61. Moulded doors

Stiles and rails - As above, but usually smaller. They form the outside edges of the door. 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.
Door swing directions diagram.Door swingsDoor swings, or handing, are always determined from the secure side of the door (ie. the side you use the key on, outside to inside, or public to private).Left hand hinge (LHH): If the hinges are on the left and the door opens in, it's a left hand door. You push the door with your left hand. Right hand hinge (RHH): If the hinges are on the right and the door opens in, it's a right hand door. You push the door with your right hand.


Left hand reverse (LHR): Standing in the house, the hinges are on the right, knob of left, pushing the door to the outside (outswing) Right hand reverse (RHR): Standing in the house, the hinges are on the left, knob of right, pushing the door to the outside (outswing) Sizing: A standard US door size 36" x 80" (0.91 m x 2.03 m).Note: In Australia, this is different. The fridge rule applies (you can't stand in a fridge, the door always opens towards you) - If the hinges are on the left then its a left hand (or left hung) door. If the hinges are on the right then its a right hand (or right hung) door. See the Australian Standards for Installation of Timber Doorsets, AS 1909-1984 pg 6.
