WPC piano-profile louvers for walls, ceilings and partitions.

The Decoinn Piano Louver takes its name from its distinctive stepped profile — ridges of varying width that rise and fall across the surface like keys, creating a layered play of light and shadow that feels crafted rather than repetitive. Built from WPC, a composite of wood fibre and polymer, Piano offers the warmth and density of natural timber without any of its weaknesses. It will not warp, swell, split or attract termites, and it holds its finish beautifully in humid Indian conditions where real wood eventually fails. At 10 MM, Piano is lighter and easier to handle than heavier louvers while still delivering a solid, premium feel. The tongue-and-groove joint lets panels run continuously with no visible seams — ideal for long feature walls, ceiling runs and semi-open partitions in homes, offices and hospitality spaces.
