1. We make the supporting construction of partition wall, which we then attach to the floor, ceiling and walls and we connect the junctures with the washer tape.
2. On the both sides we fix cast-cardboard plates on the supporting construction.
3. On the upper part of the wall, right below the ceiling, we drill the holes into the cast-cardboard plates.
4. FonaTerm® - granular insulation is blown in through the holes with the special machine- on the pipe system to each compartment of the manufactured wall, in order to fill it with appropriate density, which is achieved with suitable ratio between the blowing in pressure and quantity of the in-blown material.
5. The drilled holes in cast-cardboard plates are closed and washed with washer tape.

Mansard partition wall insulated like this is insulated in one piece without thermal and sonic bridges, which is very efficient and significant for thermal and sonic insulation.
