Super Warm!!
(This review was collected as part of a promotion.) This subfloor has already saved me money!! Installation was simple, no tools other than a utility knife to cut it was needed and it went down perfect. Immediately after placement I noticed a huge difference in temperature and I hadn't even installed the laminate over top yet. I would recommend this subfloor to anyone. I wish I had known about it sooner as I had already used a more substandard product in other parts of my home and the difference is like night and Day. It absolutely worth a few dollars more for much more warmth and was of use.

    Great warmth
    (This review was collected as part of a promotion.) I installed this product in my basement bathroom, directly over the concrete floor. Previously I had vinyl laminate directly on the concrete and the floor was quite cold, after I relayed it on top of the dricore subfloor, the temperature change was quite noticable. I did have some issues during the install, being a foam board, it cuts to size very easily, however the tongue and groove fits very tight and I broke the tongue and the first board I went to install. After that I was very careful and had no more issues.

      Well designed system
      (This review was collected as part of a promotion.) Laid the dricore on my basement floor. Very easy to install and the panel sizes are easy to work with. The pack of 10(80 sq ft) will fit in a car no problem. I am very impressed with the compressive strength of this foam. Perfect product to use if your basement has minor water seeping issues. The only problem I see is you will loose some height to your first stair tread if used in a retrofit situation.

        Dricore subfloor provides quick, easy cushioning
        The Dricore Insul-Armor is tough to be able to stand-up to the weight put atop your floor, yet still provides comfort underfoot. Laying out this sub-floor is so easy, thanks to the tongue and groove feature on the edge of each 4 foot and 2 ft sides. The panels don't even have to be glued down, and are easily cut to fit using a utility knife. It feels like styrofoam that has been super-engineered to be dense without air pockets and sealed so that it doesn't flake or chip apart unless it has banged into something. I stood on one foot and put nearly 175+ pounds of weight on it and it did creak, but did not crack or break. With tile it would help distribute the weight of your foot and you'd have even more distributed weight over the surface. You can see that the panels are a bit forgiving as ramping up over a oval mat was possible. One could easily cut the edge of the final tile to ensure a bit of adjustment, if needed. This seems so much easier than using floor leveler! If you're building new, note that you'll want to allow for that 1" under the framing. You'll have that floor finished in no time, and enjoying the warmth underfoot thanks to its insulated R value rating of 4.1. Find the instructions online at Home Depot's product page.
        Easy to install
        (This review was collected as part of a promotion.) Extremely easy to install and cuts with an exacto knife. 1” thick panels simply slot together and there’s 10 in a box. 80 square feet in total. I laid this down in a 100 sqft shed on top of the concrete pad. I just had to purchase an additional 20 sq ft to finish the installation, I laid ply overtop because I’m installing heated flooring cables but it’s so rigid you could lay Vinyl, laminate etc straight overtop with no problems.

          A standup product!
          (This review was collected as part of a promotion.) This product you can't go wrong with! It keeps your room warmer, softens the noise, keeps your floors safe from water damage, and makes your floors nicer to walk on. It's made of an inorganic foam to resisit mold, mildews and water damage. It clicks together with a tongue and groove system, making it easy for anyone to install. Each tile has dimples in the bottom as well, to allow airflow and resist water damage. The box it comes in is small enough to pack in an SUV easily as well. It's a pack of 10 in a box. I love this product. The price is right to save your floors.

            good product
            DRICORE 1 in. x 2 ft. x 4 ft. Premium Subfloor Specialty Panel (10-Pack) I’m pleasantly surprised with quality of product it comes in sheets and it is so much less headache than rolls. I really loved the sturdiness of the boards; floor will feel very stable it is rated to 3650lb per square feet and it does have R-value of 4.1. I like that it have those small bumps on the bottom so that concrete can have small ventilation. We haven’t installed yet, still waiting on the floor. This material is easy to install. No tape required to hold in place all thou I would suggest it if installed on concrete. It is Easy to cut with utility knife and does not crumble. Works well for sound dampening. I’m planning to use it under my engendered hardwood floor in my basement.

            No Organics Yes Please
            Very warm for a basement. We play soccer on it and it’s seems to hold up great with vinyl on top. It comforts me to know that there is know organics on my floor that is concrete and known to generate moisture.
