The Sunstar Hot Tub Cover starts with the strength of virgin foam cores. We then add further support by adding a galvanized steel C Channel along the length of the hinge. Lastly, we seal the core with Antaeus 2000, our proprietary vapor barrier. This exclusive moisture barrier is more effective than what is typically used.
