Take the Heat Off: Step-by-Step Guide to Installing Closed-Cell Foam in Your Attic

Installing closed-cell foam in an attic can be a great way to help protect your home against the elements. This type of foam is applied by spraying liquid foam into attics, walls, and around other areas where insulation may be needed. The liquid then dries and forms a hard foam that is resistant to moisture and insects. That being said, closed-cell foam is slightly less resistant to moisture than open-cell foam and tends to be significantly more expensive. However, with the right equipment, you should be able to do this job yourself.

Before beginning installation, you’ll need to clear any items out of the attic so you have enough space to work. You’ll also want to check the attic and walls for any holes or gaps that need to be addressed before the installation. To seal off any holes or gaps, simply add some caulk, glue, or nail boards over the openings so the foam won’t escape. This will help to reduce the amount of foam needed for the job and make your attic more energy efficient.

Next, you will need to obtain a spraying suit. This suit will cover you from your feet to your head and even includes a hood and a face mask. Be sure to zip it up all the way and seal the mask before you begin. Once the suit is on, you will be ready to start the installation.

Now, you can move the spray machine into the attic and plug it into a nearby outlet. Carefully maneuver the nozzle around the side of the attic walls and begin to spray the foam into the openings. It’s important not to overfill these areas up to bursting as the foam will expand when it dries. Spraying in an even layer of foam is the most effective way to insulate your home.

When you are finished spraying the foam into the spaces, allow it some time to dry before you remove your spraying suit. Once the suit and machine have been returned, your insulation job is complete. You should now be able to enjoy a warm, insulated home for years to come.

Installing closed-cell foam in an attic can be a labor-intensive and may require some special equipment. However, if you follow the instructions outlined above, you can do the job yourself with relative ease. Just be sure to take proper safety precautions, such as wearing a spraying suit and closing up any holes or gaps as you go. Doing this should help you create a more energy efficient home, allowing it to remain toasty warm even during the coldest months of the year.
