Glass Manifestations

Manifestation Large areas of transparent glazing used to subdivide a building may not be immediately apparent, particularly under certain lighting conditions. People in passage in or about the building may not be aware of the glazing and may collide with it. The glazed areas referred to include large uninterrupted areas of transparent glazing which form, or are part of, the internal or external walls and doors of shops, showrooms, offices, factories, public and other non-domestic buildings.Permanent manifestation is only necessary when other means of indicating the presence of the glazing are not present.

When manifestation is required it should be of a sufficient size to be immediately obvious and should be positioned between 600 and 1500mm above floor level and preferably be permanent and durable.
