Thermo-Twin windows include insulated glass for enhanced efficiency. All insulated glass units are manufactured at Thermo-Twin using state-of-the-art Lisec equipment and incorporating the Super Spacer® glass sealing system. Super Spacer® equips windows with “warm edge” technology, which maximizes overall energy efficiency.
To further enhance energy efficiency, all insulated glass units are 7/8” in overall thickness. Additionally, all glass panes are 1/8” in thickness, providing for strength and years of problem-free service.
