OH, so the thermopane companies are strictly manual labor, a guy with a foam gun taking his best shot?! ERRRRRRR wrong answer! More precision is nesessary in the thermopane spas so as not to over fill the cabinet and accidentaly becoming a full foam spa. None-the-less, both forms of insulation work just fine. If the customer likes the thermo idea, buy it, if they like the full foam idea buy that. If these start ups put zero insulation on the spa shell and only a 1-1/2 inch cut piece of styrofoam on the cabinet, then I would think it's a cost issue. Otherwise, spas cost very similar prices to produce.
And therein lies the answer to the original question?
It's easier to start up and build thermo because such a mechanized and computerized process is not necessary? Brutus just connects the thermo panels together??
