Prevention of Egress
The combination of an enhanced toughened glass surface bonded to an appropriate polycarbonate layer provides a composite vision panel with high resistance to manual attack (blunt blow) particularly suitable in detention centre applications.
TECDUR has now been specified and installed in a number of Prisons, Young Offenders Centres Mental Institutions and commercial projects throughout the UK.
Prevention of Ingress
The combination of float glass bonded to either side of a polycarbonate core results in a product which provides superb resistance to penetration from repeated sharp blows e.g. axe attack, particularly when compared with traditional security glasses / films.
The float glass layer generally only suffers localised damage and remains firmly bonded to the resin layer.
When combined with low iron glass - it creates an ideal solution for retail applications looking for the most visually clear security glass
Prevention of spall / damage limitation
Provision of an internal polycarbonate face to either manual attack or bullet resistance TECDUR provides a zero spall surface i.e. no glass ejected from the rear face on breakage.
This can prove particularly important for the protection of personnel e.g. bank screens, security vehicles or for the prevention of injury/self-harm in the case of severely disturbed individuals.
Bonding hard coat polycarbonate to the external face of a sealed double glazed unit provides an energy absorbing surface which reduces the risk of breakage upon impact from manual attack and/or thrown projectiles.
In addition, in the unlikely event of breakage the polycarbonate continues to provide a safe and secure façade.
The polycarbonate layer can be finished either flush to, or stepped in from, the edge of the unit. This can be beneficial when it is necessary to minimise the edge thickness of the unit due to glazing and/or thermal insulation considerations (maximisation of air space in unit).
Fail Secure’ Structural Glass Applications
Incorporation of holes in TECDUR composite panels facilitates the securing of the panel via glass fittings to either structure, or another panel.
Utilising the appropriate thickness of polycarbonate core fail secure structural glass solutions can be developed which maintain structural integrity even when the internal and external cladding glasses are broken.
