Facade

Facade insulation of a solid construction
Plastered or suspended facades

 

Advantages

General advantages

  • energy savings of up to 40 %
  • diffusion-open and capillary
  • many different facade design options
  • high fire protection
  • dry masonry
  • outstanding protection against heat
  • high sound insulation
  • construction materials from renewable resources

Installation procedure

  1. 01

    Installation procedure

    Depending on the thickness of the insulation, timber laths, TJI beams or timber constructions are fastened to the solid wall. The centre-centre distance depends on the requirements of the respectively employed plaster base material.


  2. 02

    Window and door soffits

    Window and door soffits must be closed all round. Hollow spaces of less than 10 cm are stuffed by hand.


  3. 03

    Plaster base

    The respective plaster base material is mounted on the perpendicularly aligned spacers. In the case of rear-ventilated facades, a diffusion-open wood-based panel is attached.


  4. 04

    Preparation injection

    Holes are drilled into the hollow spaces for the injection hose shortly before installing the ISOCELL cellulose insulation.


  5. 05

    Injection

    The injection specialist comes with his truck to the building site and bring along eve-rything he needs: the injection machine and the material. Only the injection hose needs to be brought to the place of installation, not enormous amounts of material.
    By means of radio control the injection spe-cialist controls the injection machine on the truck, which an assistant fills with cellulose. The hollow spaces are insulated without joints and settlement-free in just a few hours.

Construction of new detached house in Eugendorf

In the construction of the new detached house it was not only the outstanding insulating characte-ristics that were particularly important to the young family man, but also safety in the event of fire.
ISOCELL cellulose insulation is classified under fire class B-s2,d0 – which means that it is flame resis-tant, unlike EPS insulating materials.
In addition, the sound insulation is significantly better.

Thermal renovation of house in Mattsee

In the thermal renovation of the detached house, the roof and the facade were insu-lated in addition to installing new windows.
“I wanted to offer the hard-working ISOCELL instal-lers a cake in the afternoon, but the facade was finished so quickly that they were already done and on the way to the next building site”, said the house owner. 
The U-value of the house was about 0.8 W/m²K before the renovation, now it is 0.15 W/m²K.
