Access doors

BEIRENS access doors (600 x 1,200 mm) with natural ventilation allow inspection of the stack base and access to the internal ladder for Multi-flue and Double-wall chimneys. Natural ventilation of the structural shell ensures protection and safety of the maintenance staff.

BEIRENS also offers manholes for cleaning and inspecting the installation. Manholes, in compliance with regulations, must have a surface area of at least 0.28 m2 and a minimum width of 0.45 m.
