Blown-In Cellulose Insulation
Blown-In Cellulose Insulation : Eco-Friendly Attic Protection
Blown-in cellulose insulation is a high-density material made primarily from recycled newsprint and paper. These paper fibers are treated with natural borates to create a product that is both fire-resistant and unattractive to pests. This material is a top choice for homeowners who prioritize eco-friendly solutions and superior air sealing.
The tiny fibers allow the blown-in cellulose insulation to pack tightly into wall cavities and attic corners. This density creates a strong thermal barrier that outperforms many other loose-fill materials. It effectively slows down heat transfer, keeping your living spaces cool in the summer and warm in the winter.
My Insulation Guy installers use specialized machines to distribute the material evenly. This process ensures that every gap around wires and pipes is fully filled. Choosing blown-in cellulose insulation is a smart way to upgrade your home’s energy efficiency using sustainable, recycled resources.
Forms and Applications of Cellulose
This material is most commonly used as a loose-fill product for attics, but it also works for specialized wall applications.
- Attic Loose-Fill: Technicians blow a thick blanket of blown-in cellulose insulation over the attic floor. It easily covers existing insulation to increase the total R-value of the home.
- Wall Cavity Injection: For finished walls, we can inject the material through small access holes. This dense-pack method fills the entire wall stud space to stop drafts and reduce outside noise.
- New Construction: We install the material in open wall bays using a temporary mesh to hold the fibers in place until the drywall is installed.
Using blown-in cellulose insulation in these areas creates a seamless cap on your home. This prevents the chimney effect, where warm air escapes through the roof, leading to lower monthly utility costs.
Key Benefits of Cellulose
The physical properties of this material provide unique advantages for a house. Blown-in cellulose insulation is more than just a thermal barrier, it improves the overall health and safety of the building.
- Superior Soundproofing: The high density of the paper fibers blocks sound better than lighter materials. It significantly reduces noise from airplanes, traffic, and loud neighbors.
- Fire Retardant: The borate treatment allows blown-in cellulose insulation to withstand high heat. It can help slow the spread of flames through a wall or ceiling.
- Pest Deterrent: The same minerals that protect against fire also turn away insects and rodents. Pests generally avoid nesting in treated cellulose fibers.
- Eco-Friendly Choice: Since it consists of up to 80% recycled paper, this is one of the greenest insulation options available. It requires very little energy to manufacture compared to foam or glass-based products.
Our Installation Process
My Insulation Guy follows a strict protocol to ensure the blown-in cellulose insulation stays effective for decades. We focus on proper density to prevent the material from settling too much over time.
- Preparation and Sealing: We start by sealing air leaks in the attic floor with foam. This makes sure the blown-in cellulose insulation sits on a solid, airtight base.
- Baffle Installation: Our crew places rafter vents to keep your attic ventilation clear. This prevents the material from blocking the airflow needed to keep your roof cool.
- Calibrated Blowing: We adjust our machines to the correct air-to-material ratio. This creates a dense pack that provides the maximum R-value per inch.
- Depth Verification: We use permanent markers to show that the blown-in cellulose insulation has reached the target thickness across the entire space.

Frequently Asked Questions
Is blown-in cellulose insulation safe for people with allergies?
The material is generally considered hypoallergenic and does not contain the harsh chemicals or formaldehyde found in some older products. It is treated with natural minerals that do not release harmful fumes into the home. Professional installation keeps the dust contained in the attic or wall space.
How long does this material last?
Can you install it over old fiberglass?
Yes, adding blown-in cellulose insulation over old fiberglass batts is an excellent way to improve performance. The heavy cellulose fibers fill the gaps that the old fiberglass missed, creating a much better air seal for the house.
Will the weight of blown-in cellulose damage my ceiling?
When installed by professionals, the weight of the material is not a threat to your drywall. We calculate the correct depth and density to stay within the load limits of standard ceiling joists. This makes sure you get a high R-value without putting stress on the structure of your home.
What happens if the material gets wet from a roof leak?
While blown-in cellulose insulation is treated to resist mold, it is an absorbent material. Minor dampness can often dry out if the attic has proper ventilation. However, if a major leak saturates the fibers, they can clump together and lose their effectiveness. In cases of heavy water damage, we recommend removing the wet sections and replacing them with fresh material.
