Upstands
Upstands intended to sit at the rear of your kitchen worktops to hide the gap between them and an adjacent wall.
The gap is necessary to allow expansion of the kitchen worktop, though upstands can also help to accommodate an uneven gap if your walls are not totally straight.
Upstands thickness are 20mm even if the worktops is in 30 mm thickness, and they be in 70 mm high, 100mm or full high splashbacks.
Splashbacks are similar to upstands, but are much deeper, and are usually used behind ovens or sinks to protect the walls from splashing water or stains.
