Why is efficient home insulation good for saving energy?
Almost half of your electric bill goes to regulating the temperature of your home. Thus if you want to save on your electric bills, the best place to start is your homes insulation system.
Insulation is important to minimize or eliminate the heat exchange/loss inside your house. Good insulation keeps the interior warm during winter and cold during hot summer days. A well-insulated house allows your heating and cooling systems to effectively work as needed. Proper insulation can save as much as 10% of your monthly electric bill.
Meanwhile, if your house has leaks or if it has insufficient insulation, air will pass through; and heat exchange will occur on areas where insulation is inadequate. This results to heat loss. And because a house with leaks and insufficient insulation requires more power to regulate its temperature, energy consumption will likely increase.
Where to insulate?
Areas of the house including the switches, power outlets, plumbing fixtures, walls, windows, doors, ceilings, floors, basement, crawl spaces and attic should be properly insulated.
