Definitions

  • the invention relates to a glazing system for glass-­fronted buildings, whether private dwellings or business premises, which consists in a plurality of lights supported by a framework anchored to the permanent structure of the building; each such light comprises an internal window and an external window carried in relative frames or casements fitted to the framework, both of which open and shut. Glazing systems of this general type are widely adopted in fabricating the external walls of modern buildings, in order to let more light into the interior.
  • Such glazing systems have to satisfy a number of requirements at one and the same time; they must provide heat and sound insulation, and must prevent condensation from forming.
  • the heat and sound insulation problem is solved in part by installing double-glazing, i.e. sandwiching and hermetically sealing panes of glass in pairs such that a vacuum can be created between them.
  • this expedient is not fully effective, inasmuch as the framework which supports the single lights will be fashioned in metal (generally aluminium, in view of its good resistance to corrosion); consequently, one has areas exposed both to the internal and to the external environment at once, and a bridge is created across the thermal insulation barrier.
  • the condensation problem is tackled generally by placing hygroscopic salts in the space separating the internal and external window panes, prior to ultimate assembly.
  • a more efficient method of preventing condensation is disclosed in a former application filed by the same applicant; this consists in locating channels at the bottom of each single light, which provide a path of communication between the internal and the external environment and thus afford a degree of localized ventilation.
  • the object of the invention disclosed is to overcome those drawbacks mentioned above.
  • the stated object is realized with a glazing system as characterized by the appended claims; such a system affords a number of advantages, one of which consists essentially in the fact of eliminating the direct bridge which, in conventional glass fronts, breaks across the thermal insulation barrier between internal and external environments.
  • Another advantage of the glazing system disclosed is that of its practical design, inasmuch as access can be gained to the space existing between the internal and external windows of each light so as to enable cleaning.
  • a particularly advantageous feature of the system is that it comprises an angled hollow element fitted to the upright frame members bordering each one of the single lights, the length of which will disallow any infiltration of rainwater into the space between the internal and external window panes, regardless of wind conditions.
  • a further advantage of the glazing system disclosed is that the adhesive utilized, a type unaffected by ultraviolet radiation, remains totally shielded from the atmosphere following ultimate assembly.
  • the glass front as a whole consists in a series of single lights 1, each of which fitted to a skeleton framework 31 anchored to the permanent structure of the building.
  • Each light 1 comprises an internal window pane 24 and an external window pane 15, both of which are attached to a common frame 32; each single frame 32 is carried by the skeleton framework 31, and opens outwards by means of suitable fittings.
  • a skeleton framework 31 according to the invention is made up of T-section members denoted 2 and 3.
  • 6 and 7 denote longitudinally disposed seats located in the projecting rib 4 and transverse shoulders 5 of each T-section 2 or 3, respectively, which face outward from the building and accommodate relative seals 8 and 9; the width of the seal 8 carried by the projecting rib 4 of each T-section 2 and 3 is equal to if not greater than that of the shank of the 'T' itself, thereby concealing the projecting rib 4 completely when viewed from the front.
  • the frame 32 surrounding each of the single lights 1 is constructed from members exhibiting an elongated rectangular cross section one of which, denoted 10, takes the weight of two panes 24 and 15; the other, denoted 11, is used in conjunction with insulating panels 12 that take the place of the internal window panes 24, where appropriate.
  • each frame member 10 and 11 exhibits a longitudinal seat 13 designed to accommodate a seal 14 against which the external window pane 15 is offered flush.
  • 16 denotes an apron extending from the seat 13 of each frame member 10 and 11, which incorporates a further seat 17 for accommodation of a seal 18 that butts against the seal 8 offered by the projecting rib 4 of a relative framework member 2 or 3.
  • the frontal surfaces of the two abutting seals 8 and 18 are ridged with matching longitudinal ripples serving to enlarge the area of the interface between the two, and thus enhance its sealing action.
  • the seal denoted 18 extends outward to the point of making contact with the external pane 15; thus, the pane 15, the apron 16, and the two adjacent seals 14 and 18 combine to create a cavity for reception of the adhesive, denoted 19, by means of which each of the external panes 15 is fixed to its frame 32.
  • the adhesives generally employed are silicon compounds, unaffected by ultra-violet radiation, and the seals 14 and 18 will therefore be embodied in compatible material.
  • the frame members 10 and 11 differ in that the one exhibits a single bead 20 affording a seat 21 for the accommodation of a seal 22, the purpose of which will become clear in due course, whereas the other is provided with two smaller beads 25, occupying a similar position, which serve to hold the panel of insulating material 12 in position.
  • the internal pane 24 of each single light 1 is carried by a casement 23 constructed from hollow section 26 moulded with a slot 27 into which the pane is fitted.
  • the width of the slot 27 is such as to accommodate double-glazed panes (as illustrated), with their relative seals.
  • 28 denotes one of two coaxially disposed hinge pins that are fitted into one of the uprights 26 of the casement 23 and associate with respective angle brackets 29 by means of which the horizontal and upright members 10 of the frame 32 are fastened together.
  • the casement 23 thus is supported by the frame 32, with the hinge pins 28 positioned such that the casement 23 fits flush against the seal 22 when the internal window is shut.
  • the hollow element 30 denotes a hollow element located in one of the upright members of each frame 32, fashioned in a material compatible with the adhesive 19, which emerges into the space existing between the internal and external window panes 24 and 15 and the frame 32 carrying them.
  • a similar element 30 will be fitted to the other upright member of each frame 32, at a point diagonally opposite the element illustrated, to enhance convection of air through the interspace.
  • the hollow element 30 is angled upwards, embedded in the seals 14 and 18 and the adhesive 19, and will be of length such as to ensure that rainwater cannot penetrate to the point of reaching the interspace between the panes 24 and 15 and the frame 32, however extreme the weather conditions.
  • the outermost, bottom end of the hollow element 30 is fitted with a grille 33 designed to prevent flies and other insects from gaining the inside of the hollow element.
  • Fittings and catches for the hinged frames 32 and casements 23 will be of conventional type, and are not therefore illustrated in the drawing.
  • the objects stated at the outset are realized in full.
  • -the effectiveness of the thermal insulation barrier between internal and external environment remains unimpaired by virtue of the fact that no bridging occurs, since no metal components are exposed to the external environment once all the windows are shut;
  • -the adhesive 19 remains thoroughly protected from the atmosphere, encapsulated in a cavity formed by the two seals 14 and 18, the apron 16 of the frame member 10 or 11, and the external window pane 15;
  • -condensation is prevented from forming in the space between the external and internal panes 15 and 24 thanks to the inclusion of the hollow member 30, which not only maintains the air in the interspace at the same temperature as that of the external environment by providing a path of communication, but also, is of length such as to disallow any infiltration of rainwater, even in high winds;
  • -the space between the internal and external window panes 24 and 15 can be inspected, and thus cleaned, by reason of the fact that the internal pane 24 can be opened independently of the external pane 15.
