Interior finishing for a four-season porch

Question from Carole: 

What is the best interior finish for a 4 season porch. I have been told that drywall should be avoided. I live in Michigan. 

Jake's answer: 

Carole, 

By a 4 season porch I assume you must be referring to a porch that is opened to the elements. If the porch is not opened to the elements, drywall would work fine. If opened, I suggest a fiber cement product manufactured by James Hardie. You can get lots of information on it at JamesHardie.com These panels come in various sizes and textures. It is a very durable, it is paintable and it even comes in pre-finished panels.
