Best source for high solar heat gain windows?
Hi, I would like to replace a few of my downstairs windows on the south side of the home to allow the sun to actually heat the interior space.
Those windows are typical low-e glass that shuts out the sun as well.
When I first investigated this issue around six years ago I found that most of the standard window brands did not offer this kind of glass as a “standard” option.
What brands do offer it without charging you 2x or 3x the price of a conventional “low-e” window?
From another post I saw mention of “Cardinal LoE-180 glass with SHGC=.69, U=26”. I suppose that I could live with anything in the range of 0.5 to 0.7 which is much better than the windows we have now.
Thanks for your help,
