Top Differences to Consider When Choosing Between Blown-In Cellulose & Fiberglass Insulation
Insulation is an essential part of any home. It helps keep your living space comfortable, reduces energy bills, and contributes to environmental sustainability. If you are about to move into a new home that needs insulation, or you are looking to upgrade the old insulation in your current home, you may be wondering which type of insulation is best for your budget, space, and lifestyle. The two most common options are blown-in cellulose and fiberglass insulation. Each comes with its own set of benefits and downsides, which might make one of them a better option for you than the other. In this blog, we will discuss the main differences between the two, including their price, durability, installation process, maintenance requirements, and more.
What is Blown-In Cellulose Insulation?
Blown-in cellulose is a type of insulation made from shredded recycled paper and cardboard that has been treated to be fire-resistant. Unlike traditional forms of insulation, blown-in cellulose is installed by blowing the material into your walls or attic using specialized equipment. This method allows for a more precise and thorough application, especially in hard-to-reach areas.
What is Fiberglass Insulation?
As its name suggests, Fiberglass insulation is made from fine glass fibers that are spun into wool-like material. This form of insulation can be the easiest to spot with its pink, yellow, or white cotton candy-like texture. Fiberglass insulation heats your home using air pockets that trap heat, making it a great insulator for attics, basements, and other rooms that do not receive a lot of foot traffic.
How to Know When It's Time to Install New Insulation
As a homeowner, keeping the insulation up-to-date is essential for your home’s efficiency. If you struggle to keep your home warm in the winter and cool in the summer, this may be a sign that it is time to upgrade your insulation. Other signs include:
- Suddenly high utility bills,
- Drafty or condensated windows,
- And visible damage to your insulation.
If you notice any of these signs, it’s time to contact Absolute Home Insulation Plus for installations and replacements.
Key Differences Between Blown-In Cellulose & Fiberglass Insulation
Blown-In Cellulose is More Affordable in Short & Long Term
The cost and affordability of insulation is one of the main factors homeowners tend to consider. If you are looking for cheaper installation and lifetime maintenance, blown-in cellulose is comparatively less expensive than fiberglass insulation. Due to its makeup and installation process, blown-in cellulose usually costs 20-30% less than fiberglass insulation.
Fiberglass Insulation is More Durable & Longer-Lasting
When comparing the durability and lifespan of the two, fiberglass tends to hold up better over time. Since blown-in cellulose is made from paper and cardboard, it can be prone to moisture damage and settling, which can reduce its effectiveness over time. On average, fiberglass insulation can last up to 50 years, while blown-in cellulose may need to be replaced in 20-30 years.
Blown-In Cellulose Has Better Soundproofing
One of the added benefits of blown-in cellulose insulation is its soundproofing capabilities. The dense material can help reduce outside noise and create a more peaceful home environment. This can be especially beneficial for homes in busy neighborhoods or near highways.
Fiberglass Insulation is Easier to Install & Requires Less Maintenance
While blown-in cellulose costs less over time, fiberglass insulation is generally easier to install. Also, due to its durability, fiberglass insulation requires less maintenance compared to blown-in cellulose. Once installed, it can last for decades without needing to be replaced or refilled.
Blown-In Cellulose is More Environmentally Friendly
With environmental impact being a growing concern for many homeowners, the materials used to make insulation and the debris they emit during installation are important to consider. Blown-in cellulose is made from recycled materials, making it more eco-friendly than fiberglass insulation. Additionally, the blown-in installation process produces less waste and does not require any chemicals or harmful substances.
Fiberglass Insulation Offers Better Fire Resistance
Fires are one of the leading causes of property damage, and having fire-resistant insulation can help reduce the risk for your home. Fiberglass insulation is naturally non-flammable and will not cause a fire to spread further beyond its source. Since blown-in cellulose is made of paper materials, it requires a fire-resistant treatment that may not be as effective in preventing fire damage.
