The challenge
Concerned about the safety of the tunnel’s users, the Brussels-Capital Region has launched major renovation work and the creation of 17 new emergency exits in the
tunnel.
The installation of the tunnel doors had to be carried out under special conditions so as not to impede mobility: at night, between 10 p.m. and 6 a.m.; during school holidays.
The Heinen solution
The Heinen company has developed its range of HCM N3 single and double swing doors to comply with the increased hydrocarbon fire curve.
The road tunnel doors are HCM N3 compliant, fire resistant for 240 min, as well as complying with the emergency exit legislation.
