Hot tub cover foam thickness

Foam core thickness and density determine the insulating value of the cover. Foam density also determines the strength and load bearing, as well as cover durability.

R-VALUES AND INSULATION

Insulation is rated in terms of thermal resistance, called R-value, which indicates the resistance to heat flow. The higher the R-value, the greater effectiveness of the insulation. Put simply R-Values are a materials ability to resist the conduction of heat flow through a solid. A hot tub has an R-value that represents the insulation in the shell and floor. The higher the R-Value, the slower heat passes through the shell to the outside. Ensuring your hot tub has a good R-value will help greatly in conserving energy consumption.

An important factor in determining the R-value is the thickness of the foam. The R-value is determined by multiplying the R-value times the thickness. This is why thicker covers insulate better.
