Solution

Top floor not accessible

Plank-lattice truss roof structures and unused attic space

 

Advantages

General advantages

  • top thermal insulation values
  • outstanding protection against heat
  • high sound insulation
  • high fire protection
  • ecological insulating material
  • adapts itself without wastage or joints to all undulations and gaps

The roof: Little effort - big effect

If the attic is not used as living space, then it collects quite a few treasures. However, there is no other part of the building where so much energy can be saved with so little effort as in the attic.The actual treasure of the house is proper thermal insulation!

Blow up - inaccessible areas

For the insulation of uneven surfaces with floor bracings (plank-lattice truss constructions), ISOCELL cellulose represents the only sensible solution from the point of view of building technology and economy.The loose material is conveyed from the truck up to the attic with the aid of the injection machine. After that an even, precisely fitting and jointless cellulose layer insulates the top floor and keeps the building warm in winter and cool in summer.

Insulation work in practice

  1. 01

    Preparation

    The injection specialist comes with his truck to the building site and bring along everything he needs: the injection machine and the cellulose.


  2. 02

    Fill the injection machine

    An assistant fills the injection machine on the truck with the ISOCELL cellulose insulation. Only the injection hose needs to be brought to the place of installation, not enormous amounts of material.


  3. 03

    Injection

    The injection specialist controls the injection machine on the truck by remote control.
    The top floor or attic is insulated in just a few hours.

Porr residental complex in rum

In nur acht Arbeitsstunden wurde die ­gesamte 315 m² große Flachdach­konstruktion des ehemaligen „Porr-Wohnheims“ mit 3,5 Tonnen Zellulosedämmstoff von ISOCELL gedämmt.
Eine Dämmung des Dachstuhls aus den 1970er Jahren wäre mit herkömmlichen Plattendämmstoffen aufgrund der beengten Platzverhältnisse nicht möglich gewesen.

Historic house in Bad Ischl

Die positiven Produkteigenschaften von ISOCELL Zellulosedämmung sowie der schonende Arbeitsvorgang kommen bei der Sanierung historischer Bausubstanzen ­besonders zum Tragen.
Der Einblasvorgang wird rationell und mit geringer Staubbelastung durchgeführt. Das Ergebnis ist eine fugenlose und wärmebrücken­freie Dämmmatte, die ­höchste Ansprüche an Energieeinsparung und Raumklima erfüllt.
