Tubelite’s dual cavity pour and debridge ultra-thermal barrier storefront line has been expanded and enhanced with the addition of TU24650 Series 2" x 6-1/2" profiles. The dual cavity pour and debridge ultra-thermal barrier decreases U-Factors and increases CRF by 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 plane 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 warranty protection, as well as street appeal.
