Pilkington Group Ltd | Date: 2017-05-10

Methods are disclosed for planarisation of a coated glass substrate by deposition of a silazane based layer thereon. Coated substrates according to the invention exhibit improved properties in terms of reduced roughness, lower haze and higher visible light transmission and the coated surface may be exposed to the external environment, for example as surface 1 or surface 4 of a double glazing unit. The resulting smooth surface is less susceptible to marking and scratch damage, and offers enhanced surface energy (improved hydrophobicity).

Methods of making a laminated glazing having reduced optical distortion when installed in a vehicle are described. The laminated glazing has first and second sheets of glazing material each separately shaped between a pair of shaping members that are then laminated together. The position for bending the first sheet of glazing material may be deliberately offset from the position for bending the second sheet of glazing material. During the lamination step, the first sheet of glazing material may be displaced relative to the second sheet of glazing material by a lateral and/or longitudinal positional displacement. The first and/or second sheet of glazing material may have been cut such that after lamination at least a portion of the peripheral edges thereof are aligned. Apparatus for shaping a sheet of glazing material for carrying out the aforementioned methods is also described, as is a resulting laminated glazing.

Solar collector apparatus is described in which solar radiation is collected in a glazed cavity which may also include a transpired solar collector layer. Air warmed in the cavity may be used for space heating within buildings or diverted to heat management systems which facilitate, for example, heat storage. The glazing, particularly coated glazings, improve the performance of the devices by allowing solar energy to enter the cavity and preventing heat loss, and by negating the effect of ambient wind on the transpired solar collector layer.

A glazing comprising a transparent substrate, a plurality of electrically conductive filaments extending over the transparent substrate, wherein the filaments are shaped into a sequence of portions of the perimeters of ellipses, wherein ellipse axial ratios of the ellipses are in the range 1.1 to 4.0 and are selected so that from a pre-defined viewing position and in corresponding pre-defined viewing directions the ellipses in the plane of substrate are viewed as circles. In a preferred embodiment, major axis angles are selected so that from a pre-defined viewing position and in corresponding pre- defined viewing directions the ellipses in the plane of substrate are viewed as circles. In an example of a heated vehicle window, diffraction patterns caused by oncoming headlights interacting with heating filaments of a vehicle window are thereby minimised.
