4 Everdeck® Ash Grey Ultra Co-Extruded Composite Wall Cladding — 21 x 156 x 2900mm
4 Everdeck® Ash Grey Ultra composite wall cladding is a premium co-extruded composite board designed for exterior vertical surfaces. Use it to conceal unattractive walls, clad feature walls, or creatively match architectural elements — all with zero ongoing maintenance and a 20-year guarantee.
The tongue-and-groove profile with concealed fixing means no visible screws once installed, delivering a clean, professional finish on any exterior vertical surface.
Why Co-Extruded?
Unlike standard composite cladding, the 4 Everdeck® Ultra range uses a co-extrusion process that wraps the composite core in a solid polymer cap on all four sides. This cap provides superior protection against moisture, UV fading, staining, and surface scratching — which is why the Ultra range carries a 20-year guarantee compared to 10 years on the standard range. The colour is integral to the cap layer, not a surface coating, so it will not peel, flake, or fade over time.

How Much Cladding Do I Need?
Each board is 156mm wide with a tongue-and-groove profile. You will need 7.4 linear metres of cladding per square metre of wall area. To calculate your order quantity, measure the total wall area in m² and multiply by 7.4 to get the total linear metres required. We recommend adding 10% for waste and cuts.
Frequently Asked Questions
What is the difference between co-extruded and standard composite cladding?
Standard composite cladding is a single-layer board. Co-extruded composite wraps the core in a solid polymer cap on all four sides, providing significantly better resistance to moisture, UV fading, staining, and scratching. This is why the Ultra co-extruded range carries a 20-year guarantee versus 10 years on the standard range.
Is this cladding suitable for exterior use?
Yes. 4 Everdeck® Ash Grey Ultra is specifically designed for exterior vertical surfaces. The co-extruded composite construction is weather-resistant and requires no painting, sealing, or ongoing maintenance.
How is the cladding fixed to the wall?
The tongue-and-groove profile uses a concealed fixing system, meaning screws are hidden within the joint between boards. Once installed, no fixings are visible from the front face.
What maintenance is required?
None. The co-extruded composite material retains its colour and finish without painting, staining, or sealing. An occasional rinse with water is all that is needed to keep it looking its best.
What colours are available?
Ash Grey Ultra is one of four colours in the Ultra co-extruded range. Also available in White Ultra, Redwood Ultra, and Walnut Ultra — all available on our website.
