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>

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.

I would highly recommend Greg Hill. He’s a great guy and he knows what he’s doing. We appreciate all the work he did on our new church project. He took a 112 year old building and turned it into a modern day sanctuary, kids church and offices. We are totally loving it.
