Below are our Standard cover models. They are 4 inches thick in the middle at the fold and 2 inches thick at the outer edges. The three options presented below differ only in the foam core density. They are made with 1.0, 1.5 or 2.0 pound foam cores. Higher numbers indicate more dense foam which gives the cover more strength and insulation, but are the same thickness. The R-value, or measure of insulation, ranges from R-16.5 to R-25.3 Each can be further customized once selected. |
