Cellulose Insulation: Different Types of Cellulose

Do you have a home that is not living up to your standards? Is your air conditioning bill skyrocketing every month? You might want to consider cellulose insulation. Cellulose insulation is environmentally friendly, and it can be blown into various parts of the home. It can be blown into the attic, between the span and rafters, and inside the wall cavities. These serve to make your home energy-efficient and more comfortable.

Types of Cellulose Insulation

There are several types of cellulose products for insulating your home. The one thing they all share in common is that they are very adaptable and can suit your home’s needs just fine. The three standard cellulose insulation products are as below:

Loose-Fill or Blown Cellulose

This type of cellulose insulation is blown into walls and attics. It can be installed in any space with an access opening, so it’s perfect for places like crawl spaces where you don’t have much room to work with.

Blown-in cellulose insulation will usually come compressed and wrapped tightly on a roll or as loose-fill, which is just a bag of loose cellulose insulation.

Densely-Packed Cellulose

This type is most often used in places where you have a lot of space and want to fill it with insulation. Densely-packed cellulose can also provide the best sound dampening, so if that’s an issue, this might be your product.

Densely packed cellulose will typically come on sheets that are easy to cut and install.

Densely-packed cellulose is the most expensive type of insulation, but it lasts for decades and saves energy bills over time. 

The only downside with dense-pack cellulose is that it will increase the size of your home.

Wet Spray Cellulose

This type of cellulose is sprayed as a liquid, and then it dries. Wet spray cellulose also has the best sound dampening quality but not as good as the dense pack variety.

Wet-spray cellulose can be installed between rafters in your home or blown into wall cavities with an insulation gun to fill all the nooks and crannies.

This is the most cost-effective type of cellulose insulation, but it does not last as long as other types. Wet-spray cellulose will need to be replaced every five years or so, making it expensive in the long run.

The energy savings are low because wet spray cellulose is installed as a liquid. 

Wet spray cellulose is not an environmentalist recommended option because it contains formaldehyde which can release greenhouse gases.

This type of insulation needs to be sprayed on the surface and then dried before installation, so there are some safety concerns. Wet-spray cellulose also has a shorter lifespan.

The most environmentally friendly type of cellulose insulation is blown in because it does not contain formaldehyde and has a longer life span than wet spray cellulose insulation. It also needs to be installed as loose-fill, so there are no safety concerns with this type of installation.

Blown-in cellulose does need to be installed by a professional.

Blown-in cellulose insulation also reduces the thermal bridging and air infiltration that would otherwise occur with other types of installation. It has been proven to be efficient and effective for insulating against cold weather climates, so it is an environmentally friendly option.
