  • the prefabricated box 14 is placed above the hearth 5 on the strip 6, open downwards and extends inside the hood 7. It has a front wall and two vertical side walls which are not in contact with the hood 7, and a ceiling horizontal pierced for example with four outlet holes 15 for hot air and a central orifice 16 for the smoke duct 9.
  • the two side walls are in the example shown connected by the rear wall 3 which extends from the floor 4 to the ceiling of the housing 14.
  • the chimney 1 is advantageously completed by two lateral jambs 20 arranged between the hearth 5 and the pillars 2, resting on the hearth 4 and arranged to carry the horizontal strip 6.
  • These side legs 20 are made of a self-adhesive material bearing, thermally insulating and non-combustible. Therefore, they combine the load-bearing functions of the strip 6 and of the prefabricated box 14, of insulation thermal and fire protection pillars 2. More particularly, these jambs 20 are made from thermally insulating concrete based on vermiculite in accordance with the French patent application filed under the number 00/02840, this material having the advantage of offering both high mechanical strength and very high thermal insulation power.
  • thermal insulation sheet 21 such as Aluboard® or any other insulating product which has the power to reflect the heat.
  • this thermal insulation sheet 21 is arranged on the wall outside of the jamb 20 opposite the corresponding pillar 2 to increase the thermal protection of these pillars.
  • the other constructive elements of the chimney 1 such as the partition rear 3, the sole 4, the horizontal strip 6 and the prefabricated box 14 are advantageously made of thermally insulating concrete, like the jambs 20.
