Made thicker than many market alternatives at 16 MIL, the cover is built to resist cracking and to last through repeated use. It’s intended for round or nearly square hot tubs, inflatable spas, and small above- or in-ground pools; the sheet can also be trimmed to fit irregular shapes.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this cover keep my hot tub warmer between uses?\u003c\/h3\u003e\n\n\u003cp\u003eThe bubble layer forms an insulating barrier on top of the water, slowing heat escape and minimizing surface evaporation. By floating directly on the water with the bubbles facing down, the cover reduces convective and radiative heat losses so your heater runs less often.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e16 MIL material thickness increases thermal resistance versus thinner covers\u003c\/li\u003e\n  \u003cli\u003eBubbles trap air pockets that act as insulation at the water line\u003c\/li\u003e\n  \u003cli\u003eReduces water evaporation up to approximately 95% when used correctly\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat size tub fits this 5.4 x 5.4 ft blanket and can I trim it?\u003c\/h3\u003e\n\n\u003cp\u003eThis square blanket is sized for small hot tubs that measure close to 5.4 x 5.4 ft internally or for round tubs with similar surface area.
