High 'R' Value and Low 'U' windows?!
Hi window people --
The house we're building is in the LEED for Homes Pilot Program. "LEED" stands for Leadership in Energy and Environmental Design. In our area (North East) we need to have a U value of atleast = 0.35, = 0.32 is better, as it gets us a point, and = 0.30 would be ideal.
I'm finding it difficult to find this on all the websites. The Pella windows we've chosen have an "R" value of 4 (which is a U of 0.25) but they are VERY expensive. We have primarily casement style windows, with awnings up high, and a few sliding glass doors... and a couple rounds...
Can somebody recommend a good quality window to fit our needs? We would like wood inside, and cladding out is fine! You can see plans for our house on our blog...
Thanks in advance,
