Are Knotwood Fixed Louvres suitable for coastal properties exposed to salt air?

Yes. Fixed Louvres are explicitly designed to perform in coastal and harsh environments and are one of the few Knotwood screening products to carry this as a stated feature. The 6060 T5 aluminium alloy combined with a powder coat finish provides strong resistance to salt air corrosion. Grade 316 stainless steel fasteners are recommended for marine zone installations.

Can Knotwood Fixed Louvres be powder coated in solid colours rather than a timber grain finish?

Yes. Fixed Louvres are available in both traditional solid powder coated colours and the sublimated timber grain surface finish. This makes them one of the few Knotwood Screens products where a solid colour is an explicit finish option, giving architects and specifiers greater flexibility to match contemporary or minimalist design palettes that do not require a timber aesthetic.

Are Knotwood Fixed Louvres BAL-40 rated for bushfire zones?

Yes. Fixed Louvres are tested to AS/NZS 3959 (BAL-40) and combustibility standards AS/NZS 1530.1 and AS/NZS 1530.3. The non-combustible aluminium construction makes them a compliant choice for residential and commercial builds in designated bushfire-prone areas across Australia.

Can Knotwood Fixed Louvres be installed both vertically and horizontally?

Yes. Fixed Louvres can be installed in either vertical or horizontal orientation. Horizontal blade orientation is traditional for sun shading and rain deflection; vertical orientation suits facade privacy screening and contemporary architectural applications. The complete modular panel system is assembled and then placed into the prepared structural opening, giving flexibility in orientation during design.

How are Knotwood Fixed Louvres assembled and installed?

Fixed 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 finish. The completed panel is then placed into the prepared structural opening. The four-step process is simpler and faster than the Operable Louvre system, which requires seven steps.

What is the lifespan and maintenance requirement for Knotwood Fixed Louvres?

Knotwood Fixed Louvres carry a 15-year limited warranty and are made from 100% recyclable 6060 T5 aluminium alloy. With no moving parts, maintenance is minimal: periodic washing with a soft broom, water, and a pH-neutral detergent. There is no lubrication, adjustment, or recoating required at any point during the product’s service life.

Q: What blade options are available for Knotwood Fixed Louvres?

Knotwood Fixed Louvres are available with two blade types: the 65x16mm 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.

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

Fixed 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 are the better choice where consistent shade direction and privacy are required without the need for daily adjustment.

Fixed Aluminium Louvres

Features

Overview

Fixed aluminium louvres are a set-and-forget system: the blade angle is fixed in place, engineered to deliver permanent privacy and solar shading exactly where a project needs it, with nothing to adjust and nothing to maintain beyond the system’s natural low upkeep. For screens where the requirement doesn’t change through the day or the season, that simplicity is the whole point.

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.

FAQs

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.

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.

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.

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.

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

Fixed Louvres are manufactured from extruded aluminium, which is non-combustible, and are tested to AS 1530.1 and AS/NZS 1530.3 for combustibility and early fire hazard properties. Bushfire construction is assessed against AS 3959 using the Bushfire Attack Level for your site, and compliance is determined by the assembly rather than the material alone. Send us your BAL rating and the application details and our technical team will confirm what we can supply.

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.

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 maintenance do fixed aluminium louvres need?

Backed by a standard 15 year warranty and up to 25 years on selected finishes. See our warranty page for the terms that apply to this profile.

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.
