For the injection of loose insulating material into building elements in the factory, either stationary or mobile machines may be used. Depending on the volume of insulating material which is processed daily, the filling of building elements in the factory brings with it certain advantages:
- Higher throughput volumes due to the application of machines which are tailormade for the situation and the use
- Better monitoring with online quality control instruments which measure directly after insulating material has been applied
- Wage cost is significantly lower than when insulating material with fixed forms (such as matting) is fitted manually
- Wage cost is lowered due to the use of bales and, in sections, automatic supply systems (one-man operated filling equipment)
Stationary equipment can be dismantled into sub-sections, which can later be extended again when the need arises. The essential elements to be found in the basic module are:
- Blow-in machine
- Tools for filling
Apart from these elements, the machine can be extended with the following components:
- Bales supply and emptying unit
- Online mass flow rate measuring equipment for accurate quality control
- Built-in controls
Stationary equipment needs individual planning. That requires the following information:
- Number and form of the building elements to be filled
- Space requirements of the filling station and the position of the blow-in machine with its supply system in the filling station (floor plan of production system)
- Indication of where the supplied bundles are positioned in the filling station
