Manifestation & Glass Safety Stickers

Our safety glass manifestations are available as a pack of individual stickers, in ready-made strips, or as a film which can be ordered by the meter or cut to size. They are designed to highlight glazed areas to comply with building regulations, to help avoid the risk of collision. They are therefore ideal for office partitions, public areas and patio doors. They are very easy to apply using soapy water, and the application tool provided. Please read more to find out about legal requirements with regards to large glazed areas in public buildings.

Window Safety Stickers

What are manifestations?

Manifestations are self-adhesive devices designed to highlight glazed areas. They can consist of rows of stickers - e.g. manifestation dots - or a continual strip of window film of contrasting colour with the glass - e.g. glass safety strips or frosted glass strips.

Document K of UK Building Regulations

Manifestations are designed to mitigate the risk of collision at work, in retail outlets or in public spaces, where it is a legal requirement to highlight large glazed areas is stipulated in Document K: Building regulation in England covering the buildings users protection from falling, collision and impact in and around the building.

Critical locations


Critical locations 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 or other non-domestic buildings.


The risk of collision is greatest when two parts of the building, or the building and its immediate surroundings, are at the same level but separated by transparent glazing and people may think they can walk from one part to the other.

Permanent methods to indicate glazing, and alternative methods


People moving in or around a building might not see glazing in critical locations and can collide with it. To avoid this one of the following should be adopted.

a. Use permanent manifestation to make glazing apparent (see paragraph 7.4).

b. Use alternative indications of glazing, such as mullions, transoms, door framing or large pull or push handles.


Provide glass doors and glazed screens (including glazed screens alongside a corridor) with all of the following.

a. Manifestation at two levels, between 850mm and 1000mm, and 1400mm and 1600mm off the finished floor level.

b. Manifestation that will contrast visually with the background seen through the glass, both from inside and outside, in all lighting conditions.

c. Manifestation in the form of a logo or sign, a minimum of 150mm high (repeated if on a glazed screen), or a decorative feature such as broken lines or continuous bands, a minimum of 50mm high.

d. Where glazed doors are beside or part of a glazed screen, they are clearly marked with a high-contrast strip at the top and on both sides.
