Moving Skylights are :
Flat Moving Skylight
Retractable Skylight
Vault Movable Skylight
Swimming Pool Enclosure
Curb Mounted Skylight

The skylight is designed to sit over the curb like a lid on a box. One of the
benefits of this design is the ability to replace older skylights without
having to re-flash the skylight at the same time. This can greatly reduce
the amount of labour required. Another benefit is the ease to manufacture custom sizes.
