Hot Tub and Portable Spa Insulation - Spend a Few Save a Bunch

Full foam closed cell insulation reduces heating cost by up to 35% versus dead air space spa’s. Increased
durability, quieter, more like a Thermos © as far as heat retention and less expensive to operate. We’ve heard
every argument about this one, so save your breath folks. Full foam is the best insulation available, period. Be
sure to ask and see it. Your spa dealer will be glad to show you.

Less noise to talk over

Full foam insulation consists of filling the area between the shell and cabinet sub floor completely with a thick
layer of solid, rigid foam. Over 70% of the hot tubs manufactured today use this method of insulation because
it is an excellent way to insulate as well as support the hot tub shell. Full foam insulation will keep heating
costs to a minimum whether you use the spa indoors or out. While some spas feature full foam insulation, it is
often a low-density, open-cell packaging type foam which doesn't provide an adequate amount of insulation,
and can result in higher heating costs.

However, multi-layers of high-density, closed-cell polyurethane foam (typically the same material used to
insulate commercial freezers), result in low operating costs. "Closed cell" foam generally provides greater
efficiency because it cannot absorb water.

Also, be sure to ask the dealer or manufacturer for a
documented estimated monthly operating cost. Multiply
the average monthly power usage by the electricity cost
quoted by your power company to estimate the impact a
spa will have on your energy bill. Along with the insulation
advantages of urethane, noise cancellation from a fully
foamed hot tub is a valuable advantage to the end user. In
addition, there is the added rigidity and structural aid that
is given to the spa due to the attachment of the spa shell to
the spa exterior during the filling process
