Spa Insulation

PDC Spas TemperLOK™ insulation system provides maximum energy savings while maintaining a lightweight unit for easier installations. The use of a strong fiberglass, non-filled resin backing with an insulating foam coating provides maximum strength and efficiency. Using this process, a PDC Spa is more costly to manufacture, however, each and every PDC spa unit is made with quality and efficiency in mind.

With the PDC Spas TemperLOK™ design, simply remove any of the side panels, easily view the backside of the spa shell, complete maintenance and replace the panel. Quick, efficient, and economical. Your spa remains strong and thermally efficient.

Servicing the opposing foam-filled units can be a nightmare. If your spa leaks, finding the leak is a huge expense as service technicians are forced to dig through the foam to uncover the source. You're left with a spa that now has no foam (you're without thermal retention and shell strength) and a big bill.

Energy Efficiency

PDC Spas has engineered a unique system that maximizes energy efficiency and minimizes heat loss rivaling our foam-filled competitors. Unlike foam-filled units which hide manufacturing defects and make servicing expensive, the sophisticated engineering of our TemperLok™ system keeps the spa lightweight, economical to own and operate.

All PDC Spas are protected from cold, damp, and outside elements with a multi-layer bottom construction. A tough ABS plastic material covers the entire bottom and tightly wraps up the cabinet sides. A layer of pressure-treated plywood is added for strength, while a layer of thick foam is sandwiched between the ABS and plywood for superior insulation. An inside reflective thermal barrier ensures outstanding thermal efficiency.

TemperLOK Insulation

The TemperLOK™ system begins with:

(1) Urethane foam backs the spa shell to prevent spa water heat from escaping. Not overdone, as a minimal amount of heat is actually lost through the spa shell.

(2) Thick cabinet sidewalls are backed with a full 3/4" insulating foam panel, faced with a reflective thermal barrier. This keeps cold air from entering, and warmed air from escaping.

(3) The TemperBase™ spa floor is a multi-layer design of tough, durable plastic, 1" thick insulating panel, pressure-treated plywood facedwith a reflective thermal barrier.

(4) A rubberized gasket seals the cabinet sidewalls tight to the spa shell completing the cavity of trapped air.

(5) A thick thermal cover prevents heat from escaping. This is an important feature of energy conservation as most heat escapes from the water surface; compare this to steam escaping from a styrofoam cup of hot coffee. Only the highest quality covers are offered at PDC Spas.
