Tongue & Groove Cladding
This high-performance, complete timber cladding system helps you create durable, beautiful, long-lasting linear textures. It is suitable for both the interior and exterior of your building project, offering design continuity and performance across all environments.

How it works
Applicable for both interior and exterior applications, this system has been engineered to accommodate the natural movement of timber lining boards, ensuring structural reliability and a refined finish over time.
Timber naturally expands and contracts with seasonal temperature and humidity changes. This system is designed to move with the material, avoiding warping or surface inconsistencies over time.
Each board is installed using a self-drilling screw through the tongue, with the screw head concealed neatly by the groove of the next board. This results in a clean, uninterrupted surface with no visible fixings.
Combined with proprietary components and comprehensive installation details, Sculptform’s Tongue & Groove Cladding system offers an unmatched level of reliability and performance in all conditions.
A wide range of applications
Versatile and design-led, our Tongue & Groove Cladding system can be used across a range of architectural applications:
Interior applications
- Feature walls
- Acoustic panelling
- Tongue and groove wall panelling
Exterior applications
- Facades
- Screens
- Outdoor soffits and ceilings
Transitional spaces
- Soffit-to-ceiling transitions
- Indoor/outdoor continuity
- Entryways and eaves
Designing flowing interior volumes or bold external elevations calls for a solution that maintains visual and material continuity. Our system ensures coherence across all applications.

Suitable for Ceilings and Soffits
Our Tongue & Groove Cladding system is particularly well-suited for ceilings and soffits, offering seamless integration across internal and external zones.
Used as a tongue and groove ceiling, the concealed fixing method ensures a clean, uninterrupted visual plane. This makes it ideal for both residential living spaces and commercial entries, awnings or breezeways.
Soffits benefit from the same refined detailing, with profiles that can run continuously from inside to out, creating a cohesive flow that enhances architectural intent. The system can also accommodate integrated lighting or ventilation where required, maintaining the visual simplicity while meeting performance needs.
Timber Species and Coating Options
With a curated range of high-quality timber lining boards, Sculptform offers designers and specifiers a versatile palette of material choices. From native Australian hardwoods to thermally modified timbers, our selection supports a wide spectrum of project needs.
Each species can be finished with a selection of coatings that highlight the timber’s grain, tone and performance characteristics. These range from clear finishes to custom stains tailored for your project.
