Watch for a quick tutorial on how to air-seal with canned foam around a window.

Using low-pressure foam to air-seal around windows and doors is a great way to improve a home’s performance. Here’s how to do it:
- Using proper safety gear, shake the can for at least 30 seconds and firmly attach the applicator straw.
- With the can inverted, start in one corner with the straw inserted about halfway into the gap and gently pull the trigger to dispense foam. Work your way around the window. The goal is to create a continuous bead between the window frame and the rough opening while leaving a continuous gap at the exterior flange. On the interior, a second pass can fill the void for more insulation.
- Once cured, trim back any excess foam with a utility knife.
We’re using Loctite Tite Foam Window & Door because it remains flexible when cured and its low-pressure formula won’t overexpand and bow or flex the window frame.
