Insualting behind Window Trim

This is the same video for foaming around window trim. However, I noticed that my editing program cut off 15 seconds on videos i tried to speed up to 105%. This helps shorten video length. Also there were parts around the base of the window where the audio was sped up and shouldn't have been.

This video will show you how to insulate behind drafty window trim by removing the trim and old insulation and using canned foam to stop air flow as well as add some R value. Then just pop the trim back up and add some caulking and you're good to go.

For any foam projects be sure you are using the correct foam. For window and door projects look for low expansion foam.

Be sure to remove as much insulation around the top and sides of windows for the base you will typically be filling a small area around there the window is shimmed.

In this case the window had a large gap between the rough opening and we were able to foam that.
