Core Types

Core Types

A door should remain perfectly strong and stable despite the heat or cold it may face. A good door will also provide some noise reduction. A core is the main component of an engineered wooden door. PT Woodone Integra Indonesia uses various types of core, which are Honeycomb, Particle Board, Hybrid, Falcata/ Sengon, and FJL Hardwood.


Honeycomb core is a natural structures that have the geometry similar to a honeycomb, leading to the minimal usage of material. The benefit of honeycomb core are its low cost and lightweight, while maintaining its flat and strong stance, though it cannot reduce noises. Honeycomb core is typically used for economical internal door.


Particle Board core is made of solid core that is a mixture of wood chips, glued together with heat. resins, and hydraulic pressure, resulting a uniformed solid board with good sound insulation and good consistency, while keeping the door flat. Particle Board is typically used for internal doors and fire rated door with low moisture variations.


Hybrid Core is produced by layering particle board on the outer sides, and soft wood in between. This technology is rather advantageous compared to solid particle board which often leads to heavier doors. The benefit of Hybrid Core is its lightweight low thermal conductivity, and high value of temperature strength. Hybrid Core is typically used for internal door.


Falcata / Sengon core is produced by layering three core boards. The outer layers are wood grains put parallel, and the layer in between is cross grained. The right infill construction of Falcata / Sengon core is essential for its performance in enduring and resisting a great deal amount of stress and high moisture variations in everyday moves and handles as internal doors.


FJL (Finger Joint Laminated) Hardwood core is produced by finger jointed hardwood, providing additional strength and stability, while remaining its straight stance. FJL Hardwood core is typically used for external doors and fire rated doors.
