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.
- 可以倒,开始在一个角落里与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 usingLoctite Tite Foam Window & Doorbecause it remains flexible when cured and its low-pressure formula won’t overexpand and bow or flex the window frame.
