Worked as designed. EPS is better than XPS in long term studies and about half the price. No issues with walking all over it while placing PEX and rebar.

Easy to work with and lightweight. Using it in my cargo vehicle I'm building out as an RV. An electric 'hot knife' makes it cut like butter and cuts can be very precise for a tight fit (though it smells like burning plastic when it's being melted by the hot knife).

Great for DIY craft projects. I wanted huge 42 inch round and 52 * 32 inch oval foam boards for a craft project. I found this insulation board in Home Depot store at Monterey hwy SanJose but was not sure how to cut it in the required shapes, also it was not possible to carry the huge foam board in the car if it was not cut into manageable sizes in store. Konstantine, a store associate there, was very kind to help me cut the foam board in perfect oval and round shapes. Many Thanks to him and other store associates who were very helpful.

It is a little messy to work with, but I felt it was worth it in the long run. I measured and cut it with a small porcelain knife. I felt a saw would make a bigger mess, and I was just using it for a SHE SHED, lol. I only needed a broom for clean up, and it seems to be keeping the temp reasonable even though it is winter.

I buy this to put under my swimming pool. It prevents debris under the liner from cutting it and is is very comfortable to walk on.

I used this styrofoam to insulate the windows in a room that is rarely used but brings a lot of heat into the house. It worked very well and I am sure it will reduce my energy bill.
