Polar Insulation Thermal System
The Polar Insulation Thermal System is engineered to help retain heat, improve energy efficiency, and create
a controlled thermal environment around the spa. The system begins at the cabinet walls, where Weather Guard™ panels are insulated with polystyrene foam and bonded radiant foil, forming an outer thermal barrier. Inside the cabinet, additional one-inch polyisocyanurate insulation panels with reflective foil are strategically installed between framing members to further reduce heat loss.
High-density polystyrene corner insulation panels help minimize thermal bridging, while reflective foil air barriers reflect radiant heat back toward the spa shell. A moisture-resistant polyethylene floor, paired with radiant foil insulation, helps protect the base of the spa while supporting heat retention throughout the cabinet. Together, these layered components work as a system to support consistent water temperature and long-term performance in a wide range of climates.
Energy Saver System
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. 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.
QCA looks for ways to make our spas more environmentally friendly. We use a special energy saving system that reduces energy consumption, which helps you save money at the same time. Unlike full-foam spas that need to vent off motor-generated heat, the heat produced by the mechanical equipment is not vented away in a QCA Spa - it is contained, recycled, and reused. As water moves through the lines toward the jets it draws air with it (an action termed venturi).
This air is taken from the pocket created by the insulation on the shell and cabinet. Not only is this warm air recycled and used to warm the water in your jets, but it also helps to maintain the water temperature! Full foam spas have ventilation openings in the cabinet, which allow the warm air to escape. Those holes in the cabinet also allow insects and critters to get inside your spa.
