CS Architectural Louvres – Ventilation Louvres

Construction Specialties (UK)

Designed to maximise airflow performance, CS ventilation louvres are typically specified for areas where occasional rain penetration is acceptable, but cost-efficiency is a key consideration. These louvres offer high airflow capacity and low pressure drop, while still providing a degree of weather protection.

The range includes modular louvres, factory-fabricated for ease of installation – available in both visible- and hidden-mullion configurations - as well as continuous line systems, featuring blades designed to be clipped on-site into brackets pre-fitted to support mullions.

Seven ventilation models are available, each offering a unique combination of performance characteristics, physical properties, and visual appearance. This includes the PL-4080, which features a perforated sheet on the louvre face to provide a modern aesthetic, and the B-6485, a bespoke configuration solution.

The airflow and rain defence performance of CS ventilation louvres has been independently verified through third-party testing in accordance with BS EN 13030:2001.

CS also offers a comprehensive range of complementary louvre accessories, including bird guards, insect meshes, blanking panels, doors, and dampers.
