Batt vs. Blown-In Insulation

If you need to re-insulate your house, you’ve probably been doing your research. As you perhaps can tell, there are many different materials (fiberglass, cellulose, etc.) and methods of installation (blown-in, spray, etc.). Sometimes materials are even installed multiple ways.

Take one of the most commonly installed types of insulation for example—fiberglass. It is available as both batt and blown-in insulation. What is the difference between the two?

Blown-In Insulation vs. Batts

How is batt insulation different than blown-in insulation?

Typically made of fiberglass, batt insulation is available in pre-cut panels and is one of the most common forms of insulation. It’s often installed in spaces relatively free of obstructions (such as pipes and wiring). Batt insulation is smoother looking and can be almost be thought of as a thermal blanket.

Blown-in insulation, also referred to as loose-fill insulation, is installed using a blowing machine. Depending on the material of the insulation, the installation method may vary slightly.

Both blown-in and batt insulation can be installed in different areas of a home, including the attic and the walls. A professional will be able to assess your home and insulation needs to determine which type of insulation would be an ideal solution.
