Insulating Glass Units
Safety & Protection
Safety insulating glass units can be made up from laminated or tempered glasses or both types in one insulating glass unit. It depends on the situation witch glass type to use as they have different properties.
Laminated glass units
Laminated glass provides structurally safer, stronger glass panel that if broken, holds glass fragments together.
ALTEHS uses PVB (polyvinyl butyrain) interlayered glass when producing safety insulating glass units. This is a quality architectural and security glass option with increased strength for use in commercial and domestic installations.
Generally glazing less than 800mm from floor level
Possible PVB specifications:
0.38 mm - laminated glass
0.76 mm - safety glass P4A
1.52 mm - burglary glass
Degradation from UV light is significantly reduced with the use of thicker lamination layers.
Recommended for safe glass in public buildings, windows, doors, roof glass, shop fronts, safe for burglars
Specifications:
Standard: EN12543
Max size: 2500*3700mm
Min size: 100*250mm
Thickness: 4-20mm
Tempered glass units
Tempered glass is treated so it can withstand greater temperatures, impact and stress, but if broken splits in small pieces doing no or limited harm to person impacted.
Generally glazing less than 800mm from floor level
In some cases also Heat Strenghtened glass can be used instead of Tempered glass.
Heat soak testing option should be considered when choosing tempered glass.
Recommended for safe windows, doors, balconies, shopfronts, roof glass
Specifications:
Standard: EN12150
Max size: 2200*4200mm
Min size: 100*250mm
Thickness: 4-19mm
