Wait. Doc said if done right it can work. But whats funny is we know full foam works and there are very very few leaks which those not full foaming use as their scare tactic. And we never know if non full foam works. We do know it's cheaper and we do know there is 1 or 2 manufacturers that know how to make it almost as good as full foam. You need some schooling in natural science, sir: Full-foam is just a process left over from antiquity manufacturing processes. In fact, foam cannot physically recover and use waste heat. Neither can foam conduct heat better than free ... air. The Aspen Spas insulation system makes use of a thermal barrier (heat sealed), generated by waste heat rejected from the motors and pumps, in an enclosed air cavity around the tub. It is physically superior to a full-foam system which simply insulates the tub directly. Now, back to cost-efficiency: Air is 1341 times less expensive to heat than water. What doesn't conduct heat are the layers of aluminum and other insulation trapping hot air beneath your Aspen Spa. And if you are heating the air to form an air barrier to stop the super high watt density or BTU's per cubic foot of water, you will automatically save energy, even if you only have 3/8 of an inch of wood and no thermal foil and no foam insulation at all. As stated previously, Aspen Spas have much more thermal sealing than this. So, have fun with your boring, old low-rent fully-foamed spas. Aspen Spas are scientifically designed to be more efficient.

Paper thin........like wearing a T-shirt in the middle of winter Have you actually seen an Aspen Spa or are you making assumptions? I spoke with the owner when I bought mine. He took me back into the factory and showed me the foam used in Aspen Spas. It's a 2# heavyweight size SPF that has an R Factor of about 6 / 1" deep. And MASSIVE heat LOSS. WOW. That's quite the assumption, too. Bearing in mind that R-values are additive, let's talk about the layers of insulation technology surrounding Aspen Spas: Heavy-weight foam, Arctic cabinet wrap, Insulated Fiberglass, etc all come together to make a thermally sealed environment for the spa so that heat loss is minimized. Compare this to the complete lack of evidence that fully-foamed spas have any superior insulation in side-by-side independent testing and what do you have? Misinformation from old-time salespeople praying on lack of consumer knowledge on the subject of hot tubs and insulation. So, good luck repairing the controls on your fully-foamed spa when they inevitably break. Send it right back to the manufacturer to have it cut open, repaired and re-foamed. I bet that's really cost-efficient . You'd have to know almost nothing about natural science to purchase a fully-foamed spa after reading anything about Aspen Spas.
