We keep tight
Cellulose insulation stands for natural thermal insulation made from cellulose fibres and manufactured from clean, sorted newspapers. The basic material is therefore wood. The paper is supplied pre-sorted, is broken into fibres, mixed with mineral salts and ground in a mill. Production is subject to the most rigorous internal and external quality controls to maintain regulatory compliance for the German, Austrian and European market.
The best thermal insulation values
ISOCELL cellulose insulation excels with a particularly low coefficient of thermal conductivity (AT/EU: 0,039 W/mK, DE: 0,040 W/mK). However, all insulation is only ever as good as its weakest points. With cellulose insulation even the smallest gaps and cracks are filled. The result is insulating matting without voids, free from thermal bridges.
Excellent thermal protection
The high storage capacity of ISOCELL cellulose insulation results in a considerably delayed transfer of radiated warmth from the sun. Even attic rooms remain cool until far into the night.
Even during production ISOCELL- cellulose insulation is environmentally friendly. The use of primary energy is much lower in comparison with other insulation materials: compared with polystyrene one sixth is saved, one third in comparison with glass fibre.
Saves time and money
The coefficient of thermal conductivity is extremely low and the material settles without sinking, even when the insulation layer is thick. – The special ISOCELL blowing system enables seamless insulation without waste.
Optimum sound insulation
Tests prove: ISOCELL cellulose insulation provides up to 7 dB more sound insulation than conventional fibre matting in partition walls.
Maximum resistance to fire
ISOCELL cellulose insulation has the ability to store moisture without loss of its insulating properties and to release it. This regulates the room climate in a natural manner and saves heating costs. When used in renovations or flat roof systems without rear ventilation ISOCELL acts from a structural point of view as a damp buffer. In addition, air and wind-tightness are considerably better particularly in wooden constructions, compared with conventional fibre matting.
ISOCELL cellulose insulation can be used in a variety of ways. For the insulation of sloping roofs, top floor ceilings and walls or as insulation for buffer tanks, installation shafts, vaulted ceilings e.g. in churches and as visible spray-on acoustic insulation.
ISOCELL cellulose works quite simply. The blowing expert comes to the construction site with his truck and brings everything he needs with him. Blowing machines and cellulose fibre. The building developer, carpenter or drywall builder has prepared everything in advance. The ISOCELL blowing machine stays on the truck and is filled with cellulose there. The expert positions the blowing hose in the correct positions and work begins. The cellulose fibres matt together in the construction and form seamless insulation matting. No matter whether floor, ceiling or wall – it is always the same product.
natureplus-certification for our cellulose
An award for our insulation material
It is 25 years since ISOCELL saw the light of day. A quarter of a century during which our vision of a sustainable, ecological insulation material has reached many people. Now our blown-in cellulose insulation has been certified by an independent committee to stringent natureplus criteria. This international seal of quality stands for excellent, sustainable products in the field of construction material and products for the home.
“When I insulate well the technology is not important.“
Kay Künzel is expert for green architecture
He counts on passive houses and energy-efficient construction and is an approved expert for acoustic and thermal protection. And: Kay Künzel cannot understand the culture of questioning “When does it pay off?“ with regard to house construction. “I don’t ask this question when I buy a pair of pants, either.“
A promise is a promise.
Responsible for blowing technology at ISOCELL is Herbert Kriechhammer. Besides blowing machines, a complete system is supplied. That makes total sense, but was not always so. “We started in 1996 and at that time there were hardly any machines on the market that were manufactured well, were quick and performance-oriented. Our partners‘ machines often did not function. And so we began to construct blowing machines ourselves.“
