Which type of door is formed with an interior core of laminated blocks of wood or mineral composition?

Solid-core doors are designed with a dense interior that is composed of laminated blocks of wood or mineral materials. This construction provides enhanced sound insulation and improved fire resistance, making them a preferable choice for areas where noise reduction or fire safety is a concern. The solid, heavy core of these doors results in a sturdier product that can withstand impacts and helps to maintain privacy within spaces.

In contrast, hollow-core doors contain a lightweight core structure, typically made of cardboard or honeycomb material, which makes them less durable and not as effective for sound insulation or fire resistance. Folding doors are designed to save space and can be made of various materials, but do not typically feature a laminated core. Glass doors primarily serve aesthetic purposes and generally do not have the same sturdy core structure as solid-core doors.
