Select your spa cover 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.


  First pick your insulation thickness.  

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
