Patios are beautiful whether they are left open or are covered to give more protection. Retractable patio covers are either hand rolled or mechanized. The first type is made up of heavy duty canvas and a standard cover is used to cover one side of the patio while this other is attached to the house.
When patios are covered with glass, they are either smoked or made in dark colors to provide UV ray protection. Patio kits are available with or without covers and the price will differ accordingly, also based on material. Certain companies specialize in specific models of patio cover kits.
