What Alumat Frey does

ALUMAT-Frey GmbH, founded in 1980 and headquartered in Kaufbeuren, Germany, develops and supplies barrier-free magnetic zero-threshold systems and sealing solutions for exterior and interior doors and windows. The company's core technology is a patented Magnet-Doppeldichtung (magnetic double-seal) system in which permanent magnets engage the upper seal position when the door is closed—providing driving-rain, sound, smoke, and airtight performance—while dropping down to allow a flush, wheelchair-accessible transition when the door is open. Product families include the MFAT PH passive-house-certified line (world-first Passivhaus-certified zero threshold, Effizienzklasse phC), the MFZ renovation profile line, the MHT magnetic comfort threshold for entry doors, the HST lift-and-slide door flat-threshold line, and the newly introduced MPI 10 / API pivot-door systems, complemented by accessories such as structural sealings (Bauwerksabdichtung), interior-door magnetic seals, aluminium door-stop rails, and weatherstripping.

The business operates on a B2B hardware-sales model, selling components to window and door manufacturers (wood, PVC, aluminium), specialized trade partners (Fachhandel), construction companies, and—via specification—architects and planners. Distribution is executed through a Vertriebsnetz across Germany, Austria, Switzerland, China, and Taiwan, supported by an online ordering/inquiry service, a registered business partner portal with CAD details, and software integration via Orgadata's LogiKal platform. A February 2025 strategic partnership with profine Group makes ALUMAT thresholds configurable and orderable through profine's PVC door systems. The company markets through its multilingual website, trade fairs (notably Fensterbau Frontale), LinkedIn/Facebook presence, technical documentation, and earned media in industry publications. Recognitions include German Design Award Gold 2020, Universal Design Awards (2013, 2022), and Hessischer Staatspreis Universelles Design 2022, alongside DIN 18040 and CEplus compliance; a 20-year warranty on magnetic force underpins the durability claim. The company is led by Managing Director Claudia Rager-Frey and operates as an independent, privately held GmbH with 11–50 employees and no disclosed external funding.
