Fibersteel™ Construction

Durability is paramount with it comes to your home investments. That’s why Cal Spas hot tubs utilize the exclusive Fibersteel™ Construction Process. The finest acrylic sheets are vacuum molded into shape, then reinforced with vinyl ester and fiberglass. After curing, the shell receives a resin filler coat, fiberglass and calcium carbonate. Stiffener reinforcement supports and 1.5 inch angled irons are added to ensure maximum strength. A final filler coat is applied to seal, bond and toughen the overall structure.

Bio-Clean™ Antimicrobial Filter with TeleWeir Gate

Our Eco-friendly Bio-Clean™ Antimicrobial Filter utilizes a special bacteria-fighting agent that is molded into the fabric. This unique protectant prevents harmful microbes and bacteria from reproducing and re-entering your water system ultimately minimizing the need of chemical sanitizers during regular cleaning and maintenance.

Thermo-Shield™ Insulation

Insulation Cal Spas Thermo-Shield™ insulation system starts by installing a unique material primarily comprised of post consumer recycled denim. This 3” thick insulating material foundation is then thermally bonded with a 99% pure aluminium reinforced foil sheet on one side creating a radiant heat shield which directs motor and equipment heat back into the spa, retaining residual heat and increasing energy efficiency. Next, we install a layer of dual walled reflective bubble foil to the floor area of the spa to reflect heat upward into the spa seat and floor. Finally we add an ABS liner or ABS moulded pan that locks in heat and keep moisture out.
