Cellulose Blown-in Insulation

Cellulose Blown-in Insulation is an insulation type in which we blow cellulose material. Plants are the main source of raw cellulose.

Cellulose Blown-in Insulation is an insulation type in which we blow cellulose material. Plants are the main source of raw cellulose.

Generally, Insulation is required to maintain our surrounding temperature.

In the absence of insulation, you feel freezing temperatures in winter and feel melting temperatures in summer. This is just simple physics. Air travels from the outer environment into the house because it is traveling from a higher concentration place to a lower concentration area. Like cellulose blown-in insulation, all the insulation options act as a barrier to block outer harsh air. In addition, cellulose blown-in insulation has further advantages. We will discuss them later.

What are the requirements for cellulose blown-in insulation?


  • Cellulose

Other materials

  • Blow machine
  • Hopper
  • Personal protective equipment
  • Spray foam

What is the difference between cellulose blown-in insulation and other types of insulation?

Cellulose blown-in insulations

We use cellulose blown-in insulation in closed building walls. This is easier than other types. This is applied in attics due to its nature which reaches every place.

Other types of insulations

We use many of them in open building walls.

How to install it?

Make a strong barrier

The first step is to fill up all the gaps by using spray foam. Always make sure to check this carefully.

Identify the level of Insulation in the attic and make holes in the walls

Furthermore, it is necessary to measure the level of insulation which we want to install in this step. We face visual problems due to the dust during the installation,

Preparation of the insulation and the blower is a must

Additionally, before installing the cellulose, it is important to put it in a hopper for its preparation. Cellulose should be chopped very well for good results. And set the blowing machine outside your house.

Blow the cellulose insulation

In this step, finally, you are blowing the cellulose in the walls or other places where you want to. But after wearing personal saving equipment to protect yourself from the dust. Dust may be the cause of respiratory disease.

What are the common mistakes in the installation?

If I am not mistaken, sometimes we are not able to close the gaps. Similarly, in many cases, we miss the gaps with amazing material. And don’t take fast and uneven steps while installing insulation. Take slow steps and do amazing work carefully.

What are the pros and cons of cellulose blown-in insulation?


As far as I know, Cellulose blown-in insulation is a type that is very easy to install. Moreover, it stops heat by having a greater R-value. If you want to save your environment, then this is an excellent option for you. In addition, this type is very good at accepting any kind of shape.


On the contrary, the shape-changing property of cellulose is not good after a certain period of time. Besides, it is a fungal lover. When mold gets into the material, its R-values reduce heat-controlling property lessens

I hope the above information will help you to understand the cellulose blown-in insulation. For further details, your helper Ray General Contractor is available via email or a call.

Batt insulation is easily available and used in all places. Whereas, batt insulation is not for a longer period of time.
