DECNO composite façade boards used as exterior cladding

Composite façade boards

Narrower than cladding, the façade board draws tight lines and a steady rhythm over the full height of a wall.

The four things to check

01

Width

150 mm draws a tight rhythm; mix in 71 mm boards to break the regularity.

02

Single-sided

Only one face is worked: cheaper than double-sided for wall use, where the back is never seen.

03

Fixing

Concealed clips for a façade with no visible screw heads — the detail that makes the difference.

04

Exposure

Facing due south, favour mid shades: they age more discreetly than very light ones.

Where wide cladding goes for mass, the composite façade board goes for line. At 2900 mm long and 150 to 153 mm wide, it multiplies the lines and produces a more graphic, more contemporary result — the one you see on architect-designed villas from California to Casablanca.

Three shades, three handwritings

Ipé (2900 × 153 × 21 mm) is the thickest and most structured: a deep brown that catches late-afternoon raking light well. Walnut V2 and Teak V2 (2900 × 150 mm) are the updated versions of our two best-sellers, with reworked graining that repeats less from board to board.

Vertical or horizontal

Fitted vertically, the board makes the building taller and sheds rainwater naturally along the joints: that is the orientation to favour on a heavily exposed façade. Fitted horizontally, it stretches the volume and gives that calm horizontality of seaside architecture. Either way the principle stays the same — ventilated cladding: frame, air gap, concealed clip fixing.

Mixing widths

A detail our architect customers use often: alternating 150 mm façade boards with 71 mm flat boards on the same surface. The irregular rhythm breaks the monotony of a large wall and reads as a bespoke design, at no extra cost.

Frequently asked questions

What we get asked most often

What is the difference between façade boards and cladding?
A matter of width and profile. Cladding is 169 to 222 mm with an overlapping joint; a façade board is around 150 mm and draws a finer pattern. Technically both install the same way, as ventilated cladding on a frame.
Can façade boards go on an externally insulated wall?
Yes, it is a common case. The frame is fixed through the insulation into the loadbearing substrate, using thermal-break brackets. The air gap between insulation and cladding is still essential.
How many boards per square metre?
With a 150 mm effective width plus an installation gap, allow roughly 6.9 linear metres per m², or 2.4 boards of 2.90 m. Budget 8 to 12 % for offcuts depending on how many openings you work around.
Do the boards expand lengthways?
Slightly, as all composites do. On a 2.90 m board facing due south, allow 4 to 5 mm of gap at the ends. That gap is hidden behind a corner trim or a finishing profile.
