Construction Of A Fire Door

Most fire doors have a solid core construction which can include: particleboard, chipboard, flax board and solid timber. The assembly of a fire door can vary greatly, some have: a timber framing around the core with a laminated veneer; others have a lippings around the core with a veneer on top; and in some cases a plywood, veneer or MDF facing is glued on to the core without framing or lippings. There is no preferred construction method, as long as the desired fire rating is achieved.
