Open Cell Spray Foam vs Closed Cell Cost
The cost to insulate an entire existing home with spray foam varies by factors such as the size of the insulated area, difficulty of the job, thickness of foam applied, and type of foam used.
Let’s take an apples-to-apples look at a cost comparison between open cell and closed cell spray foam.
Say you have a 1,000-square-foot attic that you’d like to get spray foamed. The cost for 7-inches of open cell, including removal of old insulation, would be in the ball park of $5,250. Now if you were to install closed cell into the same attic at the same depth, it would cost upwards of $10,350. It’s important to note here that for closed cell spray foam we would normally recommend 5-inches of the product which would come in around $8,350.
Here’s another open cell spray foam vs closed cell cost comparison using a crawl space.
To install open cell spray foam on the walls of an average 800-square-foot crawl space at 3-inches would cost around $2,350. For the same crawl space installing the same depth of closed cell spray foam would run $3,700, but we would normally recommend 2-inches of the material which would be in the $2,900 range.
Installation of open cell spray foam is much easier and the foam itself is less expensive to produce, therefore the cost of open cell is less expensive. Closed cell spray foam, besides being more expensive to make, must be applied in thinner coats, often requiring several passes which can drive up installation time and cost.
