ABSTRACT:
The pool cover is made of multi-layer light weight construction having transparent top layers to permit sunlight to pass through, an opaque layer for absorbing sunlight passing through the transparent layers and a reflective layer to transfer heat from the opaque layer into a pool of water. In addition, a plurality of pockets are formed on one of the transparent layers to encapsulate air therein. In one embodiment, the opaque and reflective layers may be incorporated into a single layer with an opaque surface on one side and reflective surface on the other side. Also, the edges of the cover may be sealed so that the entire cover has an encapsulated air layer. The cover can be reversed to place the reflective layer topmost so as to reflect sunlight from the pool, e.g. for short term pool closure. The opaque layer and reflective layer reduce sunlight penetration and thus inhibit algae growth while the insulating layer reduces heat movement either in or out of the water.
