The Proguard cover adds insulation value to the spa in a region of extreme snow and cold. Proguard covers add approximately two inches (5cm) of insulation above the standard cover. Relax, knowing the spa is safe and the heat is insulated, even in severe weather conditions.
The foam cores are virgin, polystyrene foam tapered from 6″ To 4″ (Platinum Elite & Island Spas) to allow water to run off. Each foam piece is then grooved and fitted with a galvanized steel channel for support along the hinge. Each foam core is then sealed with a 4 mil polyethylene sheeting to help prevent water absorption. Your ProGuard cover will withstand the effects of sun and weather, saving energy with lower total cost of ownership.
