Tips For Weather Stripping Casement Windows

| 10 April 2017

Part of casement window installation is getting the weather stripping right. This is one of the most important steps in making sure you have installed your windows properly because weather stripping is going to protect both your windows and the inside of your home. If you are thinking about undertaking your own weather stripping project and are uncertain about whether you are going to get everything just right, below are some tips for weather stripping casement windows.

How To Weather Strip Casement Windows


Before you begin, you are going to want to make sure that the windows are clean so that you are not sealing in any dirt and grime. You should give the bottom of the sash a thorough clean with soap and water and let it dry before starting the weather stripping process.

Getting the foam right

The next step, once the sash has completely dried (this is important), is to cut the weather stripping foam to length. You are going to want to take careful measurements to do this because getting them just right is key to casement window installation that looks professionally done.

Installing the adhesive

After you have cleaned and dried the windows, and the foam has been cut to the exact length of the weather stripping, the next part of the casement window installation is peeling back the foam and placing the adhesive against the bottom of the foam so that it forms a tight bond with the stripping. You are then going to want to clean the jamb with soap and water.

V channel

The next step is to cut the V channel one inch longer than the sash height, peel it back and work it into the sash stiles and the jamb. You should press the V channel firmly into the jam and then hammer nails into the weather stripping through the jamb so that it is held in place. Test the sash after to ensure it is not catching on any nails. Give the bottom of the sash a clean with soap and water and allow it to dry.

Cutting the V channel

Cut a piece of V channel so that it is the same width of the sash and, with the sash raised about 3 to 4 inches, peel the back from the channel and attach it securely to the back part of the sash, including the top. The V needs to be open-facing so that your weather stripping will compress while the window is closed.

Casement window installation, particularly the weather stripping, can be a bit of a learning process, but, if you keep the above tips in mind, you should be able to install your weather stripping without anyone being able to tell that it wasn’t done by a professional.
