ZAPP-ZIMMERMANN

What ZAPP-ZIMMERMANN does

ZAPP-ZIMMERMANN GmbH is a Cologne-based, privately held German specialty manufacturer founded in 1998 that develops and distributes intumescent fire protection products under the registered ZZ® brand. The company's core technology is intumescent material chemistry — formulations engineered to expand under heat exposure, with parameters such as expansion temperature, expansion rate, and char formation tuned to specific application requirements. Its commercial portfolio centers on S90-rated (90-minute fire resistance) combination fire seals (Kombiabschottung), specifically the ZZ® M30-S90 and ZZ® M21-S90 systems, alongside a system-component family including fire protection stones, foam, mortar, collars, bandages, joint seals, closure plugs, and repair seals.

The company holds multiple layers of regulatory approval, including German AbZ (Allgemeine bauaufsichtliche Zulassung), European ETZ/ETB assessments, Swiss VKF certification, and conformance to DIN 4102-9, EN 1366-3, DIN 18540, and ISO 11600, with ongoing external surveillance by MPA Stuttgart and MPA Braunschweig and TÜV Rheinland process certification. It serves two principal segments: Hochbau (building construction — primary) covering cable, pipe, and combined penetrations in residential and commercial buildings, and an industrial segment covering rail vehicles, tunnel construction, ventilation, sanitary/HVAC, electrical installations, and maritime applications. The company also acts as a B2B supplier of intumescent raw materials and fire protection powders for downstream industrial processing.

ZAPP-ZIMMERMANN operates a sales-led go-to-market model through a certified Fachhändler (specialist dealer) network within Germany, supplemented by technical-consultation presence on the baufragen.de expert platform and organic-social marketing across LinkedIn, Facebook, YouTube, and Xing. Specific pricing is not publicly disclosed and revenue figures are not reported; the entity is a privately held GmbH with no disclosed external investors or parent company.
