Pros and Cons of Closed and Open Cell Spray Foam Insulation

Some studies have shown that closed cell spray foam insulation increases the racking strength of walls as much as 300%. Essentially, by using closed cell foam, you are gluing a house together with high R-value insulation that is highly water-resistant. In fact, closed cell spray foam has been used on the top of roof decks of flat roof commercial buildings for more than 50 years since it absorbs almost no water and does not allow moisture vapor to pass through it.
