PARTICLE CORE (PC)

Core made of compressed wood particles, providing good dimensional stability and a uniform surface for veneering, suitable for standard interior doors.

STRUCTURAL COMPOSITE LUMBER (SCL/LSL)

Core manufactured from engineered wood (laminated or oriented wood strands/fibers), offering high mechanical strength and excellent structural stability for heavy-duty doors.

AGRIFIBRE (AG)

Core made from compressed recycled agricultural fibers, providing an eco-friendly alternative with consistent density and good machining and finishing performance.

MINERAL CORE (MC)

Core composed of non-combustible mineral materials, offering enhanced fire resistance, typically used in fire-rated or high-performance thermal doors.

SOUND TRANSMISSION CONTROL (STC)

A rating that measures a door’s ability to reduce sound transmission; the higher the STC value, the better the acoustic insulation.

HOLLOW CORE (HC)

Lightweight core reducing weight while maintaining sufficient rigidity for interior applications.
