Is foam ok under the house?
Our house is on wood piers and beams. There is a substantial space under the house for access to the floor. I want to do spray foam insulation. There is a stone skirt around the house so no major wind blows under the floors. (Another house on the property does not have any skirting and you can see totally under the house.)
Is spray foam insulation a good Idea? Closed or open cell? Do you have an estimate of the cost?
