Wall Panel 63 Corner Strip: wrapping a corner in a 4cm profile

An external corner is where a panelled wall shows every millimetre of its cut edges. The Wall Panel 63 Corner Strip is the piece that covers that junction: a 240cm PVC length with a 4 x 4cm section, supplied ten lengths to a pack, finished to match the Panel 63 boards rather than to match your paint.

Four centimetres on each face, and why that helps

The listing gives the size as 4 x 4 x 240cm per trim. Read as a corner section, that points to roughly four centimetres across each of the two faces that meet at the angle. The listing does not break the figure down into what covers the board and what tucks behind it, so treat it as the overall section rather than a promised cover width. Either way it is a deeper return than the flat Panel 63 trim that runs along the edges and joins, which is why it is the profile to consider where a cut edge is not quite square or the wall behind it runs slightly out of plumb. The listing carries no cross-section drawing and does not state how deep the profile sits over a board, so measure your panel thickness and put that figure to the shop before you buy a pack.

What one pack covers

Most rooms need far fewer than ten lengths, so the first sum to do is a count of corners, not a measurement of walls. Walk the room and count every external angle the panelling turns. Window reveals and a chimney breast are the ones people forget, and a chimney breast on its own takes two. If your ceiling sits above 240cm you will have a joint part-way up a corner, which is visible from across the room, so decide where it falls before anything is cut.

The finish letters are fitting instructions

The finish choice on the product page is not an open colour pick. Each option names the board it belongs to:

• A Oak for Panel 63A
• B Grey for Panel 63B
• T Walnut for Panel 63T

Order the letter printed on your panel packs. Two finishes sharing a colour word will not necessarily read the same side by side, and a corner strip from the wrong code is the detail you will keep noticing afterwards.

What else closes off a Panel 63 wall

Corners are only one junction. The flat Wall Panel 63 Trim handles edges and the joins between boards in the same three letters. Both sit in the wider trims and fittings range next to the equivalents for other board codes: the Corner Strip for WP 07/11, or the 300cm Aluminium Corner Strip where a longer length or a metal edge suits the job better. Check the panel codes on each one before mixing them, because they are not interchangeable.

Before you order

Have three things written down: the code on your boards, the number of external corners, and the height of the tallest one. Delivery is free within 50 miles of our Glasgow store and £50 beyond it. Order the Wall Panel 63 Corner Strip in the finish letter your panels carry, and if the label has worn off, send the shop a photograph of the board and ask which letter it is before you commit.
