Acrylic Block Windows

Energy Efficiency Options
Triple-paned and solar tinted acrylic block windows.



Hy-Lite's three energy-efficiency options feature the decorative sparkle of designer windows while providing the energy efficiency of a modern Low-E window.

E3 Triple Glaze
Our innovative triple-paned acrylic block creates two air gaps in the window, which increases the insulative power of the window. This triple-paned block is available in both Wave and Glacier styles and is ideal for cool climates.

E3 Triple Glaze provides U-values as low as .32. Contact customer service at 888.256.2599 or start a web chat with us for the most up-to-date U-values for each series window.

E3 SunBlock
This solar-tinted acrylic block reduces heat transfer from harsh sunlight and protects the home's interior from harmful UV rays. E3 SunBlock reduces the solar heat gain coefficient (SHGC) through infrared absorbers and UV-inhibitors in the acrylic resin. This block also features our E3 Triple Glaze technology, providing the most energy efficient acrylic block to date. Ideal for all climates.

E3 SunBlock provides SHGCs as low as .19. Contact customer service at 888.256.2599 or start a web chat with us for the most up-to-date SHGCs for each series window.
