The covers foam core is the "back bone" of every spa cover. Not only is it the main insulating factor, it also provides the strength needed for years of use. One of the important features of our foam is that it's a virgin foam, rather than recycled. While both may have the same insulating value, recycled foam doesn't have nearly the strength as the virgin foam we use.
The two important aspects of the foam are the thickness and the density of the foam. Each effects the overall strength and insulating ability of the spa cover. We offer a variety of thickness and densities to suit every need.

The most popular covers are the Deluxe Standard and the Extreme Standard. The foam core of the Deluxe Standard spa covers are a 1.5 pound density, metal reinforced, EPS (expanded polystyrene) foam , tapered from 4" to 2". The foam core of the Extreme Standard spa covers are a 1 pound density, metal reinforced, EPS (expanded polystyrene) foam , tapered from 6" to 4". The taper is necessary to allow accumulated water to easily run off. Many older, and some cheap covers are made of a flat foam which will allow water to puddle,causing the cover to sag, allowing more water to puddle, eventually breaking the cover.
Foam density refers to the weight of a cubic foot of foam. A 1.5 lb. density is generally the ideal for a 4" thick cover. It has excellent strength and insulating ability, yet is light enough to maneuver on and off your spa. Lesser densities are NOT advised for a cover of this thickness due to their lack of strength. With our 6" thick cover, a 1 pound density is more than enough. It provide almost 50% more insulation value over our 4" cover, is stronger, yet is the same weight. Higher foam densities have additional strength, but only slightly more insulating ability. One of the many options we offer is upgrading to a higher density foam if additional strength is needed.
Please note, these measurements are the true measurement of the foam itself. It is not a nominal measurement, nor does it include the thickness of the vinyl or vapor wrap (you'd be surprised how many others don't use a "true" measurement, and add in thickness of the other materials used).
