Aestuver® fire protection boards for fire protection
Aestuver® is a German brand belonging to the Fermacell / Xella Group, specializing in lightweight cement-based fire protection boards and systems. With over 30 years of proven performance in some of Europe’s most demanding construction and infrastructure projects, it is recognized as one of the most reliable solutions on the market.
The boards are cement-bonded, glass-fiber reinforced lightweight cement panels that meet A1 non-combustibility classification requirements (non-combustible) and are suitable for use in EI/EW-classified structural fire protection systems. Aestuver withstands heat, humidity, frost, and mechanical stress, maintaining structural integrity during fire exposure without releasing toxic emissions.
The product range is divided into three application segments.
