2.1 Laminated glass

Laminated glass is a safety glass made by laminating two or more panels of glass with a flexible plastic interlayer (PVB – Polyvinyl Butyral).                          

The glass and interlayer are bonded together by heat and pressure in a specially built autoclave. Generally the interlayer is 0.38mm thick, but other thicknesses are available to suit particular applications.

Many different laminated glass ‘make ups’ are possible with the large range of glass and interlayer types stocked, which when combined meet most

architectural glass requirements.

FEATURES AND APPLICATIONS

SAFETY – Depending on the severity of impact, glass will not splinter into jagged dangerous pieces and will remain intact in opening;

COLOUR RANGE – Wide range of colours and interlayer thicknesses including 0.38, 0.76, 1.14, and 1.52mm;

STRONGER – Heat strengthened and toughened laminated glass enabling larger panels to be glazed with greater resistance to wind-loading over ordinary annealed

glass;

CLIMATE CONTROL – Solar and thermal control functions through use of tinted and low-E glass;

SECURITY – Security features which greatly aid prevention of illegal entry and/or vandalism ;

STORM PROTECTION (weather/disaster control features) – Depending on severity of impact, glass stays intact in the opening when broken thus preventing damaging effects of weather inside building unlike ordinary annealed glass.

UV PROTECTION – Helps to protect carpets, curtains, and furniture by screening out 99% of all ultra-violet light.

FIRE PROTECTION (fire retardation) – Laminated glass though not used on its own as part of a fire resistant glazing, still provides longer evacuation time when compared to ordinary thin annealed glass;

NOISE REDUCTION – Noise reduction benefits.

DISTORTION FREE – visually distortion free in annealed form;

APPLICATIONS – suited for overhead glazing such as windows directly above doorways, rooflights, skylights and multi storey buildings, where upon impact glass is unlikely to fall to the ground below. Also suited for doors, internal partitions, side lites, lift wells, balustrading, laminated mirrors in walk through robe situations, wet areas and other areas as required.
