Hardie board siding is a great way to go green when considering upgrading your exterior siding. This type of siding option is fire resistant because it’s comprised of cement and fibers, it’s also rot resistant and the termites don’t want to eat it. What’s also wonderful about Hardie board siding, is that it resembles real traditional wood siding without the crazy maintenance, and it also has the best features of vinyl siding, without the problems commonly associated with it.
