The best option for exterior spray foam insulation is closed cell. Below is information about the special benefits of closed-cell spray foam and information that will be helpful as you sort through making the right decision for you.
- A higher cost is associated with installing closed-cell spray foam, but the fact that it's permanent and the benefits can easily make that increased initial cost worth it in the long run.
- Professionals like the team at Slagel Insulation must install closed-cell spray foam.
- Spray foam, in general, doesn't work as a temporary insulation. Beings it is a more permanent solution.
- If you have an exposed ceiling or other open space where your spray foam will be visible, it has a smoother finish and a better aesthetic than open-cell.
- Speaking of exposed ceilings, spray foam can also be painted to be cohesive with your overall design.

- Closed-cell spray foam acts as its own vapor barrier, so it's always protecting the right way regardless of the season and how the external and internal air is flowing.
- It has a lower installation threshold temperature than open-cell insulation, but it can't be applied in temps below 20 degrees.
- Once installed, spray foam insulation doesn't settle or shrink but permanently protects and insulates.
- Closed-cell spray foam is the perfect insulation to keep a damp basement dry. It stops moisture from coming through the walls.
- Because it is such an effective barrier, closed-cell spray foam is used to half-life radon. When used with proper crawlspace liners/ vapor barriers, It can block excess radon from entering the building.
- The fully installed closed-cell insulation is stiff and ridged as opposed to open-cell spray foam, which is soft and spongy.
- The hardness and rigidity of closed-cell spray foam actually enhance the strength of the structure in which it is applied.
- Specifically, in pole buildings and barns, closed-cell spray foam reduces the stress on the structure fasteners, preventing future leaks.
- Closed-cell insulation is considerably denser than open-cell, so it weighs about 1.5-2 ounces per square foot.
