SLUMPED GLASS PRODUCT INFORMATION

PRODUCT INFORMATION FOR SLUMPED GLASS

Textured slumped glass combines organic and directional elements for a unique design. Ideal for divider walls or partitions, it offers a beautiful decorative finish while providing privacy for corporate spaces.

Slumped glass panels can be finished in any colour of your choice. They can be used as cladding or facades to cover other wall surfaces, making them perfect for hotel and corporate entrances.

The glass can be manufactured in various thicknesses (6, 10, 12, 15, and 19mm) in clear or low iron glass, as well as toughened (tempered) or annealed safety glass. Panels can be produced up to 1250mm x 3200mm in size and are available in clear, low iron, rich tinted glass, or vibrant painted colours.

With its non-porous, maintenance-free surface, our slumped glass remains bright, new, and clean for a long time without requiring additional maintenance.

PANEL SIZES

Maximum single panel size: 3200x1250mm (6 & 8mm) 3100x1200mm (10 & 12mm)
Smaller custom sizes available and minimum charges apply.

GLASS THICKNESS

Glass available in 6, 8, 10 & 12mm, also in 15 & 19mm on request.

PROPERTIES

Unique Qualities: The beauty of textured glass lies in its glacial appearance. Light passes through illuminating the texture and appears to glow from within. People and objects behind the glass are obscured making it a versatile building material for open plan living and working environments!

Glass types:

  • Slumped Glass - Hand textured glass panels (available in Clear, Low Iron and Tinted glass)
  • Float - Clear glass which exhibits a pale green tint which is more apparent when slumped.
  • Tinted float - pale green, pale blue, grey, brown, High performance tints - dark green, dark blue
  • Low Iron - Ultra clear low iron float glass.
  • Mirrored Glass  

TEXTURAL CONSIDERATIONS

The process of slumping texture and patterns into glass sheets involves intense heat to soften the glass, allowing it to melt over and into specially prepared moulds. Kilns, specifically designed for glass forming, provide the necessary heat. The moulds can be made from various refractory materials selected for their specific characteristics.

The resulting slumped glass reflects the artistic input at the design and molding stage and any subsequent treatments. These treatments can include colour applications, obscuring treatments, etching, shape-cutting, edging, adhered embellishments, and metal-ware.

Slumping glass on a mold imparts a textural surface on one side, leaving the other side smooth, glossy, but not flat. Random variations in the background texture are inherent to the process. The edges are fire polished, remaining flat but slightly rounded.

Flat borders can be incorporated where required for specific glazing situations. All standard textures are available as toughened safety glass.

TEXTURED GLASS FEATURE

  • Creates obscurity/privacy with maximum light transmission
  • Safety toughened to meet all safety standards
  • Can be back painted to any colour 
  • Custom designs/ logos can be embossed into the textured glass
  • Used in conjunction with high quality stainless steel fixings
  • Offers easy cleaning and maintenance.

TOLERANCES & EDGEWORK

Due to the expansion and contraction during the processing of glass up to 3mm variation in panel sizes may occur.
Slumped glass can accommodate all standard glass processing treatments such as holes, notches, cut-outs and edge-polishing.

SAFETY CONSIDERATIONS

In glazing situations where Grade A Safety glass is required, most Slumped Glass can be toughened to comply with New Zealand Standards AS/NZS2208 - Safety glazing materials for use in buildings (human impact considerations).
It should be noted that the toughening process may impart some slight "bowing" over the length of the panel, or in some cases, scuff marks caused by the furnace. These are unavoidable.

Chemical Resistance
Glass will resist most acids except hydrofluoric and high temperature phosphoric. Alkalis can attack the glass surface, so it crucial not to get run off from concrete and the like as they will etch the glass surface. The same can happen with some weathering steels and some sealants release chemicals that can stain glass. Hard water with high calcium can be a problem as can geothermal areas for some ceramic glasses.

OUR PROCESS

Our glass process

GLAZING CONSIDERATIONS

All slumped glass products can be installed by local glazing contractors using standard methods and fixing systems in the same manner as flat glass of equivalent thickness. Please refer to New Zealand Standards AS 1288 (glass in buildings - Selection and Installation) for glazing methods & recommendations.

INTERIOR / EXTERIOR?

Generally panels are glazed with the glossy surface to the exterior of the building for ease of cleaning. Where this is not a consideration however, one has a choice based entirely on aesthetics.
