Understand what insulation is and what it can do for your household.

Understanding insulation and its benefits will give you a better chance of getting the right insulation supply for your house or building.

Insulation serves as a barrier to heat flow. It is needed in keeping the home warm during the winter season, and cool during the summer. Good insulation not only makes a home comfortable to live in; it can also cut cooling and heating costs by up to 50 percent. It ca reduce greenhouse gas emissions as well.

Insulation can also absorb sound, lessening the unwanted noise coming from audio equipment, appliances, and other sources. A well-insulated home can also aid in moisture control, as everyday activities like bathing, washing and cooking can add moisture to the air in the form of water vapor.  In turn, vapor can be trapped inside the walls resulting to growth of mold and mildew which poses a potential health issue and damage the home.

Learn More About R-Value

When shopping for insulation supplies you will likely be asked about R-value. This is the measure of the ability of a material to resist heat conduction. Simply put, the greater the R-value of a material the better it acts as an insulator.

All values assigned to insulation supplies are based on specific thicknesses. The R-value is often noted on the packaging. Reducing the thickness of insulation reduces the ability of the material to resist conduction.

When buying an insulation supply, check not only the R-value but also the price per square meter. You should also ask if the material should be installed by a professional, or you can do it yourself. There are some insulation supplies that require the use of protective clothing and mask, which you may not have.

Determine too, whether or not the supply suits a certain application and fits within the space in your house. You should also ask for performance guarantees or test certificates.

Know where to install insulation.

The attic is the easiest place to get into and determine the current insulation condition of your home.  The attic needs up to 19 inches of insulation for energy efficiency.  To know the existing insulation, slide a yard stick or tape measure. If the insulation is not 19 inches deep, then you need to add more insulation in the attic.

If there is not enough insulation in that part of the house, then there’s a good chance that your home is under insulated.  Adding insulation to areas which are under insulated as well as sealing air leaks should lower energy costs.

You can also check other parts of the house like the basement and crawl space. For the basement, check the rim joints and compare the depth with an R-value map for your area. For the exterior walls and floors,  you should first turn off the electricity before removing the electrical outlet cover to get a view of the exterior insulation.

In the garage, check if the walls and ceiling are adjacent to conditioned spaces.

Determine the type of insulation needed.

There are many types of insulation that you can choose from.  There is blanket-type insulation with materials like fiberglass, plastic fibers, and natural fibers. This is the most widely available type of insulation. These are used in unfinished walls, floors and ceilings. Installation of this type can be DIY.

Reflective system insulation is another type that can be installed DIY or without professional help.  Foil-faced kraft paper, polyethylene bubbles and plastic films are the insulation materials under this type. It can be used for ceilings, floors, and unfinished walls.

Most insulation materials however need to be installed by professionals. For example, concrete block insulation requires specialized skills and can be installed on unfinished walls and foundation walls.  In this type of insulation, a foam board is usually placed on the outside wall for a house that is being constructer, or the inside of the wall for existing homes. Doing so can control indoor temperatures.

Then there are the foam boards that can be used to insulate almost any part of the house from the foundation to the roof. Foam boards provide good thermal resistance, and reduce heat conduction. Some of the common types of materials that are used in making foam boards are polyurethane, polysterene, and polysocyanurate.

Generally speaking, professional help is essential in choosing and installing the right insulation supplies. But if you can’t get a qualified installer or you think you can do the installation yourself, get some guidance from the insulation material manufacturers.
