Open-cell or closed-cell spray foam insulation in Maryland
Our experts will help you choose the best spray foam insulation for your needs.
With energy costs on the rise, people are paying more for heating and cooling. Maintaining comfortable home temperatures demands electricity, gas, and oil to run HVAC equipment, including furnaces, boilers, heat pumps, and air conditioners.
Most homeowners understand that improving home insulation is a surefire way to cut HCAV costs — that's where spray foam comes in. Foam insulation contractors fill spaces between studs, joists, and rafters to effectively seal the home.

Can spray foam insulation improve home energy performance?
We help homeowners choose the best insulation for their homes. But what is better, closed-cell or open-cell foam insulation? Many people are confused about the differences between open-cell foam and closed-cell foam:
More about open-cell foam insulation:
- Lower R-value & higher permeability: Open-cell foam is made up of tiny bubbles that are interconnected. The bubbles hold air, which provides insulation value — typically between R-3.5 and R-4 per in.
- Air sealing value: Open-cell foam expands to fill gaps and cracks. But instead of curing to a hard, smooth-surfaced mass, open-cell foam has a spongier feel.
- Absorbs moisture: Open-cell foam will absorb moisture and lose R-value when wet, so it is not advisable to use open-cell foam in damp rooms. It can be sprayed between rafters or studs, but won't provide much insulation value in a confined space.
- Pricey installation: Open-cell foam is usually less expensive to install than closed-cell foam.
More about closed-cell foam insulation:
- Stronger airtight barrier: Closed-cell foam provides a moisture resistant barrier, a harder finish, and higher R-value
- Adaptable application: Canned foam is a closed-cell foam that comes in "single-component" form. The closed-cell foam that is used on large-scale spray foam jobs is known as "two-component" foam or polyurethane foam.
- Preferred insulation: Closed-cell insulation is often preferred for home insulation as it offers higher R-value — between R-6 and R-7.1 per in. The ability to block moisture while also providing air sealing and high insulation value is an advantage in many applications.
