The main feature of a solid core door is its increased strength. Solid core doors are constructed with a solid material, typically a composite or a solid wood core, which makes them more durable and robust compared to hollow core doors. This design provides superior resistance to impact, making them less prone to damage, which is particularly important in high-traffic areas or environments where security is a concern.

Solid core doors are also typically heavier than their hollow counterparts due to their dense construction, which contributes to their strength. The enhanced strength can improve the door's performance in terms of security as well, as they are more difficult to break through. While other features such as fire resistance, sound insulation, and the weight of the door are noteworthy, the defining characteristic that stands out with solid core doors is their increased structural integrity.
