Semi-tempered Glass

One of the safety glass types offered by GlasAktiv is semi-tempered glass in accordance with DIN EN 1863. Semi-tempered glass is a form of heat-strengthened safety glass. The thermal prestressing is less intense than with toughened safety glass and hence semi-tempered glass exhibits different fracture behaviour. Semi-tempered glass is harder that normal float glass and breaks with long straight cracks which extend from the stress point to the edge of the glass pane.

Semi-tempered glass is most commonly used in overhead glazing and processed into laminated glass
