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
-
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.
-
02
Fill blowing 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.
-
03
Inject
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
The entire 315 m² flat roof construction of the former Porr residential complex was insulated with 3.5 tonnes of ISOCELL cellulose insulating material in just eight working hours. The insulation of the roof construction dating from the 1970s would not have been possible with conventional board insulating materials due to the cramped spatial conditions.
Historic house in Bad Ischl
The positive product properties of ISOCELL cellulose insulation as well as the gentle work process really come in to their own when renovating historical buildings. The injection process is accomplished rationally and with low dust levels. The result is a jointless insulating mat with no thermal bridges that meets the highest energy saving and room climate demands.
