Q: Is it worth it to remove old attic insulation?

• <div><p>The life span of insulation is between 20 and 100 years. At that time, existing insulation can fall victim to gravity, resulting in compression, which reduces its insulating protection or R-value. If you can't simply add more insulation over the existing material, removing the old to increase the effectiveness of the new can reduce your energy bills and make the project worth the time and money investment.</p></div>

Q: What is the safest insulation for basement walls?

• <div><p>Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don&rsquo;t have to worry as much about a fire breaking out as you would with spray foam insulation. </p></div>

Doorbell Installation FAQs, answered by experts

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation:

If the insulation is over 15 years old
If the insulation is wet or moldy
If it is vermiculite insulation
If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.

The life span of insulation is between 20 and 100 years. At that time, existing insulation can fall victim to gravity, resulting in compression, which reduces its insulating protection or R-value. If you can't simply add more insulation over the existing material, removing the old to increase the effectiveness of the new can reduce your energy bills and make the project worth the time and money investment.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation.

If you’re using faced insulation with paper, face the paper toward the inside of the room during the installation process.

A good way to remember this is that the paper should face the “warm side” as it’s the vapor barrier, meaning it should face toward where the heat will be coming from.

If you need to insulate behind finished walls, the best option will likely be to have an insulation professional install blown-in insulation. The installation requires small holes cut in your wall, after which the installer can blow loose-fill insulation into the void. After the installation, you’ll have minor drywall patching, which shouldn’t cost more than $100. Compared to ripping down the existing drywall, using a different type of insulation, and replacing and finishing the drywall, this should save you hundreds or even thousands, depending on the size of the room you’re insulating.
