Cellulose Insulation

nfInstallPic8.jpgWould it surprise you to learn that cellulose is the most common building material in the world? It shouldn't, because wood is cellulose, and you'll find more wood used in construction than any other material. You might be tempted to think of cellulose insulation as paper, or even ground-up paper, but in fact it's not. While clean, recycled paper and cardboards form the basis of cellulose insulation, National Fiber processes it back to a fibrous state, bearing no resemblance to the original paper. (The same can't be said for all makers of cellulose insulation, however.)

National Fiber's Cel-Pak is, like most things, a much better product than you could buy in the 1970's. First, it's completely fiberized, which allows for interlocking of the cellulose fibers. Then there's the equipment and techniques used to install it - both radically improved from the 'good old days'.

Today, Cel-Pak is 'dense-packed' in walls at a density of 3.2 - 3.5 lbs of material per cubic foot of space, or more than twice its settled density. This does a couple of things. First, the installation process ensures that cavities are completely filled - no gaps, no voids, no pockets or spaces.

Second, using 3.5 lbs. of material per cubic foot ensures that the material is under slight pressure in the wall cavity. It simply can't settle, because there is no room for it to settle. (Those displays you see at trade and home shows showing cellulose blowing around in a box? They're designed to trick you, using far less material than is installed in the field, so don't be fooled.)

The bottom line

Cellulose has improved in quality and sophistication over time, and it now provides exceptional resistance to fire, moisture, mold, and vermin. What other insulation can claim these benefits and also provide the superior thermal and sound insulation that comes naturally to cellulose?

"Money's no object." Have you ever used that phrase when you were building a new home or renovating your current home? We didn't think so, and neither do most people, so let's get something out of the way up front:

Cellulose insulation isn't the least expensive insulation you can buy.

But here's what you really need to know. Cellulose insulation, while it costs a bit more when you install it, is going to save you more money every year on energy costs. But don't take our word for it.

The University of Colorado School of Architecture and Planning built two identical buildings to compare fiber glass insulation with cellulose insulation. They concluded, "The cellulose insulation alone tightened Building A approximately 38% more than fiber glass tightened Building B."

Saving money is a good thing, but it's far from the only reason to insulate with cellulose.

We'll give you a quick rundown here:

Our products are loose blown in attics and dense-packed in wall and ceiling cavities, where they resist air infiltration very well. The result is no drafts and lower energy usage. Cellulose also reduces noise far better than other insulations.

Safety

Our Cel-Pak and Nu-Wool products are Class A fire rated, which means they resist fire and can slow its progress, allowing more time to escape and limiting fire damage. Other insulation products melt, which may allow a fire to spread more quickly, or produce toxic smoke, and smoke is especially hazardous to occupants in the event of a fire.

Dense-packed cellulose doesn't settle, period, so once installed it's doing its job for the life of the building. And one of the jobs it does is moisture management. The hygroscopic (moisture absorbing) properties and the borates in our products help prevent moisture from indoor and outdoor sources from accumulating and causing damage.

It's Green

Cel-Pak and Nu-Wool are made with 83% recycled content. No other commonly used insulation even comes close. National Fiber is the only manufacturer of insulation in New England, so our materials and products travel fewer miles, reducing the impact on the environment.

When it comes to your choice in insulation, there's really no contest. There's Cel-Pak and then there's everything else. Cel-Pak cellulose insulation - the advantages are undeniable.
