A fire resistant vacuum insulating glazing assembly includes at least one vacuum insulating glazing unit that has a first glass pane, GP1, which includes an inner pane face and an outer pane face and a second glass pane, GP2, which includes an inner pane face and an outer pane face. A set of discrete pillars is positioned between the first and second glass panes and maintains a distance between the first and the second glass panes. A hermetically bonding seal seals the distance between the first and second glass panes over a perimeter. An internal volume, V, is defined by the first and second glass panes and is closed by the hermetically bonding seal. There is a vacuum of absolute pressure of less than 0.1 mbar and the inner pane faces face the internal volume, V.

The inner pane faces face the internal volume, and the glazing assembly further includes at least one intumescent unit having a layer of intumescent material, an intumescent unit glass pane, and an intumescent unit peripheral spacer. The intumescent unit glass pane and the intumescent unit peripheral spacer define an intumescent unit volume, and the layer of intumescent material and the intumescent unit peripheral spacer face one of the outer pane faces of the first or second glass panes.

Fire resistant glazings comprise a fire resistant interlayer based upon a silicate waterglass are characterized by the incorporation of aluminum ions. The aluminate is incorporated as a solution which has been partially neutralized using hydroxycarboxylic acid which is preferably citric acid. The incorporation of aluminum provides glazings have improved fire resistance and impact properties.

A light-permeable heat protection element having a first and a second support member and having an intermediate layer between the first and the second support member. The intermediate layer has a cured alkali silicate gel formed of an aqueous alkali silicate solution and a silicon dioxide compound. The alkali silicate gel of the intermediate layer thereby has a molar ratio of silicon dioxide (SiO.sub.2 to alkali metal oxide (M.sub.2O) greater than 4. Furthermore, the alkali silicate gel has 0.05 to 0.14 weight percent of lithium silicate.

A fire-resistant glazing unit includes a first untempered glass sheet, a second untempered glass sheet and a solid interlayer stack, wherein the interlayer stack includes a first intumescent layer, an essentially inorganic layer and a second intumescent layer.

A single and multi-layer flat glass-sensor structure and method of making the flat glass-sensor structure. The flat glass sensor structure comprises at least one flat glass layer, a sensor and a heater. The flat glass layer has a plurality of cutouts that are configured to “suspend” the sensor on top of or in plane with the flat glass layer. The sensor is an electrochemical wafer with at least one sensory element and flat glass connectors. Each flat glass connector is in minimal contact with at least one sensory sub-area. The heater is a resistive heating element that is on top of or in plane with the flat glass layer configured to heat the sensor. The flat glass connectors are configured to provide support for electrical leads to the heater and membrane. The flat glass connectors are also configured to provide temperature insulation of the suspended sensor.

A transparent, shatterproof, bullet-resistant glazing with fire protection properties, consisting of a ballistic block constructed from at least two transparent panes adherently bonded to one another by at least one transparent, adhesion-promoting layer, wherein each pane has a thickness of at least 3 mm, a fire protection unit constructed from at least two transparent panes adherently bonded by a transparent, intumescent layer, and at least one spacer between the fire protection unit and the ballistic block, the surfaces of the unit and the block being arranged parallel or substantially parallel to one another such that a hollow space is situated therebetween.

Fire protection glazing made of two or more glass panes spaced apart from each other by a spacer. A fire protection material and the spacer are arranged in an intermediate space between the two glass panes. A secondary seal encloses the fire protection material and the spacer in the intermediate space. The secondary seal has a intumescent fire protection property. Exclusively the fire protection material, the spacer, optionally having an optional spacer attachment for attaching the spacer to the glass pane, and the secondary seal can be arranged in the intermediate space between the two glass panes.

A method for the deposition of an organic intumescent coating on a glass sheet, includes the preparation of an organic intumescent coating composition by mixing a latex having a pH from 4 to 6 and an intumescent agent chosen from thermally degradable polycarboxylic acids, and the application of the organic intumescent coating composition to the glass sheet.

The invention relates to aqueous silica dispersion with a pH in the range from 8 to 14, comprising a base chosen from the group consisting of alkali metal hydroxides, (akyl)ammonium hydroxides or a mixture thereof, at least 35% by weight of silica particles surface-treated with an amino-organosilane (I) and/or a product of hydrolysis of compound of formula (I), 3% to 35% by weight of at least one polyol, 20% to 60% by weight of water, preparation of such dispersion and the use thereof in fire-resistant glass.
