Thermoshield Spa Covers

Core offers the greatest selection of spa covers.  Our ability to manufacture covers for any size and style of spa ensures  the perfect fit. No cover leaves our facility without undergoing stringent quality assurance and all dealers can order and track their covers through our online ordering system.  We offer you the peace-of-mind in knowing that when your cover delivers to you, you’ll have received the best. ​ 

Every Core cover is constructed with the best available materials; including, marine-grade vinyl  that's treated with mildew and UV inhibitors, high efficiency  EPS foam to provide a stronger and more energy efficient cover, and scientifically formulated plastic that's far more resistant to water vapor transmission than ordinary plastic. The most advanced machines are used to cut all materials for perfect adherence to specifications, and each cover is constructed with double stitching and 40-point reinforcement.  During the entire process, every cover is supervised by a highly trained Core craftsman.

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.
