In kind, meaning size (dimensions and profile), exposure to the weather (the reveal) and composition (in this case, wood). You may consider substitute materials that will be painted for a variety of reasons, including the demands of the building commissioner.

After the whole side of the building is painted, the new flat, smooth materials stand in contrast to the older materials. They were hoping for everything to look new or at least consistent.

Your commission has the ability to limit which materials may be replaced, and what they are replaced with, as long as they comply with the building commissioner's sole requirement that they be fireproof.

This is very frustrating when trying to keep historic materials on buildings. We are trying to push a compromise that will allow public view façades to be original materials and non-public view façades to be non-historic fire rated materials. Has anyone else run into this situation? Any materials other than Hardi Plank that would meet fire safety requirements?
