I recently began to insulate my garage door and have a question. I used 1 inch styrafoam because the other available styrafoam was to thick to fit in my door slots. I have installed the sheets of styrafoam and now need to decide how to finish it cosmetically. I haven't had any luck finding advice on the internet and I was wondering if you could offer any. I looked at many different hardboard, tile board, thin wood and paneling options to finish it off. It was difficult however to fit the sheets of styrafoam in to the slots because I had to snap them into place....so they kind of weren't really secure. At that point I used window foam to fill in the gaps and secure them. I thought I could simply place whatever paneling inside the slots too but they way my door is set up I don't have a hard surface to mount them to with the styrofoam behind them. I am considering getting some vinyl or something thin to mount to the surface of the slotted sections to cover the foam. I think it will work but it won't sit right up against the foam. It will mount to the flat edging of the door but there will be about 3/4 " of space between the foam and the vinyl. Will it still insulate well? Can you offer any advice to an amatuer do it yourselfer?
