If you are living in a region that is perpetually cold, or where the winters are particularly harsh, then you must be familiar with insulation. Air naturally tends to move from warm areas toward colder areas, and this natural movement is what the method of insulation restricts. Therefore, during winters, insulation prevents the cold air from sneaking into the house through ceilings or walls, and keeps the interiors warm.

There are certain insulation products that are more effective than others, and they also reduce the energy bill considerably. These are the products you can use at home to make your environment more comfortable and healthy:

The most common materials used for the purpose of insulation are fiber glass, rock wool bats, blankets, rigid or blown foam boards, and cellulose.


Fiber Glass consists of extremely fine glass fibers and is one of the most abundant insulation materials. It is commonly used in blankets and loose-fills. Loose-fills can be poured in between ceiling joists or added behind existing walls.

Cellulose Insulation Material is made from recycled paper products such as newsprint, and has a very high recycled material content, ranging from 82-85%. Cellulose insulation is used in both new and existing homes, as loose-fill in open attic installations and dense packed in building cavities such as walls and ceilings.

Foam Boards can be cut in a way to fit in between new construction wall studs or glued directly into foundation walls.

Insulation Facings are fastened to insulation materials during the manufacturing process. Common facing materials include Kraft paper, white vinyl sheeting, and aluminium foil. All of these materials act as an air barrier or a vapor barrier. The severity of the climate and where you are installing the insulation in your home will determine what type of facing you will need.

Natural Fiber Insulation Materials such as straw, sheep’s wool, cotton, and hemp are used as insulation materials in houses that prefer to go the natural way, which is also the cheaper way of restoring the warmth in your home.

One thing you must keep in mind before deciding upon the insulation materials is the R-value, the measure of insulation, which is basically its resistance to heat flow. The higher the R-value, the more insulation it provides. For example, the R-value of Fiber Glass ranges from R-11 to R-15 inch. There are specific amounts of values that are required for specific homes, depending on where they are located.
