Thermal strut supports energy efficiency, curves and corners, dual finishes

strut05-webAdding insulating, thermal, polyamide strut to aluminum framing members separates the inside and outside metal, which greatly enhances a window, door, skylight, storefront or curtainwall system’s thermal performance. This thermal break reduces the amount of heat transfer, therefore saving energy and increasing occupant comfort.

At Linetec, we offer a fully crimped thermal strut system. We have no restrictions on the degree of curvature in aluminum framing members. For corners, our 90-degree thermal strip process not only saves time and labor, but also minimizes inconsistencies and waste, holds customer-specified tolerances for U-Factor and shear testing, and delivers a high-quality finished product.

two-tone2-webOur thermal strut also presents a cost-effective opportunity for dual finishing options, where one finish type or color is used on the exterior and another on the interior. 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.

Thermal improvement matters for energy efficiency in both warm and cold climates

SHORE MEM INT NJModel Energy Codes adopted across the U.S. are directing buildings to achieve more efficient performance. Whether trying to keep the warmth inside in cold climates or trying to keep the heat outside in warm climates – Linetec helps optimize aluminum architectural manufacturers’ systems to meet thermal requirements in all climate zones.

Thermal Barriers

Linetec enhances the thermal performance of architectural metal products, such as window, skylight, curtainwall, storefront and entrance systems.

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. The two methods for doing this are:

While both methods achieve high thermal performance, thermal strut also simplifies dual finishing, where the interior and exterior surfaces may be finished in different colors and formulations.

Curves and Corners

Installing the thermal barrier in the metal after it has been formed helps minimize stress on the thermal barrier and ensures performance as specified.

Linetec performs all these services in the proper order, to industry-leading quality assurance standards, and in the same location to retain the full warranty.

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 adds 90-degree strut thermal improvement capabilities

90-degree thermal strut in a single step

90degree-strut-Schmidlapp-Close-Up-(3)Linetec is one of very few companies in North America to provide 90-degree thermal strip with a single pass using Technoform Bautec’s polyamide insulating strips and Müller Technologies AG’s knurling equipment to install the strip simultaneously on two planes of material,” explains Bart Hensley, sales engineer at Technoform Bautec.

The need for direct access from both sides has always been a design limitation of strip systems. This new capability frees up window and curtainwall designers to detail changes in place more efficiently, using a single assembly, rather than multiple pieces – without compromising energy efficiency or condensation resistance.

When installing thermal strip, Linetec follows the requirements of AAMA QAG-2-12, “Voluntary Quality Assurance Processing Guide for Polyamide Thermal Barriers.” First, the inside and outside aluminum profiles are finished in anodize, liquid paint or powder coating. Different colors and finishes may be used on each profile as the aluminum is extruded independently with a cavity that will receive the strip.

90degree-strut-extr              90degree-strut-equip

During the assembly process, knurling produces “teeth” in the aluminum pocket that “bite” into the strip and ensures appropriate shear strength of the composite profile. As material passes through the knurler, the strip is inserted into the extrusion cavity. The crimping process mechanically locks the aluminum and strip, forming the bond between the two extrusions and the strip.

Traditional 90-degree thermal strip installation was time-consuming where each piece is knurled up to three times before crimping and shear testing. This amount of handling increases the potential for marring and damage to the finished material. This new 90-degree thermal strip process employed by Linetec’s  reduces the knurling to one step. This not only saves time and labor, but also minimizes inconsistencies and waste, holds customer-specified tolerances for U-Factor and shear testing, and delivers a high-quality finished product.

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.
