Will Cellulose insulation settle resulting in loss of original R-Value?

No all loose-fill insulation products will settle over time. However we make sure that we do our installations in accordance with the cellulose insulation coverage charts from the manufacturer. When installed properly in accordance with the coverage chart, cellulose insulation will not settle below the intended R-Value.

Is cellulose insulation is more flammable than other products because it’s made from paper?

No cellulose Insulation has a Class 1 Fire rating. It is treated with fire retardants to meet or exceed all legislated fire safety requirements. Some products have even qualified two and three hour firewall designs.

Does damp spray Cellulose Insulation that is applied wet in walls increasing the likelihood of mold and mildew?

Not at all, this type of application is common in new construction where a small amount of water is added for increased bonding to the sheathing. The moisture content, when installed correctly, dissipates quickly, typically resulting in moisture content at or below wood framing members. Any trace moisture in the insulation will pass through the drywall after it is installed, similar to moisture in wood wall studs.

Is cellulose insulation is more expensive?

Cellulose Insulation in walls will typically be more expensive than fiberglass batts due to higher installation costs. The difference is easily overcompensated in the greater savings on energy costs by using Cellulose Insulation. Blown in Cellulose and blown in fiberglass insulations are comparably priced. Cellulose Insulation is less expensive than foam.

As cellulose is made of paper will be more susceptible to humidity and mold?

This is simply not true. Cellulose Insulation is no more subject to mold contamination than any other building material. Published studies indicate that the hygroscopic nature of cellulose insulation results in superior moisture handling characteristics.

How can Cellulose Insulation be Green as it results in deforestation because it uses wood from trees?

Cellulose Insulation is made from recycled paper, not material from newly cut trees. In fact, Cellulose Insulation, with almost 85% recycled paper content, actually diverts almost a million tons of waste paper from landfills annually.
