Sustainablue Spa Insulation

Zen Hot Tubs™ are made with Sustainablue Spa Insulation which is made from post consumer recycled denim that is thermally bonded. This Natural Fiber Spa Insulation contains no fiberglass and does not itch or cause skin irritation. Sustainablue is treated with a non-toxic solution that actively inhibits the growth of mold, mildew, bacteria and fungi. This same treatment also acts as an excellent fire retardant, giving our insulation a Class-1 Fire Rating. Sustainablue insulation makes maintenance work easy and efficient. Unlike foam options, the insulation panels can be removed and reinstalled quickly, without affecting long-term performance.

Energy Efficient: Sustainablue insulation comes with a foil backing used to reflect radiant heat from pumps and equipment back into the spa, where it can be absorbed into the plumbing. Heating efficiency will be improved by raising and maintaining water temperatures with less energy required. These factors lead to overall lower energy use and savings.
