I have a room that extends above an alleyway in a Victorian terrace house. In the alleyway the bottom of the joists that span it are exposed. I would like to place some form of boarding up to cover these. The alleyway is open at each end, but does not receive direct rain.
What material I am best using; I would like it to be moisture resistant and, to some extent, fire resistant.
