Please help me. I want to cover a gap between my garage and pergola. I have no place on top to place the polycarbonate as there is some guttering on garage.
Is there a way I can screw the polycarbonate sheet between the 2 walls. Please see diagram. It could be any material whether aluminum, timber plastic sheets,etc. Anything with a lip so I can screw in between the 2 walls. The cheaper the better. thanks
thanks
Edna
