I got about a million pieces of 1" thick polystyrene that I wanna stick under the click-lock roof sheets of my shed. Whats the best goo to use without melting the poly and allowing for difference in expansion?
TIA

I have insulated my shed roof with sheets of polystyrene, about 25mm thick. I used Selleys Waterbased Liquid Nails, if you use the solvent based stuff it will melt the polystyrene (instantaneously!).
Most siliones will also work, but the liquid nails will "grab" quicker.
