QCA Spas are built to withstand harsh, northern winters. Our system incorporates insulating styrofoam panels with an additional layer of reflective foil as well as reflective foil insulation on the floor. Unlike other insulation systems that loosely wrap insulation around the shell, QCA Spas, Inc. sprays our insulating foam directly onto the shell surface of spa models that include foam on the shell to ensure full contact to all surfaces, thereby sealing the cabinet from any outside air infiltration. As a bonus of this excellence in insulation techniques, the dead air space within the closed spa cabinet forms an insulating barrier to help maintain spa water temperature. This is the same insulating principle as found in the construction of insulating thermos bottles.
The bottom of the spa is sealed with a moisture proof material to further protect and insulate. Your spa can be fitted with your choice of cover, which can also be locked in place for safety. We recommend the thicker, highly insulating covers for colder climates.
