Cork: A Material for Interiors, Hospitality and Design.

Cork is harvested from the bark of cork oak trees - a process that leaves the tree intact. The bark regenerates and can be harvested again every nine years.

Cork harvesting process from the tree

01 - Origin

What cork
actually is.

Cork comes from the bark of Quercus suber - native to Portugal and Spain. It is stripped by hand every nine years without cutting the tree.

We work with this material in India, translating a Mediterranean raw resource into products for Indian interiors, hospitality environments, and institutions.

02 - Material Structure

Inside the material.

Cork is made of millions of microscopic air-filled cells per cubic centimetre. Each cell is sealed by suberin - a natural waxy compound that resists moisture and compression. This structure accounts for cork's acoustic, thermal and tactile properties.

04 - Material Formats

Types of cork materials

Cork is processed into different formats depending on application requirements.

Natural Cork Sheets

Full natural grain. Used for surfaces, boards and product components.

Agglomerated Cork

Granulated cork compressed without synthetic adhesives. Structural and surface use.

Decorative Cork Panels

Architectural surface panels in varied finishes for interior wall installation.

Technical Cork Composites

Cork combined with other materials for acoustic backing, vibration damping and thermal underlays.

Our Design Library provides closer detail on these materials and their specifications.

05 - Common Questions

Frequently asked

Material behaviour, limitations, and working with cork in India.

Full FAQ
Is cork durable?

Cork is resilient and compressible. Surface marks tend to blend into the natural grain rather than read as visible damage.

Is cork waterproof?

Cork resists moisture but is best suited to controlled interior environments. Sealed surfaces are recommended for kitchens or high-moisture contexts.

Can cork be used on walls?

Yes. Cork panels are used for interior wall surfaces and acoustic treatment, installed as sheet cladding, modular panels or pinboard systems.

Does cork absorb sound?

The cellular structure reduces sound reflections. Performance depends on thickness, installation method and surrounding surfaces.

Is cork available in India?

Yes. We supply cork materials and products pan-India from our studio in Guwahati, Assam.
