A home needs to be properly insulated from the roof down to the foundation. Most people focus on the insulation of the attic and ceiling, as those areas receive most of the heat from the sun. A home needs insulation in a number of other areas, however, for its occupants to live comfortably.
The following parts of the house need insulation to keep out the cold of winter and the heat of summer:
- Duct insulation – Ducts that are located in unconditioned spaces require sealing and insulation. This is often an issue in older houses. In newer houses, ducts are usually placed in conditioned spaces as a deterrent against energy loss.
- Exterior walls insulation – Insulating and sealing the attic will not be enough because the house will be cold and drafty in the winter and overly warm in the summer. Insulating the exterior walls will provide additional protection against the elements. Exterior walls could be best insulated using blow-in insulation.
- Above-garage insulation – If there are rooms above unheated garages, you will need to insulate the floors on top of the garage so you have a barrier from the outside air. Before installing insulation, it is necessary that all sources of air leaks are properly sealed to minimize contaminants from car exhaust and chemicals that might be stored in the garage.
- Foundation insulation – Properly insulating your foundation will make the rooms on the lower floor of the house more comfortable. Foundation insulation will also help prevent moisture seepage, radon infiltration, and insect infestation. New homes are usually built with an insulated foundation.
- Basement insulation – Basements can be cold and uninviting, but insulating the walls of your basement allows for a warm and welcoming living space.
- Crawl space insulation – Insulating the crawl space under the house can improve the moisture and temperature controls in the house.
Investing in good insulation can keep the temperatures in your home at optimal levels and help you save on energy costs.
