Spa Insulation

Bonded Logic Natural Fiber Spa Insulation is made from post consumer recycled denim that is thermally bonded. Natural Fiber Spa Insulation is a Class-1 fire rated material that offers excellent thermal and acoustical performance. Natural Fiber Spa Insulation contains no fiberglass and does not itch or cause skin irritation. It 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 Natural Fiber Spa Insulation a Class-1 Fire Rating.



Use UltraTouch Cotton Fiber Spa Insulation in spa units 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. UltraTouch Cotton Fiber Spa insulation makes maintenance work an efficient and easy affair. Unlike foam options, the insulation panels can be removed and reinstalled quickly, without affecting long-term performance.
