We are currently building a small office in one corner of our warehouse. Its about 12' x 12' with built against an outside window with security bars. There will be an FD30 fire door- the roof will be made of wood covered with plaster board. A window to the warehouse will also be provided. The roof of the office will be about 40' from the roof of the warehouse.

There is a final exit about 30' from the office.

As we are having the sprinklers up-graded there will be a head in the office.

The office will have two occupants with pc's, printer and a wall mounted heater.

Do we need to upgrade the window and roof to match the door?

Thanks

Andy
