50% of your home’s energy usage is related to your heating and cooling system and at least 25% of your cool or warm air can be lost because of improperly sealed windows, doors, and attics. Building codes for insulation did not even exist until 1980, so properties that were built before then most likely are not insulated. Regardless of when it was built, your home should still be checked for insulation to make sure it does not need replaced. How it was insulated then may not meet the code today. You should consider multiple factors before insulating your home such as your home’s location, dimensions, the climate, energy consumption, and your HVAC system. The right insulation installed properly allows you to stay cool during the summer and warm during the winter. Insulation is the most cost-efficient way to boost the energy efficiency in your home and it can save you up to 20% in your energy bills. It is an incredibly good investment that pays for itself in the long run. Adding insulation in the attic is one of the best ways to save further on your bill. If you live in an area where climates are hot most of the time, then an insulated attic is pretty much required to decrease the amount of heat coming through the roof of your home. If you are thinking of re-insulating your home, contacting a professional may be the safest option to ensure that everything is done correctly and efficiently.
