If you have a stair case going to your attic it is attached inside the attic, you unzip it to get in it keeps the hot air in the attic instead of coming inside your house. Seals it up. 4951
We have a silver insulated box basically pink insulation between silver metal stuff about 3/4 inch thick that weighs about 3 Ounces. You just lift on or off when you open the stairs.Kerry (cam contracting) made it for us. 4951
We have a tent in the house over the stairs to the attic; but not in the garage. We keep that door open a bit in the summer to let the heat flow through. Our garage is not air conditioned.  4951
There is a big market for those attic tents.an there not cheap .I look on line for my house because i had the same issue. I thought I can do something like that for a much better price. And to answer your question i can open my attic door in 100 degree heat and you get no transfer of heat.I have sold many to customers of mine here on the board. 4951
