Thermal Blanket, Floating, 6' x 6', Light Gray

Our floating thermal blankets are made of a 2 lb. density, 1/4" thick, closed cell foam. Because the foam is 'closed cell' it will not absorb water, so unlike other  blankets it's not necessary to coat the foam with a colored vinyl to keep the water out. The advantages of a simple floating blanket are rather astounding. Most importantly, a floating blanket almost completely eliminates evaporation. By eliminating evaporation a floating cover can reduce the operating costs of a spa in numerous ways.

Heat travels through moist air much quicker than dry air. Reducing the moisture between the water surface and your insulating cover will cut down greatly on heating costs....

Less evaporation = Lower heating costs

 Chlorine, ozone, and to some extent bromine evaporate from the water, simply dissipating into the air and bleaching out the underside of your insulating cover (or eating away the underside of some covers)....

Less evaporation = Lower chemical costs

 Most insulating covers eventually absorb water and get very heavy. Much of this water can come from the rising steam....

Less evaporation = Longer cover life

By eliminating evaporation you'll also find that the chemical balance of your water will remain more stable thereby allowing you to go longer between water changes (oh yeah, water cost money too....more savings).
