My home inNew Orleans is on raised piers and am trying to decide whether to use open or closed cell foam on my exterior walls. Advice??Pls!
House is 1oo + years old with no insulation at all -- doing renovations and replacing plaster walls with sheet rock
I am assuming you will be fixing any bad electric, flashing & moisture issues... Being that close to water with high humidity I would lean towards Closed Cell - with that, if your wall assembly is properly done you could use open cell Quick word - the wall assembly should be done properly for both but it is more important with open cell. You may also wish to look into a rain screed detail, that will help eliminate a ton of possible issues down the road
