Who this guide is for
- Homeowners choosing interior doors
- People comparing hollow, solid-core and panel doors
- Anyone wanting quieter or more solid-feeling doors
- Homeowners briefing a supplier or fitter
Door core and construction
Interior doors are commonly hollow-core, solid-core or solid wood, and the core drives weight, sound and feel. Hollow doors are light and cheap; solid cores feel substantial and dampen sound.
Choose the core around what the room needs, since not every door has to be the same.
- Hollow, solid-core and solid wood differ
- Core drives weight, sound and feel
- Match the core to each room's needs
Sound and privacy
Solid-core doors block more sound than hollow ones, which matters for bedrooms, bathrooms, offices and any room where privacy or quiet is valued.
Where sound matters, the door is one factor among several; serious soundproofing is a professional question, but a solid door helps.
- Solid cores block more sound
- Matter for bedrooms, bathrooms and offices
- A solid door helps but is not full soundproofing
Style and panel options
Door style sets a room's character: flush doors read modern, panelled doors read traditional, and glazed doors borrow light between rooms.
Choose a door style that suits the home and consider glazed doors where you want to share light into darker spaces.
- Flush, panelled and glazed doors differ in style
- Glazed doors share light between rooms
- Match the style to the home
Durability and finish
Doors take knocks, especially in busy and children's areas, so more robust doors and durable finishes last better there. Painted and veneered finishes read differently.
Match door durability to the room, favouring sturdier doors in high-use areas.
- Doors take knocks in busy areas
- Robust doors and finishes last better
- Match durability to the room
Coordinating doors across the home
Consistent door style and finish across the home reads as deliberate, while hardware ties it together. Coordinate doors with trim and the overall palette.
Plan doors, hardware and casing as a set so each room's entrance reads as part of the whole.

Frequently asked questions
Questions readers ask about this topic
What is the difference between hollow and solid-core doors?
Hollow-core doors are light and budget-friendly but block less sound, while solid-core and solid wood doors feel substantial and dampen sound better. The core drives weight, sound and feel, so match it to each room's needs rather than using one type everywhere.
Which doors are best for sound and privacy?
Solid-core doors block more sound than hollow ones, which matters for bedrooms, bathrooms, offices and any room where privacy or quiet is valued. A solid door helps, but it is one factor among several, and serious soundproofing is a separate professional question.
Should interior doors all match?
Consistent door style and finish across the home reads as deliberate, with coordinated hardware tying it together. You can vary doors by room need, such as solid cores where quiet matters, while keeping a coherent style, trim and palette throughout the home.
Are glazed interior doors a good idea?
Glazed doors borrow light between rooms, which is useful where you want to share daylight into darker spaces while still separating rooms. They are one style option alongside flush and panelled doors, so choose based on light needs and the home's character.
