The Sunstar Hot Tub Cover takes the strength of Virgin Dura Foam cores with an R value of 14.3 and tapers the foam from 4" to 2.5" to allow accumulated water to easily run off. We then strengthen the channel hinge with 20 gauge galvanized steel and add a full length heat seal gasket (optional on all hinged covers) with the Antaeus 2000™ Vapor heat seal for the strongest heat seal in the industry.

Sunstar 2 Pound EPS Upgrade

For a minimal up charge you can add to the insulating factor of your spa cover with 2 lb. EPS foam giving you an even higher R value. This is a great option when concerned with the environment and rising energy costs.

Sunstar Atlas Hot Tub Cover

The Atlas hot tub cover is fitted with strong and durable marine grade vinyl constructed with 1500/hr tested UV and mildew inhibitors dramatically extending the life of the cover. The Atlas' foam tapers from 5" to 4" giving you an R value of 19.8. All of our hot tub and spa covers come standard with a low profile drain grommet and are ASTM and UL safety classified for your family’s protection.

Sunstar Atlas spa covers can hold up to 1,000 lbs of static weight, and are highly recommended for any location with harsh winter climates.
