Fixed Aluminium Louvres

Features

Overview

Fixed aluminium louvres are angled blades set at a permanent pitch within a frame, so they filter sightlines and block direct sun without moving. Knotwood fixed louvres come in 65mm and 88mm blade profiles with concealed fixings, and the angle is set at manufacture to suit the aspect, which means privacy and solar shading are engineered for the elevation rather than adjusted day to day.

Concealed Fixings

Once the slats are secured to the side frames, the Infill (KEIS) fits over the join to hide every fixing used to hold the Geometric Slat in place, leaving a clean, fastener-free face on the finished frame.

Inspiration

Blue Jay

On one of Burleigh’s most coveted streets, this modern coastal home layers Knotwood aluminium battens and tumbled silver travertine to create refined depth. White Ash battens unify screens, garage doors, ceilings and awnings, adding texture, privacy and sun protection, while seamlessly connecting interior and exterior living spaces.

FAQs

What is the difference between fixed aluminium louvres and operable louvres?

Fixed aluminium louvres have permanently angled blades with no moving parts, providing a consistent level of privacy, shade and airflow without any adjustment mechanism. Operable Louvres allow blade angle adjustment via a control bar. Fixed Louvres are simpler to install, require less maintenance, and suit projects where consistent shade direction and privacy are needed without daily adjustment.

What blade options are available for fixed aluminium louvres?

Knotwood fixed aluminium louvres are available with two blade types: the 65 x 16mm Geometric Slat and the 88mm Blade. Each blade type has its own routed frame system (65mm or 88mm frames), allowing panels to be specified to match the visual scale of the project. The 65mm slat gives a finer, more traditional louvre appearance, the 88mm blade provides a bolder, more contemporary aesthetic.

How is the blade angle set on fixed aluminium louvres?

The angle is worked out from the orientation of the elevation and the sun path for your location, then fixed at fabrication. On a west-facing facade the blades are typically set to block the low afternoon sun while still allowing a view out and light in at other times of day. On a privacy screen, the angle is set from the sightline you need to block and the position it is viewed from, rather than from the sun. Because the angle is permanent, it is worth resolving early: a fixed system that suits the elevation outperforms an operable one nobody adjusts. Send us your elevation, orientation and location and our technical team will recommend the blade and the angle.

Can fixed aluminium louvres be installed vertically and horizontally?

Both orientations are used. Horizontal blades are the more common arrangement on a facade, where the blade angle is set to intercept the sun at the height it matters. Vertical blades suit an elevation where the low morning or afternoon sun is the problem, or where the design calls for a vertical rhythm. The frame and infill system is the same in both cases. Send us your elevation and orientation and our technical team will confirm the setout and the blade angle to suit.

What structural standards apply to fixed aluminium louvres?

Fixed louvre systems are designed against the AS/NZS 1170 series for structural actions, including AS/NZS 1170.2 for wind actions, with AS/NZS 1664.1 for aluminium structures. Blade span, blade profile and frame sizing depend on the wind region and the opening, so the system is sized per project rather than supplied to a fixed maximum span. Send us your elevations and site address and our technical team will confirm the sizing.

Are fixed aluminium louvres non-combustible and suitable for bushfire zones?

Knotwood aluminium is not deemed combustible when tested to AS 1530.1, and achieves a Spread of Flame Index of 0 to AS/NZS 1530.3. The profiles also hold a Group Number 1 classification under AS 5637.1, the highest of the four classifications for wall and ceiling linings. Bushfire construction is assessed against AS 3959 using the Bushfire Attack Level for the site, and compliance is determined by the assembly rather than the material alone. Louvre systems have not been assessed as a standalone bushfire element, so send us your BAL rating and the application and our technical team will confirm what we can supply.

Are fixed aluminium louvres suitable for coastal properties?

Aluminium is corrosion resistant, which is why it is commonly specified near the coast where salt air accelerates the deterioration of steel and untreated timber. How a finish performs depends on how close the site is to breaking surf, the exposure of the elevation and the cleaning regime. Grade 316 stainless steel fasteners are required for marine zone installations. Send us your site location and we will confirm the right finish, the fixing specification and the maintenance schedule for that exposure.

How much do fixed aluminium louvres cost?

Knotwood does not publish fixed pricing, because louvre systems are quoted on specification. The main variables are the finish, the blade profile, the span and the frame the blades are fixed into. Blade angle and spacing also affect the blade count for a given opening, which changes the figure. Send us your elevations and we will quote it.

What finishes are available on fixed aluminium louvres?

Fixed Louvres are available in solid powder coated colours and in timber-look aluminium finishes, with a wood grain surface over a powder coated base. That is the same architectural-grade finish range used across the Knotwood product line, so louvres can be matched to cladding, screens or battens on the same project. The full range is on our finishes page.

How are fixed aluminium louvres assembled and installed?

Fixed aluminium louvres are assembled as a complete modular panel before installation. Blades are secured into left and right routed frames, a top and bottom frame is added, and an infill strip conceals all fixings to produce a clean, fastener-free face. The completed panel is then placed into the prepared structural opening. Because there are no moving parts, the assembly is simpler than an operable system and there is nothing to commission once it is in.

What warranty do Knotwood fixed louvres come with?

Knotwood fixed louvres carry a powder coat warranty to AS 3715, and the term depends on the finish you specify. Woodgrain finishes use Interpon D STF and carry up to 15 years. Standard colours carry 10 years on Interpon D1000, or 25 years on Interpon D2525, the ultra-durable coating used on prestigious commercial and high-rise projects. All warranties must be registered to take effect. Full terms and the registration form are on our warranty page.

What maintenance do fixed aluminium louvres need?

Periodic washing with a soft broom, water and a pH-neutral detergent is all that is required. Because the blades are fixed and there are no moving parts, there is no mechanism to service, lubricate or recommission. Rinse more often in coastal or industrial locations where salt and airborne deposits build up on the blade faces, and keep the frame drainage clear of leaf litter.
