We are very particular in what material we are installing into the home for its structural lifetime. No second thoughts. We only use the highest quality, all borate forumla cellulose insulation. We use Green Fiber – a professional cellulose for cellulose professionals.
Cellulose Insulation, an Introduction
Would 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 of homes than any other material. You might be tempted to think of cellulose insulation as paper, or even ground-up paper, but in fact it is not. While clean, recycled paper and cardboards form the basis of cellulose insulation, Green Fiber processes ti back into a fibrous state, bearing no resemblance to the original paper. (The same can’t be said for all makers of cellulose insulation, however.)
History of Cellulose Insulation
Cellulose insulation has been around a long time. Thomas Jefferson used a form of cellulose to insulate his estate, Monticello, where construction began in 1769! What we think of today as cellulose insulation has been in wide use since the 1920s, growing dramatically after WWII. The energy crisis of the 1970s and 1980s led to an even greater use of cellulose – and the reputation of cellulose as the insulation that would settle in your walls. That’s no longer the case, as it hasn’t been for a long time. Thanks to dramatic improvements in manufacturing and installation techniques.
What Has Changed?
Green Fiber’s Cel-Pak is, like most things, a much better product than you could buy in the 70s and 80s. First, it’s completely fiberized, which allows for interlocking of the cellulose fibers. Then there’s the equipment and techniques used to install it, which have both been radically improved from the ‘good ole’ days’.
Today, Cel-Pak is “dense-packed” into walls at a density of 3.2-3.5 lbs of material per cubic foot of space, more than twice its settled density. This accomplishes a couple of things. First, the installation process ensures that cavities are completely filled, with no gaps, no voids, no pockets or spaces. Secondly, 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.
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, as well as providing the superior thermal and sound insulation that comes naturally to a cellulose product? There is none, and that is why we choose to use cellulose insulation in our customer’s houses.
