Crawlspace ventilation or not; what is best for insulation?
I am building a workshop. The foundation is being built on bedrock (8 inch stepped foundation concrete wall with PT wood kneewalls to bring it up to floor joist level). The granite bedrock is sloped and therefore has surface water draining from the higher ground when it rains. The perimeter of the foundation (29′ x 20′) will have gravel and weeping tile.
There will be moisture present on the granite surface, regardless of my drainage plans.
My questions are :
1. Do I vent the crawl space?
2. What is the best way to insulate the the floor?
I live Halifax, Nova Scotia, very similar to Northern Maine.
