Pella Impervia Casement Windows
Hello all. I am a owner builder, building in Northern NH zone 6. I have been reading countless questions and articles on here but here is my first of many questions.
I am looking to build a Net zero home this summer, I am looking at Pella Impervia triple glazed, foam filled frames, casement and a few awning fiberglass windows. They have a U factor of 0.23, SHGC 0.40, VLT 0.49, Low E glass argon filled. I choose Pella due to price, and less lead time than Andersons. I also wanted a all fiberglass window. Some were I read how to calculate U factor to R value, I thought, but I cannot seem to find that. So what would the r value be?
Any one have experience with this window? I will be posting a other question in a day or two running my wall assembly by you all.
Thank you I have really enjoyed reading everyone’s thoughts on this page. It is well worth the prime membership,
