Cork granules.

Building products

An ancient material projected to the future

This extraordinary raw material originates from the cork oak tree, from which, thanks to the skill of expert craftsmen, the outer bark is extracted every 9/10 years. This operation does not harm the plant, as it naturally regenerates its bark. Cork is, therefore, a renewable resource par excellence.

The use of cork granules in the construction industry is very versatile. They are used in the production of thermal-insulating panels and can be mixed with rubber in order to produce insulating mats for both civil and industrial use. Frequently, they are used in the production of lightened screeds (for example, in renovation and restoration projects of old buildings, the use of lightened floors reduces the loads on the structures) or be laid in attics.

Advantages
and benefits

The use of cork granules for thermal insulation is an extremely advantageous option for a housing unit, especially from an economic point of view.

This type of insulation costs considerably less than aesthetic interventions, and it also offers extremely positive long-term benefits.

Cork Line provides a variety of cork granules differentiated by size and density, but mainly two types are particularly in demand by our customers:

3-6 mm granule with density ranging from 100 to 110 kg/mc, available in raffia bags of about 10 kg.
4-20 mm granule with density between 130 and 150 kg/mc, available in both approximately 10 kg raffia bags and big bags.
