The Process of Insulating Existing Walls

At Anderson Insulation we work on insulating new construction homes but also houses that are older or for one reason or another have a problem with their insulation. For these homes that are already established, you don’t need to tear existing walls apart in order to install new insulation. In fact, most people don’t want to cause all this added construction, so through small holes from either inside or outside we are able to insulate existing spaces.

With a small hole in between a half to two inches, insulation can be injected directly into a wall. Here are the two types of insulation you can use with existing walls.

1. Cellulose:

Made out of recycled newsprint and wood fiber, Cellulose can be blown into walls until it is densely packed.

2. Spray Foam:

Spray foam is a liquid that when applied very slowly expands in size. The slow rise allows for spray foam to be injected into the smallest of holes in your wall.

Fun Facts About Spray Foam & Cellulose Insulation:

• If you are environmentally conscious, cellulose might be the option for you, as it’s made up of 85% recycled products.
• While cellulose gets used in the walls for existing walls, it can often be found in the attic for new construction products today
• Spray Foam can reduce and reach irregular or hard to reach areas
