How do I cut rigid form insulation?

How do I cut rigid form insulation?
Asked by: thomas
A hot wire cutter is going to give the quickest, cleanest cut. A knife or saw will work as well but they are a bit trickier and messier.

Can you paint over this insulation?

Can you paint over this insulation?
Asked by: MsPainter
This foam board has aluminum foil on one side and a thin white plastic skin on the other. Can't paint either of them. HOWEVER, if you are able to peel either the aluminum or the plastic off, you COULD paint it, but better use a LATEX paint!! Oil based paints will eat this stuff like a hog in a melon patch. It will just dissolve with anything besides LATEX!!! Don't know why you'd want to paint it, but it can be done, even though it won't win any beauty awards.

1-1/2 in. x 4 ft. x 8 ft. R-5.78 Rigid Foam Insulation is rated 4.5 out of 5 by 22.
Rated 5 out of 5 by from Use a electric carving knife to cut This product worked great. The electric carving knife I used to cut the panels is the way to go. My garage and the rooms above it are noticably cooler. Less than $80 to do my double garage.

Rated 5 out of 5 by from Great stuff...fun to work with I insulated my 6' X 12' enclosed cargo trailer every inch from top to bottom with this stuff, and was very impressed after I mounted a 5,000 BTU AC on the back door. It's like a walk-in cold storage freezer. lol The air condition unit now runs for approximately two minutes or less at every fifteen minute interval as opposed to nearly continuous 24/7. Sound proofing characteristics of this product are what I consider to be moderate to very good as well. As each panel went up I could notice the difference as it gradually eliminated an 'echo' throughout the trailer. Could not be happier. Excellent value per sheet. Fun to work with. I used a six inch 'utility scraper' razor blade to cut it up. :)

Rated 5 out of 5 by from Retch 1.5 inch perfect for garage doors This 1.5 inch polystyrene insulation is a perfect fit for newer non insulated metal garage doors. Way cheaper than the kits and looks great too. Just cut it with a razor knife and you're good to go.
