Below are the best options to cover your design pool.
Rigid flat cover
The swimming pool enclosure is made from a retractable cover. It can be made of synthetic timber, aluminum , or galvanized iron. It is available in manual or motorized versions.
You have two options for opening the pool cover: longitudinal opening where parts of the cover are retained along the pool's sides or both; or cross-opening in which the cover is located at one end.
Swimming enclosure with removable rigid cover
This is a type a swimming pool enclosure that acts as a lid and on which there is a garden. When the pool is covered, the cover is moved to the side so that the garden can be seen to one side.
It is also known as a Mobile Garden. You also have the option of opening the cover on both sides to create a garden along each side.
Mansard Roof
This enclosure style has a flat top and sides that slope to meet the house and wall panels. Because of its open design, a mansard roof feels spacious. This is also the most common enclosure style.
