Good thermal insulation is the key to high comfort and saving money. To keep your home air-tight you can do some basic things. Some are major and can require hundreds of dollars, while others can be very easy to achieve and cost pocket money. All these measures will pay back over a certain period of time through lowered energy bills.

Thermal insulation. Newly constructed homes come with built-in insulation walls which make them energy-efficient. In some older homes, there is either no thermal insulation, or it may be in a poor condition requiring replacement. Wall insulation can be added to your home as a coating of cellulose, styrofoam, fiberglass or spray foam which is attached on your walls, roof and floor.

Measurement for thermal insulation resistance and represents its actual “power” to keep your home warm. For example: Styrofoam insulation has an R-factor of 4 per inch, while cellulose has 3.7, and is a bit more expensive, but is environmentally friendly. Sprayed polyurethane foam is even more efficient with R-factor of 6 per inch, but is also the most expensive.

Note that more of your heat is lost through the roof than through the walls, so that is where you need to put highly energy-efficient insulation materials.

Windows and Doors. Before you move to a new home, it’s a good idea to check the state of its windows. Good windows fit well, don’t allow air leaks and still have dehumidified and decompressed air between its glass panes. If you are able to see moisture inside the glass panes it means the air creeped inside and such a window needs replacement. Same goes if window fittings are so bad that you can’t effectively open or close the window. Cutting-edge windows feature insulation gas such as argon between their glass panes and their use in areas with extreme temperatures is highly recommended. No matter what your windows are like, curtains, blinds and shadings will always help a bit and add to their insulation capabilities.

Another things you can do include tasks known as “winterization”. These include installing some inexpensive add-ons to your doors and windows. Weather-stripping can be added to improve door and window sealing, window insulation films you can buy or order for cheap can be added to glass panes tweaking their insulation ability. Put draft seal tapes to the bottom of any doors to the outside. These inexpensive features will especially protect you from strong winds which easily expose weaknesses of your home’s thermal insulation.

All the measures mentioned here should be applied jointly for maximum effect. A good and new thermal insulation coat won’t help much if your windows are decrepit. Major insulation tasks may be costly, but the money you spend on that always pays back over time.

There are some government programs that provide assistance for insulation and weatherization. The U.S. Department of Energy (DOE) Weatherization Assistance Program provides grants to states, territories, and some Indian tribes to improve the energy efficiency of the homes of low-income families.
