Interior Doors are the types of doors or hinged movable barriers that users use to enter or leave a space. Interior Doors are designed to perfectly fit the doorway of a room. Interior Doors are typically attached by hinges to a door frame or wall and move at an angle away from the doorway. Interior Doors also often incorporate locking mechanisms and door knobs into their design. Interior Doors may embrace intricate designs to suit the space they are in or have a minimalist surface. Interior Doors are typically made of wood, fiberglass, UPVC/vinyl, or composite materials.
Interior doors and exterior doors are different in terms of their function, material, security, insulation, size, design, and hardware. Interior doors are used to separate rooms within a building and are typically made of wood, while exterior doors provide a barrier between the interior and exterior of a building and are typically made of weather-resistant materials such as wood, steel, fiberglass or composite. Exterior doors have to provide more security and insulation than interior doors, and have weather stripping and threshold to keep out weather and pests.
Interior doors are designed to swing into rooms to save space and prevent the door from blocking walkway when it's open. It also makes it easier to close the door, as the doorknob is closer to the person closing it.
It is possible to soundproof interior doors by using methods such as weatherstripping, door sweep, door seal, mass-loaded vinyl, soundproofing paint or sprays, and installing acoustic doors. These methods can help to reduce sound transmission but may not completely eliminate it. Combining multiple methods can increase the level of soundproofing.
