What Arsanit does

Arsanit GmbH is a German manufacturer of building chemical products and thermal insulation systems headquartered in Nettersheim, Germany. The company produces expanded polystyrene (EPS) insulation boards, dry-mortar products (adhesives, tile adhesives, floor leveling compounds, reinforcement mortars), pastöse products (primers, decorative renders, facade paints), and waterproofing systems, all certified by the German Institute for Building Technology (DIBt) and the European Organisation for Technical Assessment (EOTA). Its flagship integrated offering is the Wärmedämmverbundsystem (WDVS), a thermal insulation composite system that combines EPS or mineral wool insulation boards with compatible adhesives, mortars, and renders from a single manufacturer.

The company operates four production facilities and employs over 200 people, with in-house R&D laboratories supporting continuous product development (evidenced by ten or more new SKU launches in 2025 alone, including the DLX MW mineral wool system and the Hydroisolator waterproofing line). Arsanit sells directly to construction companies, facade specialists, and building renovation professionals through a B2B model centered on website inquiries, phone consultations, and quote-based pricing, primarily serving the DACH region. The company is privately held with no disclosed external institutional investment, parent company, or public listing, and is led by Managing Director Slawomir Mordas-Zylinski.
