Interior materials refer to the various substances used in the construction and decoration of indoor spaces. Common materials include wood, drywall, tile, and carpet. These materials contribute to the aesthetics, functionality, and comfort of a room, influencing factors like insulation, acoustics, and durability. Different interior materials serve specific purposes. For example, ceramic tiles are often used in kitchens and bathrooms due to their water resistance, while plaster can create smooth wall finishes.
