Greetings
I have a shed in a cold part of NSW.
The shed is insulated, roof and walls.
However the roll a door has no protection.
Could I apply some sort of product, like a paint, to the back of the door.
I'm trying to reduce the heat from the outside coming through the door and alternatively keeping the heat in during winter.
Any ideas, does such a product actually exist? :confused:
Thanks
Pulpo
