Hurricane Resistance Thermal Aluminum Window Framing System

Trifab® VG (VersaGlaze®) Framing systems are built on the proven and successful Trifab® framing platform – with all the versatility its name implies. Trifab® framing set the standard and Trifab® VG framing improves upon it.

There are enough fabrication, design and performance choices to please the most discerning building owner, architect and installer. Plus the confidence a tried and true framing system instills.

Select from four glazing applications, four fabrication methods and multiple infill choices.

Consider thermal options and performance, SSG and Weatherseal alternatives and your project takes an almost custom shape whether your architecture is traditional or modern and the building is new or retrofitted.
