How Insulation WorksInsulation is a thermally resistant barrier which inhibits the migration of thermal energy into and out of the house. In simple terms: insulation blocks heat from entering the home in the summer and holds heat in during the winter.
The results are a cooler home in the summer, warmer home in the winter, and lower energy bills. It's that simple and it really works. Insulation is so effective that its cost is often paid for through energy savings in less than a year... and with the rising cost of natural gas and electricity, savings may come even sooner! |
Where insulation is installed?
Summer
During the summer the suns powerful rays radiate down onto our homes, the roof and walls heat up and the temperature in the attic can rise to nearly 170 degrees. This heat enters the home and causes things to become quite warm and uncomfortable. You then have two choices....turn on the air conditioning and watch the electric meter spin, or suffer with the heat.
Homeowners often complain of an air conditioning system that runs all day and never cools the house below 80 degrees. This is typical of a poorly insulated home, the heat is entering the home at about the same rate as your air conditioning can cool it. The solution is to reduce the heat-load and block the heat from coming into your home. Insulation installed in your attic and walls will dramatically reduce the amount of heat entering your home; the house stays cooler longer into the day and the air conditioning, when it does come on, runs much less often. When we insulate homes during hot days, customers often notice an immediate difference and frequently describe the feeling as though a huge shady cloud came over their home.
Winter
Insulation makes a huge difference in the winter, it's amazingly effective when it comes to retaining heat. Just as insulation can block heat from entering the home in the summer, it too works in the same way to keep the heat contained within the home during the winter. Homeowners frequently complain of cold homes and furnaces that run continuously. This is because the heat is escaping about as fast as the furnace can produce heat. Once insulated, heat is retained within the home for hours longer. The result is a warmer home that uses much less energy to stay warm.

Why insulation goes on the floor of the attic and not on the underside of the roof?
Attic insulation should be installed directly on the floor of the attic, which is your ceiling and this is because you are heating and cooling the area below the ceiling, this is referred to as conditioned area while the area in the attic itself is considered unconditioned area.
In the winter you want to retain the heat in the home where you live, you don't want heat to rise through the ceiling. If you were to put insulation under the roof, then heat would wastefully rise into your attic area where it would be readily lost through attic ventilation.

During the summer it would seem like a good idea to also insulate the underside of the roof in an effort to keep the attic cooler, but the roof rafters are limited in being able to hold either R13 or R19 rolled fiberglass, which is not enough to entirely block the heat from coming into the attic; by the afternoon the attic will get quite warm/hot and then the insulation installed on the roof rafters will serve to hold that heat in over night and the attic insulation on your ceiling won't be able to cool down over night. Also, your roofing material will get hotter because the heat won't be able to ventilate underneath, most roofing warranties are void unless you have adequate attic ventilation.
Our feeling is that a very well insulated attic (insulation installed on the floor of the attic against the ceiling), brought up to R38, should sufficiently work to keep the inside of the home comfortable in both summer and winter. To further help in the summer you could install additional attic ventilation to allow heat to escape and keep the attic cooler. For homeowners who really want some form of additional insulation under their roofing, we can install radiant barrier which will help reflect/refract heat energy and serve to keep the attic cooler in the summer and even retain more heat in the winter. |
