We only use Continuous Cast Acrylic (CCA) for many good reasons!
Our CCA includes UV inhibitors that prevent color fading when exposed to sunlight. The surface of a ThermoSpas shell is smooth and luxurious to the touch, yet durable enough to resist stress cracking and easily withstands temperature changes from minus 50ºF up to 180º F. Other materials commonly used to construct a spa shell; gelcoat, OAS plastic, and inexpensive composite acrylics often fade over time and are susceptible to signs of aging. Those constructed merely of a vinyl liner are easily damaged and often require repair or replacement in a few short years. Plus, CCA is a non-porous material which makes it simple to clean. ThermoSpas shells will look beautiful for generations to
come and require very little maintenance.
The shell is the most important component in a hot tub!
In 2002 ThermoSpas formulated the ThermoBonding process that is used to manufacture every ThermoSpas hot tub. The result is an unprecedented 0% failure rate on tens of thousands of our spas built since that date. ThermoBond has allowed us to provide an industry-leading 20 Year Warranty. Always remember, pumps, heaters, filters, and other parts can easily be repaired or replaced—the shell cannot.
A checklist found on no other spa:
Consistent Quality and Green Technology
A unique digital application program is used to monitor the thickness and resin/fiberglass content of each shell, guaranteeing optimum consistency and weight. Every shell is built with an unprecedented weight variance tolerance of less than 4% compared to well over 25% by most competitors. This provides high structural integrity and minimizes manufacturing flaws. Our structural shell design eliminates the need to use ozone layer depleting foam for support which helps keep our spas more “earth friendly.”
