Panel Style Doors: A minimum of 2 panels and a maximum of 8 are permitted. Selection of geometric shapes for panels is also permitted. As an alternative to Flush type door leaves, panel appearance designs are now widely available which mostly reproduce traditional fielded paneled design. They are made using combination of solid timber and or Veneered panels with substantial intumescent reinforcement. Some designs employ molded door skins which are glued to both sides of a fire resisting central core.
