INSULATION

Cal Spas Thermo-Shield utilizes environmentally-friendly technology to keep the soothing heat of your tub’s waters locked in at all times. First, a 3” thick insulation material comprised of post-consumer recycled denim is thermally bonded with a 99% pure aluminum reinforced foil sheet creating a radiant heat shield.

This technology directs the system’s residual heat back into the spa for increased heating efficiency. A dual-walled layer of reflective bubble foil is installed under the spa’s floor to reflect ambient heat upward throughout the tub. Lastly, a unique thermoplastic polymer liner locks in heat while keeping external moisture out.

Your Cal Spas tub will always be as warm and inviting as the last time you left it thanks to our Cal-Armor 4” to 2” tapered hot tub cover. Constructed of ultra-durable polyester, our covers are specially designed to maximize heat retention and protect your hot tub from the elements.
