I had Milgard replacement windows installed many years ago. Back then the “conventional wisdom was that expanding foam would warp the windows and even Milgard discouraged foam. My installed used some low expanding foam shot from guns and had no warping issues. I later installed more windows myself and bought the same low expansion foam. Given that my SoCal 2100 sq ft SoCal 2 story house has 400 sq ft of windows, I’m so glad my installer, Newman Windows, did not list to conventional wisdom. I have so many other issue with this 1987 tract home that I’m glad this upgrade was done correctly. Now if I can only convince my HVAC contractor that a 4 ton AC, even with 5 stages, is too large for my home. Seems like even a Manual J doesn’t sway them. But that’s for another blog, lol. Thanks for the great site!

I have seen low-expansion
I have seen low-expansion foam available. I use the same for everything, but the windows that I use are Viwinco impact rated with very solid frames, so I have had no problems with expansion moving the frames around. We foam everything.

Does closed-cell foam come in
Does closed-cell foam come in the low-expansion variety, Thomas?

Remember that the 2012 and 2015 IECC require that non air permeable air sealing be performed around windows and doors in new homes.

Good point, Thomas. Closed
Good point, Thomas. Closed cell spray foam improves the structural strength of buildings.

We are a large window and door retailer and installer in New England . I agree with both Kevin and Thomas ; all too often Builders and installers just think one sided. This both an interior insulation issue and proper exterior sealing issue. Both from cold migration and air and Moisture sealing. Great article and proof-telling pictures
