Wall Panel 37WT Walnut: deep slats, dark finish, light

Of the slat panels listed here, Wall Panel 37WT in walnut makes about the strongest wall: a dark finish, a wide 4cm slat, a 1cm gap and a 2.2cm panel, so the shadow in each gap is deeper and the line between slats is heavier. Four panels come to a pack, each 60 x 240cm.

A dark finish takes light out of a room

A wall like this absorbs light instead of returning it, and the gaps between slats read as near-black lines rather than shadows. In a south-facing room with a good window, that is the whole point. In a north-facing room, a hallway or anywhere the only light is a central pendant, the texture goes flat after dark and the wall becomes a dark mass. The fix is light aimed at the wall rather than at the room: a wash from above, a floor lamp close to the face, or picture lights. Decide that at the same time as the panel, because the wiring is easier before the wall is covered.

What is published

• Panel: 60 x 240 x 2.2cm each
• Slat width: 4cm, with 1cm between slats
• Pack: four pieces, 5.76m² of cover
• Construction: HDF slats on a felt backing

The 4cm slat and the 1cm gap give a 5cm repeat, which divides a 60cm panel twelve times without a remainder. That is arithmetic, not a stated slat count, but it means the rhythm meets the panel edge cleanly and a wall planned in multiples of 60cm needs no fudged cuts.

Coverage, and the awkward last panel

Divide the wall width by 60 for panels and by four again for packs, rounding up each time. The place it gets awkward is a width like 3.3m: five full panels plus 30cm. Rather than leaving a narrow half panel at one end, take the surplus off both ends so the wall is symmetrical, and plan each cut to fall in a gap between slats instead of through the middle of one. The listing does not say what a cut slat exposes, so plan the cuts to fall in a gap and ask the shop about an edge trim if one has to land on a slat.

Where the specification stops

The walnut is named and not described, so there is nothing on the listing to tell you where it sits between a mid brown and a deep red-brown, how heavy the grain is, or whether the walnut is a veneer or a wood-effect finish. The backing colour is not given either, which matters more here than on a pale panel because you see it in every gap. And the acoustic wording, that the slats and felt absorb sound and reduce noise, carries no coefficient and no test standard, so it describes the build rather than measuring a result. All three are quick questions for the shop and worth asking before a whole wall is committed.

The narrower walnut, and the taller one

For the same colour with a finer rhythm and a slimmer panel, Wall Panel 36WT is 2.5cm slats on 1.7cm, which also takes less off the room. If the wall is taller than 240cm, Wall Panel 02WT is the 280cm walnut panel. The same wide slat in a cooler tone is 37F in grey oak, and the trims that finish an end or a corner are in panel trims and fittings, each listed against the panel numbers it suits, so check which one fits this panel.

Sort the lighting, measure twice, then order the Wall Panel 37WT walnut acoustic panel for the whole wall together, and browse the alternatives in slat and acoustic panels first if you are still deciding. Delivery is free within 50 miles of the Glasgow store and £50 beyond.
