Do you need a blower for loose insulation?

Do you need a blower for loose insulation?

Since cellulose insulation is compressively packaged you cannot install it without using a blowing machine. I do not recommend trying to do this by hand. “A few bags” may not qualify you for loan of a machine, but you can certainly rent one from a big box home center or an equiment rental service.

Which type of blown in insulation is best?

Fiberglass
Fiberglass, cotton, and mineral wool can all work as loose-fill insulation material, but the far and away top choice for blown-in insulation is fiberglass. Contrary to batts insulation, blown-in fiberglass insulation is perfect for filling in tight voids around wiring, pipes, or any area with awkward framing.

Can you put blown in insulation over batt insulation?

If the vapor retarder is correctly positioned, that is under the insulation directly against the ceiling, you can blow insulation over the batts. In fact, the batt and blow approach is a recommended and common technique for overcoming the endemic problems of batt installation.

Is blown-in insulation cheaper than rolls?

Blown-in insulation is typically more expensive than rolled insulation. However, this difference isn’t by that much. Blow-in insulation can cost between $1 to $1.50 per square foot. Rolled insulation, on the other hand, can be purchased for well under $1 per square foot.

How deep should blown-in insulation be in attic?

about 10 to 14 inches
The recommended level for most attics is to insulate to R-38 or about 10 to 14 inches, depending on insulation type.

What are the cons of blown in insulation?

Cons

  • This type of insulation requires professional installation.
  • Installation projects can be very messy.
  • The weight of blown-in cellulose can cause ceiling sag.
  • Damp blown-in insulation can promote fungal growth.
  • The material becomes very problematic when wet.

Is rolled insulation better than blown?

The Differences Between Blown-in and Rolled Insulation In terms of R-value, they tend to be equal, although you can choose rolled insulation with varying R-values depending on your needs and your budget. The lower the R-value is, the less effective it will be as insulation – although it will be cheaper as well.
