1.5 lb tapered 4” to 2.5” EPS foam allows water runoff and keeps heat in. These covers are strong yet light weight, making them easy to handle and provide more than adequate insulation at an R Value of 14.3.

Optional 2lb DURA FOAM upgrades are available. Sunstar uses only Virgin Foam to provide you with a more durable, more insulated and more water resistant hot tub and spa cover.
