SLUMPED GLASS PRODUCT INFORMATION

Textured Slumped Glass. Combining Organic and Directional elements. Slumped textured glass can be produced in large panel sizes, for divider walls or partitions, creating a beautiful decorative finish to your corporate space, while creating privacy.

In addition, colour finishes can also be applied. Slumped glass panels can be used as Cladding or Facades, pressed against other wall surfaces; ideal for front entrance Hotel or Corporate Lobbies.

Slumped textured glass is available in a range of different glass thicknesses 6, 6, 10, 12 and 19mm, clear or low iron glass, and safety toughened (tempered) or annealed. Panels can be produced up to 18000mm x 3000mm in clear or low iron glass. Or choose from our rich tinted glass or vibrant coloured glass options.

The maintenance free, non-porous surface of our slumped glass allows the glass to appear bright, new, and clean, for many years to come.

TEXTURAL CONSIDERATIONS

The process of slumping texture and patterns into sheets of glass involves intense heat to soften the glass sufficiently for it to melt over and into specially prepared molds. The heat is provided by kilns, specifically designed to suit the glass forming process. The molds can be a variety of materials (refractories) selected for their particular characteristics.
The resultant slumped glass reflects the artistic input at the design and molding stage, and the subsequent treatments that might be used. These include colour applications, obscuring treatments, etching, shape-cutting and edging, adhered embellishments and metal-ware.
The process of slumping glass on a mold imparts a textural surface on one side leaving the other smooth, glossy but not flat. Random variations in the background texture are immanent in the process. The edges are fire polished and remain flat but slightly rounded. 
Where required for specific glazing situations flat borders can be incorporated. All standard textures are available as toughened safety glass.

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.
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.
