The Importance of Insulation Inside of Your Home
Insulation in your home provides resistance to heat flow and lowers your heating and cooling
costs. Properly insulating your home not only reduces heating and cooling costs but also
According to the North American Insulation Manufacturers Association (NAIMA), 90% of
single-family homes in the U.S. are under-insulated, so chances are high that your house
could use some work. Homes built prior to 1960 are particularly vulnerable.
Insulation is the best and first solution to a warm, healthy home environment for families of
all types and installing home insulation is also one of the best things you can do to lower
power bills to make your home more energy-efficient.
Why Insulate Your Home?
A well-insulated home will provide year-round comfort, and cost less to heat and cool your
home. Insulation also helps regulate condensation and reduce noise levels. We can all
agree that a well-insulated house is more comfortable and it can also be cheaper to heat,
contain less mould and mildew, and be less conducive to allergy-aggravating dust mites.
Here are our 5 top reasons to insulate your home:
1. Greater energy efficiency along with lower energy bills.
2. The impact from windows is limited if the rest of the home isn’t air tight and well
3. Energy efficiency is becoming increasingly important to homeowners and tennants.
4. Insulating your home helps reduce outside noise and noise between rooms and other
5. Insulation can promote a healthier home espeicially if you have family members
prone to asthma and other breathing difficulties.
How Insulation Affects Your Energy Bill
The EPA estimates that the average homeowner can save 15% on heating and cooling costs
which equate to around 11% of total energy costs, just by adding insulation in crawl spaces,
attics and basements. For most people, that is approximately $200 in savings per year. In
colder parts of the country, savings increase up to 20%. With these statistics, it is easy to
understand the savings you would obtain over time once investing in the insulation of your
On average heat loss is lost through the following ways in your home:
● 33% of heat loss happens through the walls.
● 26% of heat loss is via the roof.
● 18% through gaps in and around windows.
● 12% via ventilation & draughts.
● 8% of heat loss is through the floor.
● 3% of heat loss is through gaps in or around the door.
How Insulation Works
To understand how insulation works it helps to understand heat flow, which involves three
basic mechanisms – conduction, convection, and radiation.
The way heat moves through materials, such as when a spoon placed in a hot cup of coffee
conducts heat through its handle to your hand.
The way heat circulates through liquids and gases, and is why lighter, warmer air rises, and
cooler, denser air sinks in your home.
Radiant heat travels in a straight line and heats anything solid in its path that absorbs its
Most common insulation materials work by slowing conductive heat flow and convective heat
flow. Radiant barriers and reflective insulation systems work by reducing radiant heat gain.
To be effective, the reflective surface must be in contact with an air space.
Regardless of the mechanism, heat flows from warmer to cooler areas until there is no
longer a temperature difference. In your home, this means that in winter, heat flows directly
from all heated living spaces to adjacent unheated areas. Heat flow can also move indirectly
through ceilings, walls, and floors. Basically, wherever there is a difference in temperature.
During the coller seasons, heat flows from outdoors into the interior of your home.
To maintain comfort, the heat that is lost during winter must be replaced by your heating
system. During summer, the heat gained from the temperature must be removed by your
By properly insulating your home, the transference of these temperatures will decrease
creating a comfortable environment.
4 Types of Insulation for Your House
This is the most common form of insulation. Fiberglass is available in either loose fill or batts.
The best part of insulating your house this way is that this is more cost effective and also the
easiest way to provide insulation for your home. Fiberglass insulation also prevents your
house being damaged from any dampness and condensation. This material is
non-flammable and further protecting your home.
Fiberglass insulation is done mainly between joists, beams, and studs.
It is important to note that fiberglass should be handled by a professional as the particles can
affect your lungs and skin. It is best to remain away from your property during installation.
Spray Foam Insulation
Spray foam insulation is installed with aid of spray holders. Foam is ejected as spray from
the containers in specific places of the house.
Spray foam insulation is best placed between new wall spaces, unfinished attics or existing
walls. Although the foam is sprayed using spray holders, it can also be applied in large
quantities, using a pressure spray.
Mineral Wool Insulation
Mineral wool insulation is also known as rock wool insulation. This is almost similar to
fiberglass insulation and material. Mineral wool is easy to install and comes in loose fills,
which can be poured directly from bags or be blown to a certain area. Mineral wool insulation
material can tolerate higher temperatures. The house also remains soundproof when
insulated mineral wool.
If you are looking for an organic way to insulate your home, cellulose insulation will be the
closest option for you. Celluloseinsulation is typically made from recycled paper, mainly
newspapers and sometimes cardboard and other types of papers. This insulation material
comes in loose fills.
Cellulose insulation materials have to be treated with chemicals to make them better in
protecting the home from moisture, heat, and pests. However, it should be remembered that
as this kind of insulation absorbs moisture and can get damaged with time. With this damage
and with the 5 yearly recommended replacement, the overall installation costs for cellulose
insulation for your home will be much higher as compared to the conventional fiberglass
Is Upgrading Your Insulation Worth It?
For most homeowners, upgrading an under-insulated home is well worth the expense. It’s an
improvement that will pay off in both reduced energy bills and improved home value. There
is also the added benefit of reduced greenhouse gas emissions. Therefore we recommend
to take the time to evaluate and develop a plan that’ll leave you with a properly sealed and
