First of all, it will keep you warmer especially in winter time. Whenever you use your heater at home, the warm air will always be diffused to every space possible. Warm air may also escape through your attic, and when this happens, the heater has to work harder to try to warm up a room. By insulating your attic even with only 18 inch thick of cellulose, you can reduce heat loss in very significant amounts attic insulation jupiter fl.
Second, attic insulation keeps your home cooler during summer time. The laws of physics will naturally make the attic much warmer during the summer season. And there is no way for the heat from the attic to go but down to your house. With proper insulation, the amount of heat penetrating to the attic can be reduced and make your house cooler even if it is hot outside. The air conditioning system may be allowed to take breaks in between cooling.
Third, insulating the attic also reduces convection. Convection happens when hot air rises and cool air goes down. In winter time, insulation helps prevent convection. In other words, it helps contain the heat inside instead of rising in the air and escaping from the attic.
The fourth advantage is the reduction of radiation. This only means that a warm area is heating up a supposedly cool spot in the house. In this case, the warm area is the attic. If you are thinking of what insulating material to get, consider the R-value. R is the value of heat flow resistance. In general, if you will compare two insulating materials, get the one with higher R value.
The fifth advantage is very practical. It will cut your energy bills to about 20% to 40%. This spells big savings. Of course, it will also depend on how efficient the installation is. There are some cases where the insulation is not properly installed in the attic such that heat still escapes from the gaps or uncovered areas. The insulation is rendered ineffective.
Sixth, not only will you cut on your monthly bills but you will also save money on taxes. You could be granted with tax credits in return for trying to conserve energy. So for example, if you are paying $2,000 in taxes, it is possible that you will be granted with $800 tax credit so you will only have to pay $1,200. That is a big amount saved on your attic insulation.
