Definitions

  • the present invention relates generally to multiple-glazed window units and more particularly, to multiple-glazed units having their insulating air space in fluid communication with the atmosphere external to the unit.
  • Multiple-glazed, insulating window units usually consist of two (or more) panes of glass maintained in spaced, parallel relation to each other by a spacing and sealing assembly which is structurally bonded to the marginal edge periphery of the opposed, inner or facing surfaces of the glass panes to define an insulating airspace between the panes.
  • the spacing and sealing assembly generally hermetically seals the airspace from the environment.
  • the spacing and sealing assembly generally contains a desiccant material or dehydrator agent adapted to adsorb moisture or water vapor which may be present in the airspace when the glass panes are assembled or which may later form by condensation within the airspace, to ensure dryness of the airspace to prolong the useful life of the unit and to enhance the performance quality thereof.
  • sealed, insulating window units of the above-discussed type are frequently subjected to deflection of the glass panes due to pressure differential between the air space and the exterior atmosphere.
  • the pressure differential may be caused in a multiplicity of ways. One cause is by the atmospheric pressure whereat the window unit is installed being different than the pressure conditions which existed when the unit was sealed.
  • the pressure differential can also be caused by large temperature differences between the air space and the exterior atmosphere, e.g. during large atmospheric temperature changes. Large atmospheric pressure changes may also cause this pressure differential.
  • the pressure between the panes is less than the exterior pressure, the panes are forced closer together. Conversely, when the pressure in the space exceeds the exterior pressure, the panes are forced apart.
  • Appreciable deflection of the panes can cause optical distortion of the window unit and can also present an undesirable cosmetic effect. Further, deflection places stress on the spacing and sealing assembly which gradually weakens the adhesive bond between the glass surfaces and the spacing and sealing assembly. This phenomenon may result in leakage and infiltration of relatively moist exterior air into the insulating air space, ultimately causing satiation and exhaustion of the desiccant contained by the spacer element. When the desiccant is exhausted, it is no longer capable of adsorbing the moisture-vapor present in the air space, and condensation of the moisture-vapor begins to occur on the glass surfaces contacting the air space (i.e. interior glass surfaces). More specifically, the moisture-vapor forms a molecular film of water on the interior glass surfaces. The molecular film absorbs or leaches molecules or ions from the glass surfaces. This leaching phenomenon is evident/is manifested as scum or stain on the interior glass surfaces, which imparts an undesirable white hazy or foggy appearance to the window unit.
  • a multiple-glazed unit is constructed comprising a plurality of glass sheets separated at their marginal edges by a hollow spacer element containing a desiccant material, an elongated strip of mastic in sealing contact with the edges of the glass sheets and the spacer element and a pressure sensitive tape covering the strip of mastic.
  • the unit is provided with an aperture or aligned opening through the tape, mastic and outer wall of the spacer element, to connect the atmosphere with the desiccant and at least one other opening through the inner wall of the spacer element communicating with the insulating air space of the unit.
  • the aligned openings or apertures permit the unit to "breathe" through the desiccant material in response to changes in atmospheric conditions.
  • U.S. Patent No. 3,771,276, also assigned to the assignee of the present invention teaches a multiple-glazed unit having a breather device comprised of a capillary tube connected to a column of desiccant, so that a free end of the capillary tube is disposed in open communication with the air surrounding the unit (i.e.
  • the breather unit works in the following manner.
  • the exterior atmospheric pressure exceeds the air pressure of the insulating air space, e.g. due to a nighttime temperature drop, then air flows from the exterior atmosphere, through the capillary tube and the desiccant column, and thenceforth, into the insulating air space.
  • moisture contained in the entering air is adsorbed by the desiccant.
  • the air space pressure and the exterior atmospheric pressure are equalized, thereby preventing deflection of the opposed glass panes.
  • the present invention in one embodiment, comprises a window unit having two (or more) sheets, e.g. glass panes, maintained in spaced relationship to each other by a spacing and sealing assembly bonded to the marginal edge periphery of the inner facing surfaces of the panes, to define an insulating air space therebetween.
  • the spacing and sealing assembly or "edge packing” preferably contains no desiccant or adsorbent material, thereby reducing the costs of fabricating or manufacturing the window unit.
  • opposed portions of the spacing and sealing assembly are each provided with at least one and preferably at least two breather holes, to put the insulating air space in fluid communication with the atmosphere outside of the window unit.
  • the breather holes are positioned to enable free, unobstructed, unimpeded movement of outside air and water vapor molecules through the breather holes of one assembly portion, through the insulating air space and thenceforth through the breather holes of the opposed assembly portion, and back into the outside atmosphere, to thereby provide a continuous moisture-vapor transmission path from the outside atmosphere, through the insulating air space, and back to the outside atmosphere.
  • a filtering medium preferably covers the breather holes to filter out dust, dirt, liquids, and other contaminants, to prevent their ingress or migration into the insulating air space.
  • the breather holes function to allow rapid equalization of the pressure of the atmosphere within the insulating air space and the atmospheric pressure outside of the window unit, to prevent or minimize deflection or bowing of the glass panes.
  • free circulation or movement of outside air and water vapor molecules into and out of the insulating air space minimizes the trapping of these molecules within the air space and thereby minimizes condensation and/or moisture buildup within the air space, even during periods of drastic or unusual changes of temperature and/or relative humidity conditions in the outside atmosphere.
  • the present invention also contemplates a frame means or sash for retaining the window unit within a window opening provided in a structure.
  • the sash has a glazing pocket or recess for receiving the marginal edges of the multiple-glazed window unit. Portions of the sash which correspond to the portions of the edge packing provided with the breather holes, are spaced from the outer surface of the corresponding portion of the edge packing, to form an air passageway channel or chamber therebetween. At least one hole is provided through the sash portions corresponding to the portions of the edge packing having the breather holes, to put the insulating airspace in communication with the atmosphere external to the window unit, via the air passageway channels, to thereby establish a continuous transmission path for free air and water vapor molecular flow through the insulating air space.
  • the present invention also encompasses means associated with the atmosphere communicating holes for filtering dust, dirt, liquids and the like to prevent or minimize their ingress or migration into the air passageway chambers.
  • a multiple-glazed window unit 20 having a pair of sheets 22, 24 maintained in spaced relation to each other by a spacer and sealant assembly 26 defining an insulating air space 28 between the sheets 22, 24.
  • the type of sheets 22, 24 employed is not limiting to the invention.
  • the sheets 22, 24 are transparent sheets made of, e.g., glass or plastic.
  • either or both of the sheets 22, 24 may be rendered opaque by a suitable opacifier, e.g. such as taught in U.S. Patent No. 4,000,593 issued to Cypher, which teachings are herein incorporated by reference, to thereby provide a spandrel unit.
  • the sheets 22, 24 may have any desired optical, thermal, safety, aesthetic, or solar control properties.
  • either or both of the sheets 22, 24 may be tinted or colored glass, e.g. such as the glass sold by PPG Industries, Inc. under their registered trademarks SOLARBRONZE@, SOLARGRAY@, or SOLEX®.
  • either or both of the sheets 22, 24 may be coated as taught in U.S. Patent No. 4,000,593, which teachings are herein incorporated by reference, such as with metallic or metallic oxide reflective films or coatings, e.g. such as the type of coatings applied to multi-glazed units sold by PPG Industries, Inc. under their registered trademarks NESA®, SOLARBAN 560-14@, or SOLARBAN 570-30@.
  • either or both of the glass sheets 22, 24 may be laminated, heat strengthened, or tempered for safety or other purposes.
  • spacer and sealant assembly employed in the practice of this invention is also not limiting to the invention. Any convenient type of metal or non-metal spacer-sealant assembly may be used in the practice of this invention.
  • Suitable metal spacer-sealant assemblies which may be used in the practice of this invention include, but are not limited to, those taught in U.S. Patent Nos. 2,306,327; 2,838,810; 2,684,266; 3,280,523; and 3,919,023, all of which are assigned to the assignee of this invention, which teachings are all herein incorporated by reference.
  • Suitable non-metal spacer-sealant assemblies which may be used in the practice of this invention include, e.g., those taught in U.S.
  • Patent Nos. 3,669,785; 4,109,431; and 4,215,164 which are assigned to the assignee of the present invention, and in U.S. Patent Nos. 4,198,254; 4,205,104; and 4,226,063, which teachings are also herein incorporated by reference.
  • a preferred embodiment of the present invention comprises a pair of transparent glass sheets 22, 24 held in spaced relation to each other by a hollow, metal spacer 30 made of extruded aluminum, steel or any other suitable material, extending around the inner, marginal peripheries of the glass sheets 22, 24.
  • a moisture-resistant mastic layer 32 e.g. such as the type taught in U.S. Patent No. 3,791,910 issued to Bowser, which teachings are herein incorporated by reference, adheres the spacer 30 to the glass sheets 22, 24, to thereby form the enclosed chamber or insulating air space 28.
  • no desiccant or absorbent material is put into the hollow interior of the spacer 30, to thereby reduce manufacturing costs and complexity.
  • a fine mesh screen e.g. a cloth, fabric, or stainless steel screen 40 having an adhesive applied to at least one side thereof, is applicated to the outer periphery of the spacer 30.
  • the fine mesh screen 40 may suitably be a venting tape of the type sold by 3M Company.
  • a ribbon or layer 34 of adhesive sealant material is preferably adhered to the outer periphery of the venting tape 40 and the inner marginal peripheries of the glass sheets 22, 24.
  • the outer, sealant layer 34 may suitably be of the type taught in U.S. Patent Nos. 4,348,435; 2,306,327; or 3,791,910.
  • the outer sealant layer 34 should form a resilient, firm, adhesive structural bond to maintain the desired spacing between the sheets 22, 24.
  • the inner, mastic layer 32 and the spacer 30 preferably provide a primary hermetic seal and the outer, sealant layer 34 preferably provides a secondary hermetic seal, to minimize migration or penetration of moisture or water vapor into the insulating air space 28. Thereafter, a channel member (not shown), such as disclosed in U.S. Patent Nos.
  • 2,838,810; 2,964,809; and 3,280,523, can be affixed around the periphery of the unit 20 to protect the edge periphery of the sealant layer 34.
  • a durable material e.g. polyethylene tape 44 is applied around the outer periphery of the sealant layer 34 and the peripheral edges of the glass sheets 22, 24 to protect the same.
  • aligned openings 42 are provided through the protective tape 44, the sealant layer 34, the venting tape 40, and the front wall 46 and the back wall 48 of the spacer 30, to thereby put the insulating air space 28 in direct communication with the ambient atmosphere surrounding the window unit 20.
  • the openings 42 preferably comprise breather holes 42 located at opposite corner portions of the vertical legs 5& of the spacer and sealant assembly 26.
  • the breather holes 42 are located at opposite corner portions of the horizontal legs 52 of the spacer and sealant assembly 26.
  • the openings 42 comprise a breather hole 42 at a central portion, e.g.
  • the openings 42 are not limiting to the present invention.
  • the openings 42 may suitably be, e.g., slits, slots, apertures, or holes of any shape, e.g. oval, circular, elliptical, triangular, rectangular, polygonal, etc.
  • the openings 42 may comprise slots (not shown) provided through the four corners of the spacer and sealant assembly 26.
  • the only criterion for the size, shape, and location of the openings 42 is that they collectively or cooperatively function to provide a direct moisture-vapor molecular transmission path from the ambient atmosphere, through the insulating air space 28, and back to the ambient atmosphere.
  • This free, circulatory flow or movement of water vapor molecules into and out of the air space 28 prevents or minimizes condensation on the glass sheets 22, 24 by minimizing the trapping of these molecules within the air space 28. Further, this free movement of air and water vapor molecules into and out of the air space 28 enables rapid equalization of the pressure and relative humidity between the air space 28 and the ambient atmosphere.
  • Rapid equalization of the pressure in the air space 28 with the pressure of the ambient atmosphere minimizes the edge stresses imposed on the spacer and sealant assembly 26 by deflection of the glass sheets 22, 24 due to pressure differences between the air space 28 and the ambient atmosphere. Rapid equalization of the relative humidity in the air space 28 with the relative humidity of the ambient atmosphere minimizes condensation in the air space 28 due to fluctuations of atmospheric humidity conditions. It is believed, based on testing of window units made in accordance with the teachings of this invention, that maximum free movement of air and water vapor molecules through the air space 28 occurs when the breather holes 42 are located substantially directly opposite each other.

  • a resilient e.g.
  • the base 70 of the glazing pockets 68 of at least the vertical sash members 66 are spaced from the outer surface of the corresponding vertical legs 50 of the spacer and sealant assembly 26 of the window unit 20, to provide a longitudinally extending vertical air passageway channel or chamber 72 between the base 70 of the glazing pockets 68 of the vertical sash members 66 and the outer surface of the corresponding vertical legs 50 of the spacer and sealant assembly 26.
  • one or more openings 74 are provided through the outer face or wall 76 of the vertical sash members 66 to put the chambers 72 in direct communication with the ambient atmosphere around the composite window and sash 62.

  • the openings 74 may suitably be, e.g. slits, slots, apertures, or holes of any shape, e.g. oval, circular, elliptical, triangular, rectangular, polygonal, etc.
  • the openings 74 are preferably shielded from the external environment by means of a suitable water or weather barrier means, e.g. generally arcuate or canopy-shaped members (not shown) which are conveniently attached, e.g. mechanically fastened or welded, to the outer face or wall of the sash members 64 and/or 66 with which the openings 74 are associated.
