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. Properly suiting up helps you avoid several fiberglass issues, such as cuts from the tiny shards of glass and inhaling small bits of fiberglass.</p></div>

Q: How do I know if my insulation needs replacing?

• <div><p>One of the clearest signs that your insulation isn&rsquo;t working as well as it should be is a noticeable difference in temperature throughout your home. One room might feel icy while another is hot as Arizona&mdash;this indicates that some parts of your home are either retaining or losing heat more than others. Additionally, a sudden increase in your energy bills, evidence of pests or rodents, or evident water damage are other signals that warrant a thorough inspection of your insulation and potential replacement.</p></div>

Q: What happens if you don't install a vapor barrier?

• <div><p>While not every wall requires a vapor barrier, if you do need one and don&rsquo;t install it, moisture can get between the walls of your home. This can lead to water damage from mold growth or rot, and the excess moisture could also attract pests, including termites, cockroaches, or ants.</p></div>

Q: Should ductwork be wrapped in insulation?

• <div><p>Ductwork should be wrapped in insulation in certain locations. This includes unconditioned interior parts of the home, such as attics, crawl spaces, basement ceilings, and between floors. Duct joints should also be insulated since they're more likely to leak air than other parts of your system. Building codes in some areas also require ductwork to be insulated. </p></div>

Q: What is the best insulation for air ducts in the crawl space?

• <div><p>Mineral wool wraps are the most affordable and effective insulation for crawl space ducts. They are easy to cut, last for a long time, and healthier for humans. Meanwhile, fiberglass wraps are cheaper but more hazardous and difficult to handle. If you do choose to use a fiberglass wrap, make sure you are wearing long sleeves and wear proper protective gear.</p></div>
