What is Re-Insulation?
Increasing your home's insulation is one of the fastest and most cost effective ways to use a whole-house approach to reduce energy waste and make the most of your energy dollars.
A good insulating system includes a combination of products and construction techniques that protect a home from outside hot or cold temperatures, protect it against air leaks, and control moisture. You can increase the comfort of your home while reducing your heating and cooling needs by investing in proper insulation and sealing air leaks.
Sealing and insulating the "envelope" or "shell" of your home its outer walls, ceiling, windows, doors, and floors is often the most cost effective way to improve energy efficiency and comfort. ENERGY STAR estimates that can save up to 20% on heating and cooling costs (or up to 10% on their total annual energy bill) by sealing and insulating.
Insulation keeps your home warm in the winter and cool in the summer. There are several common types of insulation:
- Fiberglass in both batt and blown forms
- Rigid foam board
- Spray foam
- Reflective insulation (or radiant barrier) for saving energy in hot, sunny climates.
When correctly installed with air sealing, each type of insulation can deliver comfort and lower energy bills during the hottest and coldest times of the year.
Helping you understand Insulation and R-Value: insulation performance is measured by R-value its ability to resist heat flow. Higher R-values mean more insulating power. Different R-values are recommended for walls, attics, basements and crawlspaces, depending on your area of the country. Insulation works best when air is not moving through or around it. So it is very important to seal air leaks before installing insulation to ensure that you get the best performance from the insulation.
Sealing Air Leaks
Many air leaks and drafts are easy to find because they are easy to feel like those around windows and doors. But holes hidden in attics, basements, and crawlspaces are usually bigger problems. Sealing these leaks with caulk, spray foam, or weather stripping will have a great impact on improving your comfort and reducing utility bills.
