Sustainability is increasingly important in the interior doors market. Manufacturers are adopting eco-friendly materials such as FSC-certified wood, recycled composites, and low-emission MDF to reduce environmental impact. Water-based and low-VOC finishes ensure healthier indoor air quality.

Energy-efficient designs, such as insulated doors for thermal and acoustic performance, contribute to overall building sustainability. Consumers are increasingly preferring doors with longer lifespans and recyclable materials, supporting circular economy initiatives. By combining aesthetics with eco-conscious manufacturing, interior doors play a key role in sustainable building practices.
