Solar Blankets, often referred to as bubble covers are an efficient, cost effective way of retaining heat in your swimming pool water. Solar covers use an insulating technique similar to that of double glazing and help prevent heat loss through evaporation which accounts for 85% of all pool water heat loss. The new Geo-Bubble technology has been specifically created to combat the attacks of UV and pool chemicals and has converted the limitations of a traditional bubble to great advantage. Sharp corners which were once an area of high stress have been replaced by a smoother, more uniform shape and a thickness of material (50% thicker that standard bubble) which considerably increases the bubbles resistance to attack from the water. On the surface, improved UV additives, stabilisers and antioxidants have added to the covers overall durability and within the bubble a larger cavity offers more room for air expansion.
