Kolbe, Eagle, LoE options for SHGC?
I am shopping for windows (some new, some replacement) for primarily South-facing windows and a few East windows. We are in a temperate climate in the SF Bay area - 55F/35F in Winter and 60F/77F in Summer. Given all the posting and research on various forums (especially this link:
thanks oberon!), and our architects rec, we think we should be looking at windows with a higher SHGC as we are primarily a "heating climate". There are some summer days when we bake from the heat, but they are few. Plus the architect has designed overhangs for some of the sunnier spots.
I have looked at Marvin, Loewen, Kolbe, Eagle and Jeldwen just to get an initial baseline. They all use Cardinal glass and in fact they all offer as their standard LoE-272 EXCEPT Kolbe which uses LoE-270 (anyone know why?). I've ruled out Marvin (not in our budget). So that leaves Loewen, Kolbe, Eagle and Jeldwen. Here is what I was able to gather from their quotes for a baseline/sample window. I have to go back and ask for which of these companies offer the Cardinal LoE-180 option, but this is my place to start (and some of our East windows will use standard anyway).
Casement 36" x 48" Aluminum Clad, wood interior, Double Pane/Argon fill
Kolbe (270) U=0.35, SHGC=0.25, VT=0.46
Eagle (272) U=0.30, SHGC=0.29, VT=0.49
Jeldwen (272) U=0.33, SHGC=0.26, VT=0.48
I'm still waiting for Loewen's official numbers based on my quote, but I'm guessing they will probably be a little better all around based on what I could see as a very high quality window.
Price-wise from most to least expensive it's:
So, for the price/value it seems like Eagle might be a good choice for us. Has anyone had experience with Eagle either good/bad? Any thoughts on their new Aluminum clad casements with the Fibrex thermal barrier? (I'm guessing that is how they get the better Uvalue??)
I actually liked the aesthetics of the Kolbe window more than Eagle, but their numbers aren't as good. I also really liked the Loewen product as it feels so solid but that option might prove beyond our budget. Jeldwen's were OK, but I didn't quite feel as solid as Eagle or Kolbe so I'm really not considering them any longer.
