The POLAR Master Insulation System.
At Master Spas, we believe you deserve to know the truth about your spa's energy use. Many companies would lead you to believe their spas are the most energy efficient because they fill them with foam insulation. Well, it's not that simple. The truth is, they rely on the foam insulation for structural support. We have a better way. It's called the Polar Master insulation system, and its been confirmed by an independent testing lab that no fully-foamed spa is more energy efficient than a Master Spa with the Polar Master system. However, at Master Spas, the choice is yours - full foam insulation is available on most models at no additional cost.
Here's how the Energy Efficient Insulation works:With superior structural support provided by the finest vinylester rigidizing laminates, our industry-leading system operates on the same principle as a thermoplane window - by trapping warm air between two layers of high-density insulation. In fact, the pocket of air is warmed by the heat put off by the pumps and heater - converting precious energy that would otherwise be wasted, into money-saving efficiency. In addition, your Master Spa features a solid, non-corrosive bottom for years of support and protection
