Spa bubble solar covers

Bubble Covers

Solar pool covers, also called bubble covers or solar blankets, are the least expensive and easiest to handle for pool owners. It can also be used in spas. Solar pool covers are made of thick plastic material with UV inhibitors, and they look like bubble packaging material, they float on the surface of the water and are customised to the shape of your swimming pool. The air bubbles that cover the surface of most solar pool covers absorb the sun’s warmth and transfer it to the cooler pool surface. The cover seals in the heat, preventing it from escaping back into the air. This process is most effective when the sun is shining directly on the water. During the night, bubbles act as insulators to hold in heat, but a solar cover does allow some warmth to escape due to basic physics. The outside of the cover becomes cooler than the inside and reverses the thermal collection process. Bubble covers are UV resistant, which means they are better able to withstand damage from ultraviolet radiation. Nevertheless, they rarely last longer than five or six years because the sun does cause them to deteriorate. Bubble covers are lighter in weight than protective pool covers designed to keep people and animals out. Thicker covers are marginally more effective in retaining heat than thinner ones, and they stay in place better during windy conditions, but they are more cumbersome to manoeuvre. Solar pool covers do more than just trap the sun’s heat in a swimming pool. They keep out leaves, dust, and other debris that blow into an uncovered pool, and thus reduce the frequency of skimming and vacuuming chores. They minimize water evaporation and conserve water so that pool owners do not have to add water as often.
