a plus, inc. can handle any type
of wall insulation that you might require.
How the insulation is applied
depends on whether it is new construction or an upgrade to existing walls.
For descriptions on applications
in existing walls, click here.
In new construction or additions,
every type of insulation is available to you.
You can have regular fiberglass
batts, cellulose sprayed on the wall and of course, the most popular choice for
best energy efficiency spray foam.
Spray foam insulation has been
used for many years as well, but until the last couple of years it has not been
as widely used in new construction because of the cost. People are finally
deciding that the extra cost during construction is more than paid back in much
lower energy costs.
As you can see in the sample
pictures below, we can spray in existing wall that has the drywall removed or in
a wall that has just been framed. Our trucks with specialized equipment
can pull up to your jobsite, and spray all of the areas that you need taken care
of in the attic, walls or crawl space / basement.
Fiberglass batts insulation is
the oldest, least expensive and least efficient of the insulation choices. Most of
the newer batts have a certain amount of recycled content in them as part of
green programs by the different manufacturers. These batts are easier to
install, and as part of an addition project, is something that an experienced
do-it-yourselfer can tackle.
One of the biggest draw-backs to
the batts type of insulation solution is that it does not address the problem of air
infiltration. This is where air moves through the exterior surface of your
home through cracks and holes that we don't even know exist. This has as
much to do with keeping your home comfortable as the insulation itself, but is
mostly overlooked because is costs a little more.
Sprayed-on cellulose has been
used for many years. Cellulose is a better sound deadener than fiberglass
and does a better job at closing off the air-flow through the wall cavity but
still allows a large amount air to come through the penetrations.
For those of you that are
interested in recycling and green products, cellulose can contain upwards of 80%
recycled content in it's composition.
