Rated 5 out of 5 by Used for birthday party decorations I bought 3 of these sheets for my sons first birthday party! It was a jungle/safari themed and I sent them out to my friends bf to paint some animals. He did a mural/background typed n I used it as a backdrop for the chocolate fountain table. The other two were giraffes that I put on bushes since the party was on our backyard. This year doing a Mickey Mouse themed n I'm going to buy some of these sheets!! March 19, 2013
Rated 5 out of 5 by Used for new application Used this to temporarily cover a hole in the ceiling while we wait for spring to do roof repairs. Board very light, easy to screw into studs, completely waterproof. Much easier to use than plywood or drywall and much sturdier than a plastic sheet! Also kept the room warm! March 11, 2014
Rated 5 out of 5 foam sheeting I love this stuff, it has a great color! I love pink, but seriously, this stuff is as soothing to place against a wall as it is too look at! It seals perfectly, last forever, and is so cleanto work with. We love using this for all our insulating work, and prefer it for the price to the other options. We have a notable difference in the heating and cooling benifits it makes, and our lives are richer because of the clean and effective insulating factor it has. August 23, 2010
Rated 5 out of 5 by can be used in so many ways Cover boards with your choice of damask fabric and hang on wall for a custom art piece. So cool . June 20, 2013
