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.

Great even for abnormal use
My intention was for my concrete porch floor but was told the door jams wouldn't accommodate this and floor on top. So we looked at the basement and that wasn't worthy (100+ year old home). Leaving only the garage I decided to create pads for motorcycles. The project was easy and when I stepped on the Dricore how I wished it had worked in the porch! It would have definitely insulated the cold hard concrete. The panels went together easy and a level floor is a must.

Great idea for subflooring
I ordered this because we have a day basement which we want to replace he vinyl flooring in. I choose this for the moisture barrier attributes and its insulation properties. Thankfully, we have next to no moisture issues in the basement otherwise I would be concerned that these panels might trap it and create a mold problem. But because we’re only dealing with the most minor of moisture in the basement I figured I’d give it a try to make the flooring warmer and softer versus the concrete slab. It has definitely worked well for both of those things. The lvp we put down now feels more room temperature. As for the softness, the floor isn’t ‘soft’ but it’s not rock hard like the concrete was. It’s firm like any floor now. This stuff is surprisingly strong. I was pretty skeptical at first but it really does deliver what it claims. As far as installation, it is very easy to cut with a razor knife but you have to install it as you install your other flooring, not before, so it holds in place. The yo hue and groove are a bit tricky to get the to join, as some of the ends are bent and the tracks squeezed together but you just have to work it a bit. Then once your flooring is laid over top it’s stable and doesn’t slide around.

Pricy alternative to OSB
I have put down several hardwood floors and generally only used OSB and tar paper under them for a moisture barrier and to ensure a flat surface with the correct height. This is a nice alternative but seems to be focused on cement floors that may have some water intrusion and to provide an insulation layer. For the water intrusion feature, I'm concerned that this will mask the problem and may allow mold to grow under the panels. The panels are easily damaged and must be installed along with, and not before, the actual rigid flooring. It cannot be used with carpeting without yet another layer of something ridged over the top. Cutting is similar to drywall where you score the board and snap it, or slowly cut your way through with a utility knife. The tonged and groove makes for an easy floating installation in some cases, but in some installation examples they recommend nailing it down. For a specific type of installation, this may be the only alternative but comes with a price to match. I recommend spending a bit more and fixing any water intrusion issues. As an insulation option, I praise the company for providing this option but would not buy it myself for the purpose designed. I'm actually going to use this in a few projects for insulating outdoor pet enclosures where it is sandwiched between layers of wood. Other panels are much softer and these look like they may be easier to install and last over time.
Great Product
I was surprised by the light weight of the DRICORE 1 in. x 2 ft. x 4 ft. Premium Subfloor Specialty Panel. It was extremely easy to work with when trimming and edging. The insulation factor it provides it will help to eliminate the "cold floor" chill first thing in the mornings. This flooring also provided some level of sound proofing that is an added bonus with this sub-flooring.

Foam sub-floor panels that create a flimsy connection
I requested these DRICORE 1 in. x 2 ft. x 4 ft. Premium Subfloor Specialty Panel (10-Pack) from the Home Depot Seeds September campaign for a bathroom remodel I'm doing for an appliance install. While the idea sounded great initially, when I tried connecting two panels together I quick found that the panels don't even interlock as solidly as the engineered laminate wood flooring I am putting down. It is more of a slide together hold rather than an interlocking groove which I am not confident will prevent shifting when there is 500 pounds of stacked washer and dryer vibrating the floor below it.

Dricore Subfloor
Engineered foam subfloor panels; approximately 2' x 4' x 1' thick. R4 insulation value. Works well over concrete or rooms over unheated areas. The product is easy to transport as it is so lightweight yet remarkably sturdy underfoot. Effortlessly modified with razor knife. The product is not inexpensive however value is in convenience, moisture and mold resistant features, and comfort.

Great Solution for a Basement Floor
I have been working to fully insulate my unfinished basement to reduce humidity and to improve temperature -- so far I have been very happy using 2 inch XPS on the walls and notice a huge improvement in temperature and humidity control. I now am looking for a solution for the floor, but am not in favor of using the same XPS on the floor, as it requires two layers of OSB or plywood to ensure it is strong enough. This will result in an unacceptably thick 2 1/2 inch floor system, and I have only 7 1/2 feet to the ceiling joists right now. This system gives me a great solution for my hard surface floors, as the entire structure is only 1 inch, and the system lets you lay your hard floor directly on top. These are very easy to install and handle -- the foam is a LOT more dense than the XPS and does not crush even when kneeling on it (note you need the flooring on top to ensure that nothing pushes into it in the final install). Great solution! I'm seriously considering trying out the other products for my carpeting areas as well.
