Thermo-Shield Spa insulation
Cal Spas Thermo-Shield™ insulation system starts by installing a unique material primarily comprised of post consumer recycled denim. This 3” thick insulating material foundation is then thermally bonded with a 99% pure aluminium reinforced foil sheet on one side creating a radiant heat shield which directs motor and equipment heat back into the spa, retaining residual heat and increasing energy efficiency. Next, we install a layer of dual walled reflective bubble foil to the floor area of the spa to reflect heat upward into the spa seat and floor. Finally we add an ABS liner or ABS moulded pan that locks in heat and keeps moisture out.
