What type of core in door construction is made from bonded lumber or particle board?

A solid core door is constructed with a core that is made from materials such as bonded lumber or particle board, which gives it a dense and heavy feel. This type of core provides significant sound insulation and durability compared to other types. Solid core doors are especially beneficial in environments where privacy and security are priorities, such as in commercial spaces or private offices.

The composition of the solid core makes it more resistant to impact and wear, thus enhancing its lifespan. The use of bonded materials also contributes to its stability, helping to prevent warping over time. In comparison, other options such as hollow core doors utilize a much lighter structure and are not suited for applications where sound and security are major concerns.
