What types of cavities can cellulose loose fill insulation be blown into?

Cellulose loose fill insulation is particularly well-suited for use in wall cavities due to its composition and application method. It is made from recycled paper products and can easily adapt to the shape and size of various wall spaces, allowing for effective coverage and thermal resistance. When blown into wall cavities, cellulose insulation can densely pack into the available space, thereby minimizing thermal bridging and air infiltration, which enhances the overall energy efficiency of the building.

While it is possible to use cellulose insulation in other areas, such as under floors or in attics, the primary advantage of using cellulose in wall cavities lies in its ability to navigate and fill those irregular spaces more efficiently than many other insulating materials. Wall cavities typically require insulation that not only fits well but also has the capability to reduce noise and provide moisture control, functions that cellulose insulation excels at due to its air-retentive properties.

Cellulose is not used in appliances or on roofs in a conventional sense, as these areas typically require different insulating strategies and materials designed for unique structural and performance demands.
