Cellulose Insulation (National Fiber Cel-Pak)

Offering proven energy savings, the highest recycled content and the lowest embodied energy (the amount of energy it takes to manufacture) of any insulation choice, National Fiber's Cel-Pak is not only a great choice, it's the greenest choice, too.

• Cel-Pak saves you more on your heating and cooling bills - up to 40% more than fiberglass. See our Insulation Savings Calculator for more information.
• Cel-Pak has a local recycled content of 82%+. Fiberglass has less than 35%, sprayed foam insulations nearly zero.
• Cel-Pak takes 750 BTU's per pound to manufacture, vs. 12,000 BTU's/lb for fiberglass and up to 40,000 BTU's/lb for foam insulations.
• Cel-Pak is made right here in New England, which means lower emissions as our insulation travels fewer miles before it gets to your home or job.
