Building in a historic district and everything is LEED for Homes. One home is net-zero. HPC requires all wood windows but I need premium energy performance. Who is someone that builds good wood triple glazed windows in the US?

Will they not allow Fiberglass or Cellular PVC windows. The main problem with all wood is that eventually even with the best maintenence (which almost never happens) it will rot or deteriate. Most manufacturers will only warranty their wood windows for at most 10 years and some for only 2 years.
Might be something to consider.

Only wood is allowed. No fiberglass or PVC. Just wood.

they're causing a lot of maintenence for homeowners and a lot of problems for homeowners down the road in my opinion.

Phoenix Windows in Denver for example. But any competent Carpenter should be able to produce something for you.

Wood has a lot of advantages, properly maintained it should out live all the plastic etc alternatives.

That's the problem. wood Windows are hardly ever maintaned correctly. Most manufacturers of wood windows recommend yearly maintenence on windows. checking for cracked paint, blistering paint, etc. And the fact is most homeowners don't think that they should have to inspect their windows every year. That is why fiberglass and cellular pvc windows (which can be painted to a customers specs are used more often.. Also wood contracts and expands which can cause sashes to not operate properly.

All windows need maintenance. Wood is repairable, we just have had 45 windows restored in a very harsh climate which have had very little maintenance. You can not practically repair plastic windows, even the parts are unlikely to be available. Plastic might work on a short term basis, the long term economics are different.

Hello Christopher, Feel free to check Bieber for wood windows. Click on the link below to see the triple pane windows. http://www.bieberusa.com/wood_european_windows_doors.html It is factory finished windows. It last longer compare to onsite brush finish.

Pella Designer series is available is a pseudo triple pane. Not saying that it is your best option but it is one.

Triple-glazed windows have an extra panel of glass, which raises the price substantially. According to Home Heating Guide, triple-glazed windows cost 20 to 40 percent more than conventional double-glazed panes. But with that extra cost comes a variety of advantages that lead many homeowners to decide triple glazing is worth it.

agree with Como most of our projects are Marvin or Pella and have included triple glazed on the north side of homes.

I have Pella Designer triple-pane windows in both high solar gain and low solar gain options. Choice of these windows was based on desire for high solar gain windows that would meet the U<= 0.35 without argon gas fill, since I am at high altitude and gas fills are only available in a very few windows for high altitude, and the builder limited the choice to vinyl or wood since there was little experience with fiberglass by the subs here. I could not get a quote for double-pane windows that had high solar gain, no gas fill, and the U-factor below 0.35 as required by code, and I was nervous about trying to get around the code requirements.

For triple-pane windows the U-values for the Pella windows are on the high side, 0.29 for low solar gain, and 0.31 for the high solar gain, but the high gains are pretty high, SHGC=0.49, and that is dominant in this sunny, heating-only location. RESFEN calculations predicted that windows with much lower u-value windows with lower SHGC (even though labeled as high gain) would use more heating energy due to the loss of solar gain. The Pella windows look much nicer than the standard vinyl windows used in these production houses. Cost to the builder was $35 for the high SHGC windows and $34 for the low SHGC wndows, with the builder absorbing the installation cost. This was 2.5 times the cost of the standard vinyl windows. I have not had them long enough to comment on the durability.

Costs should have been labeled as per square foot in my last posting!
