Operable Louvres

How do Knotwood Operable Louvres work?

Knotwood Operable Louvres use 88mm aluminium blades mounted in a framed system and linked by a control bar. Tilting the control bar simultaneously adjusts the angle of all blades, allowing you to control the amount of light, airflow, and privacy passing through the screen. The system can also be configured to slide, bi-fold, or hinge as a complete panel for full open or closed positions.

What is the difference between Knotwood Operable Louvres and Fixed Louvres?

Operable Louvres have adjustable blades that can be tilted, slid, or folded to vary airflow, light, and privacy on demand. Fixed Louvres have permanently set blades and cannot be adjusted once installed. Operable Louvres are the right choice where conditions change throughout the day or season; Fixed Louvres are better suited where a consistent, low-maintenance privacy and shade solution is preferred.

Can Knotwood Operable Louvres be installed vertically or horizontally?

Yes. Knotwood Operable Louvres can be installed in either vertical or horizontal orientation to suit the architectural intent and airflow requirements of the project. Horizontal installation is common for shade and sun control applications; vertical installation suits privacy screening on facades, balconies, and outdoor partitions. Orientation is confirmed during the design and specification stage.

Are Knotwood Operable Louvres BAL-40 rated for bushfire-prone areas?

Yes. Knotwood Operable Louvres are BAL-40 fire rated, meeting the requirements of AS/NZS 3959 for building construction in bush fire zones. The aluminium blade and frame system is non-combustible. For projects in bushfire-prone areas, confirm the full system specification including frame fixing method with Knotwood’s technical team to ensure whole-of-system compliance.

Can Knotwood Operable Louvres be motorised for remote operation?

Knotwood Operable Louvres are designed for manual operation via the control bar as standard. For motorisation options on larger or hard-to-reach installations, contact Knotwood’s technical team to discuss compatible motorised actuator solutions for your project. Motorisation is a common requirement on commercial facades and multi-residential balcony screens.

What does installing Knotwood Operable Louvres require in terms of structural preparation?

Operable Louvres require a pre-prepared structural opening or frame into which the louvre frame assembly is fixed. The louvre frame is assembled off-site or on-site and then fixed into the prepared opening using fixing plates or approved concealed fixing methods. This makes them more complex to install than batten screen systems and typically requires a qualified tradesperson.

How much airflow do Knotwood Operable Louvres provide compared to a fixed screen?

When fully open, Knotwood Operable Louvres allow maximum airflow through the opening, comparable to an unscreened aperture. When blades are tilted to a mid-position, airflow is partially restricted while privacy is maintained. When fully closed, airflow is significantly reduced. This active control over ventilation makes Operable Louvres particularly effective for outdoor living areas, pergolas, and balconies in Queensland’s humid climate.

What maintenance do Knotwood Operable Louvres require?

Maintenance involves periodic washing with water and a pH-neutral detergent. The pivot mechanism and control bar should be checked periodically to ensure blades rotate freely. The 88mm aluminium blade profiles and frame components are powder coated over a sublimated timber grain finish and do not require painting, oiling, or recoating. The system carries a 15-year limited warranty.
