The principle under which insulation works is called conduction, which is the way heat moves through different objects. If you’ve ever picked up a cup of hot coffee and felt the heat through the porcelain, that’s conduction. Normally, the kinds of materials that make up the walls and ceilings of your home are quite conductive. But insulation, regardless of the type, is designed to restrict the flow of conduction, helping to keep heat (and cool air as well) inside your home.
Heat radiates out from your home in all directions, which is why you need insulation in all of your walls. But heat tends to rise, which means that your roof and attic are the most important parts of your home to insulate. The more you can place above your head, the cozier your home will stay. Your heater needs to replace the heat lost through your walls, and your air conditioner needs to do the same thing with cool air. The better the insulation, the less hard they have to work and the lower your monthly energy bills will be.
Insulation’s resistance to conduction is measured by its R-value, which measures it thickness and consistency as wells as the specific materials with which it is made. The higher the R-value, the better the insulation and the more effectively it will keep hot and cool air inside your home.
By understanding how insulation affects your home’s temperature, you understand the savings you are getting in exchange for your up-front investment. For the installation of insulation in Phoenix, AZ, Goettl Good Guys Air Conditioning is here. Give us a call today to talk about your options!
