A multiple glazing unit is described comprising two vitreous material sheets (10, 12) positioned in face-to-face spaced apart relationship, having a gas space (14) there-between delimited by a peripherally extending spacer (16). Layers of sealant (26, 28) are positioned between the spacer (16) and each of the sheets (10, 12). A cordon or cordons of resin (30) are positioned in contact the layers of sealant (26, 28) and extending between the spacer (16) and each of the sheets (10, 12). At least part of each face of the spacer (16) in contact with the sealant (26, 28) extends obliquely with respect to the inner surface (32, 34) of the adjacent sheet. The layers of sealant (26, 28) thereby extend progressively from a region (40) of minimum thickness to a region (42) ofmaximum thickness. The resin (30) is in contact with the sealant (26, 28) substantially in the region (42) 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°. The penetration of water into the interior of the unit is reduced by this construction, significantly improving the life expectancy thereof.
