PANEL SIZES

Maximum single panel sizes: 3000 x 1500mm

GLASS THICKNESS

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

PROPERTIES
Glass types:

  • Slumped Glass - Hand textured glass panels (available in Clear, Low Iron and Tinted glass)
  • Float - Normal locally produced 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, imported.

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 moulds. The heat is provided by kilns, specifically designed to suit the glass forming process. The moulds can be a variety of materials (refractories) selected for their particular characteristics.
The resultant slumped glass reflects the artistic input at the design and moulding 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 mould 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 GradeA 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.


OUR 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.
