SpaCap Spa Covers are gigantic leap forward in the technology of Hot Tub Covers. The SpaCap will not break under any snow load or saturate, or blow away in the wind. Your spa water will retain it's heat using less energy, while your Hot Tub Cover stays light weight! Since there is no rigid foam in the SpaCap, our Spa Covers won't saturate, break or warp like typical Hot Tub Covers. Imagine no more heavy or broken Foam Spa Covers. SpaCap Covers will weigh the same and insulate just as effectively in five years as they do the first day they are installed.
