Ventilation in interior doors: why air circulation is important

An interior door not only affects the appearance of a room, but can also play a role in air circulation. For proper ventilation, air must be able to move through the home. A gap under the door or a ventilation grille can help with this.

Why is ventilation under an interior door important?

In many homes, air is extracted from certain rooms. To properly replace this air, new air must be able to flow in. A small space under an interior door can ensure that air can move from one room to another. A completely sealed door can actually restrict this airflow.

A gap or a ventilation grille?

A gap under the door is a simple and unobtrusive way to allow air to circulate. In situations where more or targeted air supply is needed, a ventilation grille in an interior door can be used. A grille provides a fixed opening and can be used, for example, when a gap under the door is not sufficient.

What should you pay attention to with an interior door?

When installing or replacing a door, look at the existing ventilation in the home. Check whether air can be sufficiently supplied and extracted. With a ventilation grille, the placement and size are also important for good airflow.

Good air circulation starts with the whole home

An interior door is only one part of the ventilation system. A gap or grille is only useful if the air is also being supplied and extracted somewhere.

Practical tip: when in doubt, do not simply close off an existing gap under an interior door. First, check why the space under the door is there and how the ventilation of the home is arranged.
