Blown-in insulation is a method of filling wall cavities, attics, or floors with loose insulation material using a blowing machine. It commonly uses cellulose, fiberglass, or mineral wool to reduce heat transfer and improve energy efficiency.
Blown-in insulation is applied using a hose that distributes loose-fill material into open spaces. It fills gaps and crevices, helping to create a more consistent thermal barrier across the insulated area.
The most common materials include cellulose (made from recycled paper treated for fire resistance), fiberglass (spun glass fibers), and mineral wool (natural or synthetic rock fibers). Each has distinct properties in terms of thermal performance and moisture resistance.
Yes, it is often used in retrofit projects because it can be installed through small holes in walls or ceilings, reducing the need for major construction or drywall removal.
Installation usually takes a few hours to a full day, depending on the size of the space and ease of access. Attics typically require less time than wall cavity installations.
Costs vary based on the type of material used, the size of the area, and accessibility. On average, expect to pay between $1.00 and $2.50 per square foot, including labor and materials.
The R-value depends on the material. Cellulose offers around R-3.2 to R-3.8 per inch, fiberglass ranges from R-2.2 to R-2.7 per inch, and mineral wool is about R-3.0 to R-3.3 per inch.
Blown-in insulation is loose and conforms to irregular spaces, making it ideal for retrofits or attics. Batt insulation comes in pre-cut panels and is generally better suited for open walls during new construction.
Yes, by reducing air leaks and improving thermal resistance, blown-in insulation can significantly lower heating and cooling costs over time.
Some settling may occur, particularly with cellulose. However, proper installation techniques can limit settling and maintain consistent thermal performance.
Cellulose is treated with fire retardants to reduce flammability. Fiberglass and mineral wool are naturally non-combustible. Always check that materials meet local fire safety codes.
Yes, blown-in insulation helps reduce noise transmission by filling gaps in walls, floors, and ceilings. Cellulose typically offers better soundproofing than fiberglass.
Fiberglass may cause irritation if inhaled during installation, but once sealed, it poses minimal risk. Cellulose is usually treated to minimize mold and dust concerns, but sensitive individuals should consult their installer.
Homeowners should clear access to the work areas, especially attics or crawl spaces. The insulation contractor will assess air sealing needs before installation begins.
Yes, additional layers can be added to improve R-value, provided the existing insulation is dry and free from mold or pests.
Periodic checks are recommended to ensure the insulation hasn’t shifted or been affected by moisture. It's especially important after roof leaks or pest infestations.
High energy bills, uneven temperatures, cold drafts, or ice dams on the roof may indicate insufficient insulation.
