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

karuun® Products


We sell semi-finished products made of karuun® to modern material-thinking companies.

We believe that active protection

of the environment can only work

if the local population benefits.


karuun® embodies the ability to combine community, economic and ecological interests. This balance is in tune with the times and provides an excellent angle to all industries who can use karuun® to challenge the customer requirements of today and tomorrow.

The main cause behind deforestation is the local population’s need for resources and a better livelihood. out for space believes that sustainable reforestation and active protection of the environment can only work if the local population benefits.

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 attitude spurs us on to take responsible ecological and social action.

karuun® is minimalistic and poetic – kinetic

object for form magazine by Uli Budde

Berlin-based designer Uli Budde has designed a minimalistic and poetic kinetic object using an innovative rattan material, karuun®, which is bent into shape by means of heat-steaming, for form

Edition #5. The green-dyed capillaries provide a graphical surface and on the grooves of the turned edges, they show off the structure of the material particularly well.

karuun® Lab

The karuun® lab is a digital workshop for all designers, architects and engineers who want to experiment with karuun® virtually or physically to develop future-oriented products.


Please understand that we can only undertake projects with a high degree of implementation.

Textures for CAD and 3D programs, data sheets and tutorials are available here.

We look forward to working with partners who want to support the development of karuun® as a valuable, intelligent and innovative material.

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’s possible to treat the material with active substances, which before now could not be effectively incorporated into the cell structure of conventional natural material.

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

Here you find the textures for karuun® shine and karuun® stripe/karuun® 3D, each in bump, color and normal map, ready to be implemented in Cinema 4D, Rhino, Grasshopper or any other common 3D program.

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.
