I have seen there are several Foam density for a hot tub covers. I wonder what should a good foam density be.
Does it make a big difference? For instance, does it help to warm up the hot tub faster?

It will give you better insulation and strength on a 2 pound foam density compared to a 1.5 or 1 pound foam based on the same thickness of the foam core. So it helps maintain the temperature in the spa between heating cycles.
