Abstract
The pool cover is made of multi-layer light weight construction having a translucent top layer to permit sunlight to pass through an opaque bottom layer for absorbing sunlight passing through the transparent layer. In addition, a plurality of pockets are formed in the opaque layer having air encapsulated therein. When in use, the opaque layer becomes heated by sunlight thereby transferring heat by contact to the body of the water in the pool while also blocking light from the body of water to inhibit algae growth. The heated trapped air also serves to conduct heat to the body of water while also acting as a thermal insulation barrier during non-daylight hours. The pool cover may also be turned upside down in use. In other embodiment, all layers may be opaque.
Claims4
A pool cover for covering a body of water in a pool, said cover comprising
- a two-layer construction including
- a first opaque lightweight flexible plastic layer;
- a second opaque lightweight flexible plastic layer secured to and under said first layer whereby said layers block sunlight from entering the body of water to thereby inhibit growth of algae in the body of water;
- and
- at least one of said layers having a plurality of rows of discrete and spaced apart pockets therein facing and sealed relative to the other of said layers to encapsulate air therein to form an insulating barrier over the body of water and to retain heat in and to reduce evaporation from the body of water.
