How Insulation Works
You need insulation in your home to provide
resistance to heat flow. The more heat flow resistance your
insulation provides, the lower your heating and cooling costs.
Heat flows
naturally from a warmer to a cooler space. In the winter, this
heat flow moves directly from all heated living spaces to adjacent
unheated attics, garages,
basements, and even to the outdoors. Heat flow can also move
indirectly through interior ceilings, walls, and floors—wherever
there is a difference in temperature. During the cooling season,
heat flows from the outdoors to the interior of a house.
To maintain
comfort, the heat lost in the winter must be replaced by your
heating system and the heat gained in the summer must be removed
by your cooling system. Properly insulating your home will
decrease this heat flow by providing an effective resistance to
the flow of heat. An insulation's resistance to heat flow is
measured or rated in terms of its thermal resistance or R-value.
Adding Insulation to an Existing Home
Unless your home was specially constructed
for energy efficiency, you can usually reduce your energy bills by
adding more insulation.
 Many
older homes have less insulation than homes built today, but
adding insulation to a newer home may also pay for itself within a
few years.

How much Insulation do
I need?
Today’s standard building code has
recently been upgraded to R-38 in the attic. The thicker your
insulation, the higher the R-value and comfort level, but there
comes a point where additional material will not serve to provide
additional performance….call us for a free consultation.
No matter what kind
of insulation you currently have in your attic, one quick way to
determine if you need more is to look across the span of your
attic. If your insulation is just level with or below your ceiling
joists (i.e. you can easily see your joists), you should add more.
 It
is important that the insulation be evenly distributed with no low
spots, sometimes there is enough insulation in the middle of the
attic and very little along the eaves.

Radiant
Barrier Reflective Insulation
Studies have shown that up to 93% of ceiling heat gain in summer
months occurs from radiant heat transfers from attics heated by
radiant energy from the sun. Roof shingles and decking
absorb radiant heat generated by the sun and transfer this heat
into attic spaces heating up existing insulation. Once this
existing insulation meets its saturation point, it then radiates
this heat to all surfaces within the interior of the home
(ceilings and walls). Radiant barrier reflective insulation
products BLOCK almost ALL of this radiant heat.
Radiant barrier
reflective insulation can reduce attic temperatures by up
to 30 degrees when installed to the underside of roof
rafters. Lowering attic temperatures provides a significant
benefit by reducing air conditioning loads and energy usage. Attic
foil insulation radiant barriers can also reduce heat transfer
from attic to living spaces by up to 50%, extending the life
of your air conditioner while increasing home comfort.
 Having
both a radiant barrier & conventional attic insulation, is a
perfect combination. Think of a radiant
barrier as your defense in
keeping the summer heat out of your attic and thus your home,
while ceiling insulation keeps the cool air in your home.

Cooler in the Summer AND
Warmer in the Winter!!!!
The attic is by far the most critical area of your home to have insulated. Properly insulating and air sealing your attic
will help reduce your energy bills.
Money in your pocket!
Dollar-per-value, attic insulation is unbeatable. Typically paying
for itself within one year, it is perhaps the best money you’ll ever
spend on your home. It pays for itself and then continues to save
you money. Not just an improvement….an investment!

Wall Insulation
Most homes built
before 1972 do not have insulation in the walls. Properly insulated exterior walls in your house
will not only increase comfort but also help you save on heating and
cooling costs. For energy savings, you can add insulation to your
walls in an existing house. Wall insulation also can help quiet out
side noises such as traffic and airport noise.
Floor
Insulation
Heat loss through an un-insulated floor over a vented crawl space
can be significant. The trend for hardwood floors with out
carpeting, makes under floor insulation almost mandatory. In
addition to comfort, you can save many dollars in heating costs each
year by insulating under floors on homes with raised foundations.
Insulation
On Flat
Roofs
Foam boards—rigid panels of insulation—can be
used to insulate the roof . They provide good thermal resistance and often add
structural strength to your home. Foam board insulation sheathing reduces heat
conduction through structural elements, like wood and steel studs. A reflective
ultra violet coating is applied to further reduce heating loss and heat gain.
All Home Comfort can integrate your roofing
and insulation needs to offer the perfect energy efficient, solution for your
home.
The attic space needs to be well vented. Otherwise in winter moisture has no way
to escape. As warm air rises past the ceiling and insulation, it meets with cool
air and causes condensation. The moisture condenses on the underside of the roof
decking and drips back into the insulation. This leads to mold and mildew and
rotting in the attic space.
In the summer attics get very hot, sometimes over 140°. If heat isn't allowed to
escape the effectiveness of the insulation is reduced, and the life expectancy
of the roof components is reduced. Attic fans are an effective method of cooling
attic spaces. Attic fans are available in both solar and electric models and can
be roof or gable mounted.
Our Comfort experts can advise you on the correct options for your home.
OUR GUARANTEE
All of our work carries a lifetime
guarantee. The insulation is guaranteed to remain permanently
non-flammable. The insulation will not settle, pack or loose its
insulating value.
