Mendocino101:
I have noticed something that I hope some of the Industry guys here might be able to answer...I have noticed that “most” of the older and without a getting into a big debate, commonly respected Manufactures...Hot Springs, Sundance, Marquis, Beachcomber make full foam tubs.... while many of the newer or smaller makers use the thermo design...without getting into who is better.... I believe each have their own merits as well cons.... is it easier to start up and build this way...(thermo) I know when I toured both types of factory’s... while in the full foam makers I was told while watching the foam being installed that it was the most difficult part of the manufacturing process....

Wisoki:
I don't understand whats so dificult. The spa is upside down, the cabinet is on. The equipment area is protected. ready aim fire, what's so difficult? Free flow is a start up and they are full foamed. With respect to thermopane style, if you only foam the shell and not the plumbing, sure it's a little easier, but if you foam your plumbing also, there seems to be a lot more care needs to be taken so your tub doesn't become full foam. I would guess it is solely the prefrence of the specific manufacturer weather or not they full foam.

ZzTop:
Aside for the R value issue the most important thing regarding thermopane is how well the plumbing pipes are foamed around where they are attached to the jet fittings to help support them.

drb:
If you go with a full foam spa process, you have to be careful about placing the pumps in one certain area.  Most of the multi-pump non-foam spas have pumps all over under the spa.  The non-foam design thus also gives you a little more room to "un-kink" the plumbing coming off the pumps.

dpgtech:
Some respectable companys use thermo pane design.  Coleman has been using the thermo pane design for 15+ years.  so not just start up companies use the design. In terms of which is more diffucult to do they both have their techniques to make the process as efficient as possible.
