General Description
Cork Underlayment – 7/32" thick – 49' 2-9/16" long
The pure cork underlayment is 7/32" mm in thickness and is 49' 2-9/16" long. The color of the cork sheets is beige and the material is cork.
Function
The cork insulation easy to install underneath various kinds of flooring material for reduction of sound transmission. The underlayment must be installed before the flooring or carpeting is put down and cannot be put in after the fact. The underlayment provides thermal insulation, and it is durable and hypoallergenic. The material is non-toxic to make it environmentally friendly, waterproof and moisture-proof.
Applications
The cork insulation is ideal for noise reduction for flooring surfaces in residential, commercial or industrial applications. It is especially useful in places where there is a lot of noise that needs to be dampened for noise pollution reduction, a vapor barrier, and overall comfort. It can be used under many floor types, depending on your installation needs. Multiple lengths and thicknesses are available for this reason, so you can find the appropriate match for your installation job.

Hi can the Cork underlay be used as a corkboard? Would you use tbe 5mm? Kind Regards Habib.
Yes, the cork underlay can be used as a corkboard. The 5mm should be suitable for your purposes, and we have it in stock.
I am planning on laying vinyl planks over cork underlay to assist with foot traffic noise upstairs. How much noise (DB) would D1173459 reduce compared to a rubber cork mix? Just trying to decide if the extra expense is worth it. Thank you.
D1173459 and our other cork underlayments will reduce about 30dB of noise.
What is the best method of fixing the cork, if it was applied to a wall?
You can simply cut out the broken part of the cork, then cut out the same shape from the spare cork with same thickness. Put it back in to fill the hole.
Please detail application method. ie Does it need to be glued down? If so should it be across the whole product or just on the edges? If one is using vinyl boards as the flooring should they be glued to the cork? Is the pure cork underlay better than the cork/rubber mix in terms of noise reduction? What are the pros and cons of these two? Can one use a cork underlay as well as a cork/rubber underlay (one on top of other)?
Hello Felicity, thank you for your questions. Surface Preparation - Surfaces must be clean, dry and smooth, free of voids, loose materials, oil, grease, sealers and all other surface contaminants. Surface areas requiring patching or leveling should be repaired with cement materials. Creating an Isolation Barrier - Unroll cork and cut sections approximately 2” wide off roll. Adhere this 2” isolation barrier around perimeter of the entire floor with any of the entire products. Never mechanically flatten the isolation barrier with screws, nails or staples. This will severely diminish acoustical values of the barrier. Installing the Sound Control Underlayment - Unroll cork and cut to desired length. Lay cork loosely over area to be installed. Both ends of the roll must curl down towards the subfloor. If the ends curl up, flip material over. Butt cork directly against the isolation barrier already installed. Pull the loose laid material back at least half the length of the roll. We strongly suggest across whole product and you can glue the cork on vinyl boards. Cork/Rubber Mix has better noise reduction level than Pure Cork material. Meanwhile, cork has soft, cushiony surface, hypoallergenic, antimicrobial properties and environmentally-friendly; but it's susceptible to damage and sunlight can cause cork to fade. On the other hand, rubber can withstand heavy foot traffic, easy maintenance and more durable; the cons is it's slippery when wet and expensive.
what are the ic and stc ratings on concrete
Hello Rhonda, thanks for your question. Our suppliers use different methods to measure a product's soundproofing ability. This underlayment blocks about 28 dB of noise. If you have any other questions or concerns please do not hesitate to contact us.
Do you have information on the thermal insulation properties of the cork and cork/rubber underlayment?
Hi Ian, thank you for your question. The weather resistance of an underlayment is -25 to 80 degrees Celsius or -13 to 176 degrees Fahrenheit. If you have any other questions or concerns please do not hesitate to contact us.
