Natural Perfection

Using highly energy-efficient technology, we transform the rattan’s natural structure into a material which is both versatile and innovative.


We call this new material karuun®. As a non-timber material, these characteristics place karuun® at the forefront of natural alternatives to plastic. The combination of outstanding versatility and an eco-friendly lifecycle make karuun® thoroughly deserving of its indigenous name, “the hidden treasure”.

karuun® is the start of modern material thinking, be part of it now!

From Rattan to karuun®

A cross-section of rattan looks like a bundle of tubes. These tubes are in fact capillaries which allow rattan to transport water up to 200 metres. out for space utilises this natural attribute for its one of a kind, patented technology.


When the capillaries are injected with various bulking agents, rattan is transformed from a non-timber product with limited use into a versatile, innovative material – karuun®.


With a variety of applications in different fields and industries, karuun® is at the forefront of natural alternatives to materials like plastic.


Processing karuun® rods into blocks opens the door to a multitude of new applications which harness the material’s natural flexibility and light weight.


The homogeneous structure of the fibre is unique. Depending on the direction in which it is cut, three different karuun® products with various possibilities can be created.

We sell semi-finished products made of karuun® to industries which manufacture custom products with karuun®.

karuun® stripe

Superior Aesthetic Standard

The tube-like structure of karuun® allows surfaces with custom dimensions to be manufactured in a process which leaves no visible joints or offcuts. This web of capillaries can also be injected with any colour variation and processed into a karuun® surface. karuun® stripe is perfect for use as on flat surfaces such as boards or panels, its applications in interior design are boundless, while its sustainability as a material captures the current zeitgeist.


The aesthetic elegance of karuun® stripe expands the horizons of design in both traditional and high-tech industries.

Features and benefits of karuun® stripe

  • available in almost every colour
  • post-formable into shapes with extremely tight angles
  • can be joined without leaving any visible transitions

karuun® shine

Translucent Wooden Board

The structural composition of rattan is utilised to produce karuun® shine: a lightweight material which is simultaneously permeable to both air and light while also being strong and pleasant to the touch. Besides, the highly stable end-grain is also extraordinarily formable.


The unique capillary structure sets the foundation for application areas ranging from tailor-made, high-tech acoustic protection on one end of the spectrum, to futuristic lighting design and innovative flooring on the other.

Features and benefits of karuun® shine

  • translucent
  • permeable to air and light
  • sound absorption
  • malleable

karuun® 3D

Three-dimensional Shaping

The natural fibre structure lends the material its all-important pliability; the combination of capillary treatment and a special nonwoven viscose fabric means that the innovative surface boasts unprecedented three-dimensional formability.


Spherical objects from as small as a button to as large as a deep-drawn formed component can be manufactured without having to worry about splintering. Something which, until now, was only possible using artificial composite materials.

Features and benefits of karuun® 3D

  • outstanding spherical objects
  • comparable to artificial composite materials

Rattan Cultivation

An Almost Forgotten Aspect

karuun® is processed from rattan, a climbing palm which grows quicker than trees and whose cultivation provides significant advantages over other types of wood and non-timber products.


Rattan relies on biodiversity and cannot flourish in a monoculture, so supporting its cultivation actively helps preserve our planet’s rainforests and gives the local community a sustainable income. Purchasing karuun® products directly contributes to the health and preservation of earth’s rainforests.

Rattan naturally forms a symbiosis with neighbouring trees; it needs the rainforest to thrive. As a natural raw material, it grows like a liana and is harvested in the most eco-friendly way – by hand by local farmers. Growing and harvesting rattan benefits these farmers, so protecting the environment is in their best interest.

The karuun® Cycle

Based on Partnerships

Driven by globalisation, the steady growth of the global economy poses major challenges, especially to our ecosystem. Future-oriented companies are already responding to these challenges and reacting to changing consumer behaviour. This shift in attitudes spurs us on to take responsible ecological and social action.


out for space actively embraces these economic and ecological changes, which is why we’ve developed the karuun® cycle. Together with our partners, Fairventures Worldwide and the VIVERE Group, we’re spearheading projects to guarantee local people a long-term income by monitoring existing rainforests and promoting reforestation.

karuun® Processing Technology

Our processing technology takes advantage of rattan’s characteristic vascular bundles, making it possible to treat the entire cross-section of rattan rods for the first time.


It is unique among processing techniques, as the treatment is carried out from the inside to the outside via the vasculature. This not only ensures the material is permeated effectively but it also requires very little energy. It is possible to treat the material with active substances, which before now could not be effectively incorporated into the cell structure of conventional natural material types.

The materials of the future are significantly influenced by trends, as well as economic, political and societal conditions. Our task at out for space is to anticipate, understand and integrate the future material needs of customers into innovative technologies and products. If you also work on this wavelength too, we would gladly develop a new karuun® with you.

karuun® Texture

Through continued improvements to karuun® and our manufacturing processes, karuun® has the potential to become relevant as a new and innovative natural non-timber material.


Therefore, we’re on the lookout for designers who are keen to implement karuun® materials in their new designs and create new applications.

The surface bundle is downloadable in different file formats on request and you can implement the texture in Cinema 4D, Rhino, Grasshopper and other programs.

Working with karuun®

Tutorial and Datasheets

The mechanical characteristics of karuun® vary corresponding to the specifications. For best results, we suggest you test karuun® in advance, depending on the purpose and use.
