Tubular vs solid chipboard door core: how to choose

A door core is the hidden filler inside a flush door. It sets the weight, the feel and the cost of the finished door.

A tubular chipboard core is a particle board panel with round tubes running through it. It is lighter and uses less material, so it suits high-volume interior doors where weight and cost matter.

A solid chipboard core is a full-density panel. It is heavier and firmer, and is chosen when a door needs a more substantial core.

If you are unsure, send us your door size, thickness, finish and quantity. We will suggest the right core and quote it.
