how to gauge window quality
I'm looking into buying a new window for my bathroom. I'm installing them myself.
Home depot gave me a quote for $170. windowestore.com gave me a quote for $400. I'm going to get more quotes this week, but what should I be looking for? I live in NY and just want to make sure the windows can keep the cold out.
Both windows are lowe3 with argon, double pane.
Windowestore gave me the following info "Double Strength Glass- Double Pane- Super Spacer- Half Screen- Low E3 366 Max Performance Glass Package- 1" Overall IG Unit- Argon Gas- EZ Clean Tilt in sashes U-Factor .30 +/- SHGC .20 +/- Blocks approx. 99% Heat and Cold- 3 1/4" Frame depth Double Lifetime Warranty Lifetime Glass Breakage Warranty"
I tried to look online for windowestore.com reviews but couldn't find any. Anyone know if there windows are any good?
