Isolation by nature

Cellulose - a product from nature. As the main component is out of plants and trees, it serves to stabilize the cell walls. Cellulose is the most common organic compound. No trees without cellulose. No paper without trees. No natural insulation without paper.

ISOCELL is natural thermal insulation made from cellulose fibers, which is created by recycling clean, unmixed newspaper. Coarsely fibered, mixed with mineral salts and ground in a mill, Isocell cellulose makes it rot-proof and fire-resistant. Production takes place in compliance with the strictest quality criteria in our own plants in Austria, Belgium, France and Sweden. MORE

Cellulose - Best thermal isolation (.pdf)

Cellulose insulation means natural thermal insulation made from cellulose fibers, made from clean, sorted daily newspaper. So the basic material is wood. The sorted paper is roughly frayed, mixed with mineral salts and ground in a mill. The production is subject to the strictest quality criteria through external and internal monitoring for national and European technical approvals. ISOCELL cellulose insulation does not mold, is rot-proof and fire-resistant.

The best thermal insulation values:

ISOCELL cellulose insulation is characterized by a particularly low thermal conductivity (AT / EU: 0.038 W / mK, DE: 0.039 W / mK). But every isolation is only as good as its weakest point. That is why ISOCELL cellulose fills even the narrowest gaps and crevices. This results in a seamless, thermal bridge-free insulation mat. MORE

The best heat protection:

The high storage capacity of ISOCELL cellulose insulation means that the sun's heat reaches the interior much more slowly than with conventional insulation materials. Even attics stay cool until late into the night. MORE

Effective and environmentally friendly:

ISOCELL cellulose insulation already protects the environment during production. In comparison to other insulation materials, the primary energy input is much lower: a sixth is saved compared to polystyrene, a third compared to glass fiber. MORE 

Cellulose insulation saves time and money

Extremely low thermal conductivity and settlement security, even with large insulation thicknesses - The special ISOCELL injection system enables seamless and waste-free insulation.

The optimal sound isolation

Tests prove: ISOCELL cellulose insulation provides up to 7 dB better sound insulation values for partition walls than conventional fiber mats. MORE

High building fire protection

ISOCELL cellulose isolation is also asserting itself more and more in fire protection against conventional insulation materials. This is shown by successfully carried out fire protection tests on components from F30 to F90. With the EN classification B-s2-d0, ISOCELL cellulose insulation achieves one of the best possible ratings for flammable insulation materials. Fire tests, carried out at the Institute for Fire Protection Technology and Security Research GmbH in Linz, as well as in-house fire tests gave the same picture. ISOCELL cellulose insulation does not burn. It just chars the outer layer. MORE

Versatile insulation

ISOCELL cellulose insulation is versatile. For insulation of sloping ceilings, last floors and walls or as insulation for buffer storage, installation shafts, vaulted ceilings e.g. in churches.

Cellulose insulation blown in properly

ISOCELL cellulose insulation works very simply. The blowing specialist comes to the construction site with his truck and brings everything he needs. Blowing machines and cellulose fibers. The builder, carpenter or drywall specialist has already prepared everything in advance. The ISOCELL blowing machine remains in the truck and is filled with cellulose there. The specialist brings the injection to the desired position and starts. The cellulose fibers matted in the construction to form a seamless insulation mat. No matter whether floor, ceiling or wall - it is always the same product.



Isocell cellulose has a moisture-regulating effect. It is not only very water vapour permeable, it can also transport moisture in the fibre. It accomplishes this without losing its insulation qualities.




ISOCELL cellulose is charactarised by a particularly low heat conductivity

  • AT/EU: 0.038W/mK
  • DE: 0.039 W/mK
  • CH: 0.038 W/mK




The rooms stay cool in the summer, including the under-roof areas. ISOCELL cellulose insulation provides maximum performance in heat protection, as in other aspects. And that with enormous endurance, so far without material fatigue.
