Here are some photos from a recent project. This is an addition to a huge old barn which had a fairly recent Timberpeg addition to it. I did some work with the addition plus a larger new addition in a Greek Revival style with wrapping porches to create a more cohesive whole (and add a bunch of space) The addition is framed with double stud walls and super-insulated. Windows are triple glazed double hung. Fiber cement siding over rainscreen.Enjoy.
"I was surprised while traveling in Sweden two years ago to learn that triple-glazed windows have been, essentially, required by code in that country since 1976." Alex Wilson writes in a Green Building Advisor article. He also mentions Serious Windows which I have been hearing a lot about lately and am anxious to try. Pricing seems very good and I have heard tell that the quality is excellent. I believe that parts of the U.S. will move towards such code legislation in the near future as the severity of the global climate crisis becomes more obvious to Americans.
The more I learn about windows, the more I am sold on Fiberglass windows. Thermal rate of expansion issues are completely bypassed and I think this is the cause of most failures. The thermal performance of fiberglass frames is incomparable. For the Perry Road project we are looking at: Integrity by Marvin Windows - www.integritywindows.com
Acurate Dorwin out of Canada offers tunability of glazings so you can get more solar heat gain in our Northern climate on south facing windows (American windows are all about blocking heat gain. www.accuratedorwin.com
Fibertech - just started looking at these. www.fibertec.com
thermotech - these seem really nice but no double hung. Seems rather myopic to me. Around here we have our windows open 5 months of the year and sometimes you need a double hung
No idea of pricing and lead times yet.
I'll let you know how it goes
