Question on OKNA windows
I have recently had installed a project that included some OKNA 800's, 500's and Starmark's. Mostly double hung windows.
On many of the Windows (all three types) when you put your hands near the slider tabs that you would engage to tilt the window, I am feeling cold radiating from that spot. I am not really feeling much air movement - it seems to be very slight. I am a little surprised given the AI rating on all three types of OKNAs. The slider tabs are also quite cold.
Any comments on there on this. Is this normal?
