FIW Munich

What FIW Munich does

FIW Munich (Forschungsinstitut für Wärmeschutz e.V. München) is a registered non-profit association founded in 1918 that operates Europe's largest testing facility for thermally insulating materials, headquartered in Gräfelfing near Munich with a branch in Vierkirchen. The institute delivers three interconnected service pillars: accredited Testing (mechanical, hygrothermal, and thermal property measurement across a -180°C to +900°C range for building and industrial insulation), Certification (customized schemes including the voluntary FIW Q-Zeichen, the European KEYMARK, and mandatory regulatory system certifications under DAkkS accreditation D-PL-14116-01-00 and D-ZE-14116-01-00), and applied Research (commissioned studies on thermal protection, energy efficiency, vacuum insulation panels, and policy evaluation including Germany's Federal Funding for Efficient Buildings). Approximately 80 specialized researchers, lab staff, and testing engineers deliver these services, with proprietary in-house instruments (Hot-Box-Rohr, Dilatometer, THEA) and active participation in CEN TC 88, DIN, VDI, and ASTM standardization committees.

Revenue is generated through three streams: commissioned testing and certification services for manufacturers, applied research contracts funded by federal ministries and energy agencies (BMWK, dena, UBA), and recurring membership fees paid by insulation industry members of the FIW e.V. association. The institute operates under a sales-led GTM motion anchored in DAkkS accreditation credibility, standardization-body influence, and annual industry events such as the FIW Forschungstag. Leadership comprises Institute Director Prof. Dr.-Ing. Andreas H. Holm (since 2011, also CEN TC 88 chairman) and Board Chairman Klaus W. Körner (25-year tenure, during which headcount and revenue doubled). Recent strategic activity — including Vierkirchen capacity expansion, REDcert² sustainability certification entry, and ongoing equipment modernization — indicates continued scaling within a niche but structurally protected market.

Core offering

FIW Munich operates an accredited testing laboratory, certification body, and research institute focused on thermal insulation materials for buildings and industrial applications. It conducts mechanical, hygrothermal, and thermal property testing between -180°C and +900°C, issues voluntary (Q-Zeichen, KEYMARK, REDcert²) and mandatory certification marks, and delivers applied research on thermal protection and energy efficiency. Services are delivered to insulation manufacturers, the construction industry, and public-sector clients across Germany and Europe.

Product overview

FIW München (Forschungsinstitut für Wärmeschutz e.V. München) is a research, testing, and certification institute for insulation materials, building products, components, and systems. Founded in 1918, it operates three core service pillars: Testing (Prüfstelle), Certification (Zertifizierung), and Research (Forschung). The Testing laboratory is the largest checkpoint for heat-insulating materials in Europe, covering mechanical, hygrothermal, and thermal properties testing. The Certification body offers customized certification schemes including the voluntary Q-Zeichen and KEYMARK, as well as mandatory system certifications. Research services encompass applied research on thermal protection, energy efficiency, and sustainability. These services are interconnected: testing provides the data foundation for certifications, while research advances methodologies and informs certification criteria development.
