Wooden false ceilings come in different types including drop ceilings, ceiling tiles, plank ceilings, coffered ceilings, and suspended ceilings. They are made from hardwood like teak or medium density fiber, and provide both aesthetic and functional purposes in buildings. Wooden false ceilings have advantages like providing decorative looks, insulation, and a warm feeling, but also have disadvantages of being expensive, prone to termites, and difficult to clean.
