There are two main types of doors namely Paneled and Flush. Both types are available in exterior and interior grades. Exterior doors are thicker and stronger to withstand weather and intruders
Paneled doors can usually be reduced by up to 18mm all round, but flush doors can only be reduced by a few millimeters at best. Paneled doors have a timber framework consisting of two vertical stiles and two or more horizontal rails. These enclose panels made of plywood, timber or glass.
Flush doors consist of a light, timber frame faced with sheet material. The cheapest doors have a honeycomb cardboard core (hollow core) and hardboard faces. Slightly more expensive doors are faced with plywood. Others have heavier, laminated timber or chipboard cores or timber rail cores. All flush doors have built-in blocks for fixing hinges and locks; some may also have blocks for other door furniture.
