Smarter Construction, Stronger Covers
Engineered for strength & efficiency.
Every Core spa cover is built for lasting performance using high-quality materials. We use virgin foam for superior strength, durability, and improved energy efficiency to help retain heat and lower costs. Each core is wrapped in a specially formulated plastic that resists water vapor far better than traditional materials, helping prevent saturation and maintain insulation. The result is a lighter, longer-lasting, better-performing cover.

High-performance materials that hold up
Premium materials, expertly crafted.
We use only top-quality materials to make spa covers that last. Our 28 oz. marine grade vinyl is treated with UV and mildew inhibitors for long-term outdoor durability. WeatherShield™ offers performance that is three times stronger and 25% lighter than vinyl, making it easier to handle without losing strength. Both come in a wide range of colors and textures to suit any look…

Test. Trusted. Built To Last.
Safety and security that you can count on. Core offers a number of options for locking hardware. The locking hardware is standard with all our covers, including all the mounting hardware to assure your cover is capable of being installed safely. All covers are also constructed with tie-down straps and fasteners that are triple reinforced. Every Core cover meets or exceeds all safety requirements and carries the ASTM Certificate of Product Compliance.



Environmentally-friendly and energy efficient. Core’s covers are made with 100% recyclable materials to help our earth and your wallet. Every Core Cover comes with a specially designed end-pillow that ensures a perfect seal, which is critical to long-term energy savings. Core’s Vapor Lock Seal plastic is four times more effective in inhibiting moisture absorption than ordinary seals. And, the design and special insulation of our Heat Seal Gasket retains heat and moisture, regardless of the outside temperature. Helps save you money…
