An Introduction to Cellulose Insulation
A Little History About Cellulose
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 1920’s, growing dramatically after WWII. The energy crisis of the 1970’s and 1980’s led to even greater use of cellulose – and the reputation of cellulose as an insulation that would settle in your walls. That’s no longer the case, and it hasn’t been for a long time, thanks to dramatic improvements in manufacturing and installation techniques.
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, that’s processed back to a fibrous state, bearing no resemblance to the original paper.
