Should you remove old insulation before adding new insulation?

• <div><p>You do not always need to remove old insulation before adding new.

Should wall insulation be faced or unfaced?

• <div><p>Unfaced wall insulation is easier to cut and install, making it the better choice for a DIY project. It’s also more affordable.

Q: Should you wear a mask when cutting insulation?

• <div><p>For your safety, you should always wear a mask when cutting batts of fiberglass insulation. We also recommend wearing eye protection, safety gloves, and long sleeves to protect your skin.

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>

Q: Is installing crawl space insulation worth it?
