Fiber cement siding is a very sustainable product as it requires very little maintenance and will last a very long time.
- The siding itself is generally sold with a 50 yr guarantee against rot, insects and even coastal salt damage.
- The paint will need to updated every decade or so.
As I look at what makes a product Green, I look at life-span and how it is maintained over that life span, first.Fiber Cement wins that battle over wood in my book.
