Construction Specialties (UK)

Designed to provide excellent protection against rain penetration and efficient airflow, CS Rain Defence Louvres are available in a wide variety of blade configurations. Options include models with varying blade depths or concealed behind attractive perforated screens to integrate seamlessly into any building façade.

The range features horizontal and vertical blade models, many of which offer additional features such as glazing frames for curtain walling applications and blast-resistant configurations. RC2 security-rated options are also available.

There are nine models in total, each with distinct performance and aesthetic qualities. All achieve Class A rain defence, with most maintaining this at core ventilation rates up to 3.5 m/s. For best combined airflow and rain protection, the RS-5605 model delivers Class A 1 performance up to 3.5 m/s, independently verified through testing in accordance with BS EN 13030:2001.

All models are modular and factory-fabricated for ease of installation. Standard visible mullions align with façade elements, while select models are available with invisible joint configuration.

A full range of accessories is also available, including bird guards, insect meshes, blanking panels, doors, and dampers.
