How Long Does Blown In Insulation Take To Install? - An Expert's Perspective

Installing blown in insulation is a relatively speedy process that can be completed in a single day in most cases. However, the duration of the installation depends on the type of insulation being used, the size of the area being insulated, and whether or not existing insulation needs to be removed. Blow insulation, also known as loose fill insulation, is a method of filling the cavities of walls or covering attic floors with any loose material that has a good insulating R-value. The most common material used for blowing applications is cellulose material.

It is much faster than traditional insulation methods such as head-to-head batting and balancing, and can be used to improve the R-value of home insulation. If you are installing blown cellulose insulation in a 1,000-square-foot attic, the project will likely only take a few hours. However, if you are installing insulation throughout your entire home, it can take much longer. If your old insulation needs to be removed due to pest excrement or toxic insulation, the installation process may take a couple of days to complete.

When installing blown in insulation, a small team will come to your house and one member of the team will use a hose to spray spongy insulating material through the floor and cavities, while another one introduces fiberglass mineral wool into a unit under the attic or outside the house. It is important to note that if insulation is installed too close to recessed lights (also known as tin lights or tall hats), heat can't be dissipated and light bulbs can burn out more easily. In addition, you may have to stay outside your home for 24 hours after installation to let certain types of insulation dry safely due to the fumes they can emit. Both blow insulation and spray insulation can involve a lot of loud machinery.

Overall, blown in insulation is an excellent solution for making your home more heat resistant and energy efficient. It is quite comparable in cost and R value compared to fiberglass slats or blankets, and offers a much faster way to significantly improve attic insulation. If you need to install new insulation in your home, you can expect it to take anywhere from a few hours to a couple of days depending on the size of the area being insulated and whether or not existing insulation needs to be removed.
