Cellulose Insulation - What You Need to Know

What is Loose Fill Cellulose Insulation?

Loose-fill cellulose insulation also known as blown-in insulation and is one of the most common attic insulation types. Blown-in insulation mainly refers to cellulose material that is blown into the attic to fill up empty spaces and wall cavities to achieve thermal insulation. This is a cost-effective insulation method that covers cavities in attic floors and slows down the transmission of heat and cold in your house. Cellulose insulation can be derived from plant sources but for commercial insulation purposes, it is used in the form of wood or paper-based products such as recycled newspapers, cardboard, or other consumer waste paper products.

How is Cellulose Insulation Applied in Homes & Commercial Properties?

Cellulose insulation installation is a fairly simple procedure and requires only a small team of installers to get the job done. The cellulose material is mostly made from recycled newspapers and is treated with boric acid to make it fire-resistant. The cellulose is stored in a mechanical blower that churns and mixes it with air to loosen it up. This fluffed-up and dense cellulose material is used to fill up cavities and empty spaces in the structure of the house with the help of flexible tubes. The cellulose can be applied on top of fiberglass insulation in the form of a thick blanket or in the case of no insulation, holes can be drilled into finished walls to blow in the cellulose.

What Are the Benefits of Applying Cellulose Insulation?

The main benefit of applying cellulose insulation comes into play when the objective is to insulate already finished spaces enclosed with walls. Instead of having to knock down the wall, cavities can be drilled and cellulose can be blown in to insulate such spaces. · Cellulose insulation is more cost-effective and has an R-value of 3.5 per inch of thickness as compared to fiberglass insulation which has an R-value of 2.2-2.7 per inch of thickness. · If you are concerned about reducing your carbon footprint, cellulose insulation is an eco-friendly insulation option as it is made from recycled paper products that do not emit harmful toxins. · Treatment of boric acid with cellulose makes it fire-resistant and mold-resistant so you do not have to worry about mold growth and pest infestation with cellulose insulation.

Blown-In Cellulose Insulation vs Other Types of Insulation?

If you are looking for an environmentally friendly insulation option for your home, cellulose insulation is the best option. Not only does it reduce your carbon footprint, but it also provides better thermal resistance as compared to fiberglass insulation due to its higher R-value. Fiberglass batts are more difficult to install and may have breaks in the thermal barrier because it needs to be cut exactly to fit the space. If not installed properly, your property will be poorly insulated. Blown-in cellulose insulation is easier to install because the insulation material can be filled into every nook and cranny with the help of a mechanical blower.


Cellulose insulation is by far the most environmentally friendly insulation option available in the market that is also cost-effective. It is made from waste paper products that would otherwise emit harmful gasses when disposed of in landfills. When treated with boric acid, it becomes safe for installation in homes and minimizes the release of harmful toxins.

Cellulose insulation is made up of about 80-85% recycled newspapers which are passed through borate treatment to make them fire-resistant. However, despite the high fire safety rating, it is not a fire-proof insulation option.

One of the most common mistakes that can occur as a result of poor cellulose insulation is only filling the walls up partially with cellulose. This can happen when the holes are not drilled strategically or drilled too low in the walls and the insulation does not reach all the nooks and corners of the attic.

Another common mistake that insulation installers make is not filling insulation in air leaks around ducts, wires, and pipes. No gaps should be left while applying cellulose insulation otherwise there will be breaks in the thermal barrier.

Blown-in insulation lasts for about 20-30 years depending on the insulation material that is used. Fiberglass insulation may last for a longer time because it is made of plastic which does not degrade easily. Cellulose insulation is composed of recycled natural materials such as paper so it can last for up to 2-3 decades.

Due to its higher thermal resistance, blown-in cellulose insulation is the best insulation option for homes. Not only does it help you remain energy efficient but it is also the most green-friendly and budget-friendly solution when it comes to blown-in insulation.

Cellulose insulation prevents the growth of mold by creating a tight air barrier that cuts off the main moisture source that mold needs to thrive on.  Borate treatment is also applied to cellulose making the insulation resistant to mold growth.

Rodents cannot nest in cellulose insulation because there is no space for them to burrow and make a nest. If they try to nest in cellulose insulation, it collapses on them. Therefore, you will not have to worry about pests infestation with cellulose insulation.
