The louvre assembly includes a louvre housing having a continuous louvre housing perimeter wall; a louvre housing cavity surroundingly defined and formed by the louvre housing perimeter wall so as to have first and second laterally spaced open faces; and a louvre formation comprising a plural array of louvre slats removably mountable within the louvre housing cavity. The louvre assembly additionally or alternatively further includes a baffle formation removably mountable over said first open face and comprising: an apertured first closure plate associatively engageable with the louvre housing to seat over said first open face; an unapertured baffle box back plate; a baffle box perimeter formation extending between and laterally spacing apart the first closure plate and the baffle box back plate and forming thereby a baffle cavity; the baffle box perimeter formation having at least one apertured portion communicating with the said baffle cavity. Doors and/or housing structures incorporating such louvre assemblies are also described. ## Claims ### Claim 1 A louvre assembly comprising: a louvre housing having a continuous louvre housing perimeter wall;

a baffle box perimeter formation extending between and laterally spacing apart the first closure plate and the baffle box back plate and forming thereby a baffle cavity; the baffle box perimeter formation having at least one apertured portion communicating with the said baffle cavity. ### Claim 10 (depends on 9) The louvre assembly according to claim 9, wherein the baffle box perimeter wall defines at least one apertured portion communicating with the baffle cavity located towards the top of the said baffle cavity. ### Claim 11 (depends on 9) The louvre assembly according to claim 9, wherein the baffle cavity is divided by a baffle cavity divider positioned between the first closure plate and the baffle box back plate, extending from a base of the baffle cavity for at least a major part of an upward extent of the baffle cavity and serving to fluidly isolate a first sub-volume of the baffle cavity proximal to the first closure plate and a second sub-volume of the baffle cavity proximal to the baffle back plate. ### Claim 12 (depends on 9) The louvre assembly according to claim 9, wherein the baffle box perimeter formation defines a square or rectangular perimeter and comprises a bottom wall, two side walls and a top. ### Claim 13 (depends on 12) The louvre assembly according to claim 12, wherein the top comprises an apertured top wall or an open top in which a top wall is absent. ### Claim 14 (depends on 9) The louvre assembly according to claim 9, wherein the baffle box perimeter formation spaces apart the first closure plate and the baffle back plate such that the first closure plate and the baffle back plate are conveniently parallel and disposed vertically. ### Claim 15 (depends on 1) The louvre assembly according to claim 1, comprising an apertured first closure plate configured to extend across and beyond the area of the first open face defined by the louvre housing perimeter wall, having a first closure plate perimeter portion so extending beyond. ### Claim 16 (depends on 15) The louvre assembly according to claim 15, wherein the first closure plate perimeter portion is provided with fixing formations to perform at least one of the following: fix the first closure plate to the louvre assembly; fix the louvre assembly into a through opening in a door in use; and fix the louvre assembly into a through opening in a housing wall in use. ### Claim 17 (depends on 1) The louvre assembly according to claim 1, comprising an apertured second closure plate associatively engageable with the louvre housing to seat over the second open face wherein the second closure plate is configured to extend across and beyond the area of the second open face defined by the louvre housing perimeter wall, having a second closure plate perimeter portion so extending beyond. ### Claim 18 (depends on 1) The louvre assembly according to claim 1, wherein the continuous louvre housing perimeter wall defines a square or rectangular perimeter and comprises a bottom wall, two side walls and a top wall, each wall comprising a continuous and unapertured closure. ### Claim 19 (depends on 1) The louvre assembly according to claim 1, wherein the louvre formation comprises a plural array of louvre slats mounted within the louvre housing cavity to be arrayed successively vertically in parallel orientation such that each slat is angled acutely away from the vertical relative to the notional plane of the second open face. ### Claim 20 (depends on 1) The louvre assembly according to claim 1, provided fixed in a through opening in a closure such as a door and/or a wall of a building or housing. ### Claim 21 (depends on 1) A closure such as a door or wall, the closure comprising: a first face on a first side, a second face on a second side, and a through aperture through the first face and the second face communicating between the first side and the second side; and a louvre assembly according to claim 1 associatively mounted to the through aperture such that the louvre housing cavity is defined within the through aperture and such that the first closure plate is fixedly mounted to the first face of the closure. ### Claim 22 (depends on 21) The closure according to claim 21, wherein an apertured second closure plate is provided associatively engageable with the louvre housing to seat over the second open face of the louvre housing. ### Claim 23 (depends on 22) The closure according to claim 22, wherein the second closure plate is a discrete formation fixedly mounted to the said second face of the closure. ### Claim 24 (depends on 22) The closure according to claim 22, wherein the second closure plate is integrally formed with the second face of the closure. ### Claim 25 (depends on 17) The closure according to claim 17, wherein the closure is a security closure defining an access side and a secured side, with the baffle positioned on the secured side. ### Claim 26 (depends on 1) A door comprising: a leaf frame structure, having at least a top rail member, a bottom rail member, a hinge stile member and a lock stile member; at least one first leaf panel, mountable to a first side of the leaf frame structure; at least one second leaf panel, mountable to a second side of the leaf frame structure, that is opposite to the first side; a through aperture through the first leaf panel and the second leaf panel communicating between the first side and the second side; and a louvre assembly according to claim 1 associatively mounted to the through aperture such that the louvre housing cavity is defined within the through aperture and such that the first closure plate is fixedly mounted to the first leaf panel.
