Problems solved by technology

However, we have found that such protective additional layers as described in GB 2,293,179, when deposited on certain coating stacks, for example deposited on "essentially composed of at least one selected from the group consisting of titanium, titanium oxide and nitride Titanium material composed of base anti-reflective layer / infrared reflective layer / top anti-reflective layer / top coat" type coating stack does not always provide good resistance during transportation, and in the coating Scratches may appear on the surface

Abstract

A glazing panel has a coating stack comprising in sequence at least a base antireflective layer, an infra-red reflecting layer, a top antireflective layer and a top coat layer comprising in sequence at least two sublayers: a first one consisting essentially of at least one material selected from the group consisting of titanium, titanium oxide and titanium nitride, and a second one, consisting essentially of silicon oxide, silicon nitride, silicon oxynitride, silicon carbide, silicon carbonitride, silicon oxycarbide, or silicon oxycarbonitride. The second topcoat sublayer may have a geometrical thickness in the ranges 15 to 30 AA or 200 to 400 AA.

Description

technical field The present invention relates to glass panes and in particular but not exclusively to solar control and / or low emissivity glass panes and / or glass panes which can be subjected to heat treatment after application of optical filters in the form of a coating stack to a glass substrate. The invention relates more particularly to the case where the coating stack is applied to glass by vacuum deposition techniques, for example by sputtering or magnetron sputtering. Background technique When designing a coating stack for glass applications, several factors must be considered. These factors include not only the desired light-energy properties of the coated glass sheet, but also, for example, the abrasion resistance of the coating stack (for ease of handling, shipping and processing), the stability and chemical durability of the coating stack (to facilitate storage under various conditions) and tolerances for manufacturing process control (to facilitate acceptable p...
