General Information: Serious Materials changed its name to Serious Energy in 2011, and focused efforts on developing programs and products to upgrade the energy efficiency of existing office, commercial and institutional buildings. With both retrofit glazing products for commercial applications and energy management software systems, Serious also launched Serious Capital to finance such projects and eliminate upfront costs for buiding owners.

The company first rose to prominence in 2009, acquiring two recently-closed window operations--Kensington Windows in Vandergrift, Pa., and Republic Windows & Doors in Chicago. In addition to its former Republic and Kensington plants, Serious operates facilities in Newark and Sunnyvale, Calif., and Longmont, Colo. Serious also owns Omniglass Ltd., the Manitoba-based fiberglass pultruder that supplies components to numerous window manufacturers and has licensed its pultrusion technology to others.


Kevin Surace, Serious CEO, has attracted much attention promoting the
idea of upgrading building energy efficiency.
