Blown In Home Insulation

Of the top five reasons for using blown in insulation, the first is that it is adjustable. You can vary the R-value by how much insulation you choose to use. Blow in so many inches for an R-value of 15, and so much more if you would rather have an R-value of 38. Another reason for using blown-in, is that most products use virgin materials, that have lowered the chance of allergies. A tighter seal can be gotten with blown-in insulation, because it fills all of the cracks, and empty spaces. The installation is fast, and since everything is filled in, it is very energy-efficient.

Installing blown-in insulation is easy on a newly framed house. All that is done is staple a netting over the exterior wall studs, then cut a few little holes, stick in the hose, and fill up the wall cavity. The material blown in sticks to the studs, and completely fills all of the empty spaces. Cover up the walls with a vapor barrier, and drywall and you are done. To blow in the ceiling insulation, you drywall the ceiling first, then climb into the attic area and blow it in. Much more difficult on an older home, because the wall covering will have to be removed first. Then the procedure is pretty much the same. If you have a really old house, with no insulation, you can just cut a hole in the wall, and blow it in, then cover up the hole.

To begin with, the cost of blow-in insulation is more expensive, but it is much more efficient as an energy saver. With the lower heating costs, and a more comfortable living, having blown-in insulation makes a lot of sense.
