Blowing wool insulation, also known as blown-in wool insulation, is a type of insulation material that is installed by blowing or spraying loose fibers into an area. It is commonly used in attics, walls, and other hard-to-reach spaces.


The installation process for blowing wool insulation typically involves the following steps:

  1. Preparation: Before starting the installation, ensure that the area to be insulated is clean and free of debris. Any existing insulation or obstacles should be removed or properly addressed.

  2. Equipment Setup: Set up the blowing wool insulation equipment, which typically includes a blowing machine and a hose. The machine is used to break up the insulation material and blow it into the desired area. Connect the hose to the machine and position it in a convenient location for accessing the installation area.

  3. Material Loading: Load the blowing wool insulation material into the machine's hopper. The insulation material is typically made of natural fibers, such as wool or cellulose, which are treated to be fire-resistant and pest-resistant.

  4. Installation: Start the machine and feed the insulation material into the hose. Position the hose at the desired location and start blowing the insulation into the area. Move the hose around to ensure even coverage and fill any gaps or voids in the insulation.

  5. Leveling and Compression: After the insulation is blown into the area, it may be necessary to level and compress it to achieve the desired insulation thickness and density. This can be done using a rake or a similar tool to spread and compact the insulation material.

  6. Finishing: Once the blowing wool insulation is installed, any access points or openings used for installation should be properly sealed to prevent air leakage and ensure the insulation's effectiveness. This may include sealing holes or gaps with caulk or foam.


Blowing wool insulation offers several benefits, including excellent thermal performance, sound insulation, and fire resistance. It can be a cost-effective and efficient option for insulating hard-to-reach areas and irregularly shaped spaces. However, it is important to follow ours guidelines and consult with professionals for the proper installation of blowing wool insulation to ensure optimal results.
