Window Wells & Covers (Wholesale) is a subdivision of the Lumber, Plywood, Millwork, and Wood Panels (Wholesale) industry. This industry involves the wholesale distribution of window wells and covers, which are used to provide a safe and secure means of egress from a basement or below-grade living space. Window wells are typically made of metal or plastic and are installed outside of basement windows to allow natural light and ventilation into the space. Window well covers are designed to fit over the window well and provide protection from the elements, as well as prevent debris and animals from entering the well.
