Tolerances & Quality

Key dimensional, visual and process controls to agree before architectural glass enters production.
Tolerances & Quality
04

Quality control

Agree measurable acceptance criteria.

Dimensional and visual expectations should be tied to the applicable product standard, agreed drawings, viewing conditions and approved samples. Undefined phrases such as “perfect glass” do not create a reliable inspection method.

01

Dimensions & fabrication

Width, height, squareness, thickness, edge finish, hole diameter and position, notches and cut-outs.

02

Flatness & distortion

Overall bow, local bow, roller wave, edge lift, reflected-image quality and heat-treatment effects.

03

Surface & visual quality

Scratches, inclusions, bubbles, chips, coating marks, print coverage and inspection conditions.

04

Colour & optical effects

Coating colour, batch variation, anisotropy, haze, interference and approved project samples.

Typical quality sequence

  1. 01

    Material verification

    Identify glass, coatings, interlayers, spacers and sealants.

  2. 02

    Process inspection

    Check dimensions, edgework, drilling and process parameters.

  3. 03

    Performance coordination

    Arrange required testing, calculations and project documentation.

  4. 04

    Traceable release

    Complete final inspection, identification and packing records.
