Three places that change a room, in under a centimetre of thickness
Skirting, slat panelling and door casing are all 8–12 mm thick, yet they are the lines the eye reads to decide whether a room was finished properly. This page compares them one at a time, with real sections and prices.

One line that makes a room read as finished
A floor has to be laid with a gap at the wall so it can move with the weather. That gap, plus a plastered edge that is never quite level, is the first thing the eye reads as unfinished work. Skirting covers both with a single line.
Once a horizontal line runs round the room, the eye reads the room as having an edge — the wall no longer stops in mid-air. The room looks tidier without a single thing being moved, and the dark dust line that collects in the angle stops showing.
It is also the strip that meets a mop, a vacuum and the side of a shoe every day. PS can be washed without swelling, unlike timber or MDF, which have to come off the wall once they do.

A wall with shadow reads differently from a wall with paint
However good the colour, flat paint reflects light evenly across the whole surface, so the eye reads a flat plane. Cladding it in slats introduces real shadow in the grooves, and that shadow moves through the day. The same wall becomes a surface with depth.
Vertical lines also carry the eye upward, so a low ceiling feels less low, and a television wall stops being somewhere a screen hangs and becomes the thing the room is arranged around.
The advantage nobody mentions: a wall with waves in the plaster or old patch repairs disappears under slats. That is far cheaper than re-skimming the whole wall.

The edge that says whether the job was finished
However well an opening is plastered, a rendered edge is never as crisp as a straight line — and it is an edge everyone looks at anyway, every time they walk through.
Casing turns an opening that looks cut into one that looks intended. The two top corners meeting cleanly at 45° is the detail a visitor reads instantly as proper work.
It protects that corner as well. The wall beside a doorway is where luggage, trolleys and furniture legs land more than anywhere else in a house. Cracked plaster is hard to patch invisibly; replacing a length of casing is not.
