Innovative Design for Faster, Smarter Installation

This advanced tongue and groove system has been carefully engineered for precision and performance. The tapered tongue creates a self-aligning fit that speeds up installation and ensures consistent spacing, while the concealed screw line allows fixings to be driven through the tongue and hidden by the next board.

A pre-set expansion gap built into the tongue accommodates the natural seasonal movement of solid oak, maintaining a stable, uniform surface even in changing weather conditions. The result is a refined cladding system that combines cutting-edge machining with the timeless appeal of real oak.

Built for Strength and Long-Term Durability

European oak’s natural density and toughness make it one of the most reliable hardwoods for exterior use. It offers excellent resistance to moisture, decay, and wear — qualities that make it a favourite among architects, builders, and designers.

When used outdoors, the oak will gradually develop a silver-grey patina, adding natural elegance to any façade. Indoors, it retains its golden tone and pronounced grain, creating a warm, organic finish ideal for feature walls and ceiling panelling.

Clean Lines and Contemporary Style

The hidden fix design allows every board to sit flush, creating smooth, continuous lines without visible screws or nail heads. This detail gives modern buildings, garden rooms, and extensions a refined architectural appearance, while maintaining the tactile authenticity of solid oak.

Whether used horizontally or vertically, the precise tongue and groove joint keeps alignment perfect across every board, delivering a professional finish that enhances both traditional and contemporary designs.

Environmentally Responsible and Sustainable

All timber used in our Solid Oak Hidden Fix Cladding is sourced from sustainably managed European forests. Choosing oak means choosing a renewable material with a low environmental footprint — a natural, long-lasting alternative to plastic or composite cladding systems.

Each board is manufactured in the UK using responsible processes that reduce waste and maximise yield, ensuring the highest quality and environmental integrity.

The Smarter Choice for Modern Cladding

Our Hidden Fix Oak Cladding combines modern engineering with the enduring performance of solid hardwood. Its tapered tongue and groove and concealed screw line make installation quick, secure, and visually seamless — delivering a premium finish built to stand the test of time.

Whether you’re upgrading an exterior façade, designing a garden studio, or creating a minimalist interior feature, this cladding provides a perfect blend of natural style, strength, and innovation.
