WIDGETCO® 12mm (1/2") Cork Underlayment Sheets Sheets are made from natural cork. Cork Underlayment Sheets is a natural sound insulator and will work with both wood floors and tiles to help reduce walking noise and act as a thermal insulator. Cork natural properties resist mold and mildew. Each sheet is 6 sq. ft. (12mm x 2' x 3'). Each box contains 8 sheets or 48 sq. ft. Cork Underlayment Sheets install quickly and easily and do not curl up as can occur on underlayment rolls.



Used for bulletin board

The 1/2" cork worked very well for a wall bulletin board and push pins have ample room to work. We adhered the cork to the wall with an adhesive and it worked well.

Great Product

Shipping was quick and easy, even arrived before my underlayment, which I ordered days prior to the cork. The cork itself is good quality, not the crumbly mess in cheap cork boards or bottle stoppers. It has a great underfoot feel. I DEFINITELY recommend the 12 mm cork over 6.

All boxes were intact when they arrived. All cork pieces were intact and of good quality. All in all I had a great experience with this company and would shop here again.

12mm (1/2) cork underlayment

A beautiful product, even it will not be seen in the final installation, it will provide the assurance that our condo will be will be better insulated and less likely to transmit sound downward. The top will be porcelain tile which already feels good underfoot with the underlayment of the 1/2 cork. Thanks!

[From WIDGETCO: That "underfoot" feeling is often overlooked, so thank you for mentioning it. Less shock and a more natural feel. The difference is impressive.]

Carolyn W., Los Angeles, CA - 4/6/2016

Best price I found on the net

I'm using it for a table top for a slot car and train track.

Np, Wisconsin - 2/16/2016

1/2 Cork

Fast delivery, good service. My use of it is for decorative purposes: framed as pinning boards for small art works. The cork's texture itself is beautiful. Easy to cut. Thank you!

[Reply from WIDGETCO: Thank you for the compliment...we agree it's beautiful material and sad so much of it gets hidden below flooring.]

Model Builder

My order for one pkg. of 1/2" cork arrived very speedily. While the package was a bit banged up the cork was not. My unusual application is that of a "building board" for model airplanes where the requirement is for the "board" to take and hold straight pins well. While I not yet actually built a model this way preliminary "pinning tests" strongly suggest this product will work out well. I have 'way more material than I need so I will be sharing it with some model building friends. It will take a while but I expect a collective evaluation for this application.

Cork Underlayment

Excellent quality and price. Cork is dense and smooth. Fast shipping. I have ordered twice from this company and would definitely recommend them.

Tom G, Rotterdam Junction, NY - 10/29/2015

True 1/2 " Cork Underlayment

Excellent product and fast shipping. Installer commented that product was far superior and was much drier then cork coming out of China. A little more expensive what you get out of China, but you are assured that you do not have any formaldehyde! The product is from Portugal, where 80% of cork is produced. Not worth to risk health for a cheaper product! Buy this one, it is the best.

Value and Quality

Researched and happy I came here after looking at local places and saying, really, that much for so little? This product has 7 sheets 2' x 3' per box, and it is smooth great quality cork. I am using it to cover a work table for stained glass. Could not be happier with the product, the ordering process, and how quickly it was delivered. Great company and great product.

Dave S., Aurora, CO - 9/28/2015


Smooth as silk!

1/2 " Cork Underlayment

The order arrived quickly and the cork tiles were in great shape. I am very pleased with the company and the product and the price.

Home owner

Product as described. Delivery as listed on time. Second order and will order again if need be.

Mike K, Conneticut - 4/1/2015

Nice and thick

This is the thickest sheet product I could find. I'm using it to make a sound-dampening box for my shop vac, not on the floor. Arrived in a flash.

Terrie N, Santa Rosa, CA - 3/23/2015

Delivered as Promised

Cork is high quality and was delivered quick! Great company to order from, package arrived quicker than expected. Highly recommend. Used the cork as an underlayment for heated floors. Works great!

Ken M., Utah - 3/17/2015

1/2" cork underlayment

If you are looking for something you can use as corkboard, this is amazing stuff. I ran it around my secretary's space in the lobby and it looks phenomenal! Lots of positive comments on how contemporary the effect is. Priced very reasonably. Fast shipping, too. Even during the most recent ice storms.

Lynne C., Tennessee - 3/8/2015

Exactly what is pictures. Thick, beefy cork squares

Using them on a wall for sound proofing and proofing prints. Worked like it was made for it.

Scott V, Tennessee - 2/27/2015

Great Product

Purchased these boards to cover a wall in my office - worked beautifully. Product shipped the same day that I ordered and had it within a couple of days. Excellent service and product - well done WIDGETCO!

Andrew V., Cincinnati, OH - 1/15/2015

Just what I needed

I bought these to make a message board for my office. I needed a square foot size cork and this was great thickness and quality for what I needed. It was easy to cut to size and the price beats any craft or local general store by far.

Jennifer B, Wimauma, FL - 12/11/2014

Order out of stock

We ordered the 1/2 cork and it was out of stock. We are in our second week of waiting for our order to be delivered.

[Reply from WIDGETCO: Very sorry, we pride ourselves on keeping all our products in stock, but occasionally we fail. We will get you an ETA for your order.]

Charles K., Menlo Park, CA - 10/24/2014

1/2" Cork Underlayment

Have not used the cork yet, but on inspecting the product it is going to make my laminated flooring so much easier to install. Quick shipment is a plus. Your product is excellent and I am glad I found it on the internet.

Harry O., Iron Mountain, MI - 9/9/2014

1/2" Cork Undrelayment

Item arrived quickly. These sheets are square and dense. Would make excellent soundproofing. I was able to attach to wall using inexpensive general purpose vinyl floor covering water-based glue. Applied layer to wall and to cork and put in place after 15 min wait time. Used 1.5" ring-shank nails to secure edges and will remove when glue dries. Good product.

David N, Euless, TX - 8/25/2014

1/2" Cork Underlayment

I am very impressed. The cork arrived much faster than I expected, in perfect shape, and at a price that no one else I looked at could even come close to. I will be using WIDGETCO again. Thanks!!

Greg N, Amery, WI - 4/17/2014

1/2 inch Cork Underlayment

I bought these cork sheets to build model airplane wings on. I can pin the parts down to the board before gluing. The order arrived promptly and is exactly what I needed. Obviously, WidgetCo is very customer service oriented. A pleasure to do business with.

Bob T, San Leandro, CA - 3/9/2014

1/2 inch thick cork board

8 sheets in the package and all 8 in perfect condition. Plan to use them for our community bulletin boards. I will probably be ordering another box of 8.

Tom S., Ft. Myers, FL - 2/22/2014

Tile underlayment

I needed 350 sq feet of cork to insulate my concrete floors before I tiled. The panels arrived within five days in perfect condition. They are all of consistently high quality. I am very pleased. I am a general contractor.

Willy B, Petaluma, CA - 1/27/2014

Huge cork wall

I used these to construct a large cork wall in my printmaking studio. Perfect! Love them.

Ape B., Cleveland, OH - 1/7/2014

Wall bulletin

Used this on the wall. Drilled screws into each corner and using this as a community bulleting. Looks great and seems to be of good quality.

Nancy, Atlanta, GA - 4/13/2013

Table Pads anyone?

VERY pleased with product and extremely fast and FREE delivery. Hubby cut to size of our new Amish table and attached to masonite to make a VERY protective cover for our new table top.....VERY VERY HAPPY ME NOW! THANKS!!!
