STORMWATER CHAMBERS THERMOFORMED FROM COEXTRUDED SHEET MATERIAL
A thermoformed arch-shaped plastic storm water chamber (10) has an exterior surface formed of first layer (202) having an increased reflectance additive and an interior surface formed of a second layer (204). The increased reflectance additive is a pigment (other than a black pigment) or may be a mineral component. Optionally, a supplemental ultraviolet and/or antioxidant protection additive is also provided in the first layer. The thickness of the first layer is less than the thickness of the second layer, optionally in a 20%/80% of total thickness ratio. The two layers may be made from the same or different HDPE or blends thereof.
