Abstract
A hot tub cover consists of an impermeable exterior shell and at least one multilayered insulative and structural core. Each multilayered insulative and structural core may further have multiple core layers layered adjacent to each other in various configurations, providing superior protection from heat losses from within the hot tub as well as structural strength and durability.
