ZAPP-ZIMMERMANN has been offering innovative fire safety systems for more than 25 years, specialising in the areas of cable, pipe and combination penetration seals, as well as fire safety joint seals.
In addition to our proven product line of intumescent moulded parts made of PU penetration seal foam, we also offer other construction materials, such as silicone and acrylic for civil engineering, tunnel construction, shipbuilding, and rail vehicles.
In the course of harmonising fire safety in Europe, ZAPP-ZIMMERMANN GmbH tests its fire safety systems in accordance with the European test conditions to obtain a European Technical Approval.
5 years ago ZAPP-ZIMMERMANN started to test the successful firestop products according to the American standards ASTM E814 (UL 1479) to obtain UL classified firestop systems.
