Timberceiling
Solid timber ceiling systems engineered for stable, lightweight, and long-lasting overhead surfaces in tropical environments.
What Is Timberceiling?
The Stability of Accoya.
The Simplicity of a Panel.
Timberceiling is a solid Accoya ceiling system engineered for tropical performance across interior and protected exterior applications.
Dimensionally aligned with Timberclad but reduced to a 4 mm profile, Timberceiling delivers clean, stable, and lightweight ceiling planes without the risk of warping, sagging, or telegraphing over time.
Installed using a concealed, panel-style fixing system, it combines the visual continuity of a panel with the durability and dimensional stability of exterior-grade modified timber.

Applications
Interior Ceilings
Creates warm, continuous ceiling planes with exceptional dimensional stability. Used in residential, hospitality, and commercial interiors where long-term flatness and clean detailing are required.
Covered Outdoor Ceilings
Installed in roofed exterior areas such as verandas, terraces, and canopies. Accoya’s modified timber performance supports use in humid, semi-exposed conditions without distortion.
Feature Ceilings
Defines key spaces through texture, rhythm, and material presence. Applied in lobbies, lounges, dining areas, and circulation zones to create architectural focus overhead.
Linear & Panelised Ceiling Systems
Supports battened, slatted, or panelised ceiling layouts. Suitable for modular ceiling designs requiring precision alignment and visual consistency across large areas.
Why Timberceiling Delivers Clean Lines That Stay Clean
Exterior-Ready Durability
Engineered for long-life performance in protected exterior soffits and verandas, offering Class 1 durability and resistance to tropical humidity.
Ultra-Stable for Flawless Lines
Solid Accoya provides industry-leading dimensional stability, preventing warping, sagging, or telegraphing for consistently flat ceiling surfaces.
Panel-Fast, Clean Installation
Designed for concealed clip installation with precise alignment, enabling fast, repeatable installation and seamless ceiling planes without visible fixings.
Lightweight & Low Maintenance
The 4 mm profile reduces structural load and installation effort while maintaining durability, helping minimise long-term maintenance demands.

Performance Characteristics
Dimensional Stability
Very High
Accoya offers industry-leading stability, maintaining clean ceiling lines over time with minimal movement.
Moisture Content
4 – 6% (Accoya equilibrium)
Kiln-conditioned to equilibrium for stability during and after installation.
Moisture Movement
Very Low
Minimises expansion and contraction, reducing stress on joints, fixings, and finishes.
Thermal Performance
Low Conductivity
Contributes to comfortable surface temperatures and improved interior comfort.
Seismic Suitability
high
Lightweight ceiling system reduces mass and associated seismic loads.
Acoustic Behaviour
Diffusive
Timber surfaces help soften echo and reverberation; final acoustic performance depends on the full ceiling assembly.
Is Timberceiling Right for Your Project?
Timberceiling is not a decorative veneer or composite panel. It is a solid timber ceiling system engineered for stability and longevity.
It is most effective when:
-
ceiling flatness and alignment matter visually
-
humidity or seasonal change is expected
-
lightweight construction is preferred overhead
-
exterior soffits require durable timber solutions
If your project requires clean, stable ceiling planes that perform predictably in tropical conditions, Timberceiling should be specified early.
Frequently Asked Questions
Got a question unanswered? Speak to our team.
Can Timberceiling be used outdoors?
Yes, in protected exterior applications such as soffits, verandas, and roofed outdoor areas. It is not intended for direct weather exposure.
Is Timberceiling suitable for humid interiors?
Yes. Accoya’s modified structure delivers exceptional dimensional stability, making Timberceiling suitable for humid interior environments when installed correctly.
Can individual panels be replaced?
Yes. The concealed fixing system allows individual boards to be removed and replaced without dismantling the entire ceiling.
