Pultruded fiberglass profiles conduct heat at a small fraction of the rate of aluminum and expand and contract at nearly the same rate as the glass they hold, so seals stay tight through temperature swings. The frames can be finished in a wide array of durable factory-applied finishes to complement any design.
We offer low-emissivity materials and package solutions to optimize systems and ensure the perfect solution for every requirement.
Owners have a wide array of custom options. They can specify dimensions, colors, weather seals, hardware, warm edge spacers, glass packages, subsills, receptors, and trim packages.
