Iroko Shadow Gap 120mm x 19mm Cladding

Iroko Shadow Gap 120mm x 19mm Cladding

Bring rich colour and contemporary detail to your exterior with our Iroko Shadow Gap Cladding, 120mm x 19mm. Machined in-house at our Devon workshop, these smooth-planed hardwood boards combine natural golden-brown tones with recessed joints for a clean, defined finish.

Ideal for garden rooms, extensions, porches, garages and exterior walls, Iroko’s distinctive grain adds warmth and character to both modern and traditional buildings.

Shadow Gap Profile with Secret Fixing

The profiled edges create a recessed shadow line between adjoining boards, adding depth without fitting individual spaced slats.

This profile allows secret fixing through the concealed fixing area, helping keep screw heads hidden for an uncluttered appearance. Face fixing is also an option where preferred or required by the installation.

Use suitable stainless steel fixings for exterior hardwood cladding. Pre-drill where required to reduce splitting, and follow the recommended fixing position, screw size and batten spacing for the profile.

Why Choose Iroko Cladding?

Iroko is a naturally durable hardwood valued for exterior joinery and cladding. Its benefits include:

• Natural durability – Iroko heartwood offers natural resistance to fungal decay.
• Distinctive appearance – golden and brown tones develop with exposure, giving each installation individual character.
• Hardwearing timber – a robust hardwood suited to demanding exterior applications.
• Smooth-planed finish – highlights the grain and creates a neatly machined surface.
• Versatile style – complements brick, stone, glazing and other natural materials.

Colour and Weathering

Left unfinished outdoors, Iroko gradually weathers towards silver-grey. To help retain its warmer tones, use a suitable exterior finish, such as an appropriate Osmo UV-Protection Oil.
