North Sound Energy & Remodel donates, installs new window-insulation product at Whatcom Center for Early Learning

North Sound Energy & Remodel, a Bellingham-based home performance contractor, has donated and installed a new window-insulation product on the historic home of the nonprofit Whatcom Center for Early Learning.

The product, manufactured by the Portland, Ore., company Indow Windows, is an acrylic insert that “becomes nearly invisible” when pressed into place on the inside of a window frame. The inserts are custom-measured, the company says, and do not mar historic trim work, provide a tight air-seal for single pane windows, eliminate cold drafts and condensation, minimize lead paint dust contamination and reduce street noise.

“We wanted to bring attention to the ways these thermal inserts can benefit historic homes,” North Sound’s owner Kurt Waldenberg said, in a March 2 release. “We believe in all the great work Whatcom Center does for kids with special needs, and we wanted to show that Indow Windows are a great fit for Bellingham’s historic homes.”

The energy and remodeling company plans to give the nonprofit donations of 10 percent of every window product purchase by supporters, board members and employees of the center.
