Isofran sandwich panels are composed of two precoated steel skins bonded with a three-dimensional composite core. The core is made of a knitted fabric impregnated with a thermoset resin. The stretchable fabric allows to mould very deep forms. Performances are controlled with the kind and the weight ratio of resin. Having two parallel planes, the core is easy to bond and permits to make flat or curved panels. Standard Isofran panels are 15 mm thick and maximum dimensions are 1.5 m for the width and 6 m for the length. They are used as cladding panels for buildings, especially for facades. The panel facade concept developed is very easy and fast to build. Functional analysis of cladding panels shows the following different steps: Architects or designers have to know all the data about the panels to take the working possibilities into account. Because o the big sizes of the panels they have not to be too heavy. Isofran panels weigh about 12 kg/m2. The building of the facade must be as easy and fast as possible in order to reduce its final cost. A galvanized steel secondary frame is built up and adjusted to ensure a good alignment of the panels. Then Isofran panels are assembled on the frame with screws and locked together with metallic parts. Panels are the skin of the building. Thus they must be resistant to weathering (temperature cycling between - 20 to 80 deg C, thermal shocks, dynamic pressure due to wind, rainfalls, aggressive atmospheres). Isofran panels are easy to clean and can be changed without any damage on the facade. The existing recycling process for steel based products is an advantage for Isofran panels.
