9.1 A consistent approach to finishes

9.1.6 Glazing

Glass shall be free of undue defects.

Glass should be checked in daylight, from within the room and from a minimum distance of 2m (3m for toughened, laminated or coated glass). The following are acceptable where they are not obtrusive or bunched:

  • bubbles or blisters
  • hairlines or blobs
  • fine scratches not more than 25mm long
  • minute particles.

The above does not apply to areas within 6mm of the edge of the pane, where minor scratching may occur.
