Saftey+Plus

Safety+Plus toughened glass is up to four or five times as strong as ordinary flat glass. It will withstand the sudden shock of hot dishes placed on the surface. Safety+Plus retains all the good qualities of ordinary glass, coming in a range of thicknesses.  If it does break, the whole pane of Safety+Plus shatters into small, blunt granules less than 1cm across which don’t cause the horrendous cuts and slicing of normal glass.

 Toughened glass can be a designer item. Printing on Safety+Plus adds a designer finish with patterns for shower modesty panels, borders around a window or graphic designs on the glass.

Safety+Plus is the choice for doors, shop fronts and all floor to ceiling glazing.

 Use Safety+Plus toughened glass in these risk areas:

  • Along passageways
  • High foot-traffic zones
  • Doors and nearby panels
  • Shower and bath enclosures
  • Balconies
  • Stairs and balustrades
  • Furniture
  • Shop fronts
  • Floor-to-ceiling glass walls

It’s the surface compression, which extends to about 20% of the glass thickness, which provides the safety strength. When the surface is penetrated, the glass breaks into small particles. 

For this reason Safety+Plus toughened glass can’t be cut or drilled. All shaping of the glass is done before it’s toughened.

 Safety+Plus can be used from 280°C to 70°C, withstanding heat shocks of approximately 200°C.

 By comparison with 280°C temperatures, ordinary glass breaks at about 50°C - 60°C. It’s most important Safety+Plus is not fitted in direct contact with other glass or metal - rubber or plastic washers are required.

 Safety+Plus toughened glass gains strength from surface compression. When that’s pierced the glass shatters into small particles, avoiding dangerous flesh-piercing shards.

 Laminated glass has two or more sheets of annealed glass plus a flexible interlayer of PVB (poly vinyl butyral), bonded together by heat and pressure.

 The interlayer means the glass won’t disintegrate when broken, and it provides a better barrier against penetration.

 Laminated glass offers options for noise control, fade resistance and other specialist uses.

 We specify acoustic laminate when sound reduction is really important. It uses a special noise suppressing PVB inner layer between the laminated sheets of glass, a viscoelastic compound which actually dampens the vibration effect of the sound waves.

 Special laminated glass is also used in some fire risk situations. As it resists heat more effectively than ordinary sheet glass, laminate can confine a fire to one area and allow time to raise an alarm. In more extreme situations we specify fire rated glass.

 Tougher by design

Safety+Plus thermally toughened glass is manufactured in accordance with these standards licensed by Standards New Zealand:

  • AS/NZS2208 Safety glass for use in buildings
  • NZS7841 Glass components for domestic appliances
  • AS/NZS2080 Safety glass for land vehicles
  • NZS5238 Specification for Ships' Windows (BS MA 25)

 Safety+Plus is produced in a highly specialised toughening plant, a state of the art American Tamglass BHF electric furnace within GlassTech’s manufacturing plant.

Marine Toughened Glass

Marine glass, which must meet exacting specifications, is produced in the GlassTech factory. 

Glass Tech’s Safety+Plus flat toughened glass is approved for recreational vessels and those built to survey standard; owners and builders of all classes of vessels can discuss their needs with our specialists team.

Glass for recreational vessels can be supplied in a variety of thicknesses using processes developed at GlassTech. 

New Zealand Standard NZS 5238 covers the survey requirements for marine toughened glass from 10mm to 19mm thick. The New Zealand Standard has evolved from the British Standard BS MA 25 by adoption. 

Full computer control of the furnace settings and operating parameters ensure consistent product standards. Energy conservation in this latest generation furnace is a high priority in today’s environment. 

Moving horizontally through the oven, the glass sheet is heated to a plastic state around 650oC. Ceramic rollers regulate its speed to minimise any optical distortions. 

Released from the oven at a precise moment controlled by the computer, the glass is rapidly cooled by a series of high velocity air nozzles, putting the surface into compression while the core remains in tension.  

It’s the surface compression, which extends to about 20% of the glass thickness, which provides the safety strength. When the surface is penetrated, the glass breaks into small particles. 

For this reason Safety+Plus toughened glass can’t be cut or drilled. All shaping of the glass is done before it’s toughened.
