Overview

3mm Cork Underlayment – (Density 220 kg/m3) 300SF/box

Forna cork underlayment placed under the floors reflect heat of our body, thus offering a more comfortable feel and protecting the natural warmth of your feet.

As the thinnest in terms of thickness, our 3mm cork underlayment is presented in a raw corkboard pre-cut sheet format, perfect to be laid beneath your favorite laminate floors. Safe and comfortable. You will walk with ease and relax in comfort and tranquility. These sheets come in a 2ft x 3ft (24” x 36”) size and are packed 50 sheets per box, or can cover a 300 sq feet area. Made of 100% agglomerated cork that incorporates only water-based adhesive or binders during the manufacturing process, our underlayment is toxin free and recyclable. Buy knowing you’ve decided upon a green product that was harvested and processed to leave minimal impact upon the earth.

Our underlayment is a cost effective answer for reducing airborne and impact noise problems. Cork offers a higher level of sound reduction versus most standard foam underlayment. Unlike synthetics, cork is a natural material that—due to its unique 40 million cells per cubic centimeter honeycomb structure and the generation of Suberin—is naturally resistant to the growth of microbial organisms such as mold and mildew and will expand and contract with your floor. Forna underlayment can also be successfully used under wood, hardwoods, engineered hardwood, cork flooring, and bamboo.

Cork underlayment is formaldehyde free and will act as a thermal barrier, not only insulating your feet from the cold below, but also working to maintain the ambient temperature of a room for longer periods. Cork, with its elastic nature, gives when you step upon it, providing a comfortable cushion for your feet to rest upon.

As you can see, the natural properties of cork have demonstrated its formidable abilities and beneficial qualities. Add our cork underlayment to your home and witness this for yourself.

Cork is one of the most sustainable wood materials found in nature as only the outer bark is harvested from the cork oak tree to provide the material used for agglomerated cork. Each tree is left intact to regenerate its bark, thus a single tree capable of living up to two hundred years can reap a yield once every decade. Combined with the natural properties found in cork this makes it a better material for building in residential and commercial sites.

Synthetic Foam

Wood, Laminate, carpet and ceramic floors absorb out body heat, thus the floors have a colder feel. Classic synthetic foams do not provide thermal insulation.

Product buying questions

What is 3mm cork underlayment best for?

3mm cork underlayment is an acoustic and thermal underlay for flooring projects where low-profile acoustic layer needs, finished height limits, laminate, vinyl, engineered hardwood, tile, and light sound-control projects matter under hardwood, laminate, vinyl, tile, or cork floors.

Should I choose 3mm cork underlayment for sound control?

Cork underlayment can help with impact sound and thermal comfort, but the right thickness depends on assembly, finished floor height, subfloor, building requirements, and the flooring manufacturer instructions.

Can 3mm cork underlayment go under hardwood, laminate, vinyl, tile, or cork?

Often yes, when the flooring manufacturer allows an underlay layer and the substrate, adhesive or floating-floor system, moisture limits, and finished height are confirmed before installation.

Should I order a 3mm cork underlayment sample first?

iCorkfloor recommends samples so buyers can compare thickness, density, finished height, feel, and project fit before ordering full underlayment boxes.
