For an optimal energy efficiency, your house must be properly insulated from the roof down to its foundation. In addition to insulation, consider air leakage and moisture control in each area of your home. Also, if you leave in an area with termites, you will have to keep in mind how termite protection can affect the choice and placement of insulation in your house. If you are trying to get your home insulated, read more here on this website so you know what is the best type of insulation for you and your home and what are the things that you can be insulated.
Here are some of the places you can insulate in a house
Batt or loose-fill insulation is typically installed in attics. Usually, loose-fill insulation is less expensive to install than batt insulation and provides better coverage when is installed correctly. If you want to find out if you have enough attic insulation, measure the thickness of the insulation. If it is less than R-30 (11 inches of fiberglass or 8 inches of cellulose), you could probably benefit by adding some more. Before insulating your home, see if there are any air leaks and also make ceiling and other repairs. If the attic is located in a conditioned part of your house, remember to insulate an air-seal your attic access. You must insulate and air-seal knee walls in your home as well. Keep in mind that if you are building or remodeling a new home, make sure any attic decking provides additional storage space for heating or cooling unit.
If the ducts in your house are in unconditioned space, insulate and seal them. If you are building a brand new house, you should place ducts in a conditioned space to avoid energy losses associated with most duct systems.
Cathedral ceiling insulation
Insulating you cathedral ceilings will allow ceiling temperatures to remain closer to room temperatures that provide an even temperature distribution to the house. Cathedral ceilings must provide space between the roof deck and home’s ceiling for adequate ventilation and insulation. This process can be achieved through the use of truss joists, scissor truss framing, and sufficient larger rafters. Foil faced batt insulation is usually used in cathedral ceilings because it provides the permeability rating often required for use in ceilings without attics.
Exterior wall insulation
If your attic has enough insulation and proper air sealing, but your home still feels cold and drafty in the winter or too warm in the summer, you will need to add insulation to the exterior walls of your house. This is more expensive, and it usually requires a contractor, but it may be worth the cost.
Insulated floors above unheated garages
First, seal all possible sources of air leakage. This strategy has the added benefit of minimizing the danger of contaminants (solvents, paint, gardening supplies, etc.)
A properly insulated foundation will keep below-grade rooms more comfortable and will prevent moisture problems, insect infestation, and radon infiltration.
Now that you know the parts that can be insulated and some of their benefits try to contact a qualified contractor to install the type of insulation required to your situation. This video provides the advantages of external wall insulation for your home.
