Tilt turn windows with good visible transmittance
Can anyone recommend manufacturers of quality, energy efficient, tilt turn windows with good visible transmittance. If I’m going to put a hole in my wall for a window, I don’t want to fill it with a thick frame and dim glass. The NFRC website lists 64 manufacturers of tilt-turn windows, and I don’t know where to start. I’m designing for zone 5. I am cost sensitive, but willing to pay for quality.
P.S. Am I just cynical, or is the NFRC website specifically designed to prevent consumers from easily comparing different manufacturers side-by-side? They clearly have the data to make ranked lists based on performance metrics.
