National Fiber's Cel-Pak Cellulose Insulation is the greenest choice to insulate your home.We make Cel-Pak Cellulose Insulation using over-issue newsprint (daily newspapers that went unpurchased), paper drive paper, and other high-quality recycled paper, all refined to cellulose fiber. Unlike other manufacturers, we hand sort our paper to remove glossy inserts like ads and coupons, twine, metal - anything that isn't good, clean uncoated paper stock, making Cel-Pak the cleanest cellulose insulation you can buy.
Along the way, a natural mineral borate (never ammonium sulfate) is added to the cellulose fiber, which provides our Class A fire rating and resistance to mold and pests.
Cel-Pak is the right choice for homes, commercial structures and municipal buildingsOffering 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 glass fiber. See our Insulation Savings Calculator for more information.
- Cel-Pak has a local recycled content of 82%+. Glass fiber 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 glass fiber and up to 40,000 BTU's/lb for foam insulations.
- We make Cel-Pak right here in New England, which means lower emissions as our insulation travels fewer miles before it gets to your home.
