AS 1288, 5th, 2021 – Glass in buildings – Selection and installation

This standard ets out procedures for the selection and installation of glass in buildings, subject to wind loading, human impact, and special applications. Glass strength is specified, based on the tensile stresses on the surface of the glass.

AS 1288 does not cover the following:

(a) Glazing in lift cares and lift wells.
(b) Furniture glass, cabinet glass, vanities, glass basins, refrigeration units, internal glass fitments and internal wall mirrors not specifically covered by Section 5.
(c) Buildings and structures with no public access intended for horticultural or agricultural use.

Note 1: The traditional use of these buildings suggests their current construction and glazing practices are acceptable. However considerations should always be given to the brittle nature of glass and the consequences of its breakage.

(d) Windows and doors in heritage buildings as defined by the relevant State or Territorial authority.
(e) Restoration and or repairs to existing headlights.
(f) Special glazing applications which might fail due to the stresses other than tensile stresses, such as shear stresses.
(g) Glass blocks, bricks or pavers.

Note 2: In Australia, legislation requires products to be ‘fit for purpose’. Where glazing is replaced because of breakage or any other reason, it is recommended that the replacement glass conform to the requirements of the relevant sections of this document, unless otherwise permitted by the relevant legislation.
