ABSTRACT:
A method of laminating glass sheets, the method comprising the steps of: (a) providing a glass sheet assembly comprising a pair of opposed glass sheets which are spaced from each other and spacer means located between the glass sheets, the spacer means being air permeable and liquid impermeable and extending along peripheral edges of the glass sheets, the glass sheet assembly being in a substantially horizontal orientation; (b) introducing a measured volume of a liquid laminating resin between the glass sheets so that the resin contacts the inner surfaces of both the top and bottom glass sheets as it is introduced into the space between the sheets, the introduction of resin being controlled so that a resin meniscus between the top and bottom sheets spreads outwardly in a controlled manner; (c) filling the space between the glass sheets with the measured volume of resin, air which is displaced by the resin being evacuated through the spacer means; and (d) permitting the resin to cure and solidify thereby to form an interlayer between the glass sheets. The invention also provides a laminated glass article comprising a pair of opposed glass sheets which are separated by an interlayer of a cast-in-place laminating material composed of a cured plastics resin, the resin having been introduced between the sheets as a liquid having a viscosity of from 200 to 4000 centipoise, and an air permeable and liquid impermeable spacer means extending around the periphery of the article between the glass sheets.
