Alpen High Performance Products, a designer and manufacturer of insulating doors and windows, announced the expansion of its Alpenglass insulating glass unit production in Colorado.

Alpenglass combines its Heat Mirror suspended coated film with low-E glass technologies for commercial and residential window projects.

Additionally, the company will collaborate with Kensington HPP in Vandergrift, Pa., to address demand in the Eastern U.S.

“From its inception more than three decades ago, Alpen has been a proud and preferred fabrication source for Heat Mirror [insulating glass units],” says Brad Begin, CEO of Alpen. “Following Eastman/Southwall’s decision last summer to exit Heat Mirror manufacturing, we have made significant investments to increase our own production capabilities in order to meet growing demand for super-insulating, energy efficient glass products, while broadening our ability to produce other high-performance glass combinations featuring emerging technologies.”
