Commercial Structures

Builders and owners of commercial buildings face a distinct set of challenges. National Fiber's Cel-Pak and Nu-Wool insulations are designed to address your real-world concerns.

Cost

Cellulose insulation provides a terrific return on investment. Offering savings up to 40% greater than fiberglass batts in the same installation, an investment in cellulose insulation quickly pays for itself, then provides a lifetime of savings.

Using cellulose insulation allows HVAC systems to be downsized in many cases, versus the same building insulated with fiberglass. Superior insulating value and protection from air infiltration means systems can be sized for performance, not based on conditioned air losses.

Code Compliance

Already in wide use, and accepted by the 2009 revisions of the International Building & International Residential Codes, cellulose insulation is national, regional and local code compliant.

• More than 100 UL approved firewall designs
• Class A fire rating
• ASTM E 84 Smoke Developed Index of zero to 5
• Structurally protective properties such as mold and pest resistance, and airborne moisture management

National Fiber warrants the performance of its Cel-Pak and Nu-Wool insulations for the life of the structure in which they're installed, a warranty that is matched by few others and exceeded by none.
