Moulded doors

   Core material: Material within the door used simply to fill space, provide rigidity and reduce druminess.
   Hollow-core - Often consists of a lattice or honeycomb made of corrugated cardboard, or thin wooden slats. Can also be built with staggered wooden blocks.   Hollow-core flush doors are commonly used as interior doors. 
   Lock block - A solid block of wood mounted within a hollow-core flush door near the bolt to provide a solid and stable location for mounting the door's hardware. 
   Stave-core - Consists of wooden slats stacked upon one another in a manner similar to a plank & batten door (though the slats are usually thinner) or the wooden-block hollow-core (except that the space is entirely filled).
   Solid-core - Can consist of low-density particle board or foam used to completely fill the space within the door. 
   Solid-core flush doors (especially foam-core ones) are commonly used as exterior doors because they provide more insulation and strength. 
   Skin - The front and back faces of the door are covered with HDF / MDF skins.
