Curved sandwich-construction panels are produced and fixed to flat sandwich panels for use in caravans etc.; they utilise foam core material and the core can incorporate stiffening profiled sections. As a first operation a flat sandwich panel receives parallel saw cuts through the inner skin at the area to be bent, the panel is then bent, and finally fixed to the straight panel at the straight part adjacent to the bend. Suitable for roof or wall components, low cost, eliminate need for aluminium coverings for timber or metal members. |
