The Importance Of Weatherizing Your Home For Energy Savings

May 1st 2015 at 3:19 PM

Most homes, even fairly new ones, have many places where air can leak out of the interior. Older homes in particular may be drafty and open to the elements. This can dramatically reduce the efficiency of your heating and cooling system and end up costing you a lot of money.


To save money on your energy bills and help your HVAC system run more efficiently, it is important to weatherize your home. This involves going around and sealing up any areas where air can leak out of the house. By doing so, you can make sure that you are not wasting a lot of energy. This will also make your home more comfortable throughout the year.

Start by checking inside your home for gaps between the floors and the exterior walls. If you find any, use caulk to seal them. Inspect your windows for gaps and seal these with caulk as well. You can usually tell where a draft is getting in near a window.

If your windows are double-hung, out weatherstrips on the tracks as well as on the upper sash's bottom. Any broken or cracked panes need to be replaced right away, and putty can be used to repair loose panes. All moving parts need to have caulk in place to avoid drafts.

Having exterior storm windows installed can really cut down on drafts as well, especially for single-pane windows. You can also use plastic to provide additional insulation inside your home. These sheets of film will help cut down on the amount of air that can escape around your windows.

Doors also can allow a lot of air to escape from the inside of your home. While a certain amount of loss is inevitable as people go in and out, you want to take steps to reduce the amount that can escape when the door is closed. Weatherstripping should be installed around any exterior doors, including near the door jamb.

A lot of air may be escaping from your attic, especially if you have an older home. In homes built before the 1950s, exterior wall cavities were often left open to the air. These should be insulated and sealed up to block the flow of air. If there are any openings on the attic floor, these also need to be sealed to keep air from leaking up into the attic.

The heating ducts that run into or through the attic also need to be sealed and insulated. Metal-backed tape can be used to seal seams and joint, and the duct should then be wrapped with R-6 insulation. Any gaps around other pipes or vents should be sealed with caulk.

Any openings in the exterior walls of the house can allow air to escape. Check for these where pipes or cables enter the home, and seal any gaps with caulk or putty.

By weatherizing your home, you can make sure that warm or cool air stays inside. This way, you can lower your energy bills and stay comfortable all year long.
