Select your spa cover core insulation:

The heart of any spa cover is the foam core it is built upon, tapered for rainwater runoff. Core thickness, foam density, and grade determine the spa cover's insulating value and strength. DuraTherm's 4" > 2.5" taper hot tub cover with superior closed-cell EPS insulation has higher R-Value, and is much stronger than other brands which taper down to a flimsy 2.0". Our models with a 5" > 3" taper provide even better strength and optimal insulation. We use dual 20-gauge carbon steel C-channels for reinforcement, not thin 22-gauage as some other brands use.

After selecting your core model, you'll choose from 15 great colors, indicate shape, dimensions, and select options such as Double-wrapped Core, Full Heat Seal, and Energy Reflex.

TIP: Covers more than 5" thick are not recommended because they are too heavy and bulky for easy removal or use with most cover lifting devices. Covers thicker than 5" provide negligible insulating gains.

NOTE: Many other brands of spa covers use inferior, low-grade foam cores which will rapidly absorb moisture and quickly lose their R-value and strength. DuraTherm uses only aquatic-grade foam cores. For example, our 5">3" taper spa covers actually provide superior insulation, strength, and durability compared to an unwieldy 6">4" taper cover using cheaper construction-grade foam cores.

Energy Reflex HIGHLY RECOMMENDED OPTION: The Energy Reflex upgrade is an advanced metalized infrared reflective shield, which acts like a thermal mirror. Radiant heat, which would otherwise escape and be wasted, is reflected back down into the spa water. This inexpensive upgrade is a breakthrough which could pay for itself in reduced energy consumption year after year.
