ETA certification: AF SEISMIC JOINT, fire protection for expansion joints with movement

We are pleased to inform you that AF Systems has obtained the ETA certification for AF SEISMIC JOINT, our solution for fire protection of expansion joints with movement.


AF SEISMIC JOINT is a mat easy to install, particularly suitable when large movements of the support are provided (wall/floor), as in the case of very high buildings or for application in areas with seismic risk. It can be applied to the floor intrados and extrados and secured with metal expansion plugs.


The fire resistance is EI 120 wall and floor according to EN 13501-2. The tests were carried out in accordance with EN 1366-4.

When exposed to a temperature above 180°C, the materials composing AF SEISMIC JOINT release water vapour due to their ablative capacity, lowering the temperature on the unexposed side.

The product is marketed in the following nominal sizes:


AF SEISMIC JOINT is certified with maximum permissible movement of +/-50% of the nominal width, for the coverage of joints with amplitude up to 600 mm, thus reaching a maximum extension of 900 mm.

AF SEISMIC JOINT meets the requirements of category Y1, having a certificate to be used at temperatures between -20° and 70°C, with exposure to ultraviolet rays and in environments with high humidity (max 85%).
