Expanded polystyrene is passed through an electrically driven adhesive spreader. The PVA adhesive used is water based and solvent free.
The expanded polystyrene is laid on to a sheet of oriented strand board (OSB) using a lay-up table system. A second sheet of OSB is applied to form the structural sandwich. This sandwich then continues into a pneumatic laminating press by means of electric motors.
The panels are pressed for a specified time under a specified pressure to ensure satisfactory bond results. All materials are ordered to size to eliminate waste during the pressing process.
The entire process is controlled in accordance with ISO9001 – Quality Management Systems procedures and all operators are trained.
