Tubelite’s dual thermally broken storefront line has been expanded and enhanced with the addition of TU24650 Series 2” x 6 1/2”.

Beauty and Performance

The dual thermal break decreases U-Factors and increases CRF over a single P&D pocket when using the same size and type of insulated glass. Azon’s Lancer® mechanical lock provides long-term resistance to shrinkage of the polyurethane barrier. The glass pane matches that of our 4 1/2” system depth for a pleasing reveal on the exterior and interior sides of the frame. Seven anodized finishes and 20 standard paint color are available on this storefront framing system to complement any project with warranteed protection, as well as street appeal.

TU24650 Dual Pocket Poured & Debridged Thermal Storefront is recommended for use on ground floor storefront or protected low-rise applications. Framing has 1/2” bite for use with glass or panels up to 1″ thick. Verticals can be steel-reinforced for high performance against strong windloads. Tubelite 3700 Series operable windows can be glazed into the storefront framing pocket for natural ventilation.

Members can be assembled using screw spline or clip joinery, and framing is compatible with Tubelite’s Medium and Wide Stile Therml=Block™ Doors.

Our TU24650 Series Storefront products are subjected to thorough testing by an independent laboratory, ensuring that you get the highest quality storefront framing products that the industry has to offer.
