  • Publication number: 20230142784
    Abstract: A laminated glazing for a vehicle windscreen comprising first and second sheets of glazing material joined by a sheet of adhesive interlayer material is described. The laminated glazing has an outer facing surface and an inner facing surface comprising a first treated region that has been subjected to a roughening process such that before the roughening process the first treated region has a first surface roughness and after the roughening process the first treated region has a second surface roughness. The first treated region having the second surface roughness helps the laminated glazing break when subject to an impact on the outer facing surface. Use of a roughened region to reduce the time taken for a laminated glazing to break upon being impacted by an impactor is also described.
