So I finally built a permanent deer blind cuz I'm sick of buying $2-300 pop up blinds every other year when they get ripped down by the wind and snow. I am ordering Windows from deerviewwindows.com and I'm wondering how I'm going to keep them from fogging up when I crank up the buddy heater in late season?Insulated glass windows were out of the question because I wanted more wide(about 4') than tall windows for being able to see out of it better. I will more than likely have the windows open most of the time while sitting unless it's super cold. Anyways does Anyone got any bright ideas or something that has worked for you to keep the fog off the Windows in a heated blind late season?
