Professional Cellulose for Cellulose Professionals


As a contractor, you're used to dealing with construction details that your customers may never see, like the insulation. We think it makes sense to offer your clients the option to upgrade to National Fiber's Cel-Pak cellulose. Here's why:
  • Demand for energy efficient homes grows every day. Cellulose can reduce air infiltration 38%1 or more vs. a glass fiber insulated home2,3, and that shows your clients you're energy smart, and thinking of their long term cost of ownership. Whether you're building a new building, or retrofitting an existing one, check out our handy Insulation Savings Calculator to help demonstrate to your clients just how much cellulose might save them.

  • Your reputation depends, in part, on how well your projects perform. A drafty building that wastes energy doesn't make for happy clients, and unhappy clients don't make good references. Dense-packed or spray applied cellulose in the enclosed cavities, free of voids and gaps, reduces energy use year-round, eliminates drafts, and keeps interior building surfaces warm, helping to guard against moisture and durability issues. Cellulose insulation also reduces sound transmission and can help improve fire safety by slowing the spread of fire. Loose-fill cellulose in the attic isolates the living area from the attic and, combined with effective air sealing, prevents moisture issues and ice dams.

  • Callbacks are every contractor's worst nightmare. Cellulose handles tricky assemblies, like unvented cathedral ceilings or insulating around skylights, like a dream. No air infiltration means no ice dams, and that means no callbacks down the road.

  • Happier crews. Ever had anyone on your crew volunteer to install glass fiber? We didn't think so. You can sub out your cellulose installation to an experienced installer, or we can teach you how to do your own, as well as provide equipment and ongoing field support and training.

  • Safety and comfort. Cel-Pak insulated homes offer excellent thermal performance, fire resistance and sound attenuation.

  • The environment. Being green is important. There's no commonly used insulation that can beat Cel-Pak's 83% recycled content. A National Resources Defense Council report4 says, "The fiberglass industry averages 35% recycled glass…". We produce Cel-Pak with pride in Massachusetts, and source our paper as locally as possible. We work hard to be environmentally responsible, so you can be, too.
