 What is Blown-In Insulation?

A blown-in insulation contractor in an attic.

Blown in Insulation provides an expert choice for energy-saving options for your attics or walls in your home. Also known as loose-fill, this insulation is made up of loose particles of fiberglass or cellulose, that are easily blown around in your attic or wall insulating any possible crack or crevice along the way. Once it sets, this type of fiberglass insulation fills those air gaps will no longer let out heat during the winter or the cool air during the summer. 

Blown in insulation is comprised of either fiberglass insulation or cellulose insulation. The fiberglass version is made of plastic reinforced from very small glass fibers. It’s commonly found in most homes — especially one of the main attic insulation sources — and helps provide assistance with soundproofing. Cellulose insulation is made from recycled paper content such as shredded recycled paper and cardboard boxes. Cellulose can provide your home or business with sustainability and easily fits in the gaps of your current insulation to keep hot or cool air intact.

Frequent Questions About Insulation


Does Blown In Insulation Need to be Replaced?

When you insulate your home, there are a few possibilities to choose from. Blown-In insulation has the ability to last 80 to 100 years as long as it stays undamaged. This is why it’s perfect for attic insulation. It’s always a good idea to have your insulation inspected when you have any repairs or damages you’re getting fixed.


Should I remove old insulation before blowing in the new?

It depends. If your contractor sees mildew or damage from rodents in your home, it’s best to remove the old. If it still looks in good shape and there are just low levels we can easily add the new insulation.


How do you know if you need more insulation in your attic?

Take a look in your attic. If you aren’t able to see the floor joints then you should be set. Adding any more attic insulation won’t make the energy-saving difference you’re looking for. For the best control, it’s always important to check your insulation levels.


How long does it take for blown in insulation to settle?

On average, most of the settling will occur within the first couple of months of having the service done in your home. But over the next two years, the insulation will continue settling.
