METHOD OF INSULATING A SPA USING A FLEXIBLE INSULATION BLANKET

摘要

A portable type spa is insulated by a sequence of steps involving initially the preparation of an insulation blanket having a metal foil heat reflective surface on one side with orthogonal dimensions of the blanket sized larger than the orthogonal dimensions of the spa shell. The spa shell is placed on top of the insulation blanket in a preferred method, with the metal foil heat reflective surface facing the exterior of the spa shell. The spa shell foot well is leveled by shims placed between the bottom of the spa shell and the underlying support surface such as a floor. The periphery of the insulation blanket is preferably sandwiched between the underside of a spa rim and a top edge of wood skirt panels surrounding the exterior of the spa shell. The insulation blanket forms a loose bag about the exterior of the spa shell and about plumbing connections on the exterior of the spa shell including warm water circulating tubing projecting outwardly of the spa shell exterior surface. The blanket is locally slit in the vicinity of the projecting tubing to permit passage of the tubing through the blanket and the slits are sealed by taping the tubing about the projecting tubing. Alternatively, the loose bag insulation blanket is fixedly mounted to the interior surface of the wood skirt panels below the top edge of those panels just beneath the connection between the top edge of the skirt panels and the rim of the spa shell.
