- Widest profile range: Nordic spruce is available in more profile types than any other UK cladding species — shadow gap, double shadow gap, tongue & groove, shiplap, feather edge, loglap, rainscreen and structural double T&G.
- Most popular for contemporary homes: Shadow gap 19x146mm — clean horizontal rhythm, works in natural, grey, black, and charred finishes.
- Most popular for sheds & outbuildings: Shiplap 19x146mm — the UK's most widely used shed cladding profile.
- Most versatile: Tongue & groove V-joint — suitable for exterior cladding and interior lining in one profile.
- Best for charred black: Rainscreen — the narrow open-joint batten creates maximum shadow depth and takes charred finishes extremely well.
- Key reminder: All Nordic spruce profiles require treatment every 2–4 years — Durability Class 4. For zero maintenance, see ThermoWood profiles or Siberian larch profiles.
Nordic spruce offers the widest profile range of any cladding species we stock — eight distinct profile types covering every exterior cladding application from contemporary shadow gap residential to rustic loglap garden rooms and budget shiplap sheds. All profiles share the same species characteristics: the most affordable cladding timber in the UK market, consistent pale cream colour that takes stains and charred finishes exceptionally well, and Durability Class 4 performance that requires consistent exterior treatment every 2–4 years for structural longevity. This guide covers every Nordic spruce cladding profile available from UK stock — what each looks like, where it works best, sizes, costs, and how to choose between them.

Nordic spruce treated cladding — factory-treated Nordic spruce accepts a wide range of exterior stains and finishes, making it one of the most flexible cladding substrates available. Treatment every 2–4 years is essential for all Nordic spruce exterior profiles.
Shadow Gap — The Most Popular Contemporary Spruce Profile

Nordic spruce shadow gap cladding — the rebated board face creates a continuous horizontal shadow line that is the defining profile of contemporary UK cladding across all species. In Nordic spruce it delivers the contemporary look at the most affordable price point.
The rebated board face creates a recessed joint that reads as a continuous horizontal or vertical shadow line. The most popular Nordic spruce profile for contemporary UK homes, extensions, and garden rooms. Works particularly well with black or grey stained finishes and as a charred Shou Sugi Ban base. Three sizes give control over joint frequency — 120mm boards produce a tighter rhythm; 146mm produces fewer, bolder joints per metre height. Treat every 2–4 years.
A wider, thicker 24mm board with a deeper double rebate — bolder and more prominent shadow line than the standard profile. The additional board depth adds rigidity, making this the preferred choice for larger residential facades and commercial projects where a more architectural horizontal statement is the design intent.
Tongue & Groove V-Joint — The Most Versatile Spruce Profile

Nordic spruce tongue and groove cladding — the interlocking joint with V-chamfer at each board junction creates a clean, traditional cladding face suitable for both exterior and interior applications. The widest size range of any Nordic spruce profile.
The only Nordic spruce profile that works equally well as exterior cladding (with treatment) and interior timber lining. The interlocking tongue and groove joint with V-chamfer at each face creates a subtle decorative groove line across the cladding face. Available across the widest depth range — 14mm through 28mm — giving options for lightweight interior use through to heavy-duty exterior boarding. The most cost-effective Nordic spruce profile for most applications.
Shiplap, Feather Edge and Loglap — Traditional Profiles

Nordic spruce feather edge cladding close-up — the tapered overlapping profile creates a pronounced shadow at each board lap. The most traditional UK cladding profile, available in Nordic spruce at the most competitive price of any featheredge species.

Nordic Spruce as a Charred (Shou Sugi Ban) Cladding Base
One of the most significant uses of Nordic spruce cladding in the UK market is as the base timber for charred (Shou Sugi Ban) finishes — and it excels in this role. Nordic spruce's straight, consistent grain chars evenly and cleanly, and the pale cream base colour means the charred surface is a deep, true black with no warm undertone. The shadow gap and rainscreen profiles are the most popular charred spruce specifications for contemporary architecture — our Nordic spruce charred brushed stained black is one of the most specified charred cladding products we supply.
The charring process significantly extends the effective service life of Nordic spruce beyond its standard Class 4 rating — the carbonised surface provides biological resistance that the unmodified timber lacks. A charred Nordic spruce facade requires minimal maintenance and outperforms untreated spruce in almost every weather exposure scenario. For the full picture on black and charred Nordic spruce see our black feather edge guide and black timber cladding UK guide.
Which Nordic Spruce Profile Is Right for Your Project?
Every Nordic spruce profile is also available in Siberian larch and most in ThermoWood — so if you have chosen a profile based on visual preference, you can upgrade the species for lower maintenance without changing the look. Nordic spruce is the right species choice when budget is the primary driver and consistent treatment is planned. If maintenance may be inconsistent, larch or ThermoWood in the same profile is a better whole-life decision at a higher starting cost.
What cladding profiles are available in Nordic spruce?
Shadow gap (14x120, 19x120, 19x146mm), double shadow gap (24x146mm), tongue & groove V-joint (14x120, 19x146, 28x146mm), shiplap (14x120, 19x120, 19x146mm), feather edge (24x146mm), loglap (24x146mm), rainscreen (24x68mm), and double tongue & groove structural (45x146mm). The widest profile range of any UK cladding species.
What is the most popular Nordic spruce cladding profile?
Shadow gap 19x146mm for contemporary residential projects. Shiplap 19x146mm for sheds and outbuildings. Tongue & groove V-joint for versatile interior and exterior use. Feather edge for barns and rural buildings.
What size Nordic spruce cladding boards should I use?
19mm depth is the standard exterior specification. 14mm for interior or very sheltered exterior positions. 24mm for feather edge and double shadow gap where greater rigidity is needed. 146mm width for fewer, bolder joints; 120mm for a tighter, more frequent joint line.
Does Nordic spruce cladding need treating?
Yes — Durability Class 4, treatment every 2–4 years is essential for structural performance. Apply exterior oil or stain to all board faces before installation and re-treat on schedule. For zero maintenance, the same profiles are available in Siberian larch (Class 3) or ThermoWood (Class 2).
