The Advantages And Disadvantages Of Cellulose Insulation


Heating and cooling have become a household priority, with homeowners continually searching for cost-effective ways to regulate temperature. Insulation is a useful way to maintain comfortable indoor temperatures, and cellulose insulation is one of the options available. It is made from recycled materials, usually paper, and can be blown into attics, walls, and other crawl spaces.

While cellulose insulation has its benefits, it may also not be suitable for all homeowners. This article will explore the advantages and disadvantages of cellulose insulation and help homeowners make an informed decision when considering insulation options for their homes.

Advantages of Cellulose Insulation

Here are some of the advantages of using cellulose insulation:

Environmentally Friendly

Cellulose insulation is made from recycled materials, most commonly from recycled newspaper. It is an environmentally friendly insulation option, making it an attractive choice for people who care about the environment.


Cellulose insulation is an affordable insulation option compared to other insulation materials. Additionally, it has a relatively low installation cost, making it a cost-effective insulation option.

Good Thermal Performance

Cellulose insulation has good thermal performance and can provide effective insulation. When installed correctly, it can insulate the area efficiently and reduce heat loss, thus lowering heating costs.

Good Soundproofing Properties

Cellulose insulation has good soundproofing properties. It can reduce sound transmission, providing a quieter environment, making it an excellent choice for people living in noisy areas.

Good Fire Resistance

Cellulose insulation can provide good fire resistance. It is coated with fire-retardant chemicals that make it resistant to fire, making it a safe insulation option.

Disadvantages of Cellulose Insulation

While cellulose insulation has its benefits, it may also have some disadvantages. Here are some of the disadvantages of using cellulose insulation:

Susceptible to Moisture Damage

Cellulose insulation is a paper-based product, making it susceptible to moisture damage. Water exposure can affect its thermal performance, decrease its ability to insulate efficiently, and ultimately cause mold growth.

Prone to Settling

Cellulose insulation has been known to settle over time, causing it to lose its insulating value. When the insulation settles, air pockets are formed, which can reduce thermal performance and increase energy consumption.

Difficult to Remove and Reinstall

Cellulose insulation is difficult to remove and reinstall. If homeowners need to access the walls and roofs exposed to cellulose insulation, they may need to hire professionals, which can be costly.

Dusty and Can Cause Respiratory Issues

Cellulose insulation is dusty, and when disturbed, it can cause respiratory issues such as coughing, wheezing, and asthma attacks. This makes it challenging for homeowners to install it themselves, and it requires special equipment and protective gear to install safely.


Choosing the right insulation option for your home can be challenging, but weighing the pros and cons of each option can help determine which one is best for you. Cellulose insulation has many benefits, such as being environmentally friendly, cost-effective, and providing good soundproofing and fire resistance properties. However, it is prone to moisture damage, settling over time, difficult to remove and reinstall, and can cause respiratory issues when disturbed. Knowing these advantages and disadvantages can make it easier for homeowners to determine if cellulose insulation is suitable for their homes, and help them make an informed decision.
