Density:

• Expanded polystyrene (EPS) is rated by its weight per cubic foot. For example, 1lb, 1.5 lb, 2 lb, etc. The higher the rating, the stronger the foam.

• Taper is extremely important on spa covers. The more exaggerated the taper, the better the runoff for rain and snow.
•  4"/2" taper

• Here is another place to scrimp (for those with no integrity). Plastic materials used for this can vary. 1mill., 2mil., 3mil., or 4mil. can and have been used. The thicker the material, the longer it will take for the vapor to penetrate and begin to saturate the foam.
• 4mil. plastic, and we hand heat seal it, as other companies use tape.

• The metal reinforcement channels help the foam from warping, and add to the strength of the foam. T-Bars or any other lateral reinforcements will score/weaken the foam, and are not suggested. We know this by previous personal bad experiences. The most important rule that pertains to the metal reinforcement, is to be sure that the metal is not placed in a position where it can rub through the vinyl. The metal should be embedded in the foam and should not be able to be felt from the top or bottom of the cover.
• You cannot feel the metal.

• 4-year
• Months 1-12; No Charge.
• Months 13-48; 1/48 of the current list price of a new cover per each month since the original retail purchase.
