spontaneous glass breakage
solutions for nickel sulphide inclusions and unexpected glass failure.
toughened glass can shatter without warning. this phenomenon, often caused by impurities known as nickel sulphide inclusions, can lead to sudden fracture and granulation—posing a major hazard to pedestrians and occupants.
the risk
impurities within the glass react to changing weather or temperature conditions, resulting in sudden fracture. toughened glass granulates into thousands of tiny pieces that can fall from height.
the solution
high-grade safety containment films render glass safe in the event of breakage. when combined with edge retention, the entire panel is held securely in the frame.
glass containment & edge retention
safety film alone holds shattered glass together. edge retention takes this further by securing the edges of the film to the window frame, ensuring that the entire panel stays in place even if fully granulated.

attachment methods
structural silicone: high-grade silicone fillet applied between the film and the frame.
mechanical attachment: aluminium angle beading, powder-coated to match your frame colour.
case study: manchester crown court
the atrium at manchester's crown court was at risk due to suspected nickel sulphide inclusions in its toughened glazing. any breakage could have fallen onto pedestrians below.
lustalux provided a 200-micron clear safety film followed by a secure powder-coated aluminium attachment system. the work was carried out out-of-hours to ensure zero disruption to court operations.
