The ever-growing demand for insulated panels in building applications is driven by the new energy-saving regulations imposing significant reductions on power consumption, that can be achieved by the thermal insulating properties of the materials used.
Sandwich insulated panels can be produced with a maximum thickness of 250 mm and either flexible (paper, cardboard and felt, centesimal aluminium sheet, etc.) or rigid facing (metal sheet, GRP, etc.) and using different types of insulating materials:
Polyurethanes
PIR
Phenolic resins
Dedicated presses and foaming plants for the manufacture of curved panels are also available.
1) DECOILERS FOR METAL SHEET
Unwinding group is usually composed of two decoilers, one for the upper profile and one for the bottom profile or more equipped with an automatic loading and positioning system of the coil on the relevant mandrel.
2) UPPER AND LOWER ROLL FORMING
Line for wall profile complete with micro ribbing device. Roof Panels require deeper ribs and a dedicated set of forming rolls for the external sheet layer. The system is designed for fast replacement of the forming rolls(cassette system).
3) ULTRAMIX-PLUS HIGH PRESSURE MACHINE
A high-Pressure multi-component dosing unit(number of components according to chemical formulations) equipped with mass flow transducers. If required hydrocarbons can be used as blowing agent and dosing unit.
4) CENTRAL SECTION
Pre Heating Unit:
Formed layers are heated to achieve good foam adhesion and the final quality of the sandwich
Foaming Portal (laydown):
Used to apply the reactive mixture via the mix head to the bottom facing, at Double Belt entrance.
