Glazing assemblies and method

DETAILED DESCRIPTION An aim of this invention is to overcome the before-mentioned difficulties encountered in PVB laminates and in cast-in-place laminates employing glass sheets incorporating apertures, in a simple, efficient and inexpensive manner.
According to this invention there is provided a glazing assembly comprising at least two separate sheets of glass at least one of which incorporates at least one aperture for the location of attachment means and the sheets of glass are arranged face-to-face in close substantially parallel spaced-apart relationship by means of a peripheral spacing means creating a space between the inner faces of the sheets of glass, wherein a peripheral resilient sealing means is located around the or each aperture between the opposing inner faces of the two sheets of glass and the sealing means serves to prevent a liquid resin material introduced into the space between the glass sheets from escaping into the aperture during filling of the space with the liquid resin material and also during the curing of the liquid resin material.
Preferably the resilient sealing means expands during filling and contracts during curing.
According to this invention there is also provided a method of sealing around the periphery of an aperture or apertures in a glass sheet or sheets during a cast-in-place process for laminating two or more spaced-apart glass sheets together by positioning a resilient sealing means in a space between the inner faces of the glass sheets around the periphery of the aperture or apertures to maintain a seal during filling of a space between the glass sheet or sheets with a liquid resin material and also during the curing of the liquid resin material.
Preferably the sealing means expands during filling and contracts during curing.
