Glass tolerances

Inspect a dated manufacturer's dimensional example with explicit size and construction assumptions.

Profile and panel

Published process table

Press Glass company standard, Edition 7, March 2020. This educational profile is not the current tolerance commitment of your supplier and does not replace the licensed standard or order agreement.

Shape

Width (mm)

Height (mm)

Proposed construction — outside/reference face first

Named performance reference

A reference replaces the construction. Historical published data is shown only for an unchanged supported build; confirm current supply and product evidence.

Layer 1: glass

Glass ply 1 thickness (mm)

Ply 1 treatment

Ply 1 base material

Ply 1 product (optional)

Ply 1 coating (optional)

Nominal overall thickness: 6mm (includes cavities). 6mm clear toughened

This adds nominal layer thicknesses; it does not establish safety class, structural capacity or manufacturing tolerances. Annealed, heat-strengthened and toughened laminates need the appropriate specified product/system.

Dated dimensional example

Supplier confirmation

Characteristic	Example limit
Length / width deviation	−2 / +2 mm
Width range	1198–1202 mm
Height range	798–802 mm
Maximum diagonal difference	4 mm
Thickness deviation	Request base-pane and film-specific values

Nominal build-up 6.00 mm. Thickness deviation depends on the base panes and interlayer product; request current supplier values. These dated dimensions are not installation clearances. Largest side selects the planning size band. Shaped, special edgework, coatings, bowed or heat-soaked products require their specific agreement.

Manufacturing deviation describes allowable variation from an agreed glass size. It is not the edge clearance to subtract from a frame opening. Thickness, local distortion and installation cover are separate checks.
