Meet the next great advancement in windows: the multi-cavity, multi-coating glazing system of Ultra-R. It uses advanced, coated films suspended inside a premium low-E unit to create as many as four super-insulating, gas-filled cavities.
Available on all Hurd products, Ultra-R glazing achieves the highest insulation values in the window industry—from an impressive R-6 for our standard single film, argon-filled unit, all the way to an unprecedented R-20 for our custom triple film, krypton-filled techno-wonder.

"Heat Mirror glass utilizes advanced, coated films suspended in the middle of an IG unit. The films have nanoscale coatings of metal to reflect heat back to its source, improve thermal insulation, block UV rays and noise, and improve owner comfort & economy dramatically." - State-of-the-R. (White Paper on Professional Builder website)
"The Ultra-R direct-set window uses Heat Mirror film technology by Southwall Technologies to achieve a center of glass R-value of 20. The film is coated with nanoscale metal particles that reflect heat back to its source, improving insulation, blocking UV rays, and reducing noise." - Builder Online
