Sealing and Insulation

Paying attention to the details – windows, doors, floors - can add up to big energy savings.

Sealing

Seal any cracks, gaps, holes or other similar areas where there may be a draft.

Caulk wherever two different materials or parts of the house meet, like doors, windows, electrical plates and utility ports. Caulk is available in a variety of forms. Select the one best-suited for the part of the house you are improving.

Use weather stripping around areas where frequent movement occurs, like doors and windows. You have some choices to make when it comes to weather-stripping. You may need spring metal, rolled vinyl or adhesive backed weather-stripping, depending on the type of windows and doors you have. Weather-stripping can be purchased by the foot or in kit form, and there is a special kind for double doors, which often are hung with a substantial gap where they meet, so the doors can swing freely.

Check the weather stripping around your garage door and replace if needed.

Consider a “door sweep” for the bottom of doors, especially doors leading to the basement and outside.

Insulation

Make sure every part of your house is insulated. Most older homes don’t have enough insulation, but it can be added to any home. Insulating an attic is usually a “do-it-yourself” project that reaps big energy rewards.

Add insulation to your attic. Increasing attic insulation can save up to 30 percent on your heating and cooling costs. 

Make sure the insulation in your attic is 10-12 inches deep to help keep your home comfortable, and if you have a crawl space or basement, use an insulation wrap to help blanket your living areas.

Check out the EPA’s Energy Star® DIY guide to learn about R-Values – the measure of how well each type of insulation conducts heat – and see if updating your insulation might benefit your bottom line.

Reconsider glass doors. These doors are poor insulators and will transfer heat quickly.

Use storm doors for added insulation if your primary door is poorly insulated. 

Close your curtains and shades and add awnings over your windows to block direct sunlight and keep your home cool.

Purchase double-pane windows that offer added insulation. Look for ENERGY STAR® windows, which meet minimum energy efficiency standards. 

Use carpets and rugs to help insulate your floors and contain heat. Thick, wool rugs are the best at keeping warmth in, but even thin rugs help with how the temperature feels around your home.

Strategically place carpet and rugs in high-traffic areas/rooms of the home. They will help keep bare feet warm.
