3D CORE,lightweight components,honeycomb


Cross|CORE™ construction boards consist of a 3D|CORE™ foam core filled with an epoxy resin system to guarantee excellent strength, low weight and long-term dimensional stability. The surface layers made of fibres (e.g. GRP, CFRP, aramid) or HPL can then be coated and printed in a variety of ways. The construction boards can be individually assembled according to your wishes in terms of core thickness, surface layer and fire protection class. You then receive an ultra-lightweight, ready-to-install composite component, which can be delivered including inserts on request.

In order to completely save you the process of production, we supply the Cross|CORE™ construction boards not only as boards according to your drawing, but also as cuts accurate to the millimetre, including edge processing according to plan. Alternatively, our boards can also be finished using standard woodworking machines.

Due to the unique 3D|CORE™ structure, Cross|CORE™ construction boards have significantly better properties than other foam core composite boards or wood. For example, they are characterized by excellent weather and vermin resistance, high tolerance accuracy, good acoustic properties, excellent strength and high chemical resistance.
