+44 (0)1296 652800 Website

Application

Suitable for applications where a continuous blade appearance is required across a facade and a high level of rain defence needs to be maintained.

Description

Double-bank architectural louvres with a continuous blade appearance across a facade, offering a high level of rain defence.

Features and benefits:

  • Front ventilation louvre, with a choice of 75 or 100 mm blade pitch for continuous blade appearance on the façade.
  • Choice of vertical blade rain defence units to the rear to provide excellent protection from wind-driven rain ingress.
  • The back modules are powder-coated black as standard to conceal their appearance.
  • Front blades are clipped on-site into the blade braces, which are pre-attached to the back modules.
  • Where only parts of the façade are functionally active and require rain defence solution, blanking panels are used behind the ventilation louvres in non-active zones, keeping costs down.
  • All double bank configurations have been tested for combined airflow performance.
