Tubelite’s 950SG Series Therml=Block Window Wall system was honored as a 2023 Glass Magazine Award winner in the category of Best Framing System or Component. Tubelite will be recognized in Glass Magazine and was recognized at a ceremony at GlassBuild America: The Glass Window & Door Expo in Atlanta, which took place Oct. 31-Nov. 2.

Tubelite’s 950SG four-side, structural sealant-glazed window wall provides mid- to high-rise commercial buildings with a thermally broken aluminum framing solution that presents the look of curtainwall and the economy of slab-to-slab framing. Engineered for between-slab horizontal spans on commercial buildings, the system’s dual-strut, ultra-thermal barrier contributes to high-performance, energy-efficient building envelopes.

“The 2023 Glass Magazine Award winners provide incontrovertible proof that glass is beautiful and can do almost anything inside and outside of a building,” Glass Magazine said. “The… six product award winners represent the full gamut of what glass and metal systems have to offer to the spaces where we live, learn, work and play.”

“We’re thankful to Glass Magazine for the award and for honoring the benefits of Tubelite 950SG thermal window wall,” said Steven Gille, pre-construction services manager with Tubelite. “This aluminum framing system saves installation time and labor while meeting more stringent model energy codes and supporting LEED certification. Saving labor on the job site, our 950SG thermal window wall is installed entirely from the building’s interior. Our streamlined system is designed with fewer parts and steps and less installation time in the field.”

A vertical, extruded silicone gasket eliminates the need for an exterior-applied wet seal, and a single-piece anti-buckling clip simplifies installation. Tubelite’s 950SG Series 2.25-inch-wide thermal framing has a system depth of 6 inches. Extrusion and brake metal options are offered for integrated slab edge covers. Three sill variations are available as 3.25-inch standard, 2.25-inch low-profile and SSG with no exposed metal.

Tubelite’s 950SG Series thermal window wall with SSG sill achieves a U-factor of up to 0.33 for thermal transmittance, per NFRC 102, and a frame condensation resistance factor of 82, per AAMA 1503. The system also has been successfully tested to meet industry standards for acoustic, air, water and structural performance.

“For a complete high-performance framing package, Tubelite 950SG Window Wall easily pairs with other Therml=Block products, including our TerraPorte terrace doors,” Gille added. “Even in extreme cold climates, our Therml=Block products deliver superior energy and condensation resistance performance while providing structural integrity, design creativity and sustainability.”




Tubelite further supports building teams’ environmental goals and product selection with material transparency and documentation. The aluminum used to produce Tubelite’s 950SG Series window wall framing can be extruded using EcoLuminum, an aluminum billet composition with a high recycled content. The aluminum is finished in a choice of high-performance standard anodized or paint finishes. Specialty finishes, custom colors and dual finishes also may be specified.
