What materials are architectural louvres made from?

Architectural louvres are manufactured from a range of materials, each selected for durability, performance characteristics, and suitability for the building’s environment. The most widely used material is extruded aluminium, chosen for its strength-to-weight ratio, corrosion resistance, and design flexibility. Aluminium is also well suited to bespoke extrusion, allowing complex blade geometries to be created through customised die tooling and multi-part profile assemblies.

Aluminium louvres can be finished in a variety of ways—including polyester powdercoating, anodising, and specialist architectural finishes such as sublimated timber effects, patinated finishes, and evolving surface treatments—providing long-term durability and aesthetic consistency across the façade.

In some applications, such as those within our Aquarius Guardian range, louvres may be manufactured from galvanised or stainless steel, particularly where increased structural strength, impact resistance, or enhanced security performance is required. For bespoke architectural screening, timber or even glass louvre blades may also be used, although these tend to require more ongoing maintenance and greater consideration given to robustness, than aluminium systems.

At Solinear, our Aquarius X-LINE architectural louvre systems are primarily engineered from high-grade aluminium alloys to deliver reliable airflow, effective weather protection, and long-term façade performance. We work closely with clients to select the most appropriate materials and finishes based on environmental exposure, acoustic or security requirements, and the project’s overall architectural intent.
