Evolution Triple-Bond Spa Shell

Evolution Spa shells are manufactured using a triple bond process resulting in the industry’s thickest and strongest shell:

  • Production begins with a genuine Lucite™ Xtra acrylic sheet
  • This is further co-laminated with a vinylester bonding layer. This secondary layer acts as a vapor barrier and ensures the uncompromised adhesion of the third and final strengthening layer…
  • StrongBond™

StrongBond™ is a revolutionary polyurethane component which has superior tensile, flexural and impact strength over traditional fiberglass and styrene materials. It is Styrene-free, thus eliminating release of this polluting gas into our environment. Styrene ranks among top 10 air pollutants in North America.
