Wall Panel 17C Dark Grey: wide slats, coverage and pack maths

The 17 group is the wide-slat member of the slat panel family, and Wall Panel 17C in dark grey is the darker of its two greys. The listing gives a slat width of 5cm and a 1cm space between slats, and this is the group the catalogue names wide slat; the other panels in the slat and acoustic panel range carry their own slat figures on their own listings. That pitch, rather than the colour, is what you read from across a room.

A 5cm slat and a 1cm gap, drawn out

Add the two listed figures together and the pattern repeats every 6cm. Across the listed 60cm panel width that is ten repeats, so roughly ten slats a panel and forty across the 2.4 metre run a pack gives you. Panels with a narrower slat repeat more often and read busier at the same distance, but each of those listings carries its own slat width and spacing, so compare the figures rather than taking it from this page. One thing the figures here cannot settle is whether each panel edge finishes on a slat or on a gap, which is what makes that slat count approximate and what decides how tidy the joint between two panels looks. Check it against the photographs, or ask the shop, before you set the wall out.

What one pack covers

Measure the wall at skirting height, at shoulder height and just under the ceiling, then work from the widest of the three readings. Divide that by 2.4 metres, round up, and you have your pack count. The 240cm panel height suits a standard ceiling with a trim or a shadow gap at the top. If your wall is taller, you are choosing between a visible horizontal joint and the 280cm panels elsewhere in the range, which come three to a pack.

Dark grey, and what it asks of the room

A dark slat wall reads darker than a dark flat wall, because every gap sits in its own shadow. In a north-facing room that can be exactly the point, or it can be a wall nobody notices; a lamp or a picture light aimed along the slats is what brings the texture back out. Against white woodwork the line is hard and graphic, against oak flooring it settles down. The listing names the finish dark grey and shows it in two photographs. It does not quote a sheen level, a colour reference, or the colour of the felt behind the slats, so if that backing will be visible at a corner or a window reveal, ask first.

Sound: the claim, and the figure nobody has published

The description says the panels are HDF slats on a felt backing, and that they absorb sound and dampen noise. It also mentions reducing noise transmission. Those are two different jobs: softening the echo inside a room, and stopping sound passing through the wall into the next one. No absorption coefficient, no NRC and no breakdown by frequency is published for this panel, so read the wording as a description rather than a measurement. Where a number is actually required, for a studio or a meeting room, ask the shop for the manufacturer's test data before you commit.

Trims, fixings and ordering

The listing names Wall Panel PVC Trim Acoustic as the trim for this panel. That is the piece covering a cut edge at an external corner, or where panelling stops partway along a wall, and it is ordered separately from panel trims and fittings. The wall panel adhesive sits in the same part of the catalogue. Nothing on the listing states a fixing method, a panel weight, or whether screws can be used as well as adhesive, so check that against your wall build-up: plasterboard, battens and solid masonry are three different jobs.

Either side of this finish, on the same wide-slat profile, sit Wall Panel 17B in light grey and Wall Panel 17E in black: same size, same slat width, a different weight of colour. Once the wall is measured and the pack count rounded up, the full figures and both photographs are on the Wall Panel 17C dark grey page.
