Efectis firetest
Efectis (formerly TNO) has tested this newly developed fire-resistant overhead door and has assigned the NEN-EN 1634-1 and also the classification NEN-EN 13501-2 to Protec for this innovative overhead door. This firedoor has even brilliantly achieved the classification EI1-60, the highest thermal insulation requirement. If desired, the fire-resistant overhead door can be designed with an integrated liquid-retention barrier, without this being disadvantageous to the fire resistance.
