External Wall Insulation Can Lead to Energy Efficiency

The installation of insulation acts to make for energy efficiency by reducing the effect of external influences and weather conditions that can greatly affect temperatures inside any living space.

A home is composed of walls, and a roof that is exposed to the elements and proper insulation in both these areas can go a long way to increasing the comfort of living in a home. The areas of external walls in a home are often far greater than the roof area, and proper wall insulation is, therefore, a must for air conditioning or the heating of a home. This insulation can be added to a wall with the aid of a framework and fixtures. The insulation makes for a cladding element that if it fixed on the exteriors of a home must be able to resist the weather.

Many homes have cavity walls in which the air layer between walls already acts as an insulator. The insulation properties can be augmented by filling the void or cavity with foam insulation. This method of wall insulation can also be used to carry out the insulation work inside a home, by injecting the foam into the cavity that is available between walls and any drywall finished surface. The insulation being inside the home does not have to be separately rendered or treated for weatherproofing the wall.

Insulating the walls of a home can reduce energy costs by as much as forty percent, and will also help to retain the created temperatures in a home for longer periods. At the same time, care must be taken to see that there are no other points of leakage from doors and windows that are not properly sealed or do not close properly. Installing insulation on the external walls may at times need permission from local building authorities.
