Flush door or solid door: what is the difference?

When choosing a new interior door, you will come across various door constructions. Two common options are a flush door and a solid door. The difference mainly lies in the structure, weight, and price. But what do you notice about this in practice?

What is the difference between a flush door and a solid door?

A flush door has a relatively light core and thin door faces. This makes the door easy to handle and install. A solid door has a much denser and heavier structure. Note: a solid door does not necessarily have to consist entirely of solid wood; it is primarily about the sturdy, full construction.

Weight and quality

A flush door is light and therefore practical for installation or when a door is used frequently. A solid interior door feels heavier and more robust. The higher weight does mean that properly fitting hinges and locks are important. The construction and materials used can also influence sound insulation.

What is the difference in price?

Flush doors are generally more affordable than solid doors. A solid door uses more and heavier materials and therefore often has a higher price. The final costs also depend on the finish, design, and material.

Which interior door suits your situation?

A flush door is a practical choice when a light and affordable door is desired. A solid door is better suited when a heavier, robust appearance and certain insulation properties are important.

Practical tip: do not just look at the price of the door. Also take the weight into account and check whether the existing frame, hinges, and door hardware are suitable.
