Sustainable interior linings in a room structure focus on eco-friendly materials and practices that minimize environmental impact. Wall linings may use recycled or low-VOC materials like sustainable drywall or bamboo panelling. Ceiling linings might include acoustic tiles made from recycled content or low-impact materials that improve energy efficiency. Floor linings such as bamboo, reclaimed wood, or recycled carpets offer durability and are made from sustainable sources. These choices not only enhance the room's appearance and comfort but also contribute to a greener, more sustainable building practice.
