A multiple glazing unit comprising two vitreous material sheets positioned in a face-to-face spaced apart relationship, and having a gas space there-between delimited by a peripherally extending spacer. Layers of sealant are positioned between the spacer and each of the sheets. A cordon or cordons of resin are positioned in contact the layers of sealant and extending between the spacer and each of the sheets. At least part of each face of the spacer in contact with the sealant extends obliquely with respect to the inner surface of the adjacent sheet. The layers of sealant extend progressively from a region of minimum thickness to a region of maximum thickness. The resin is in contact with the sealant substantially in the region of maximum thickness. The spacer has a cross-section which is open to the gas space and/or the oblique faces of the spacer extend at an angle of at least 9.1 DEG . The penetration of water into the interior of the unit is reduced by the above construction, significantly improving the life expectancy the above glazing unit. |
