Having a hot tub outside was not their favor pass time mostly that these folks entertain youngster grandchildren. Everyone wants to be outside and with our trackless retractable enclosure, this client enjoys the sunlight when the weather is in their favor. Exhausting the excessive moisture when the enclosure is open helps with moisture reduction issues that could arise when the enclosure is closed. Its typical of the hot tub industry, a hot tub is just that, a hot bath with moisture to boot. A simply fan often isn't sufficient when you have over 103 degree water surface being attacked by the ambient air sp[ace, but when our Roll-A-Cover enclosure is open? The clean indoor airspace becomes a part of the great outdoor feeling that we all strive for after being cooked up inside of our homes all winter long in New England.
