Designed to add increased thermal performance and value, Kawneer’s new addition to the company’s trusted Trifab® platform gives you more. More flexibility. More thermal options. More design choices. Flexible enough for a wide range of building projects, Trifab® VersaGlaze® 601 Series Framing Systems have a 6" depth, which accommodates higher spans than conventional 4-1/2" storefront framing systems. The 3-in-1 series includes the non-thermal Trifab® 601, the single thermal break Trifab® 601T and the dual thermal break Trifab® 601UT. The greater system depth combined with three thermal performance options make this one of the most versatile framing systems available.
