wrong thickness!
This is a review on the service and not the material. I ordered online 5 of the 2” foam boards and had to cut them in half so they would fit in the area i have to store them in until i can get them installed. After i had cut all but one of the boards i noticed some were a little thinner than others. Well you guessed it, i received 2 boards at 1.5” thickness and 3 at 2” thickness thst i had ordered. The 2 are going to be returned! And i don’t care if i have already cut one in half. I need the material I purchased and paid for!

    Worked great in our basement
    We are finishing the basement in our 1940 home. We used this product up against the concrete block walls and framed our 2x4 walls in front of it. We will be adding unfaced batt insulation in the walls and then covering the studs with a poly vapor barrier and then drywalling. The R-Tech EPS foam board is messy, but nothing the shopvac cannot make quick work of. We used a a drywall tee to mark our measurements, scored the facing with a utility knife and then a hand saw to cut it.

      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 was back and forth on what to use for skirting for my RV; the 1.5” or this 2” but ultimately decided “Go big or go home” and am glad I did. I used 1” last year and the difference is night and day. Not to mention, it looks better, too. It was easier to cut—we just used a little hacksaw from our camping gear. And combined with 3” metal tape, this project inspired other RV owners near us to upgrade to the 2” as well. It’s worth the extra money and you can see immediately it’ll just last longer anyway. Completely happy with this purchase and Home Depot delivered it in a box truck so we didn’t have to deal with the wind on the 30 mile highway drive back to base camp. Zero complaints.
