plafondlaag

Plafondlaag is the finishing layer applied to the underside of a ceiling. It creates the visible surface and contributes to appearance, fire resistance, acoustics, and insulation. The plafondlaag is laid over a substrate such as a timber or metal frame, plaster, or gypsum board, and can consist of traditional plaster, lime plaster, gypsum plaster, or a skim coat on drywall. In modern construction it is often realized as a gypsum-board ceiling with a finishing coat or joint compound; older or stylistic ceilings may use stucco or decorative plaster.

Functions include providing a smooth, paintable surface, concealing construction irregularities, and, depending on material, improving acoustics or fire performance. Design variations range from plain flat ceilings to coffered, curved, or acoustically treated surfaces.

In renovation, the plafondlaag is assessed for moisture, cracking, or delamination and may be repaired by re-plastering, re-skimming, or re-finishing. The term is common in Dutch architectural and construction contexts, especially in the Benelux region.
