Frequently Asked Questions
Why use cork?
It's eco-friendly, easy to maintain, provides thermal and acoustic insulation, it's comfortable to walk on, provides a unique design, and is extremely durable.
Why is cork flooring and cork wall tiles such an environmentally conscious choice?
Cork is one of the most renewable sources for flooring. Harvesting the cork oak for its bark is strictly regulated, limiting such harvesting into nine-year cycles. The individual cork oaks must be at least 25 years old before they are harvested and when they are, the health of those cork oaks must be ensured. The cork oak is harvested by hand, and remains unaffected by the harvesting process. The bark of the cork oak grows back, leaving the cork oak as healthy as ever.
Is cork flooring a new idea?
Cork flooring was first used popularly at the end of the 19th century. By the early 20th century, Frank Lloyd Wright was incorporating cork flooring in some of the public buildings he designed. Many of these buildings still feature these original cork floors.
Where can I use cork flooring?
Cork flooring can be used in any type of room in your house or business. Kitchens are one of the most common places where cork flooring can be found since it’s comfortable to stand on and easy to clean.
Where can I use cork wall tiles / cork bulletin boards?
Cork wall tiles can be used in any type of room in your house or business. Cork wall tiles are suitable for walls, ceilings, bulletin boards, backsplash, and inlays in furniture. Cork wall tiles are not only decorative they are also self healing from pin board use.
How long does cork flooring last?
When cork flooring is properly maintained it can out last the owner. This requires proper maintenance and cleaning of your cork floor. Stones, gravel and dirt can cause wear and tear if not removed from the surface for long periods of time. Don’t use any strong cleaners on the floor either; this can actually weaken the properties of the cork.
Is cork flooring a good option for pets?

habits, activities, and potentially destructive actions of your pet better than
Cork floors are coated with a finish that that protect it from cats and dogs running on the floor.
Will cork flooring resist high heels and heavy furniture?
Cork itself is a very dense and compact product and is designed to withstand commercial traffic. Cork has a lot of memory due to the air cells and recovers well from most objects. Like any floor, cork can be punctured by sharp objects and damaged by furniture feet. It is recommended that furniture with sharp or damaged legs have protective pads placed on them.
Is cork flooring water resistant?
The easy answer to this question is to think of a common product, the wine cork stopper. The reason that wine producers use cork is that it is an excellent repellent of moisture. A natural substance found in cork called suberin, a waxy material that is a key component in the compositions of the cork cells, is responsible for the moisture-resistant nature of cork. Cork can last a long time without being damaged by water, however you should still clean up any standing water on cork flooring.
Is cork flooring sound resistant?
Cork is very good at noise reduction. Unlike other wood product floors you won’t get any creaks as the wood ages and the step noise is reduced. Cork is actually used in some music recording environments as noise reduction material.
Are cork wall tiles sound resistant?
Yes, cork wall tiles help reduce airborne acoustic noises.
Is cork flooring fire resistant?
Cork in its natural state has resistance to fire; however depending on what type of finish you use it can affect the fire resistance ability of your cork flooring. Furthermore, when cork burns it does not release toxic gases.
Are cork wall tiles fire resistant?
Cork in its natural state has resistance to fire; however depending on what type of finish you use it can affect the fire resistance ability of your cork flooring. Furthermore, when cork burns it does not release toxic gases. Flame Stop, Inc. produces a fire retardant that can be sprayed on to unfinished tiles to obtain a Class A fire rating. The product identification is 1-DS.
Is cork flooring a good insulator?
Cork is an excellent natural thermal insulator. Cork floors stay warm even when installed over cold concrete floors. Cork underlay is used under ceramic tiles to increase the insulation capacity of that flooring type. You won’t find any cold feet in the winter months with cork flooring.
Over which surfaces can I install my cork flooring?
Cork floating floors can virtually be installed over any type of surface if
properly leveled, cleaned and dried.
For cork tiles, the sub-floor must be completely flat and smooth and free of all paints, dirt, oil, grease and other foreign materials. If you have carpeting, rubber etc., it will need to be removed and either the floor will need to be sanded until smooth or a new plywood sub-floor be installed. If you have ceramic or stone tiles and they are secure and not loose, apply a patching cement over tiles making the surface free of all deflections, grout lines and tile cushioning.
(For further details see our installation guidelines)
Over which surfaces can I install my cork bulletin board?
Cork wall tiles can be installed over plywood, waferboard, cementboard, particleboard, treated lumber, drywall, brick veneers, imitation stone, tileboard, foamboard, ceiling tiles, & mdf paneling. Please contact our technical support for other substrates (1-888-955-CORK).
Can I install a cork floor over radiant heat?
Cork is a natural insulator so just by having it the floor will be warm. If you want to install radiant heat, that is not a problem. The floor may take slightly longer warm up but the heat will be retained efficiently. Floating floors tend to go through normal contraction and expansion as a unit since they are not attached to the sub-floor. Certain precautions need to taken to minimize the contraction and expansion: The radiant heating system should be turned on for at least 4-5 days before installation, the floor panels need to be acclimated in the room for about 3 days prior to installation.
Do cork floating floors require underlayment?
No. All AmCork’s floating floors have an integrated cork underlay and do not require any other underlayment, just a vapor barrier in the form of a plastic (PE) sheet.
Are cork floors affected by moisture and temperature changes?
Just like wood, cork floors are subject to expansion and contraction due to climate. Cork as a rule is more stable than wood flooring for the fact that when wood expands, it does so only in the direction of the grain. With cork, the expansion or contraction process is dispersed in all directions. With proper acclimation, installation and maintenance, any expansion/contraction will not be noticeable.
Will my cork floor fade in the light?
Yes, exposure to UV light as well as sunlight will cause color variations to cork; typically cork will lighten. This is normal and not a manufacturing defect. Area rugs and large furniture will block light exposure and cause uneven coloration. To minimize, furnishings and floor coverings should be moved periodically. Covering large exposed windows will help as well.
Can I install a cork floor in a basement?
In basements there is a high probability of occasional moisture migration
from the slab. Moisture can cause glue-down tile to delaminate and cup.
Therefore, tile is not recommended for this type of application.
For basements, we recommend the use of floating floors with a polyethylene (PE) film as a moisture barrier underneath.
Is cork flooring suitable for a kitchen?
Cork floors are fine for a kitchen. They are very comfortable to stand on and easy to maintain as well as hypoallergenic and sound absorbent. It is recommended that after installation an additional coat of sealer be applied to the floor. This will prevent dirt and spills from penetrating through the joins. Sweeping and damp mopping should be part of your regular maintenance program as grit could act as sandpaper and scratch your additional coat of sealer. If the floor starts to show signs of wear, simply apply another topcoat and this should bring back the original luster to the floor.
Are cork floors suitable for a bathroom?
Yes, cork flooring is recommended for use in bathrooms. Precautions should be taken to protect the floor from excessive spills and water. After installation, it is important that you seal the around toilets and showers using a clear stainable caulk. This will help in preventing water damage getting into the sub-floors or walls.
I’ve heard that cork flooring is great for hallways. Why?
Cork flooring can be installed virtually anywhere, but because of its cellular nature it naturally absorbs sound. And this can have a significant quieting effect in areas, such as hallways or entryways, which are normally associated with echoes.
What makes cork flooring a good option when thinking about falling and impact?
Cork flooring is cushion-like, made as it is of about 50% air that is locked into the microscopic cells which act as natural shock absorbers. This can be quite beneficial when you’ve dropped dishes and glasses. It can also have a positive effect when accidental human falls occur. For areas used by children or the elderly, this can be a major benefit.
How do I decide whether to use parquet tiles or floating floors for my application?
For installations below grade, over a radiant floor heating system or when a sub-floor would require costly preparation to install tiles.
The up-front cost per square foot of material is higher for floating floors. However, this is often offset by a reduction in sub-floor preparation costs and decreased installation time.
Floating floors are easy to install.
Parquet tiles are the preferred material for bathroom installations.
The material cost for tiles is lower than that of floating floors. However, sub-floor preparation for parquet tile installation must be meticulously clean, level, and unblemished. This degree of preparation can be costly and time consuming.
Parquet tile may be mixed-and-matched to create borders or a checkerboard effect. They are easily cut to size allowing for more creative and decorative installation options.
I purchased a house that has cork floors, can they be refinished?
If the cork floor is of the solid type, you will need to contact a wood floor finisher and sand the floor down to bare cork in order for you to recoat with a sealer. If the cork floor is veneered, you should make a thorough cleaning of the floor that will remove intensive soiling and wax residues. After the floor has been thoroughly cleaned, it can slightly sanded (with a fine sandpaper or pad) and recoated.
Is cork underlayment a good choice for soundproofing?
Absolutely, 2mm, 4mm and 6mm cork is being widely used for sound reduction in buildings. It is a very economical and effective way to meet building codes for sound control. Furthermore it’s a natural product. Cork underlayment can be used under many types of floorings like laminate, wood floors, linoleum, vinyl, tiles and marble.
What is the warranty for floating floor, cork floor tiles, and cork wall tiles?

How do I clean and maintain cork wall tiles?
Cork wall tiles used on a wall or as a bulletin board can be varnished with a food grade mineral oil made by Howard labeled "Butcher Block & Cutting Board Oil". You can purchase this product at any local hardwood store. Cork wall tiles do not require additional finishing however you can use this product to keep the material looking vibrant.
How often does a cork floor need to be refinished?
A well-maintained cork floor will last for decades. Depending on how much foot traffic the floor receives, you will need to reapply recommended polyurethane sealant approximately 7-10 years in average residential applications. This could be once every year or two in a busy retail location.
Are there any tips that help me to protect my cork flooring?
Yes, the following of these simple procedures will guaranty many years of
enjoyment of your natural cork flooring:
Protectors should be installed under chair and table legs; when using furniture with wheels, the floor must be additionally protected by using mats; heavy furniture should have non-staining glides or casters; steel wool or abrasives must not be used on the floor; a quality doormat at the entrance should be used to help protect the cork floor from outside grit and sand; adequate protection should be taken when moving appliances or large pieces of furniture around the floor; cork, as a natural product, may change color when exposed to direct sunlight, so use blinds or curtains to minimize this effect.
