Hi:
Being new to this forum, this may be an old question.
I'm thinking of siding a new house with cement-fiber siding. The house will have full insulation (closed cell foam) surrounding and under the basement foundation. Local codes say no earth backfill should be nearer to house siding than 8 inches to keep moisture from rotting the wood frame and for termite protection. However, this plastic foam does not like sunlight.
Covering that foam insulation used to be done with the old asbestos cement board and it worked. I'd like to start a siding job at the backfill elevation and continue up the walls, assuming the cement-fiber siding will not take on water and wick it up to the wood, etc.
Are there tests for moisture absorption or is this so cut and dried these days that there is "no problem"?
