, including 90-degree corners.

As always, our finishes may be specified in nearly any color of liquid paint, in decorative wood grain finishes, or in anodize including our no-patina copper or brushed stainless finishes.

Linetec now provide thermal improvement services for curved and radius, finished aluminum extrusions backed with an industry-leading warranty. Linetec’s new processes offer a full pour-and-debridge of radius material, both structural and non-structural, and a fully crimped thermal strut system. There are no restrictions to the degree of curvature, and finishes may be specified in liquid paint, powder coat or anodize.

Durable finishes, thermal comfort and energy performance can be combined with recycled aluminum content, daylight, views and other environmental benefits for recognition by such green building and design guidelines as the U.S. Green Building System’s LEED® certification.

Contributing to commercial and residential properties’ energy efficiency goals, high thermal performance has become an expectation when selecting window, skylight, curtainwall, storefront and entrance systems. Building owners and architects don’t need to compromise performance for aesthetics if they want a radius instead of a rectangle.

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. The two methods for doing this are pour-and-debridge or thermal strut systems. Linetec follows the stringent industry standards of AAMA QAG-2-12, “Voluntary Quality Assurance Processing Guide for Polyamide Thermal Barriers” and QAG-1-09, “Quality Assurance Processing Guide for Pour and Debridged Polyurethane Thermal Barriers.”

Rolled-TB-Extrusion-web2Installing the thermal barrier in the metal after it has been curved helps minimize stress on the thermal barrier and ensures performance as specified. Choosing the thermal strut system provides the additional design flexibility of dual finishing, where the interior and exterior surfaces may be finished in different colors and formulations.

Regardless of the effect the curving process has on the finish, nearly all manufacturer and applicator warranties are voided when extrusions or brake metal are finished prior to curving. When customers ship us their radius-strut-webaluminum, Linetec alleviates this worry and performs all the services in the proper order and the same place to retain the full finish warranty. Utilizing Linetec dedicated fleet of trucks, we also save customers shipping costs and transit time.

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.
