Premium Materials = Premium Spa Cover Premium Materials = Premium Spa Cover
A spa cover is the sum of its parts. If you use good materials in the manufacture of a spa cover, you will get a good spa cover. In over 20 years of spa cover manufacturing, our manufacturer has found the finest materials available to build our covers. From the UV-treated thread to the industrial zippers and the premium SpaLux vinyl to the virgin EPS foam, Thermal Guardian premium spa covers are manufactured to the highest quality standard.

Over 20 Years of Spa Cover Experience Premium Materials + Superior Technology + Quality Craftsmanship
The recipe for a great, long-lasting spa cover is simple. You start with Premium Materials. You acquire Superior Technology and assemble a team of experienced Quality Craftsmen and women who are paid to care what the product looks like. The watertight vapor barrier is sealed with a 9' long computer-controlled impulse sealer that makes a seal second to none. It is drastically better than foam cores sealed with small, undependable hand sealers. Our covers' patterns are cut by Otto. That would be the computerized cutter that doesn't make a mistake within a 1/1000th of an inch. There aren't computers that sew the cover, but even better a team of seamstresses tailor your cover to the fit you require.

Best seal in the industry
