While fiberglass insulation is usually cut with a utility knife, as demonstrated in our Cutting Insulation video, one of our viewers came up with a novel idea which worked great and gets the job done in a hurry. Here it is:
“We were insulating our bonus room with R-38 bats in the ceiling, and about two-thirds of the way through the job I wished out loud that I had a longer knife to cut the 12” thick bats. Then it occurred to me: MY ELECTRIC CARVING KNIFE!!!
“It’s incredible how easily it works and can even cut the kraft paper, though I usually use scissors for that.”
