Pool Cover

Solar blankets, often also called bubble covers, are created from seamed
lengths of dual layer polyethylene material. The polyethylene layers are
bonded together, the top having a flat surface and the underside having
an extruded, multiple bubble, surface. These bubbles, or air cells, aid in
insulation and also allow the cover to float. The core polyethylene
contains additives which color the material as well as strengthening it
and helping to protect it from UV light, the suns heat and from pool
chemicals.
Generally pale in color and translucent, the basic premise of a solar
blanket is to allow the short wave solar energy from the sun’s rays to
penetrate the cover and become trapped within the pool water, thus
increasing the pool water temperature. It has been proven through
scientific study, and years of experience, that the best quality solar
blankets can increase pool temperatures by up to 8OC, thus allowing for
significant savings on heating. Furthermore, a bubble cover makes an
excellent source of heat retention, helps to eliminate debris getting into
the pool and provides the perfect barrier against evaporation.
