Spray foam in coastal areas?
A friend of mine lives in Connecticut on the water. She took on 1 foot of water in her first floor from hurricane Irene.
The entire first floor is now gutted, where there is a 2 foot crawl space underneath. She is installing spray foam in between the floor joists. Radiant heat will be installed above the spray.
Which type of foam should be used here? If there is another flood and she uses the closed cell, will the house want to float away? Or is the open cell the way to go?
Any and all advice is appreciated here. Thank you.
