Edge-to-Edge Insulation®

Edge-to-Edge Insulation®: more heat = lower power bills

The defining feature of a hot tub is warm water, and when you choose a spa with Edge-to-Edge Insulation®, an exclusive, full cavity insulation from Hot Spring, you’ll enjoy more heat, and save money on energy costs in the process.

Dense, flexible, ultra-efficient insulation

From the wool-like FiberCor® found in our Hot Spot and Limelight collections (4x denser than standard foam), to the unmatched multi-density foam of our Highlife spas, our Edge-to-Edge Insulation® is a key reason why we’re the most energy efficient spa brand in Australasia. Leaving no gaps or thermal voids, and denser than the rest, your water stays warmer in a Hot Spring.
