V Line Aluminium Cladding Boards

Features

Overview

V Line aluminium cladding boards are a flat board with a V-shaped groove running along each join, giving a facade a sharp, contemporary line without heavy texture. Knotwood’s V Line sits between the simplicity of a flush finish and the bolder depth of a dimensional or castellated profile. Available in two sizes, so the same profile can suit a feature area or a full elevation.

Vertical Install

V Line Boards install vertically using the same interlocking system as a horizontal run, each board clicking into the one beside it and fixed with concealed screws into the substructure. Installation follows a left-to-right sequence, working the same finishing trims, corners and starter used on a horizontal wall.

FAQs

What are V Line aluminium cladding boards?

V Line cladding is a cladding profile where a V-shaped groove runs along each board, creating a defined line of depth across the facade. Knotwood’s V Line Boards deliver this in aluminium: each board carries a distinctive V-groove that adds genuine architectural depth to the surface, more visual interest than a flat board while remaining more restrained than a castellated or dimensional profile.

How does V Line cladding differ from other cladding profiles?

V Line Boards sit in the middle of Knotwood’s cladding range. They have more depth and visual interest than a flush or shadow line board, but they are less bold than castellated or dimensional profiles. The V-groove runs along the board face rather than creating a shadow reveal between boards, giving the individual board itself an architectural character that a flatter profile does not have. This makes it a strong choice for facades that want a premium, considered finish without heavy texture.

What are the dimensions of V Line aluminium cladding boards?

V Line Boards come in two board widths: 100mm and 150mm. Boards are supplied in 6500mm lengths and install with a V-shaped interlocking groove. A ventilated option is available where airflow behind the facade matters, and the 100mm board can flex around curved surfaces.

Are V Line aluminium cladding boards non-combustible?

Yes. Knotwood aluminium cladding profiles, including V Line, are non-combustible. V Line is tested to AS 1530.1 and AS/NZS 1530.3 for combustibility and early fire hazard properties, and carries a Group One classification under AS 5637.1. Group Numbers are what the National Construction Code uses to set where a lining material can be used. For projects with formal compliance requirements, send us your building class and we will confirm the documentation for your project.

What warranty does Knotwood V Line cladding come with?

Knotwood cladding carries a standard 15 year warranty, with up to 25 years on selected finishes. The term that applies depends on the finish specified, and the full terms and conditions are set out on our warranty page. If you need warranty documentation for a submission or for a client, send us the request and we will supply it.

How much does V Line cladding cost?

Knotwood does not publish fixed pricing, because cladding is quoted on specification. The main variables are the board size, the finish, the total area and the trims the detail requires. V Line uses the same starters, corners and cover trims as the wider cladding range, and those matter to the final figure as much as the boards do. Send us your elevations and we will quote it.

What finishes are available for V Line aluminium cladding boards?

V Line Boards are available in traditional solid powder coated colours and in a sublimated timber grain surface, the same architectural-grade finish range used across the Knotwood cladding system. That means V Line can be specified alongside Shadow Line or any other Knotwood profile on the same facade with a consistent finish. The full range is on our finishes page.

Can V line cladding be used alongside other Knotwood profiles?

Yes. V Line Boards are designed to work alongside other Knotwood cladding profiles on the same project. A common approach is to use V Line on a feature section or facade panel and pair it with a flatter profile, such as Shadow Line, on the broader run. Because all Knotwood cladding shares the same fixing system, concealed fittings and finish range, profiles can be combined without sourcing from different suppliers.

Are V Line aluminium cladding boards low maintenance?

Yes. As an aluminium cladding system, Knotwood V Line aluminium cladding boards do not rot, split, cup or require the painting and sanding cycle that timber boards demand. Periodic washing with a soft broom, water and a pH neutral detergent is all that is needed, and more often on coastal installations to clear salt deposits before they sit on the finish. Avoid abrasive pads and solvent-based cleaners, since those can mark the powder coat.Finish warranty terms are set out on our warranty page.

What is V Line cladding suited to?

V Line Boards suit premium residential and commercial facades where the groove line adds depth without a heavy or highly textured look. They work well as a feature section paired with a flatter profile elsewhere on the same building, as the primary finish on a facade that needs visual interest at close range, and on architect-led projects where material character matters as part of the design brief.
