INSULATING CONCRETE WALLS WITH THE PERMANENT FORMWORK SYSTEM

The system consists in building bearing walls with concrete castings inside two parallel Celenit panels made from mineralised fir wood-wool bound with Portland cement. The panels are then fixed as appropriate (using large formworks, spacers or brackets). 
In this way, the insulation panels are incorporated in the casting, forming a single monolithic block. In this, the concrete nucleus, cast simultaneously along all the longitudinal and partition walls, determines the box effect characterised by high levels of rigidity and lateral stability.
This system can play a leading role in seismic zones.

  The system has the following advantages:

  • quick and economic construction;

  • thermal inertia;

  • the desired level of thermal insulation, by using Celenit panels of appropriate thickness and type;

  • up to a 30% improvement in the compression resistance and elasticity coefficient of concrete;

  • a significant recovery of useful space, through reduced wall width;

  • acoustic insulation also from external noises;

  • resistance, even without plaster, against severe weather conditions, such as beating rain, freezing temperatures and sun radiation;

  • fire resistance;

  • elimination of thermal/acoustic bridges, always important in concrete buildings;

  • elimination of condensates and relating damage to structures and systems;

  • excellent surface for any type of plaster.
