RE: My new airplane hanger/ workshop
Yes, that is exactly what we are using, that cement hardi board. My house was actually built 25 years ago and is sided with masonite board but I believe they quickly phased that out.
They have actually finished siding the entire workshop today and it looks fantastic. I will post a few pictures again maybe tommarrow. They should be starting to frame up a carport over the cement slab on the front tommarow. That is if Hurricane Bill or whatever hurricane their on doesnt rain us out.
