Blown-In Insulation

blown in cellulose insulation in attic

No two Milwaukee area homes are the same, and at Wisconsin Home Improvement, we help local homeowners save money and improve their home comfort by choosing the right insulation type to upgrade their houses with. One of the best kinds of insulation we use in our home retrofit work is blown-in insulation—learn more about how blown insulation can benefit your home.

What Is Blown In Insulation Made Of?

There are two main insulation materials used for blown in insulation installation: fiberglass and cellulose.

Blown In Fiberglass

Fiberglass is often made from recycled glass and plastic. If you think of “the pink stuff” when you think of insulation, you’re thinking of fiberglass batts, where the fiberglass is attached to paper sheets and cut into rolls. Blown in fiberglass is not packed into rolls, but otherwise the same. 

Blown in Cellulose

Cellulose is made mostly from recycled newspaper that’s been treated with flame retardant chemicals. Cellulose is usually installed in one of two ways—loose fill and dense-packed (keep reading to learn the difference between the two).

How is Blown In Insulation Installed?

When you think about replacing the insulation in your walls or other hard to reach areas of your home, you might worry that an insulation contractor will need to tear down your old walls and create a huge mess. But actually, blown in insulation is easy to install, with minimal clean-up. Small holes are strategically drilled into the walls or areas to be insulated, and insulation is—you guessed it—blown in to the holes, creating a densely-packed and compressed layer of insulation in areas like wall cavities. Another method of blowing in insulation is to simply blow a loose fill layer of insulation over the floor of an attic, where space and the height of the insulation layer isn’t as much of an issue.

Because cellulose and fiberglass is loose when it’s blown in, it can fit itself snugly into crevices and areas where fiberglass batts can’t, which means your home will be more energy efficient and cost effective to heat and cool.

Where Can Blown In Insulation Be Used in a Home?

You want to keep fiberglass and cellulose insulation away from potentially damp or wet parts of your home, as moisture can significantly reduce the effectiveness of their insulating qualities. But blown in insulation is great for most other places in your home that might need an insulation upgrade, including:

The Importance of Air Sealing When You Install Blown In Insulation

Like moisture, blown insulation materials like fiberglass and cellulose perform worse when exposed to air movement. That’s why it’s crucial to seal up the tiny cracks and gaps in your home before you install new insulation. Insulation and air sealing work together—you’ll see the maximum benefit when you do both at the same time.

    I really feel compelled to give a "shout out" to everyone I have come into contact with at WHI. First off - Jody. You are so friendly and helpful on the phone, forgiving me for my inability to "on-line sign", switching up of dates, declining work and then changing my mind.

  • Tim S.

    Steve, just a side note and I would not send this if it was not completely true - Mike and Pete were both fantastic. I was impressed. We had just had other major construction and have many comparatives for the work WHI did. I would come home and never know they had even been there.
