A Free Standing Skylight (with optional rolling walls) allows the roof to open up when the walls can stay closed or vice versa. The free standing system can span up to 34′ wide when a 3/12 pitch or greater is used. The perimeter structural steel sub-structure band where the enclosures attach are to be installed by the client. It is often steel with a LVL facing. The skylight systems normally require a custom built motor system(s) designed and built by Roll-A-Cover.
