I'm thinking of adding a heater to my 15x24 above ground pool and also replacing the liner. Would it make sense to put insulation on the floor or walls under the new liner? Has anyone had any experience with Thero-Wall pool insulation or GLI Armor Shield for the floor? Would any of these type of things help keep heat in?
I really meant AG for above ground, not UG. What would that stand for Under Ground?
