Instructions

Step 1

Clean the windows

Once the windows are weatherized, it will be hard to clean them and enjoy the outside view. Thoroughly clean them before installing any weatherization products.

Step 2

Seal around the windows

Look for any cracks or gaps between the window and the window frame. Fill any cracks or gaps with caulking. Follow the manufacturers recommended application guidelines.

Step 3

Check the weatherstripping

Weatherstripping provides the seal between and around moving window parts. With time and use weatherstripping wears out. Look for cracking, peeling, and missing weatherstripping.

Weatherstripping can be specific to a particular application. Select the proper weatherstripping for the application and follow the manufacturers instructions.

Step 4

Install storm windows

Not everyone can afford new insulated windows. One option for insulating old windows are storm windows. There are many types of storms windows but all add additional R-value to windows.

Storm windows are made from a variety of materials and might be installed on the interior or exterior of the home. If you have storm windows, take them out of storage, check their condition, and repair if necessary before installing.

Install insulated curtains

Insulated curtains can significantly raise the R-value of your home windows and still allow the enjoyment of a scenic view during the day. Today there are many styles of insulating curtains and different degrees of R-value to choose from.
