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: Do I need to air seal my attic before installing insulation?

• <div><p>Air sealing isn't necessary for attic insulation, but it's incredibly helpful since it can help you identify and patch any existing air leaks. Failing to find these leaks before adding insulation can render your insulation less effective, leading to higher energy bills and potentially costly repairs down the line. </p></div>

Q: Do installations include soundproofing options?

• <div><p>Yes, professionals can add extra insulation or backing for enhanced sound control.</p></div>

Q: How long does duct insulation last and when should it be replaced?

• <div><p>Air duct insulation typically lasts for 10 to 15 years or even longer, depending on the material and maintenance. It's important to conduct periodic inspections to check for signs of deterioration, such as water damage, tears, or general wear. If you find any of these issues, it may be time for repairs or a full replacement. You might also consider upgrading your insulation even if it's in good shape to improve your home's energy efficiency and enhance your HVAC system's performance with newer, more effective materials.</p></div>
