Element Filling Systems
The field of element fillings systems allows several blow-in methods. When elements are blown in manually the main tasks are based on dense blowing with or without ventilation. The main injection tools are injection lances with ventilation, straight insulating needles, ventilated rotary nozzles or also just injection hoses. Injection lances are used for long closed elements. The insulation material is redensified by pushing with the lance while blowing injection.
Fully automated element filling systems are often used for the filling or open wall and roof elements on transport tables. For this case an insulation blowing plate is used in which multiple injection tools can be installed. The insulation blowing plate seals to the element with its own weight and a sealing appliance while injection blowing. The elements are closed after the blow-in process with board material.
Typical blowing insulation materials
- Wood fibre
- Glass wool
- Rock wool
