How to Choose a Wall Panel by the Room It Goes In

Why the room comes before the panel

A wall panel does one of four jobs: it decorates a dry interior wall, it survives a humid room, it clads an exterior elevation, or it controls echo. Those are different materials, and a supplier who sells you the same panel for all four has not asked what the room is. Start by describing the room in those terms and most of the catalogue disappears.

Dry interior walls

Interior WPC panels and PS panels live here. Interior WPC comes in 160mm, 195mm, 196mm and 210mm modules at 2900mm length, with depths from 10mm to 23mm, and a smooth wood veneer finish. PS panels run 150x12mm and 160x10mm at 2.9m in polystyrene, lighter and cheaper per metre, cut with a hand saw. Both arrive finished, so there is no staining or sealing on site.

Humid rooms and wet areas

Bamboo charcoal panels are formaldehyde-free and VOC-free with a charcoal core that absorbs odours, and they are water and mildew resistant, which is what keeps them flat where paint blisters. PVC wall panels give a fireproof, waterproof, scratch resistant board with a service life exceeding 15 years. For the ceiling above a shower or a cooker, PVC ceiling panels weigh about a third of ceramic tile.

Exterior elevations

Outdoor WPC cladding is a different board: 219x26mm or 156x21mm, 60% wood fibre with recycled HDPE, and a co-extruded skin that is laid down with the core rather than bonded on afterwards. That skin is the reason it resists fading, and it is the reason an interior panel does not belong outside.

Rooms with an echo problem

A fluted panel looks acoustic and does nothing measurable. A wood slat acoustic panel works because sound entering the gaps between the slats meets a felt made of recycled plastic behind them, and friction and vibration consume the energy. If the complaint is speech intelligibility, this is the only range here that addresses it.

Choosing the module and the depth last

Module sets the rhythm: 160mm gives fine lines, 210mm covers the most wall per piece. Depth sets the shadow: 10mm and 12mm read nearly flat, 23mm throws a strong line. Ask for samples in two depths and look at them under the room's own lighting before committing a whole project.
