The present invention relates to a method of treating a glazing panel from an inside location. Moreover, the present invention relates to a method of treating glazing panels used in windows and patio doors. Initially, a hole is formed on both inside and outside panes on windows and on the side and outside frames of patio doors. Next, a filter is attached to the outside pane to cover the hole whereby the filter membrane is designed to allow the passage of air and inhibit the ingress of moisture. Finally, a seal is used to cover the hole on the inside pane or to ensure that the building air does not enter the interior of the glazing panel. Where the panes are tempered glass, the hole(s) may be drilled through the frame. If necessary, one or more tubes may be inserted through the hole. Various kinds of filters are disclosed.

1. A glazing panel treatment method for either or both of removing contamination from an enclosed air space of the glazing panel and inhibiting ingress of contamination into an enclosed air space of the glazing panel, the glazing panel comprising at least an exterior pane and an interior pane and spacing and sealing means extending around and sealing the perimeters of the panes to form said enclosed air space therebetween, said method comprising the steps of: (i) creating an access hole in the interior pane from its surface furthest from the exterior pane, said access hole communicating with the air space;(ii) through the access hole, creating a vent hole in the exterior pane through which vent hole the air space communicates with ambient air;(iii) applying a filter means to the vent hole to filter air passing therethrough; and(iv) sealing the access hole; wherein the vent hole is located at a position lower than that of the access hole. 2. A method according to claim 1, wherein, prior to the step of creating the vent hole, cutting fluid is injected into the air space at least to a level to contact a cutting tool used to create the vent hole. 3. A method according to claim 1, wherein the filter means is inserted into the vent hole and retained therein by resilient engagement between the filter means periphery and the interior of the vent hole. 4. A method according to claim 3, wherein the filter means comprises magnetic material and is inserted by means of a probe having at least a tip portion that is magnetic, the filter means being attached magnetically to the magnetic tip portion which then is inserted through the access hole until the filter means is in the vent hole with its periphery engaging the interior of the hole, and the probe withdrawn, whereupon the filter means disengages from the tip portion. 5. A method according to claim 1, wherein the filter means comprises magnetic material and is inserted by means of a probe having at least a tip portion that is magnetic, the filter means being attached magnetically to the magnetic tip portion which then is inserted through the access hole until margins of the filter means adhere to the pane material surrounding the vent hole, whereupon the tip portion is withdrawn and the adhered filter means disengages from the tip portion. 6. A method according to claim 5, wherein the filter means has adhesive applied to the margins before insertion. 7. A method according to claim 5, wherein adhesive is applied to the pane material surrounding the vent hole before the filter means is inserted. 8. A method according to claim 1, wherein the step of applying the filter means comprises applying a filter means having marginal regions and a medial membranous filter screen by attaching the marginal regions to the pane material around the vent hole so that the medial membranous filter screen extends across the vent hole, said filter screen having interstices sized to permit the egress of moisture-laden air from the air space when the air space temperature and pressure are elevated relative to ambient and to inhibit ingress of moisture droplets with ambient air when the temperature and pressure of the air in the air space are less than ambient. 9. A method according to claim 1, wherein the filter means is installed bypassing the filter means through the access hole, and adhering the filter to the internal surface of the exterior pane surrounding the vent hole so that the filter means covers the vent hole. 10. A method of treating a glazing panel according to claim 1 wherein the filter means is a patch that extends across the vent hole. 11. A method of treating a sealed glazing unit installed into a surrounding frame and comprising at least an exterior pane and an interior pane and spacing and sealing means extending around and sealing the perimeters of the panes to provide an air space therebetween, the frame having a side face adjacent each pane and an edge surface generally perpendicular to the panes and directed outwardly therefrom, the method comprising the steps of: (i) creating a vent hole having a first portion and a second portion, the first portion of the vent hole extending through the frame from said edge surface and through the spacing and sealing means, said first portion of the vent hole communicating at one end with the air space, and the second portion of the vent hole extending from a said side face of the frame to communicate with the first portion of the vent hole, such that the vent hole provides air flow communication through the frame and between the air space and ambient;(ii) installing a filter means to close the second portion of the vent hole and filter air passing between the air space and ambient; and(iii) sealing the first portion of the vent hole exteriorly of the position at which it communicates with the second portion of the vent hole. 12. A method according to claim 11, for use where the spacing and sealing means comprises a tubular spacer containing desiccant, and further comprising the step of inserting a tube into the first portion of the vent hole to extend through the tubular spacer and inhibit leakage of the desiccant therefrom. 13. A method according to claim 11, for use where the frame comprises a hollow extrusion having compartments defined by structural webs, further comprising the step of inserting a tube through the frame, the tube communicating between the air space and ambient while sealing said compartments therefrom. 14. A glazing panel treatment method for either or both of removing contamination from an enclosed air space of the glazing panel and inhibiting ingress of contamination into an enclosed air space of the glazing panel, the glazing panel comprising at least an exterior pane and an interior pane and spacing and sealing means extending around and sealing the perimeters of the panes to form said enclosed air space therebetween, said method comprising the steps of: (i) creating an access hole in the interior pane from its surface furthest from the exterior pane, said access hole communicating with the air space;(ii) through the access hole, creating a vent hole in the exterior pane through which vent hole the air space communicates with ambient air;(iii) applying a filter means to the vent hole to filter air passing therethrough; and(iv) sealing the access hole; the filter means comprising magnetic material and being inserted into the vent hole by means of a probe having at least a tip portion that is magnetic, the filter means being attached magnetically to the magnetic tip portion which then is inserted through the access hole until the filter means is in the vent hole with its periphery engaging the interior of the hole, and the probe withdrawn, whereupon the filter means disengages from the tip portion and is retained in the vent hole by resilient engagement between the filter means periphery and the interior of the vent hole.
