The document discusses different types of false ceilings, including gypsum, metal, wood, and PVC. Gypsum false ceilings are made of gypsum boards suspended from metal frameworks and provide insulation and fire resistance. Metal false ceilings use metal tiles and frameworks and are durable and customizable. Wood false ceilings add warmth but also insulate, while PVC ceilings are cost-effective but also fire resistant. False ceilings enhance aesthetics, insulate, reduce noise, and increase fire safety while being easy to maintain. The right type depends on the space's specific requirements.
