Basic Classification of Louvres

Modern aluminium window louvres installed on a residential building by A TO Z FABRICATION PVT LTD in Guildford NSW.

Fixed (Stationary) Louvres

Fixed louvres are the simplest and most common type. As the name suggests, their blades remain stationary at a set angle, allowing constant airflow while providing privacy and weather protection. These are often used in building louvres for façades, ventilation shafts, and equipment enclosures where minimal maintenance is key.

Typical Applications:

  • External walls and façades
  • Parking ventilation areas
  • Generator and HVAC enclosures

Adjustable (Operable) Louvres

Adjustable or operable louvres allow the user to change the blade angle manually or automatically, controlling sunlight and airflow as needed. They’re ideal for louvre windows and louvre doors, providing flexibility and comfort indoors.

Best Used In:

  • Office and residential buildings
  • Pergola roofs and sun-shading systems
  • Commercial façades requiring adaptive shading

Drainable vs Non-Drainable Louvres

Drainable louvres come with built-in channels that collect and redirect rainwater away from the interior. These are vital for areas exposed to heavy rainfall. Non-drainable options, on the other hand, are cost-effective and suitable for drier climates or interior spaces.

By Orientation: Horizontal vs Vertical Louvres

Orientation changes everything. Horizontal louvres are typically used for overhead sun control, while vertical louvres are better for façade shading where the sun moves across the horizon. Both orientations influence not just performance but also a building’s visual character.

Functional Types of Louvres Based on Purpose

Ventilation Louvres

These are the workhorses of the HVAC world. Ventilation louvres allow air to flow freely while blocking rain and debris. They enhance air circulation in plant rooms, parking basements, and mechanical systems keeping the environment fresh and functional.

Sun-Shading Louvres | Solar Control Systems

Sun-shading louvres are designed to reduce glare and heat gain while maximizing natural light. Whether on windows, pergolas, or façades, they improve energy efficiency by reducing the need for artificial cooling and lighting making them a smart addition to any building louvre system.

Acoustic Louvres

Noise pollution is a growing concern in urban environments. Acoustic louvres are engineered with internal sound-absorbing materials that reduce noise levels while maintaining ventilation. They are essential in industrial or mechanical settings where both airflow and sound reduction are required.

Storm-Resistant | Weather Louvres

Built to withstand harsh conditions, storm-resistant louvres protect buildings from heavy rain, strong winds, and flying debris. Their design helps maintain interior comfort while preventing water infiltration a must for coastal or storm-prone areas.

Sand-Trap | Dust-Filtering Louvres

In arid or dusty environments, these louvres trap sand and dust particles, ensuring that clean air enters HVAC systems or sensitive interiors. They’re especially beneficial for facilities located in desert or industrial zones.

Hidden | Architectural Louvres

Architectural or hidden louvres merge functionality with design. They blend seamlessly into a building façade or become an intentional visual feature. With creative designs and finishes, they enhance both performance and architectural appeal.

Material & Profile Variations | What That Means for the Building

Materials Used (Aluminium, Steel)

Material choice affects everything durability, appearance, and cost. Aluminium louvres are the most popular due to their corrosion resistance, lightweight, and modern finish. Steel offers greater strength but requires more maintenance.
