The ONLY way to insulate an Indoor Pool is with FoamRite's "Closed Cell" spray foam insulation. The foam adheres well to both Studs and sheeting completely sealing this high humidity room from the rest of the house.
Unlike other forms of insulation FoamRite's spray foam insulation does not absorb moisture. Moisture in the wall cavity or attic is a perfect recipe for the growth of mold. The elimination of mold can cost thousands and thousands of dollars. FoamRite's spray foam insulation is resistant to moisture giving protection to those areas highly susceptible to mold.
