How to Choose the Correct Ceiling Insulation
It is important that one installs the right kind of attic insulation because the correct insulation can drastically reduce the electricity bills of heating and cooling the house. It is worth acknowledging that insulation would also make your home warm and comfortable and also create a steady in-house atmosphere in addition to reducing our home’s energy consumption.
In order to determine the right insulation, one needs to consider the R-value of the insulating material. The purpose of insulation is to prevent gaining heat on a hot day and trapping the warmth during cold conditions and is measured by the R-value. The R-value is the measure of how competently an insulator resists the transfer of heat between surfaces. This value varies depending on the nature, density and thickness of the material used. Therefore, a material with a high R-value will be more efficient than a material with a low R-value.
There exist several different types of insulation materials with the most common ones being foam, fiberglass and cellulose. There are also a variety of insulation types ranging from loose fill, batts, spray board, vapor barriers, and rolls with rolls being the most ideal for ceiling floors. In determining the type of insulation required, one needs to consider the existing insulation and the desired R-value..
One is also advised to install vapor barriers in the outer frame of the house to prevent accumulation of moisture in the ceiling. If this measure is not adhered to and the moisture is allowed to circulate freely on the inside and outside of the ceiling, the moisture will weaken the insulation material and make it lose its R-value. In addition, mold and rot will develop over time which will adversely lower the strength of the house frame
When calculating the amount of insulation required, you will have to determine whether your house is already insulated, measure the total area that requires insulation and decide on the best type of insulation to use.
If you happen to have insulation already, gauge its industrial standards by looking at its R- value with the higher R-value promising better performance. Next, one needs to measure the length and width of the area requiring insulation and multiply the two measurements to get the square footage of the ceiling.
While determining the type of insulation used, bear in mind that fiberglass insulation is assessed by the number of rolls required and can be installed by the homeowner hence saving on labor costs. On the flipside, blown-in insulation, though not tedious, requires specialized equipment and may turn out to be a little more expensive than fiberglass. While insulating, remember to insulate the outer walls and crawl spaces too as these spaces are most vulnerable to heat transfer.
