My local Williams home center carries one brand of vinyl window - Kasson & Keller. Their web site is at http://www.kas-kel.com/index.html . Their double-hung new construction windows (200 series) with no frills (just the lowest of the lowE) run $185 ($350 list) from them, not installed of course.
Looking at the window's efficiency ratings
http://cpd.nfrc.org/pubsearch/psLineDet ... -K-9_10187
it doesn't appear to be in a top category and I'm going to guess they don't use TPS or SuperSpacers or whatnot that I've read on here about. But someone else did ask about them once before and got no response.
So here I ask - any experience with these windows?
Thanks in advance!
