Which type of insulation is most commonly used in commercial buildings?

The most commonly used type of insulation in commercial buildings is fiberglass insulation. This material is widely utilized due to its favorable properties, such as cost-effectiveness, excellent thermal performance, and ease of installation. Fiberglass insulation is typically available in batts or rolls, which makes it convenient for applications in walls, ceilings, and floors.

Its non-combustible nature also contributes to its popularity, as it helps improve fire safety in commercial spaces. Fiberglass insulation effectively reduces heat transfer, resulting in energy savings and enhanced comfort within the building. Additionally, it is available in various R-values, allowing for flexibility depending on the specific insulation requirements of a building project.

Other insulation types, while useful in certain contexts, are not as prevalent as fiberglass in commercial construction. For example, mineral wool insulation is more often found in applications where sound proofing and fire protection are priorities. Rigid board insulation has specific applications, typically associated with exterior walls or roofs, and spray foam insulation is often used for air sealing and specialized applications but can be more expensive and requires professional installation.
