An above-ground swimming pool is surrounded by a beautiful wood deck. The addition of a retractable -- or mechanical -- pool cover makes it easier to keep the water warm and clean.
Why would an above-ground pool owner want a retractable cover? For many reasons, including:
- It protects the pool from dirt, mildew and algae growth
- Prevents heat loss by evaporation and radiation
- Keeps children from accidentally falling into the pool
Retractable pool covers are available in automatic and semi-automatic styles, both of which may be operated with a remote control. They are usually made of water-resistant materials like mesh, nylon and various forms of plastic, corrugated fiberglass and foam.
