Acoustics (EN 20140-3)  – 46 dB

Hinged metal door with pivoting functioning ensured by three exclusive hinges of this series. If desired,
the hinges can be concealed by extending the panel of the leaf, on all three sides in order to maintain
the symmetry of the door. May be equipped with a handle and anti-panic bar(s) or with a pair of handles.
The door closer may be apparent or hidden. The use of acoustic joints and an automatic seal in the lower
part of the leaf ensures a high sound attenuation that can reach higher levels if a sill is added.
