Triple-glazed fiberglass windows – Zone 5A

jhrockwell | Posted in Green Products and Materials on

What options exist presently for affordable triple-glazed fiberglass windows in New England? I like the wood interior of Integrity, but wonder if anybody has found windows that hit a sweet spot of performance, price, reliable customer service. Until recently, I’d been considering Intus windows, but ultimately don’t want PVC or unpaintable, white interior sash and frames. Thanks!

    John,
    This question comes up frequently. Did you read the responses to the last thread on the same issue?

    I did not. Thank you.

    Would you consider a solid wood triple glazed window rather than fiberglass? My company is Lothlorien Woodworking, located in Ontario, and we've delivered frequently in New England. Krypton gas fill, warm edge spacer, thick wood construction, triple weatherstrip, all make for a pretty high performance window. NOT tested in the labs.
