I bought a couple of sheets of 50mm Celotex to cut up and fix to loft hatches to insulate 'em. These were the 1200x450 sheets labelled for cavity wall use as they were a decent size to get into the car.
Now, I want to seal up the edges so they don't degrade over time as I use the hatches. Would Duck tape be OK for that? I don't want to use something where the sticky will react with the material.
Also - these sheets are faced with foil or whatever - can I use white wood glue to fix them to the plywood hatches?
Thanks,
