Why Superior Quality Counts
The color, luster and graceful sculpting of the hot tub shell on a Sundance® spa makes a beautiful first impression. But there is much more to a Sundance hot tub shell than meets the eye. Our exclusive 3-layer Rigid Bond construction process adds durability, high performance, and superior heat retention capabilities to all of our hot tub shells.
Rigid Bond is the only process that layers the acrylic surface material with three components: vinylester, polyester resins and a proprietary laminate. Without getting too technical, the vinylester resin provides lasting adhesion with the acrylic layer. The polyester resins are created from a proprietary blend that makes a Sundance hot tub shell eight times stronger than ordinary fiberglass-laminated shells.
Rigid Bond construction is the reason why your hot tub shell performs so well through years of use and exposure. The acrylic layer that you see is built to last, retaining its color and sheen with very little maintenance.
Energy efficiency is built into our hot tub shell construction, too.
- Two types of foam are used to provide full-foam insulation. It completely fills the compartment between the shell and the skirt, helping to maintain water temperatures longer.
- High-density, heat-resistant foam surrounds the equipment bay; lighter foam insulates elsewhere for an energy efficient hot tub.
- The pairing of Rigid Bond and insulation conserves energy and helps you save money on heating costs.
When you’re comparing the value of hot tub brands, it pays to look at the way a spa shell is put together. Rugged durability, superior performance and energy efficient properties are three areas where Sundance Spas’ Rigid Bond beats the competition.
