If you are suffering through high energy bills again this winter, there’s a good possibility that your home doesn’t have enough insulation. Here is some information to help you understand why insulation is so important, and how to know if you have enough.
How Does Insulation Work? Insulation between the walls, under the floorboards and in the attic helps trap heat in your house and prevents cold outside air from leaking in. Older homes that were built before the importance of insulation was understood can cost up to $1,500 a year to heat. Even newer homes often have inadequate insulation. If you have a concern, it is crucial to get a professional evaluation of your insulation. Better insulation could help slash up to $600 a year off heating and cooling costs.
Do I Need More Insulation? A quick and easy way to figure out if you need additional insulation is to take a look at the floor of your attic. If the current insulation allows you to see the tops of the floor joists, you need more insulation. If the insulation already completely covers the joists, a professional can measure the depth and determine if it would be cost-effective to add more insulation.
The Passive House. Did you know it is now possible to build a super-insulated house? Also known as a passive house, its triple-glazed windows and active insulation all throughout the house mean it just needs body heat, the sun and heat from appliances in the home to heat it, plus a good ventilation system to keep fresh air circulating. At just 15 kilowatt hours per square meter per year in energy use, a passive house could see you spending a mere $100 a year on your heating bill!
