Hello,
I was just quoted by a local company in DFW ~$25k to replace 50 windows in my home. The window line they quoted are NT Executive UF .29 / SHGC .21 / VT .50.
The windows are single hung or picture windows, and only 4 of these windows are tempered (although one is a large 72 x 84 picture window).
I read some reviews from several years ago that NT Executive was not recommended because it was a 3/4" window, however it seems that now the NT Executive is a 7/8" window per the specs here: https://ntwindow.com/product/700-series/
Any advice or thoughts would be appreciated.
