Initial Care

Seal the floor: Most cork floors come pre-finished, but if your cork is unfinished, apply a protective sealant. This helps prevent stains, moisture damage, and wear.

Allow curing time: Avoid heavy traffic for a few days after installation to let adhesives or finishes set properly.

When was cork firstly used?

Throughout History there have been numerous references to this product and its varied applications. In 3000 BC, cork was already being used in fishing tackle in China, Egypt, Babylon and Persia. In Italy remains dating from the 4th century BC have been found that include artefacts such as floats, stoppers for casks, women’s footwear and roofing materials. Also dating from that period is one of the first references to the cork oak, by the Greek philosopher Theophrastus who, in his botanical treatises, referred in wonder to “the ability that this tree has to renew its bark after it has been removed”. Later, in the 1st century CE, the Roman naturalist Pliny the Elder made extensive reference to cork oaks in his celebrated Natural History. He explained that in Greece the trees were adored as symbols of liberty and honor, for which reason only priests were allowed to cut them down. In the same work, we can read that cork oaks were consecrated to the god of Olympus, Jupiter, and their leaves and branches were used to crown victorious athletes.

In Pompeii, the Roman city destroyed by the brutal eruption of Mount Vesuvius, wine amphorae sealed with cork have also been found. Later, during the Age of Discoveries, the builders of the Portuguese ships and caravels that set sail in search of new worlds used cork oak wood for the parts that were most exposed to inclement weather. They claimed that the "sôvaro", as it was called then, was the best wood for masts and yards: besides being exceptionally strong, it never rotted.

What is cork?

Cork is the outer bark of the evergreen cork oak (Quercus suber). This variety of oak grows mainly in Portugal, Spain, southern France, Italy, and the Maghreb. It consists of a tight web of up to 40 million cells per cubic centimetre. The cell membranes retain gas, giving cork its capacity to float, insulate and re-expand quickly after compression.

What are cork’s main characteristics?

Cork is natural raw material, 100% recyclable and biodegradable. It is a very light raw material, it can float. It is very flexible and has elastic memory: it can be compressed to around half its thickness, without losing any flexibility, and decompressed returning to its original shape. It is also practically impermeable to liquids and gases. It is very decay resistant, namely to moisture. It is an excellent thermal, acoustic and vibration insulator. In construction, it has clear advantages in regard to the quality of buildings, indoor air and comfort, and may be used in the waterproofing of infrastructures, foundations and underlays, in acoustic and thermal insulation and the final coverings for floors, walls, ceilings and roofs.

What is cork used for?

Due to its characteristics, cork is ideal for a large number of applications, such as a closure for wine and spirits, cork is used in industries as diverse as floors (floating floor and cork tiles), shoe manufacturing, construction (insulator planks), automotive (gaskets), leisure (fishing rods), upholstery (cork textile) and a wide range of cork finished articles (handbags, wallets, accessories).

When is cork ready to be used for manufacturing products?

Once the trunk’s circumference has reached 70 centimeters, the cork can be stripped. The tree is then harvested in regular cycles throughout its lifespan. Each cork oak provides an average of 16 bark strippings. Traditionally the first stripping of the cork barks occurs when the cork oak is 25 years old and the process can be repeated every 9 years. The cork oak can live up to 250 years old and each tree can produce up to 1000 kg of raw material in a lifetime.

What are cork’s main benefits?

Cork is natural, recyclable and biodegradable. No natural or man-made material replicates its properties. In a world of growing environmental awareness, the cork oak survives without the use of chemical herbicides, fertilizers or irrigation. Moreover, it’s the only tree that regenerates after harvesting. Cork retains unique qualities of flexibility, elasticity and compressibility. Its extreme resilience, impermeability, lightness and insulating efficiency make it ideal for a wide range of applications.

Is cork good for your health?

Yes. Research carried out by University of Porto reveal that cork has antioxidant and anti-carcinogenic properties. When applied to flooring and footwear, cork contributes to improve posture and reduce physical effort.

Where can we find cork oak forests around the world?

Cork oak forests are delicately-balanced ecosystems, very specific that persist only in the Mediterranean region (Algeria and Morocco) and particularly in the south of Europe as in Portugal, where is the largest cork oak tree area (around 730 thousand hectares representing 33% of the whole cork in the world).

In Portugal, where can we find cork oak forests?

In Portugal, cork oak forests represent around 21% of the total forested area and are responsible for the production of more than 50% of the cork consumed throughout the world. These forests have species designated by Quercus (Quercus National Association for Nature Conservation) – large areas of holm oak (Quercus rotundifolia), small areas of Pyrenean oak (Quercus pyrenaica) and, above all, cork oaks (Quercus suber L). Of the entire flora in cork oak forests, the cork oak is the most numerous specie and can be found throughout the country, from Minho in the north to the Algarve in the south, except in the harshest areas of Trás-os-Montes and the coldest hilltops and slopes of north Portugal. However, cork oaks are, most commonly, associated with the landscape of the Alentejo, where they indeed grow on a large scale.

Did you know cork oak forest is a protected area?

From early as the 13th century, Portugal can be proud to have been a pioneer in environmental legislation where the first agrarian laws protecting cork forests have been enacted in 1209.

Considered a national heritage, cork oak forests have been legally protected for centuries (Decree-Law 169/2001). Today, the trees may not be cut down and incentives are available for the planting and management of cork oak forests. This initiative, pioneered by Portugal, was clearly a good decision, since the harvesting of cork has become an industry of great economic importance and Portugal has become the main international cork exporter.

Is cork flooring a healthier alternative to other flooring?

Yes. Natural cork flooring is a great alternative for allergy suffers since dust, mold, mildew and insects are unable to establish themselves as they do in carpet.

Can cork flooring resist heavy furniture or high heels?

Yes. Cork has what is referred to as “cellular memory”. Just like “memory foam mattresses”, cork will spring back after being heavily compressed. In fact, it will regain 95% of its original form after being compressed down to 50% of its thickness. There is no other natural flooring product that can do that. But like other flooring options we recommend you protect your floors by using furniture coasters under your semi-permanent furniture (sofa, stove, refrigerator, armoire, china cabinet, etc.) and self-adhesive felt pads under your moveable furniture (chair legs, TV trays, etc.).

Are cork floors affected by moisture and temperature changes?

Yes. Just like wood, cork floors are subject to expansion and contraction due to climate.

Is the color of all cork flooring consistent?

No. Just like oak flooring (cork being in the oak tree family) comes in many shades. You need to keep in mind that each cork tree sheds its cork-bark in its own unique way. Shade variations are an inherent and attractive. This is a standing characteristic of natural products – whether cork, wood, bamboo, slate, marble or granite; color variations are to be expected.

Does cork fade in sunlight?

Yes. Cork fades when exposed to UV light. Direct sunlight produces the most dramatic changes whereas indirect sunlight will also have an effect. Natural cork floors show the greatest changes. Colored, or stained cork, is more likely to retain its color for a much longer frame of time.

What makes cork such a good insulator?

Air. The cellular nature of cork means it is full of air. Air is a semi-conductor…or in our case, a semi-insulator. This allows it to insulate against temperature and sound. This makes for warmth underfoot and almost silent footfalls.

How do you clean a cork floor?

You can use a slightly damp mop with a non-abrasive pH neutral floor cleaner. Stay away from the heavy-duty cleaning products. They will dull your finish much faster. A glue down tile cork floor is considered “waterproof”. With this floor you can use more water.

Can you install vinyl flooring outdoors?

Even if using waterproof vinyl flooring, we do not recommend vinyl flooring for outside or semi-outside areas. UV rays can cause fading and continuous weather can damage the flooring over time.

Will vinyl flooring expand?

Some vinyl flooring like Corkart will not expand and contract like other flooring types unless under extreme conditions. We will recommend leaving a small expansion gap around the perimeter for such extreme conditions, but the likelihood for expansion is very small.

Can I install vinyl plank flooring over carpet?

Vinyl flooring cannot be installed over any high pile carpet. The “squish” of a plush carpet will prevent vinyl planks from locking properly. However, if the carpet is a tight, low pile style, then thicker, tighter locking, vinyl planks may be suitable for installation.
