Ratings & Reviews for GreenGuard R- 5 , 1-in x 2-ft x 2-ft Unfaced Foam Board Insulation

Expensive insulation.

Expensive but thick insulation. cut clean one way and ragged the other

first 1 inch of insulation saves the most energy

small size

Great surface tension for my Hobby.

As an hobbyist I like the texture I get from this product, there are many things that can be accomplished with this material.

It is what it says

It's a big square piece of insulating foam 😐. Not sure how exciting that is

Didn't get squashed

This product was specified with a higher compression strength a similar foam board at HD. I bought this to be a moisture and thermal break under my new 65 gal hybrid water heater. I was going to try to cut a circle, but simply cut an octagon with my miter saw.

Can be used for projects other than insulation

Perfect for my project

know what you want and what you're using it for

It's great insulation but I wish it came in a bigger size

Do not buy online, take time to sort for good ones

Product was horribly stored, haphazardly thrown on the floor. Had to go through at least 1/2 of them to find 3 good ones.

Good product

Liked the product. Was easy to cut.

3D printer vent

Works great, used it to replace my attic access panel. Cut a circle in it and vented my 3D printer into the attic.

It works well
