About this product
3.6m Deluxe Woodgrain Cladding Board features a natural woodgrain surface texture for a classic, authentic timber look. This 174mm x 21mm board is available in a 3.6m length, ideal for standard wall heights. The woodgrain finish provides a beautiful, traditional aesthetic while offering the superior performance of composite materials. Available in all eight Deluxe range colours.
Why choose Deluxe composite cladding?
- Class D Fire Rated. Our Deluxe composite cladding boards are Class D fire-rated, suitable for use on low-rise residential and commercial developments under 11m in height.
- Embossed Woodgrain. A deep, multi-layered embossed woodgrain with medullary rays and knots emulates real wood, with each shade having its own unique two-tone facets.
- Fade And Stain Resistant. UV inhibitors prevent fading so boards retain their bright tone throughout their lifespan. The capped Deluxe board is 100% waterproof, so spills and rainwater cannot seep in or stain.

Installation & Care
Before you start: allow boards to acclimatise on site and plan your layout (horizontal or vertical). Slatted panels include integral backing, so no separate backer board is required.
Fitting: fix to a suitable battened subframe using the matching NeoTimber clips and screws, leaving the recommended expansion gaps. Use the edging options to finish neatly around windows and doors.
Routine care: wash down periodically with warm soapy water and a soft-bristled brush to keep the surface looking its best – no staining, painting or treating required.

Installation Guide
Composite cladding installs onto a battened wall — a competent DIYer can clad a small wall in a day. Always work upwards from the bottom.
Prepare the wall
Ensure the substrate is sound, dry and flat. Fix pressure-treated 25mm timber battens vertically at 600mm centres, plumb and level. On masonry, use rawl plugs and stainless screws.
Fit the starter trim
Install a horizontal starter trim at the lowest course, perfectly level. Leave a 10–15mm gap from the ground for drainage and ventilation.
Install the first board
Slot the first board into the starter trim. Secure the top edge through the hidden fixing groove with stainless steel screws into each batten.
Continue boards upward
Each successive board interlocks with the one below. Fix through the hidden groove at every batten — no face fixings visible. Stagger end joints by at least 600mm across courses.
Cut around openings
Use a fine-tooth circular saw or jigsaw. Mark boards in place, cut on the back face to avoid chipping the show face. Seal cut ends if exposed.
Finish with corner trims
Fit matching corner trims, end caps and a top trim to weatherproof the assembly. Leave a 5mm expansion gap behind every trim.
