Insulation is a general term used to describe products that reduce heat loss or gain by providing a barrier between areas that are significantly different in temperature. Insulation therefore reduces heat leakage in winter and protects your home from getting too warm in summer.
Insulation also acts as a sound barrier by reducing the level of sound transmitted from one room to another via partition walls or ceiling voids. which in turn contributes to the development of quieter living environments.
Insulation is the easiest and most inexpensive way to increase the energy efficiency of a residential home or commercial building. An energy efficient building is a cost-efficient building.
Take for example a residential home. Studies have shown that a home which does not have proper insulation will leak heat during winter. 30% of heat, heat that a homeowner is paying for, will be lost through the roof, 10-15% through windows, 20-30% through walls, and 10- 15% through floors. A properly insulated home will significantly reduce heat leakage, meaning your heating and cooling units will not have to work as hard as they would if your home was not insulated.
Studies show that a properly insulated residential home will be cooler in summer and warmer in winter by an average of 8-12º C. This results in a comfortable living environment in addition to energy cost savings.
Indeed, properly insulated homes will not need as powerful a heating/cooling unit as those that are not insulated, and so there is a saving there as well, as smaller and therefore less expensive units can be installed.
Insulation also provides exceptional acoustic performance resulting in quieter living spaces. This means the level of noise transferred from the external environment and/or adjacent rooms will be reduced, thus improving the acoustic ambience of your home.
