So I've just had an in ground pool installed and have yet to pour any concrete around it. I have quite a bit of rigid 4" expanded polystyrene foam roofing panels I got from a construction friend that I could put around the walls of the pool with out much work except digging out the back fill down to the poured concrete collar at the bottom of the walls to get the panels glued to the walls. I'm also planning on having a pool cover to reduce the evaporative losses which I understand are the highest source of loss. I understand foam loses its insulating value when wet but from my understanding polystyrene is waterproof?? So given the above info do you folk think it worthwhile to add this around my pool?
