Q: Can you put insulation on top of ductwork?

• <div><p>Yes, you can install insulation over ductwork, and doing so can save you money.

Insulating HVAC ducts makes your system work more efficiently, saving you money on heating and cooling bills.</p></div>

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>
