Blow-in insulation, also known as loose-fill insulation, is made of small particles of fiber—typically fiberglass, cellulose, or mineral wool—that are blown into attics, walls, or hard-to-reach spaces using a specialized machine.

This method is ideal for adding insulation to existing structures without major renovations. It fills in around obstructions and tight spaces, creating a consistent thermal barrier that helps reduce energy costs and improve indoor comfort.

Blow-in insulation is commonly used in:

• Attics

• Wall cavities

• Crawl spaces

• Retrofit or upgrade projects

It’s a fast, effective solution for increasing R-values and improving energy efficiency in both residential and commercial buildings.
