Overview

SDS Australia

Industry-Leading 50-Year Transferable Warranty

Accoya is backed by an unmatched 50-year above-ground warranty and a 25-year warranty in ground and fresh water applications. Unlike many building materials, this warranty is transferable to future property owners, helping protect the long-term value of your investment.

Architectural Colour. Engineered Into the Timber.

Manufactured using Accoya’s proprietary acetylation process, the timber is modified at a cellular level to dramatically reduce moisture absorption, helping resist swelling, shrinking, warping and decay. The result is exceptional dimensional stability and long-term performance, even in Australia’s most demanding environments.

Slate Grey Accoya Cladding combines the performance of Accoya with advanced colour technology, delivering a refined, consistent aesthetic without the need for ongoing coating.

Unlike painted or surface-treated timber, the colour is infused through the wood, creating a finish designed to age naturally without peeling, flaking or degrading.

Designed for contemporary residential, commercial and coastal applications, Slate Grey Accoya delivers premium aesthetics with significantly reduced maintenance requirements.

Important Information

Natural Variation — By Design

As a real timber product:

Tonal variation between boards is expected
Grain patterns remain visible
Subtle shifts in colour may occur over time

This is what gives Accoya its authentic architectural character.

Key Features

Architectural Colour Built Into the Timber

Slate Grey Accoya features advanced through-colour technology, where a non-toxic pigment is infused throughout the timber rather than applied to the surface. This means:

Cuts and exposed edges retain the same consistent grey appearance
Colour cannot peel, flake or wear away like conventional coatings
Minimal maintenance is required to preserve the architectural aesthetic
Natural grain patterns remain visible, preserving the character of real timber

Exceptional Dimensional Stability

Accoya’s acetylation process dramatically reduces moisture-related movement, helping minimise warping, cupping and swelling while maintaining clean architectural lines.

Low-Maintenance Performance

Unlike conventional exterior timbers, Slate Grey Accoya requires minimal upkeep. The integrated colour technology eliminates concerns about peeling or flaking finishes, while the timber’s stability helps coatings perform exceptionally well when used.

Sustainable & Non-Toxic

Manufactured from FSC® certified timber and coloured using a non-toxic pigment, Slate Grey Accoya is fully recyclable and supports environmentally responsible building practices.

More Controlled Aesthetic

Compared to natural weathering, Slate Grey provides a more uniform, architectural finish while still retaining the character of real timber.

Resistant to Rot, Fungi & Termites

Accoya’s modified wood structure provides exceptional resistance to biological degradation without relying on toxic preservatives, helping deliver long-term durability in demanding environments.
