Glazing Band and Decal Compliance to AS1428.1

Why do we need glazing bands, visual indicators on glazing?

The built environment creates barriers for people with disability, these are usually created without intent. Generally they are the result of designers not having a “working knowledge” of disability and the end users that will be using the environment.

Glazing bands are needed for people with vision impairment to alert them to a barrier created by clear glass, preventing them from walking through it.

The above example illustrates how a minor bit of distortion to an image makes a glazed facade undetectable for someone with a minor vision impairment. Note how the glazing band becomes undetectable.

Below are two examples of clear glazing that is effectively non-detectable even for people without vision impairment. Note, especially the reflection, that will cause confusion in the left-hand image.


When do we need Glazing Bands

Before we consider the use of Glazing Bands, we must first understand where they are required. For this we refer to AS1288:2006.


The following glazed areas are not considered capable of being mistaken for a doorway or opening:

  1. The width is less than or equal to 500 mm.
  2. The height is less than or equal to 1000 mm.
  3. The lowest point of the opening is 500 mm or greater above the floor or ground level.
  4. The glazing is opaque, patterned or a leadlight.
  5. Where a crash/chair rail, handrail or transom is provided and located with its upper edges not less than 700 mm or its bottom edge not more than 1000 mm above the floor level.
  6. The panels are louvres with a blade width (i.e., shortest side) not greater than 230 mm.
  7. The glazing protects a difference in level of 1000 mm or more (i.e. in a balustrade system).

Types of eye conditions

Blindness and low vision can occur as a result of a number of different diseases, conditions or accidents. Some eye conditions are congenital (present at or near birth), others are caused by a disease or infection and others can be caused by accidents or through exposure to UV light (sunlight) or chemicals. Many of the most common eye conditions have no known cause.

Full Vision

Some vision impairment examples are following.

What AS1428.1:2009 says

6.6 Visual indicators on glazing

Where there is no chair rail, handrail or transom, all frameless or fully glazed doors, sidelights, including any glazing capable of being mistaken for a doorway or opening, shall be clearly marked for their full width with a solid and non-transparent contrasting line. The contrasting line shall be not less than 75 mm wide and shall extend across the full width of the glazing panel. The lower edge of the contrasting line shall be located between 900 mm and 1000 mm above the plane of the finished floor level.

Any contrasting line on the glazing shall provide a minimum of 30% luminance contrast when viewed against the floor surface or surfaces within 2 m of the glazing on the opposite side.

Frosted or transparent films MUST NOT be used.


How not to do it!

Examples of glazing band designs

The design of glazing bands does not have to be limited to a 75mm thick band only. Designers can be creative in developing compliant solutions that can also increase client branding.

Option 1


Example of a standard 75mm single colour band.

Option 2

An example of a 125mm thick band that includes the required 75mm band at the botton and another 50mm above that could include a clients branding. Note how the letters sit on the 75mm band (dashed line).

Option 3


Option 4

This shows a more creative example where multiple colours are used as well as logos and end treatment. There really is no limitation to how creative designs can be as long as the 75mm band of one colour is provided.
