What are flush doors?

We’ve talked about all sorts of doors – acoustic doors, steel doors, fire doors – and we’ve even talked about some of the most beautiful doors in the world!  We’re now moving onto a different type of door (although there can be overlaps!) – the flush door.  Let’s take a look at what they are.


Flush doors are simple door designs that have plain facings on both sides.  They can be interior (more commonly) but also exterior.  They are often used where space is at a premium,  and would probably be placed towards the “functional” end of the door design spectrum rather than the “style” end … but as with anything a little imagination goes a long way!  They may be kept deliberately simple in appearance to highlight other features nearby.

Flush doors may have a solid, hollow or stave core.  If the core is solid – low density particle board or foam often being used to fill the space within the door completely – it may be supplemented with a type of laminate or plywood on each side.  Good for exterior doors as they provide more insulation and strength.

A flush door with a stave core will consist of wooden slats stacked upon one another.

If the core is hollow (i.e. where perhaps two sections of plywood have been attached to each side of a frame) some support may be built into the frame (such as a lattice or honeycomb support system made of corrugated cardboard).

Solid flush doors are, by definition, heavier than the alternatives, but are usually a more suitable option when their function is to form a passage between two rooms.

Their design is straightforward.  If they are intended to be mounted on tracks, the hardware will be recessed so that the doors can slide past one another.  This type of design might be used in a closet.

The doors have a perfectly flush surface, hence their name.

Other uses of flush doors

In addition to what we might describe as “normal” or everyday uses, flush doors can also be used for more specialised purposes such as:

  • fire doors
  • acoustic doors
  • X-ray doors

Bespoke flush doors

As with most types of door, several options are usually available with regards to size and finish and various other specifications.  Make sure that your supplier has a flexible approach and offers a wide range of standard but also bespoke alternatives.
