Wall Panel 89B Grey Oak: planning a corner before you order

Outdoor panelling almost never stops at one flat wall. It turns into a return, wraps a seating corner, or runs round the back of a store. Wall Panel 89B in Grey Oak is one of the groups here that names a corner piece as well as an edge trim, which makes that job straightforward to plan.

Start with the corner, not the wall

The listing names two fittings: Wall Panel 88/89 End Trim at 290cm, and Wall Panel 88/89 Corner Trim at 290cm, both separate products in outdoor trims and fittings. Work out the corner first because it fixes where every panel afterwards lands. Decide which wall the corner trim sits on, then set your first full panel against it and work outwards. Do it the other way round and the cut panel ends up in the corner, which is the one place a narrow rip is obvious.

Count a corner trim for every external angle and an end trim for every exposed edge, including where the panelling stops short of a gate post or a window reveal. These are listed at 290cm to match the panel length, so a run taller than one trim needs a joint in the trim too.

Panels, packs and what they reach

Each panel is listed at 16 x 290 x 2cm when fitted and interlocked. That phrase is doing real work: the 16cm is the width on the wall after the panels lap together, so it is the figure to count with. Six panels at 16cm by 290cm comes to 2.784m², which is the published 2.78m² a pack.

• One pack covers 0.96m of wall width at the full 290cm height
• Two packs reach 1.92m, three reach 2.88m
• For a wall width in centimetres, divide by 16 for panels and by six for packs, then round up
• Add a panel for each notch around a tap, a downpipe or a light

At 290cm the panel usually clears a boundary wall in one length, so expect to cut to height rather than joint horizontally. Cut the waste off the bottom where the trim and the ground detail hide the edge.

Grey oak, which is two decisions at once

The colour name pairs a grey with an oak, so the finish has to work against both the greys and the timbers already in the space: render, a fence, decking boards, an aluminium door frame. The listing gives the colour name and describes textured slats, and nothing further about the grain or the sheen, so look at the photographs on the 89B product page in daylight before you commit a whole elevation to it. If the surroundings are warm brick, the plain oak in the same group is the safer match.

What the listing publishes, and what it leaves out

It describes an engineered PVC composite for outdoor use, calls the panels UV resistant, and says they hold colour and structural integrity under prolonged sun. There is no test standard, fire rating or panel weight published, no slat width or gap figure, and nothing about the fixings a given wall needs. The listing also asks, in capitals, that you quote the full product code and title when ordering, which is sensible given how close the 88 and 89 group names are. Ask the shop for the manufacturer sheet if you need any of the missing figures on paper.

The other finishes in the group are Wall Panel 89A in Oak, Wall Panel 89D in Dark Oak and Wall Panel 89T in Walnut, all 290cm in packs of six. Browse the rest under outdoor wall panels.
