Cellulose insulation is good for your home and environment
Cellulose insulation has a functional lifetime of more than 50 years!
Blown in cellulose insulation is produced primarily from post-consumer wood pulp (recycled newspapers), typically accounting for roughly 85 % of the insulation by weight.
Cellulose insulation is treated with fire-retardant. Borates and boric acid are used most commonly and account for the other 15 % of the cellulose insulation by weight.

Green Attic Insulation Can Help!
Mold Resistance
Cellulose significantly decreases the risk of mold even beginning to form. Thanks to its chemical treatment, mold doesn't grow on cellulose insulation. Cellulose insulation absorbs moisture, redistributes it and lets the attic/wall/ceiling dry in a controlled manner.
Pest control
Cellulose insulation is pest-resistant insulation that is a great addition to your pest prevention plan. This insulation works on most common household pests such as cockroaches, ants, beetles, earwigs, silverfish, termites, etc.
Air / Vapor Barrier
Air infiltration is almost as important as R-value in the thermal performance of a building. Infiltration of unconditioned ambient air means that heating and cooling systems must expend more energy to compensate for the infiltration.
Sound Control
Cellulose provides very effective sound control to minimize outside noises and between rooms (if the interior walls are insulated). Many people only focus on the energy savings that can be achieved with blow in cellulose insulation but overlook the benefits that come from improved sound insulation. If you have ever walked into a house that is not insulated you will immediately notice that noises from outside of the house are “louder” than in an insulated home.
Fire Resistance
Besides saving you money, cellulose insulation also provides extremely effective fire protection capabilities. Tests conducted by Underwriters Laboratories Inc.® show that Cellulose insulation provides an effective 1 hour fire rating. This will slow the spread of a fire allowing you more time to escape any danger. This is because cellulose is specially treated using Borate Compound Chemicals as a fire retardant in the manufacturing process to meet or exceed all fire safety requirements.
Energy Efficiency
Cellulose insulation improves the energy efficiency of your home by reducing heat transfer, keeping your space cooler in the summer and warmer in the winter. With its high R-value, cellulose insulation helps to minimize energy consumption and lower utility bills.

Frequently Asked Question
Does mold grow on cellulose insulation?
Yes, mold grows on cellulose insulation when it becomes very wet, and the good news is that it is treated to resist mold and usually stays in great condition in a dry, well sealed space.
The best prevention is strong air sealing and a proper, dense installation that helps limit condensation, along with fixing any roof or plumbing leaks quickly to keep the insulation performing at its best.

Does old cellulose insulation have asbestos?
No, cellulose insulation generally does not contain asbestos, as it is produced from recycled paper fibers instead of minerals. It became a popular, safer insulation option starting in the 1970s, and in older homes it can sometimes sit near other materials like vermiculite, so a quick professional check can offer extra peace of mind if you are unsure what is in the attic.
Is cellulose insulation a good fit for Chicago’s cold winters and humid summers?
Yes, cellulose insulation is an excellent fit for Chicago’s cold winters and humid summers because its dense coverage helps reduce air leakage and supports steady comfort through big temperature swings.
It also holds its insulating value well in extreme cold and can help manage seasonal moisture when the attic is properly ventilated. For the best results, target an attic level around R-49 to R-60 and use professional dense-pack installation where needed to get consistent coverage and strong, long-lasting performance.

If my roof develops a minor leak during a spring thaw, will cellulose insulation trap the water and cause my plaster to collapse?
Cellulose insulation can absorb and hold water during a minor spring-thaw leak, so addressing the leak quickly helps the insulation stay effective and keeps conditions dry.
A small, short-term leak usually will not cause plaster collapse, and quick repairs plus a simple check for any damp or clumped spots can keep the area light, dry, and on track before heavier wet patches have a chance to form.
With fast action and basic cleanup, you can protect your ceiling and maintain strong attic performance.

Will the R-value I pay for today still be there in five years, or will the Chicago wind-wash cause the cellulose to shift and settle?
Yes, in most cases, the R-value you pay for today will still be there in five years, especially when cellulose is installed to the correct settled depth in a Chicagoland attic.
Some minor settling early on is normal, and pros account for it by installing enough material so it settles right where it should. Because cellulose is denser than fiberglass and resists airflow better, pairing it with proper baffles at the eaves helps prevent wind-wash and keeps coverage consistent long-term.

Can cellulose help with ice dam issues common in Chicago winters, or do I need ventilation changes too?
Yes, cellulose can be a big help with ice dam issues in Chicago winters because its dense coverage reduces heat loss into the attic and helps keep the roof colder.
For the best results, pair it with attic air sealing and well-balanced ventilation, since steady soffit and ridge airflow helps the roof deck stay consistently cold and supports strong, reliable performance. When adding cellulose, baffles at the eaves are a smart upgrade to keep vents clear and performance strong.

Will cellulose create dust during installation, and how do installers keep the home clean?
Yes, cellulose can create some fine dust during installation, and the good news is that experienced crews have effective ways to keep the home clean and comfortable.
Installers typically deliver a clean process by isolating the work area with plastic sheeting, using wet-spray dust suppression to reduce airborne particles, and performing a thorough post-job cleanup around every access point. Once the cellulose is installed and settled, it stays in place and no longer produces dust.

Is cellulose treated for fire resistance, and how does it compare to other materials for fire safety?
Yes, cellulose insulation is typically treated with borate fire retardants, which helps it resist ignition and usually earn a Class 1 fire rating. In a fire, cellulose can form a helpful char barrier that improves fire resistance, whereas fiberglass can lose its form under very high heat. Overall, cellulose is widely considered a strong choice for fire safety, especially when installed correctly as part of a code-compliant assembly.
Are there Chicago or Illinois rebates or utility incentives for installing cellulose insulation?
Yes, homeowners in Chicagoland and Illinois can access rebates or utility incentives for installing cellulose insulation, including programs run by Nicor Gas (up to $700) and Peoples Gas (up to $ 1,850).
Homeowners can also take advantage of the Federal Tax Credit (25C), which offers 30% off the total cost of installation and air sealing materials, up to a maximum of $1,200 per year.
