Construction Specialties (CS) has introduced AMCA‑certified architectural louvres to the European market, providing specifiers with access to reliable and independently verified performance data.
As an AMCA member, CS also participates in the AMCA Certified Ratings Programme (CRP). Under this programme, louvre performance is independently tested and subject to ongoing audits, helping to ensure that published data remains accurate over time. This sets it apart from other standards used to verify louvre performance, which typically result in a one-off test report.
AMCA certification complements the EN 13030 testing already carried out on CS louvres in Europe, adding a further layer of independent verification and ongoing validation.
A total of 15 AMCA‑certified louvre models are now available, including a selection of weather louvres designed to resist wind-driven rain ingress under demanding conditions, as well as several ventilation louvres engineered to maximise airflow performance where rain defence is not critical.
All models have been tested in accordance with ANSI/AMCA Standard 500‑L: Laboratory Methods of Testing Louvers for Rating, which defines how louvre performance is assessed under a range of airflow and environmental conditions. Testing covers key characteristics such as airflow performance, pressure drop, water penetration and wind-driven rain resistance.
In addition, two of CS’ rain defence models are now AMCA 550 Listed, demonstrating proven resistance to high-velocity wind-driven rain.
By combining independently verified data with ongoing compliance checks, AMCA certification supports more informed specification and greater confidence in performance throughout the building lifecycle, helping to ensure that louvre systems perform as expected in both testing and real-world conditions.
