Ultra Thermal System Provides Improved Thermal Performance and Aesthetic Versatility to Increase Energy Efficiency


Building codes continue to mandate increasing energy efficiency and, as a result, architects, glaziers and building owners are tasked with improving the thermal performance of buildings through the use of thermally efficient products. In response to this growing demand, Kawneer recently introduced its new Trifab® 451UT (Ultra Thermal) framing system during the 2010 AIA National Convention and Design Expo in Miami, June 10 – 12. As an enhancement to the trusted and versatile Trifab® platform, Trifab® 451UT framing system combines superior thermal performance and aesthetics to enhance the beauty and sustainability of commercial or institutional building façades.

Leveraging the successful technology of the IsoLock® thermal break was a key factor in the system’s design. By employing a “dual” IsoLock® thermal break, thermal performance is increased without compromising structural performance. In addition, advanced, thermally broken storefront systems allow building owners to take advantage of tax credit incentive programs and energy efficient certifications, such as Leadership in Energy and Environmental Design (LEED).

Available with screw spline construction and a center aligned glass plane, Trifab® 451UT allows for interior or exterior glazing, meeting the needs of various project requirements. The framing system features a new HP (High Performance) sill design, which incorporates a screw applied end dam, ensuring positive


engagement and tight joints between the sill flashing and end dam. Additionally, a new method of attaching the sill to the sill flashing via a raceway in the sill flashing eliminates the need for a blind seal required by many other flashing systems. Trifab® 451UT has 2-inch sightlines and a 4½-inch frame depth.

Trifab® 451UT not only helps improve thermal performance, but it can meet an array of aesthetic needs. The system can accommodate different color options with anodized and fluoropolymer painted finishes in a variety of colors. Solvent-free powder coatings add another green element to Trifab® 451UT with high performance, durability and scratch resistance that meets the standards of the American Architectural Manufacturers Association (AAMA) 2604.

Perfect for a variety of new and remodeling projects, Trifab® 451UT brings a new level of energy efficiency to the framing system market.
