A progressively open market demands constant adaptation to new techniques and technologies and the capacity to always produce QUALITY.

Complete satisfaction of its customers is GRANORTE’s most important aim and is, unquestionably the most important factor in our growth. Therefore we adapt constantly so that we can offer increasingly competitive products with high quality standards.

An efficient control system guarantees the quality, from raw materials to finished products, ensuring that they are produced according to Internal Specifications and International Standards.
Nevertheless we do not see the question of QUALITY as simply following Standards, but rather as a culture resulting from a continuous process involving all the departments of the company.


Total customer satisfaction:
GRANORTE believes that customers establish Quality. It shall be our aim to reinforce partnership relations with completely satisfied customers.

Continuous improvement:
We shall focus on continuous improvement of our process-oriented organization.

Promotion and education:
GRANORTE shall encourage teamwork and the communication between all levels of the organization, developing education and awareness to Quality of all employees.

Environmental commitment:
We shall promote the social and external environment integration of the company and all its members.

Environmental questions are of great importance to GRANORTE. Cork itself is a natural renewable, environmentally friendly material. Therefore, our environmental efforts are focus on two fundamental areas: business practices and product design. Moreover, we do not just talk about environmental protection; we put it into practice trough a sound environmental corporate culture that reduces the environmental impact of the manufacturing of our products and promotes the social and external environment integration of the company.

Low water consumption, recycling and reusing;
The use of process water, which mostly arise during the cleaning of manufacturing equipment, have been dramatically reduced during the last few years. This water is not discharged; instead it is contained, treated and reused.

Reduced solvent content;
We use exclusively solvent-free lacquers and binders with solids content between 98 and 100 %. The only solvent used on the cleaning of equipment is recycled and reused.

Cork powder;
Powder from processing and handling cork is filtered, keeping emissions to air very low. The powder is then used as a burnable fuel in the production of the thermal energy needed in our production facilities.

Packaging material;
Our packaging is about 100% corrugated cardboard. This material, marked with the Resy symbol, can be recycled without any problems.

Substrate materials;
As a substrate material of our floating floor production line (HDF) we use only high quality, low pollutant content E0 and E1 quality fibreboard.

Purchasing policy;
Granorte’s policy is to ensure that the supply of forest raw material is coming only from responsible managed sources.

Other important issues;
Environmental work also includes the questions of power consumption, transportation and the reduction of waste through better sorting and recycling.

In all our investment decisions, safety and environmental questions are given a high priority.

Since 1972, our development through the years has been constant. Starting as a mid-sized granulated cork producer, we have developed into one of the key players in the cork flooring business. We still produce and export granulated cork, and one of our first customers is still our client. Today, GRANORTE is mainly a cork coverings producer and our main product is undoubtedly the floating floors. Here are some figures regarding our company:

Cork is the outer bark of the cork oak tree, Quercus Suber L, which grows mainly in the Mediterranean region of the world. The bark is a vegetal tissue composed of an agglomeration of dead cells filled with air and lined with alternating layers of cellulose and suberin.

The use of cork as a raw material dates back to the Phoenician and Greek times. Because of its use as wine bottle stoppers, cork began to be known all over the world. In fact, it is the only material that manages to make a perfect sealing during the ageing of the wine.

Today, cork represents for Portugal a valuable resource being one of the most important exporting products.

Cork oak forests cover approximately 2.5 million hectares primarily in seven countries: Portugal, Algeria, Spain, Morocco, France, Italy and Tunisia.
This tree has a life span of about 250 years. Each cork tree must be 20 to 25 years old before it can provide its first harvest of cork bark called “virgin”. This type of cork has a hard and irregular structure. After extracting the virgin cork a new layer of cork starts generating.
A typical tree produces several hundred kilograms of cork at each harvesting and will survive for many generations. The cork harvesting is made in a sustainable manner and does not harm the tree in any way.

Cork production is assured with new plantations every year. Trees are never cut down or removed without strong government intervention, which prohibits this activity.
Portugal, which produces more than 50% of the world’s cork, has been particularly careful with this resource. The first Portuguese regulations protecting cork oak trees date to 14th century.

With the increasing concern for the environment, cork oak remains the only tree whose bark can regenerate itself after harvest leaving the tree unharmed. It is truly, a renewable, environmentally friendly resource. Furthermore, the cork oak tree has the remarkable capacity to retain carbon and a harvested cork tree fixates almost five times more carbon. This exceptional characteristic makes cork a naturally sustainable product and its use contributes to the preservation of a unique habitat in the world.

The cork oak forests are well-adapted to the semi-arid regions of southern Europe, preventing desertification and providing the perfect habitat for many animal and plant species, including some rare species in extinction.

Preserving the cork oak forest areas, and the cork’s economical viability, is essential to maintain the biodiversity, avoiding desertification and promoting regional social stability.

The role of cork in preventing the global heating is significant. The cork bark of the tree regenerates itself after harvesting and it is known that a harvested cork tree absorbs 3 to 5 times more carbon. A recent study indicated that Portuguese cork forests can absorb 4,8 million tons of carbon each year and it is estimated that Mediterranean cork forests can absorb over 14 million tons of carbon per year.

The cork industry itself is truly eco-efficient. All cork is used, not one gram of cork is wasted. Cork by-products, are used in different products (flooring, decorative items, automobile industry…), and recycling (post-industrial and post-consumer) is a common practice. Even cork dust is used to generate energy.

The bark of the cork oak tree has a unique honeycomb structure composed of tiny cells filled entirely with air. The properties of cork derive naturally from the structure and chemical composition of the extremely strong, flexible membranes that are waterproof and airtight.

It should be remembered that each cubic centimetre of cork’s structure contains between 30 and 40 million cells.
Because about 89% of the tissue consists of gaseous matter, the density of cork is extremely low, in the order of 0.12 to 0.20.

Some of cork’s most unique and useful properties are:

Cork is light and will float on water. For many thousands of years, this has been its most evident and most celebrated characteristic. In antiquity cork was used in fishing equipment.
Elasticity and Resiliency:
The cellular membranes are very flexible, making the cork both compressible and elastic. These characteristics, in alliance with others, largely explain how cork has become indispensable for stoppers.
This capacity means that the cork can be fitted perfectly against the walls of the bottleneck. When cork is subjected to strong pressure the gas in the cells is compressed and reduces considerably in volume. When released from pressure cork immediately recovers its original volume.
The presence of suberin (a complex mixture of fatty acids and heavy organic alcohol) renders cork impermeable to both liquids and gases. As a result it does not rot, and may therefore be considered one of the best seals available.
Insulation & fire retardant qualities:
Cork has one of the best insulating capacities, thermal and acoustical, of all natural substances. This is due to the fact that the gaseous elements are sealed in tiny, impermeable compartments, insulated one from the other by a moisture resistant material.
Cork is a natural fire retardant as it does not spread flames and does not release toxic gases during combustion.
Resistance to wear:
Cork is also remarkable resistant to wear and has a high friction coefficient. Thanks to the honeycomb structure of the suberose surface it is less affected by impact and friction that other hard surfaces.
Cork does not absorb dust and consequently does not cause allergies nor pose a risk to asthma sufferers. It is constitutionally inalterable and so its efficiency is guaranteed.

First utilised centuries ago as wine stoppers, cork has developed into a key material in many industries including construction, high-technology and even fashion.
In its several forms – natural, composition, granulated and rubber/cork – cork’s attributes cannot be found in any other single source, making it superior to many synthetic substitutes and an essential element for many purposes.
Cork can be adapted to various products specifications and techniques and many of its uses may be invisible to our eyes. Cork is really an all-purpose problem solver for a vast number of purposes:

Vibration Control
Weight Reduction
Sound Dampening
Energy Conservation
Load Bearing

Engineers, architects, builders, scientists, fashion designers, interior designers and manufactures of housewares, sporting goods and leisure products select cork because it is the best material for their unique and demanding applications.

Thanks to their superb properties, cork products have entered our everyday lives.
