<p>An intrusion resistant laminated glazing (1), suitable for automotive use, comprises an impact resistant ply of rigid thermoplastic polyurethane (2) sensitive to ultra-violet radiation and, outside said ply, an ultra-violet absorbing or reflecting ply. The ultra-violet absorbing ply may be of thermoplastic polyurethane interlayer material (5, 6) which serves to bond the rigid thermoplastic polyurethane ply (5, 6) to outer glass plies. By using interlayer materials of low modulus to bond the rigid thermoplastic ply to outer glass plies, a product with good impact resistance and intrusion resistance is achieved.</p> |
