What Is Cellulose Insulation
THERMAL INSULATION COMPRISED OF RECYCLED MATERIAL
Cellulose insulation is made from newspaper, cardboard, straw, sawdust, or cotton.
Cellulose insulation is one of the earliest forms of insulation, but early on it was used infrequently due to its composition being considered very flammable.
Today's cellulose insulation is safe and environmentally friendly. It is made from recycled paper products and treated with boron to make it fire retardant.
How Cellulose Insulation Works
ORGANIC-BASED THERMAL INSULATION
Cellulose insulation is made from materials with low thermal conductivity.
As heat tries to pass from one surface to another, cellulose insulation slows down the rate of conductive heat transfer.
The high-density composition of cellulose insulation provides additional coverage against air infiltration and convectional heat transfer.
Because cellulose insulation is made from recycled paper-based materials, it has to be treated with boric acid to help prevent flammability, decay, and mildew;
Where To Use Cellulose Insulation
BATTS, DENSE-PACK, WET-SPRAY, & LOOSEFILL
Cellulose Batts come in pre-cut lengths designed to fit conventional wall framing cavities.
Dense-Pack Cellulose is pneumatically injected into the framed wall cavities to update framed wall insulation.
Wet-Spray Cellulose is mixed with a bonding agent that allows it to stick to the surface of the vertical wall cavities where it is sprayed.
Loosefill Cellulose insulation is designed to be blown (or sprayed) into place. Loosefill cellulose insulation is ideal for attic floors.
Cellulose Insulation Wellness & Safety
Treated to provide fire resistance, achieving a Class A fire-rated building material classification (per ASTM E 84).
Non-Combustible
Cellulose insulation is made from recycled materials and manufactured without adding formaldehyde or asbestos.
Eco Friendly
Why Choose Cellulose Insulation?
PROS
CONS
Cellulose insulation is produced using recycled waste materials, making it a good option for environmentally conscious consumers.
The high-density of cellulose can reduce air infiltration better than other forms of loosefill insulation.
Wet-Spray cellulose insulation is an effective, and less expensive alternative to spray foam insulation for insulating wall cavities.
Cellulose insulation has to be treated with boric acid to prevent flammability, decay, and mildew; prolonged exposure to moisture can deteriorate the boric acid, leading to unsafe conditions.
Cellulose insulation can produce 20%-60% more dust than other forms of loosefill insulation.
The high density of cellulose can cause it to settle by up to 20% from its installed R-Value.
Cellulose insulation is a naturally heavy material with a high moisture absorbency rating; over time, the increased heaviness of cellulose insulation can lead to the sagging of ceiling areas.
Our Reccomendation For Cellulose Insulation
Cellulose insulation is environmentally safe and inexpensive. Cellulose insulation can be an excellent choice for environmentally conscious consumers, and for select retrofitting and new construction projects. For attic floors, there are other environmentally friendly forms of insulation that do not have some of the negative features of cellulose insulation. Our primary consideration of cellulose insulation is for wall cavity applications.
