Construction Specialties (CS) is pleased to introduce AMCA‑certified architectural louvres to the European market, providing specifiers with access to reliable, independently verified performance data.
As an AMCA member, we also participate in the AMCA Certified Ratings Program (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 AMCA certification apart from other approaches to louvre testing, which typically rely on a one‑off test report.
AMCA certification complements the EN 13030 testing already carried out on our louvres in Europe, adding a further layer of verification and ongoing validation.
We now offer 15 AMCA‑certified louvre models, including a selection of weather louvres designed to resist wind‑driven rain under demanding conditions, as well as several ventilation louvres engineered to maximise airflow where rain defence is less critical.

All AMCA‑certified models have been tested in accordance with ANSI/AMCA Standard 500‑L: Laboratory Methods of Testing Louvers for Rating, covering key performance characteristics such as airflow performance, pressure drop, water penetration and wind‑driven rain resistance.
In addition, two of our 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.
