Welcome to our forum.
The same guy that pitched the whole air space insulation thing on the arctics also told me that if it was fully insulated then when the ground was cold it would make the insulation cold and the hot water in the plumbing would have to heat the insulation as well as the tub.. I suppose if I had not taken 2 years of physics at the university I might actually believe that..

May I ask, was this the Montana State fair or North Dakota State fair. I'm a North Dakota spa dealer and didn't know that their was an Arctic dealer in the state so I don't think he's the biggest dealer in the state.
QuoteMay I ask, was this the Montana State fair or North Dakota State fair.

I seriously doubted anything this guy said, but he did mention that he sold some 40 tubs at his state fair in ND..
I went to 3 spa companies yesterday, Arctic was one of them The sales guy told me that they use a layered "fiberglass" underneath the acrylic skin and they are the only ones that use this. This is the reason they do not need the insulation up against the tub. It strong enough. Made sense! Then they have about 4 inches of insulation thatis on the sides of the tubs. R-39 value I think he said. The one issue I really had with Arctic was that they had all wood tubs. No "fake wood" They said that they never sold anything but the real wood. I am not sure I want to stain the Hot Tub every year.
Arctic specifies 3" nominal of polyurethane insulation sprayed on the floor, the inside of the cabinet, and the underside of the shell where it meets the cabinet (this latter insulation also secures hoses where necessary). A typical figure for sprayed polyurethane is R8 per inch, which would give an R-value of this insulation of around R25.The 5/4 cover could have an R value of as high as R40 at the thickest section and R32 at the thinnest section, for an average of about R36.
