Insulation is any material or substance that provides a high resistance to the flow of heat from one surface to another. The single idea or premise that insulation is based on comes from heat moving from a warm area to a cold area. In the warmer times, heat tries to enter the house and on the colder days, the heat tries to escape. With vagaries like these, the purpose of insulation is to regulate the temperature by reducing the pace of the process. One way for some effective insulation is the method of absorbed insulation. These use materials such as aluminum foil and polyethylene foam which can be helpful in preventing the accumulation of cold and hot air and reducing heat transfer.

There are other forms of regulating the temperature too, in the insulation field. These are called the insulation boards. There are three forms of foam board products under several manufacturers names. They include extruded polystyrene, expanded polystyrene and foil faced or polyisocyanates unfaced. These boards are explained in detail below:

Extruded Polystyrene Foam or XPS is popularly known as the pink board or the blue board in edge profiles and in different thicknesses. This board is one of the most widely used insulation boards in the residential construction industry. XPS has an R value (measure of thermal resistance) of 4.5 to 5.0 per inch thickness. It is reasonably priced, light and easy to use. The product can be used to insulate the outside of foundation walls and even under the slabs of concrete.

Expanded Polystyrene Foam or EPS is the least used, cheapest quality foam available in the construction industry. The product may have an R value of 3.6 to 4.0 inches thick. This type of insulation boards is very similar to the foam which is used for packing “peanuts” and is used in insulated concrete form also known as ICFs.

Polyisocyanurate also known as polysio, is usually observed in all kinds of commercial and more recently with residential building projects. It has an R value of 7.0 to 8.0 inch of thickness. It also has a foil faced. The foil makes it excellent for insulation boards when radiant heat is involved. It is also the most expensive board, amongst the three.

Although foam boards are much more expensive compared to other insulation materials, such as cellulose or fiberglass, it is mostly used in places where space limitations are encountered. Another reason for preference is, it is three times thicker than most of the insulating materials and because it has high R values. Also with materials such as polystyrene sheets, give a more peaceful and subdued home since, it prevents the entry of unnecessary noise. The house can have a sobering effect and can drastically reduce the cost of electricity. There are a number of stores both on-line and off-line that one may visit for the precise boards for the perfect fit!
