Insulation
Why Insulate
Home insulation is used to reduce heat gain (cooling season) and heat loss (heating season). Top Quality insulation, properly installed, keeps your home
�cooler� in the summer and
�warmer� in the winter. Studies show what we all know to be true. Air Conditioning and Heating are a major component of the home�s monthly utilities. Clearly, this makes your insulation selection one of the most important energy investments you can make.
By insuring that your attic has the recommended R. value of insulation you can reduce your utility electrical consumption costs. The purpose of the insulation is to reduce the
�transfer time� of heat from your attic area to the
�conditioned space.�
A law of science is that heat always transfers from a
warmer area to an area
which is cooler. This
�heat transfer� takes place in every home regardless of age or construction. The important point is the
�rate of transfer�. If you are able to slow-down the
�rate of heat transfer� by adding more insulation you will accomplish these three important steps.
1st � The air conditioning system will cycle less frequently thereby reducing the �run
time� of the A/C system, and save valuable Dollars $$$ on electrical expenses.
2nd � When the A/C cycles less this means that the area being cooled is maintaining the
�thermostat set-point� for longer intervals. This means that there is less fluctuation
(up & down) of the indoor temperature. The bottom line is a
greater degree of
indoor comfort experienced with a �more constant� indoor temperature.
3rd � With less cycling of the air-condition system you are
prolonging the life of you�re
A/C system. With less compressor � �starts� and �stops� the equipment life is
extended.
An increase in the R. Value will provide
Enhanced Energy Conservation. Insulation is rated in terms of thermal resistance to heat flow. The higher the R-value the greater the insulating effectiveness.
In the greater Houston and surrounding areas (Zone 4) the recommended attic insulation minimum is R.38 Insulation

Thermal and Acoustic Performance
Cellulose achieves an R.38 value in only 10.6�. Cellulose is a better inhibitor of heat as compared to fiberglass. Glass fibers do not block radiant heat as well as cellulose fibers. Cellulose also acts as a sound barrier to reduce sound transfer from outside the home. It has been tested extensively and carries the Underwriters Laboratories label.

See the graph below which illustrates how insulation works:
 |
(Summer)
This illustration depicts the �cool� room as the insulated room
(ceiling and walls). The room beside it has no insulation -
therefore heat transfers rapidly and the room becomes hot.
|
 |
(Winter)
This illustration depicts the �warm room� as the insulated
room (ceiling and walls). It is maintaining the �set-point�
temperature of the thermostat. The room beside it has no
insulation � therefore the room looses it�s �heated value,�
and the temperature drops to an undesirable temperature.

Although most homes have some attic insulation the average home has insufficient insulation. CenterPoint recommends a minimum of R.38 � 10.6� of attic insulation.
