What is the purpose of an interior door?

Interior doors seal off rooms and hallways to break up airflow, to increase privacy and to help control the way noise travels throughout the house. Doors in your home can be used to regulate heat and cold, which in turn can have a significant impact on your comfort and power bills. They’re also used to seal off important rooms from prying eyes. Most homes have doors installed in just about every entrance to a room, except for large entrances such as archways.

What qualities should a good interior door have?

A good interior door should be able to work well with zoned climate control, helping to regulate temperatures in individual rooms. It should also do its part to keep noise and sound in or out of a room, and where necessary, offer the option of privacy.

Bathroom doors in particular are vulnerable to humidity, so be sure to take this into account both in the materials and/or in the paint you use on it. It’s very important for interior doors to fit your overall design scheme too, providing a natural flow to the house and matching the colour scheme. Poorly chosen or inappropriately coloured interior doors will stick out like a sore thumb.

What sort of doors are appropriate for interior doors?

Where there is available space, hinged doors are the most common choice for interior doors. Sliding doors are also used in many homes, normally where the doorway spans a larger distance (e.g. where a hallway meets a living room), or where space is a limitation. Where a sliding door is impractical (i.e. where there’s no place for it to slide), you may also wish to consider a small bifold door as a means of conserving space.

Hollow core doors normally offer perfectly good thermal and acoustic insulation, although if you’re after extra insulation against either of these things and aren’t limited by budget, then a solid core door will usually perform better.
