FLAME-RESISTING GLAZING PANELS

摘要

IMPROVEMENTS IN FLAME-RESISTING GLAZING PANELS The flame-resisting glazing panel comprises at least one flameresisting glazing 1 and at least one mechanically strong glazing 2 which is spaced from the flame-resisting glazing by a layer of gas 3. The mechanically strong glazing 2 has an aperture 8 through which extends a plug 9-11; 14-16; 18-22; 26-31 which is arranged hermetically and seals the aperture. The plug is made from a material which is fusible at a relatively low temperature of 70.degree. to 150.degree.C.
