Skylights that open and close

Operable skylights and roof windows are able to open and close, either manually or by an electronic system. They allow for ventilation and for fresh air to circulate. Advanced tubular skylights and sun tunnels can be controlled to dim or brighten the natural light in your rooms and can filter light to areas where windows would be useless. Operable skylights have the option of electric blinds (or skyblinds), which are operated by a remote or wall switch.
