purenit® - diamond among smart materials

Construction and thermal insulation of the first kind for components and building parts.

purenit is a highly compressed smart material based on PUR/PIR rigid foam providing a high thermal insulation value. purenit is made of residual material from production runs during a closed process chain convincing through its sustainability.

Facts for processing


Effortless and accurately, on all commercial wood-working machines.


An HSS drill bit is sufficient to pre-drill screw holes.


Saws easily and precisely.  Water-jet cutting also possible.  For a longer stability, we recommend carbide tools.


Practically no restrictions when bonded/coated/laminated with other materials.  Ideal carrier medium for laminated plastics/materials.


Suitable for processing with all commercial adhesive/bonding systems.


purenit even withstands solvent-based paints and varnishes and in addition, is an ideal plasterboard for all current plaster systems.
