What Is Blown Insulation? A Quick Guide
While your attic is often the hiding place of out-of-season holiday decor and forgotten clothes, it’s also the place where you can spend a little to save a lot.
Think of it this way: no matter the insulation cost, a well-insulated attic can shave 10% to 50% off your heating bill.
If your attic is due for a refresh, here’s a look at blown insulation and why it might be the right fit for your home.
What is Blown Insulation?
Blown insulation is the process of filling joist and stud cavities and covering attic floors with a blow-in cellulose. This material is typically made from cellulose, fiberglass, and other materials. Regardless of the components, the final result is thick, lumpy, and has the consistency of down feathers.
There are three common types:
- Loose-fill fiberglass
- Rock wool
Each has a slightly different insulation value. Sincre recommended values vary by region, this map is a good way to check the recommended value in your area.
The Blown Attic Insulation Process
The “blown” aspect refers to the process by which the insulation is installed.
Installation requires the use of a specialized insulatio machine to “blow” insulation into desired parts of your attic. When the machine turns on, it churns out insulation material with paddles to loosen it and mix it with the air. The insulation is then blown through a hose at the desired spot.
While many home improvement stores rent such machines, it’s best to hire a professional. There is still some prep work involved with blown insulation, and you want to make sure it’s done correctly.
Blown Insulation Benefits
One of the biggest benefits of blown insulation is that it spares homeowners the hassle attached to batt insulation.
Batt insulation consists of thick strips of fiberglass materials. These strips are cut to fit in between studs and joists before the wallboard goes up. On one hand, this greatly increases your insulation value. On the other hand, if you have a preexisting home, you would have to rip out the drywall, tear out the old insulation, cut the strips custom, and replace the strips and the drywall.
In other words, it’s a costly, time-consuming hassle.
Blown insulation is designed to fit easily in small spaces and seal small gaps as it settles, preventing pesky cold air from sneaking through (or warm air from slipping out). Plus, since the process quite literally involves blowing material onto the space, it’s relatively straightforward for a technician once they have the machine ready and prepwork finished.
