Have you ever noticed that older homes don't seem to have
the same warmth as newer ones do? They may seem a little draftier, and outside
noises aren't filtered as well as in newer homes. A common reason for this is
the home is poorly insulated, or worse, not insulated at all! Walls that have poor insulation
no insulation are not doing anything more than keeping the outside out, and the
neighbours from seeing in! The energy lost from a home in this situation is
substantial. You may think that there is nothing you can do to remedy this
situation. Possibly you have been told that you are going to have to remove the
walls on the inside of your home in order to insulate the wall cavities. These
ideas couldn't be further from the truth. There are a few solutions to this
problem however blown-in insulation is by far the easiest.
What is blown-in wall
Blown-in wall insulation utilizes a material called
cellulose. Cellulose is made up of recycled newspaper that is grinded into tiny
pieces. It is then treated with borates to make it fire retardant, mold
resistant, and pest repellent. This preparation is then packaged in
vacuum-sealed bags for ease of transportation, space saving, and user handling.
There are several brand names and R-values available from which to choose. Once
the packages arrive at the home where they are to be used, they are cut open
and broken up in to a blower machine that is used specifically for blowing in
How is blown-in
can be installed in attics and wall cavities. In older homes
that are lacking adequate wall insulation, the process of blowing in insulation
is a job that should be undertaken by a reputable, professional insulation
installer. These professionals have been trained to ensure proper installation
and to avoid any damage to the interior walls and wiring that is contained
within them. A thorough site inspection is undertaken and a plan is drawn up to
identify obstructions such as wiring and pipes. These precautions are vital to
ensure that no damage is done while drilling holes as well as to guarantee that
the space above and below larger pipes is being filled with cellulose. Some
wall cavities contain pipes for instance that will go through the middle of
that cavity. Without properly inspecting the site, and making note of this, the
walls may not be properly insulated.
Once the obstacles are determined, the installer will drill
holes large enough for the installation hose in the exterior walls. In the case
of vinyl siding, a few slats can be removed in the area where the holes will be
drilled and then replaced once the job is done. For a wood-sided house, the
holes will be filled with wood plugs and then sealed. Bricks can be removed and
replaced, or holes can be drilled through mortar in the case of a brick home.
The hose is then inserted into the hole and the insulation is blown into the
wall cavity. Some installations start and the top of the wall and others go
from the bottom up. The cellulose will stop moving through the hose once the
cavity is full. Once all of the walls are filled, the installer will close the
access holes, repair the intentional damage, and do an interior inspection for
cellulose that may have come through. The installer should then explain to you
what they have done, and show you that the holes have been repaired. All you
have to do now is enjoy the comfort, and quiet of your newly insulated home.
FAQ Attic Insulation
Q. What material do you use for the attic?
A. The attic insulation of choice for Insta Insulation is cellulose. It has a higher R-Value, higher density gives it an ability to deal with air flow better than fiberglass. The fact that cellulose wicks and can deal with moisture makes it the product we recommend. Very rarely will you find an attic with mold that has cellulose in it. Cellulose in most cases is a bit more expensive than fiberglass to install but well worth it.
