A Guide to Blown-In Insulation

Details

Contractors working with blown-in insulation spray mineral fibers or similar insulating materials into wall cavities, flooring, and attics. This provides crucial protection against heat loss, which offers several benefits for your home, budget, and the environment. Below, learn more about the different types of blown-in insulation and their benefits.

Types

Also called loose-fill insulation, this product is available in three different varieties. Loose-fill fiberglass is made from glass that has been heated to a liquid and spun into strands. It provides a high level of resistance to moisture, fire, and heat.

Cellulose is comprised of shredded cardboard or newspaper and is the most common type of blown-in insulation used in American homes. It has been chemically treated to enhance its fire- and mold-resistant capabilities. 

Rock wool, or mineral wool, comes from the slag of blast furnaces, which is a natural byproduct of firing iron. The heated slag is mixed with additional minerals and spun into a woollike material that boasts superior fire resistance.

Benefits

Blown-in materials minimize heat transfer, keeping your home warmer in winter and cooler in summer. This makes your home safer and more comfortable and reduces heating and cooling system usage. Your energy bills will be lower, and your home's carbon footprint will be lighter.

The application of blown-in insulation is fast, with minimal disruptions to your property or household. As its name implies, it is blown directly into the desired cavities. You do not need to remove or replace any drywall. The insulation contractor makes two holes near the top and bottom of the wall, then uses a blower to fill the space with insulation from the top down. The holes are filled and painted to match the walls. The application process is easy and smooth, labor costs are minimal, and you can have your entire installation completed in just a few hours.
