Introduction to Door Casing
Door casing is an essential architectural element that frames a door, providing a finished look to the doorway. It not only enhances the aesthetic appeal of the door but also protects the wall edges around the door from damage. Door casings come in a variety of styles, materials, and finishes, allowing homeowners and designers to choose the one that best suits their overall interior design theme. Common materials for door casings include wood, MDF (medium – density fiberboard), PVC, and composite materials. Wood casings offer a warm and natural look, while PVC and composite casings are more durable and resistant to moisture. Door Casing
