I have some of those insulation pillows that you stuff in the vents in the wintertime. My question, do any of you use them to help cut down on the heat in the summertime? Does it help?
They work very well, but I pushed mine in so many times it bowed the screen up into the fan. Got vents with double walls from Fantastic fan at a rally. They are great and I got rid of the little "pillows".
