Ventilation systems

Ventilation grille
Brand Betonbau

Ensuring ventilation, but effectively denying access to snow, rain, insects and unauthorised intruders - Betonbau ventilation grilles solve this demanding task in a particularly intelligent way. For example, by means of aluminium louvres, highly effective perforated plates or a range of special solutions for very specific requirements. Poke-proof ventilation prevents condensation and ensures the dissipation of transformer heat loss. The individual elements can be flexibly adapted to the structural conditions and are suitable for installation in both doors and walls.

  • Aluminium ventilators in 50 or 100 mm depth versions
  • Ventilation domes for all-round continuous ventilation
  • Ventilation domes: for ventilation above the roof, for sophisticated ventilation systems or optional, if there is no space in the building itself for the installation of a ventilation in the wall.
