Low Iron Glass | Toughened Glass

Glass Cut to Size

What is Low Iron Ultra Clear Glass?

Low-Iron Glass was developed to lessen the green tint (not completely remove) and create a more transparent, clear glass. This is achieved by reducing the amount of iron in the molten glass formula, providing optimal, unobstructed views. In addition to unobstructed views, the edge work on low iron glass is much less green than standard clear glass.

Low-iron glass is ideal for projects where clarity matters most. This is especially important in interior design, where glass shouldn’t impede views or obstruct the brilliance of color in a space. It has a visible light transmittance (VLT) of 91 percent in a standard quarter inch thick glass, while standard clear glass has an 83 percent VLT, making it the clear choice

Where is Low Iron Glass Used?

1.
Select Shape and Input Dimensions

The first step is to cut the glass into your desired shape. Simply use our online calculators to find the shape that fits your space and input the required dimensions below. We can cut glass to all shapes and sizes no matter how irregular. If we cannot fulfil your need online, simply fill out an online enquiry and let us know your requirements.
2.
Select Glass Thickness

Low Iron Ultra Clear Glass is available in thickness ranging from 4 mm to 19 mm. Although our online calculators can cater for sizes up to 900mm x 2800mm, we can process larger panels up to 3210mm X 2250mm. Please send us an enquiry for oversize pane requests.
3.
Extras

Fabrication, such as edging, drilling, cut-outs or etching must be completed before toughening, Please note once the glass has been toughened, it cannot be altered. Therefore please ensure your sizes and glass customisations are correct prior to placing your order.

** Please note our online calculators require measurements in millimetres (mm).

Glass Processing
Maximum Panel Size	Our online calculators can process sizes up to 900mm x 2800mm. This is the maximum size we can ship out via our couriers. For all sizes greater than this please get in touch as special glass couriers will be required to deliver this glass.
Minimum Panel Width	Some restrictions apply to cutting glass as it is very difficult to cut a strip of glass less than the glass thickness. panels thinner than 60mm in any given dimensions will be processed with 3 sides polished and non-toughened glass.
Flat Polish (P.A.R)	All our glass comes with flat polished edges as standard. This is produced by a straight line edging machine and produces a fine polished flat edge suitable for situations where the glass has exposed edges as used in furniture glass and all frameless toughened glass applications.
Bevelled Edges	With straight line and shaped bevelling a beautiful and decorative touch can be added to mirrors, table tops, glass door panels and furniture glass. Available on glass thicknesses 4 - 19mm in a variety of bevel widths and on annealed or toughened glass. The bevel width available is dependent upon glass thickness and the required residual edge.
Tolerances	We manufacture our glass products using different processes, determined by the requirement of the glass product to be made. Because of this, tolerance ranges do vary by the design of the item. We follow all best practices and guidelines outlined by the Glass and Glazing Federation (GGF) and work with the advised nominal tolerance of ± 2mm on all toughened glass products. Laminate glass and decorative glass tolerances may vary.
Dubbed Corners	The sharp corner of the glass it lightly sanded off manually to remove the sharp point. Not as neat as radius corners, dubbed corners are still heavily used just to take off the sharp point and add safety.
Drilling (Holes)
Hole Diameter (Ø)	The hole diameter must be greater than or equal to the thickness of the glass with a minimum of 6mm.
Distance from the Edge	The distance from the edge of the hole to edge of the glass must be greater than or equal to 2 times the glass thickness. For glass 4 to 6mm thick, this hole distance can be reduced to 1.5 times the glass thickness.
Distance from a Corner	In a corner the hole must be greater than or equal to 4 times the glass thickness from the corner and greater than or equal to 2 times the glass thickness from the other edges.
Distance between Holes	The distance between holes must be greater than or equal to 4 times the glass thickness.
Large Hole Diamters (Ø)	Large hole diameters must be less than or equal to 1/3 of the pane width and height.
Minimum Panel Size	In any pane with holes, the minimum width or height of the pane must be 8 times the glass thickness.
Internal Cut-Outs and Notches
Distance between a Cut-Out and Glass Edge	The distance of the cut-out to the glass edge must not be less than 30mm for glass up to 6mm, and 50mm for glass over 6mm.
Distance between a Notch and Glass Edge	The distance between a notch and the glass edge must be greater than or equal to 75mm.
Internal Radius of Cut-Outs and Notches	All rectangular cut-outs must have radius corners with a minimum radius either greater than or equal to the glass thickness. All notches must have holes or radius corners greater than or equal to the glass thickness.
Cut-Out Height or Width	The height or width of a cut-out must not be less than or equal to 1/3 of the pane height or width.
Semi-Circular Cut-Outs	All cut-outs with semi-circular ends must have a 20mm minimum radius and internal corners with a minimum radius greater than or equal to the glass thickness.
'C' Notches	Half hole ‘C’ notches must have a radius greater than or equal to the glass thickness and a slot opening greater than or equal to the glass thickness.
