When choosing a hot tub, insulation is a crucial consideration. Companies adopt various insulation methods, but we endorse the Northern Exposure Insulation System. This system employs wraparound insulation that envelops the entire hot tub perimeter, effectively trapping heat. It incorporates copper reflectix to redirect heat into the tub and an extra layer of Thinsulate fleece, similar to premium jackets, ensuring enduring insulation performance. Notably, this system reduces energy costs and promotes environmental sustainability through recycled blue jeans and cotton fibers and excels in serviceability. Unlike many hot tubs with inaccessible insulation, our design facilitates easy access to all sides of the tub, simplifying repairs and maintenance. In contrast, alternative methods like partial foam insulation, which only covers the shell and plumbing without filling the cavity, may be less energy-efficient and pose challenges for service due to concealed issues. Full foam insulation, while initially efficient, can become waterlogged over time, resulting in increased weight and difficulty locating leaks for repair. Additionally, repairing a full foam hot tub often involves costly and labor-intensive procedures comparable to working on a car with a welded-shut hood. Therefore, it is crucial to prioritize accessibility and ease of maintenance when purchasing a hot tub to ensure your investment's long-term enjoyment and serviceability.
