Comprehensive Commercial Insulation Options


Fiberglass batt insulation is available in widths suited to standard spacing of wall studs, and ceiling or floor joists. Blown-in fiberglass insulation can be installed in nearly any space. It can be dense packed into closed cavities.

Spray Foam Insulation

Spray foam insulation is a two-in-one product, insulating and air sealing in one step. Our commercial insulation contractors install both open-cell spray foam and closed-cell spray foam.

Open-cell spray foam has a density of 0.5 pounds per cubic foot. It is made up of cells of foam that are not completely closed. The cells are broken and air fills all the “open” space inside the material. Open-cell spray foam insulation has an R-value of 3.4 to 4.5 per inch.

Closed-cell spray foam has a density of 2.0 pounds per cubic foot. The cells are closed and packed tightly together. They are filled with gas that helps the foam rise and expand. Closed-cell foam is very dense, and therefore has greater insulating properties and can also increase building strength during high winds and storms. Closed-cell spray foam insulation has an R-value of 5.4 to 7.2 per inch.

Hybrid insulation installation brings together two of the most popular insulators: spray foam insulation and fiberglass commercial batt insulation. This technique is used in wall cavities in the following two-step procedure. First, one inch of closed-cell spray foam insulation is applied to the target area. Once the closed-cell spray foam is in place, fiberglass batts are placed over the top of the foam. The result is an insulation solution that provides all the benefits of air sealing with spray foam insulation at a lower price point than full foam.

Mineral Wool

Mineral wool insulation offers the R-value found in other commercial insulation products and is fire-resistant. Made of inorganic fibers derived from basalt, a volcanic rock, these materials are naturally fire-resistant. It can reduce the spread of a fire and provides valuable extra minutes to save people and property, and reduce environmental damage.
