Definitions

• the present invention relates to an openable multi-pane window construction, particularly a multi-pane window of fire resistance Class F 60, the glazed framework of which includes a window frame and mutually connected window sashes, and in which construction a single pane of glass is fitted in an outer sash on the outward side of the win ⁇ dow construction, and an inner glazing unit which compri ⁇ ses at least one pane of glass is fitted in an inner win ⁇ dow sash on the inward side of the window construction.
• the invention also relates to a fixed multi-pane window construction, particularly a multi-pane window of fire resistance Class F 60, the glazed framework of which con ⁇ struction includes a window frame which has a glazing unit ' fitted therein.
• the object of the present invention is primarily to provi- de an openable multi-pane window with which the window frame and at least the inner sash are made of wood, and which can resist a "standardized" fire for at least a period of one hour (i.e. fulfills the requirement of fire resistance Class F 60), so that the window construction will fulfill the same fire resistance requirements as those fulfilled by the walls of the building in which the window construction is installed.
• standardized fire is meant here a carefully specified artificial fire created by means of oil burners, in an accurately specified test room in a wall of which the win ⁇ dow construction in question is installed.
• the artificial fire is specified primarily with regard to the rise in room temperature as a function of the time over which the fire has continued.
• the temperature increa ⁇ ses by ca 550°C during the first five minutes passes 650°C after ca 10 minutes, 700°C after ca 13 minutes, 800°C after ca 26 minutes, and 900°C after ca 50 minu ⁇ tes, and reaches a temperature somewhat higher than 920°C after 60 minutes.
• a window construc ⁇ tion of the aforedescribed kind in that the window frame and the inner sash are made of wood, there being mounted in the inner sash a metallic clamping frame in which the inner glazing unit is firmly clamped along the edges thereof through an adjustable clamping force; both the single pane of glass and a glass pane ⁇ of the inner glazing unit are made of plain, heat hardened borosilicate-fire p resistive glass, such as Pyran glass ; the outer sash consists of a metal frame in spaced relationship with and located outwardly of the wooden inner sash; and the freely exposed surfaces of at least the wooden window frame and the wooden inner sash on the inward side of the construc- tion are provided with a coating of fire resistive paint.
• the glazing unit on the inward side of the window con ⁇ struction may comprise a sealed glazing unit which, in addition to the pane of borosilicate-fire resistive glass also includes a pane of conventional window glass which is located on the inward side of the unit in spaced relation ⁇ ship with the pane of fire resistive glass.
• the glazing unit may include on the inward side of the construction solely a single glass pane which is made of plain, i.e. non-reinforced, heat hardened boro ⁇ silicate-fire resistive glass and which is laminated with, e.g., a sheet of low emissive glass.
• the inventive window construction is thus a multi-pane window, preferably a three-pane window, which incorporates a pane of plain, heat hardened borosilicate-fire resistive glass on both the outside of the construction and on the inside of the glazing unit.
• the inventive window construction is also imparted fire resis ⁇ tive qualities by the metallic clamping frame and by the fire resistive paint applied to the wooden window frame and to the wooden inner sash on the inward side of the construction.
• elevated temperatures for instance temperatures of 150°C - 170°C
• the fire resistive paint swells in the manner of a "souffle" there- with forming a heat insulating layer which protects the underlying wood.
• the fire resistive properties of the window construction can be further enhanced with the aid of fire-swelling strips and jointing compounds and non-combustible seals in the construction.
• Such further developments of the inven ⁇ tion are set forth in particular in claims 4 and 6.
• a suitable construction of the metallic,clamping frame is specified in particular in- claims 5 and 6.
• the window con- struction according to the invention can also include a wooden, intermediate sash, as set forth in claim 7.
• the window construction may conveniently include means which provide a connection which will hold - the sashes in the window frame when the normal sash retai ⁇ ning function of the hinges ceases. This can be achieved, for example, in accordance with the arrangements defined in Claims 8 and 10 respectively.
• the fire resistive properties of the window construction can be further enhanced by suitable selection of material dimensions, in accordance with Claim 9.
• the concept of the invention is not restricted solely to openable window constructions in accordance with Claims 1-10, but can also be applied to a fixed multi-pane window construction according to Claim 11.
• the present invention affords, with the aid of simple means, window constructions of fire resistance class F 60 which exhibit extremely good properties with regard to imperviousness, k-values and mechanical strength.
