The World’s Finest Hot Tub Cover: Castcore®
The Worlds Longest Lasting Hot Tub Cover.
To top it all off, we offer an optional upgraded cover that is unlike any other in the industry. The Castcore® Mylovac cover starts with foam twice as dense as the industry average. We also insert a metal “C” channel into the foam centers. This creates a cover capable of supporting thousands of pounds of weight. Never worry about snow loads or kid loads again. We then wrap these inserts in a metal/poly bag (similar to a coffee bag). This bag is then vacuumed and heat sealed. This technology is the only system that is capable of completely keeping moisture off of your cover inserts. Wet and heavy covers result in constantly increasing running costs as well as regular cover replacement. Longer wind flaps, locking straps, carry handles, and an insulating baffle along the entire seam, finish off the best cover in the industry.
This cover will save you thousands over the life of owning your spa.

Great video but for the time I can’t afford to replace.
Hot tub is winterised as cover cores are in my conservatory drying out very slowly.
For a 42″ x 85″ Coyote cover 80mm to 60mm taper about 6 years old – What should be the dry weight?
They currently weigh 56lbs and 62lbs (when first removed 1 month ago weighed 67ibs & 77lbs!)

Hi Michael, look for an email in reply to this.
Were you aware you can buy the foam inserts on their own, for much less than the entire cover?
I quick chat with one of our UK team might answer lots of questions for you: 0800 862 0263
