Thanks WOW, but i was looking to see if they had a spread sheet like Simonton's that list 28 test sizes just for the 5500 alone.
If Simonton wanted to hide there AI numbers they could just not post them on there website.They could also be deceitful and post a 0.07 AI number for a 53x71 and put a disclaimer in small print.
Does anyone know if Simonton test their windows with sash reinforcement. The Okna listed does and this can greatly enhance AI performance numbers, up to a 0.04 difference on some of the Soft-Lites I have seen data for.
What is the standard test size for a slider?
