Many homes are built with unfinished
basements. Unless you have specified to your new homebuilder that you would
like it finished, and pay the added costs to do so, yours will be unfinished as
well. Finishing your basement is a do-it-yourself project that a lot of
homeowners take on themselves. The first thing you should take care of when
starting your basement renovation is insulating the walls. There are many types
of insulation from which to choose.
Fibreglass insulation is sold
in rolls or batts. It is one of the older forms of insulation. This cloth is
generally more affordable, and easier to install as a do-it-yourself project.
Fibreglass is made up of billions of strands of glass woven together. This
allows for a greater surface coverage area at lighter weight. It is
non-combustible and non-absorbent. The drawback of this insulation is that you
should be very well protected when working with or around it. The tiny pieces
of glass that make up the fabric can become airborne when is it moved around making
it possible for them to be inhaled. These strands are also so fine that they
get in to your skin and can cause irritation, itching and rash.
Blown-in insulation is made of
either fibreglass or cellulose. It comes packaged in large blocks that are
broken down in the insulation blower. A large tube that is attached to the
blower is directed to where you want the insulation to go. The benefit of this
insulation is that it can be used over existing insulation in your attic to
increase the R-value. Its small particles allow for it to settle in to gaps and
crevices giving it the ability to cover a large area. One con associated with
blown-in insulation would be the clean up as the small pieces can fly around
and settle in other areas.
Foam board comes in sheets much
like drywall. It is available in several thicknesses and R-value ratings as
well. Common uses for foam board insulation are basement walls and on top of
concrete basement floors between other types of flooring. Foam boards can be fitted between wall joists in
your basement and will offer an excellent airtight barrier. This material
can be used on the exterior of your home as well. It is a superior weather
barrier due to its impermeable nature. Foam board insulation is made up of tiny
air bubbles contained within a medium such as polystyrene.
foam is probably the most effective and certainly one of the most popular.
Spray foam is an expanding foam insulation that is sprayed onto the surfaces of
your home that you intended to have insulated. High-powered machines that
utilize compressed air propel the liquid foam through a nozzle to completely
cover the area specified. It instantly expands and dries into a hard air and
watertight seal. Its application can be used on the interior or exterior of
your building making it a very versatile choice. The installation of this
product is generally completed rather quickly, and certainly much quicker than
other insulation options.
All that you have to do now is decide whether
the insulation of your basement is something that you can take care of on your
own or if it is a job better left to the professionals?
FAQ Attic Insulation
Q. Is air sealing my attic more important than adding more insulation?
A. The answer is quite simple "NO". Although air leakage accounts for 40% of a home's energy loss, when you insulate your home with anything the home will get tighter and have less air flowing through it. This is exactly what happens when adding additional insulation to your attic. Cellulose by itself is a good product to upgrade your attic for air tightness and insulation. A layer of spray foam and then blown cellulose is the best but there is also an associated cost. A fiberous insulation will always work better when the airflow is slowed down or minimized around it.
