karuun®
A Material
Revolution
Rat­tan’s structure is compara­ble to a bundle of tubes. The rat­tan palm can transport wa­ter up to 200 me­t­res th­rough its long
capillaries. out for space utili­ses this natu­ral pro­perty for its one of a kind, patented tech­nology. When the capillaries are injected wi­th various bulking agents,
rat­tan is trans­formed from a wood wi­th limited use to a ver­satile, innovative mate­ri­al.
karuun is fir­mer, har­der, weather-resis­tant and even has a new cha­racteristic co­lo­rati­on. karuun pres­ents an alternative
to other mate­ri­als, wi­th
ap­p­licati­ons in multiple are­as.

karuun col­or embod­ies a truly nov­el aes­thet­ic char­ac­ter. Since the col­or is not applied to the surface but actually injected through the cap­illar­ies, karuun col­or can be processed into semi-fin­ished prod­ucts such as weav­ing ma­te­rials, ve­neers and boards. Surface imper­fections can be simply sanded away and seams are nearly invis­ible due to the uniform na­ture of the fibers. Having the option to mix additives such as nat­ural waxes and oils into the paint, en­sures simple surface fin­ish­ing and main­tenance.
One of the dis­tinct advantages of karuun is its high degree of bendability. By treating it with heat and steam, boards and rods can be eas­ily shaped with very lit­tle force or energy. karuun col­or prod­ucts are not suit­able for out­door use!

karuun shine is translucent, which is unique among natural materials.
karuun® veneer –
superior aesthetic standard
 
 
 
 
 
The homo­genous na­ture of the ma­terial captures the cur­rent zeit­geist. Un­like con­ven­tional ve­neers, no vi­sible jo­ints are cr­eated when pro­ducing veneer in karuunby virtue of its char­acter­istic linear fibre structure. Its ae­sthetic grace pre­sents comp­letely new design pos­sibil­ities.











Thanks to a pat­ented tech­nique it’s pos­sible to in­cor­porate a unique strip pat­tern in the ma­terial ac­cording to colour pref­erences.

karuun® 3D veneer –
three-dimensional shaping
 
 
 
The natural fibre struc­ture lends the ma­terial its all-im­por­tant pli­ability; the combination of capil­lary treat­ment and a spe­cial vis­cose non­woven fa­bric means that the in­nov­ative veneer boasts un­pre­cedented three-di­men­sional form­ability. In con­trast to clas­sic vene­ers, spher­ical ob­jects can be eas­ily pro­duced as well.

Semi-finished products
made of karuun® color
karuun color embody a truly novel aesthetic character. The new and unique process used by out for space means that cus­tomers are able to choose almost any colour.
Surface imperfections can be simply sanded away, since the paint is distributed throughout the material and is not only applied to the exterior.

The Debut of
karuun®color
kc Col­lection is the first col­lection by out for space made from the new ma­te­rial, karuun color. The col­lection fea­tures four prod­ucts, all of which centre around the unique prop­er­ties of this new ma­te­rial. The col­lection’s design is char­ac­ter­ised by a clear and reduced design
language, not to mention the nov­el use of rattan as wood­en boards. kc Col­lection is therefore not only eas­ily dis­tinguish­able from tra­ditional rattan prod­ucts, but the debut of karuun color also rep­resents an innovation in fur­ni­ture.

Approach & Profile –
The Rediscovery of Materials
In Asia rattan is tra­ditionally used as a ma­te­rial for fur­ni­ture and is the foundation for many pieces. With the advent of ma­te­rials such as polyrattan, howev­er, nat­ural rattan has sadly lost some of its for­mer popular­ity and signif­icance.
Especially in Eu­rope, the prop­er­ties, production processes and po­tential sustainability of the ma­te­rial are almost forgotten today. For out for space, howev­er, rattan is a source of unlim­ited po­tential and far more uses than for­merly imag­ined.

Sustainability –
an Almost Forgotten
Aspect
 
 
Rat­tan or Rotan (ind.-malay) grows al­most ex­clus­ively in rain­forests and 80 % of glob­al rat­tan pro­duc­tion is in In­done­sia. The most im­port­ant genus is nat­ive to Africa and Asia and is called Cal­amus. With about 600 dif­fer­ent spe­cies, Cal­amus is the most di­verse palm.
It is widely un­known that cer­tain spe­cies of rat­tan grow to a dia­met­er of 100 mil­li­meters and can reach a total length of 200 meters, mak­ing it one of the longest plants on the plan­et! Thin rat­tan called ped­dig is tra­di­tion­ally used for wick­er­work and thick­er rods are used for fur­niture frames.
The wood of the rat­tan palm is unique in its in­tern­al struc­ture. Un­like oth­er woods, the ca­pil­lar­ies of rat­tan are long single tubes which travel the length of the en­tire plant and sup­ply it with wa­ter. Due to this, rat­tan is very elast­ic when made wet and even more so when ex­posed to heat or steam. This makes fur­ther pro­cessing ef­fi­cient and gives rat­tan ad­vant­age­ous prop­er­ties such as its light weight, elasti­city and high bend­ab­il­ity.
On the oth­er hand, it isn’t pos­sible to treat the sur­face of un­pro­cessed rat­tan with con­ven­tion­al meth­ods be­cause the or­tho­sili­cic acid in its skin pre­vents ad­he­sion.
If the out­er lay­er is re­moved, sur­face treat­ment such as paint­ing and dye­ing is pos­sible, but even then the col­or will fade with time and there is only lim­ited pro­tec­tion against weath­er­ing and us­age.
This is due to the mate­ri­al’s large pores, which make it sus­cept­ible to mois­ture and mold. The elast­ic and supple wood lent to rat­tan by its poros­ity also lim­its its field of ap­plic­a­tion. Even stronger rat­tan rods with dia­met­ers of over 30 milli­meters, used as chair legs for ex­ample, need ex­tra struts to give them ad­di­tion­al sta­bil­ity.
Rat­tan grows very quickly and has sig­ni­fic­ant ad­vant­ages over oth­er types of wood. For ex­ample, rat­tan nat­ur­ally forms a sym­bi­ot­ic re­la­tion­ship with its neigh­bor­ing plants in the rain­forest, such as the cen­tur­ies old Mer­anti Tree. The rain­forest is es­sen­tial for rat­tan: this means that cul­tiv­at­ing rat­tan would pro­mote rain­forest pre­ser­va­tion or even re­for­est­a­tion as op­posed to the ex­pan­sion of mono­cul­tures in­to the rain­forest. Pur­chas­ing rat­tan products in­dir­ectly con­trib­utes to the health and pre­ser­va­tion our world’s rain­forests.
