Those that know windows, Vinylbilt Diamond Series windows (triple glass, double low E-180, Argon) versus Vinyl Windows Design Premium windows (3.5" PVC, TempSmart foam warm-edge spacer, hardcoat low E glass and argon) . Which are the better of the two and what are the pros and cons of each and things to look out for.
I've received quotes to do 17 windows (will probably go with just 10 as rest are really large) from two companies and they are essentially equivalent so now I've down to looking at the quality of the windows each is going to put in and the installation. In terms of window quality, which windows are better (Vinylbilt Diamond versus VWD Premium) and why and what should I look out for.
Thanks in advance for your insight.
