Why your Spa Cover is Vitally Important:

After proper sanitization and water balance, your spa cover itself is the single most critical piece of equipment to keep your hot tub water clean, and to keep your energy bill at a reasonable level. Saving money on heating costs means properly insulating your tub, and that is what good insulating spa covers achieve. Heat rises, and just like in your home, most heat loss in a hot tub goes directly up. By sitting just above the steaming water, a well-made hot tub cover provides proper insulation to help trap the heat inside. A problem that arises from all the warm water vapor is that the foam core of a spa cover can eventually become saturated, as water molecules work their way into the millions of tiny hollow spaces inside the foam. When insulating foam becomes wet, it loses almost all of its R-value. While there is no such thing as a totally waterproof hot tub cover, DuraTherm research has developed what we believe is one of the most water-resistant cores in the spa cover industry. Our ZEROtex™ core liner is a special 6 mil thick chemical and water vapor resistant polymer barrier, with heat-welded seams. This material encapsulates the foam cores of our covers. Together with our aquatic-grade foam cores, it is one of the things that makes a long-life DuraTherm spa cover your best choice in insulating spa covers. Our advanced and exclusive Energy Reflex option acts like a heat mirror, saving even more energy. Our marine-grade Enduratex Vinyl and Sunbrella Outdoor Fabric outer covers are both beautiful and ultra durable.
