Glazing Manifestation Regulations & Heights
Large areas of transparent glazing can sometimes be difficult to see, creating a risk of people walking into glass doors, screens or partitions.
Glazing manifestation is used to make the presence of the glass clearly apparent.
In England, guidance relating to the visibility of glazing is contained within Building Regulations 2010 – Approved Document K: Protection from falling, collision and impact.
What Height Should Glazing Manifestation Be?
Approved Document K provides guidance for manifestation on glass doors and glazed screens.
Manifestation should be clearly visible within two height zones above finished floor level:
Lower manifestation zone: 850mm to 1000mm
Upper manifestation zone: 1400mm to 1600mm
These two zones help ensure that large areas of transparent glazing are clearly apparent to building users.

What Can Be Used for Glazing Manifestation?
Glazing manifestation does not have to consist of dots.
Approved Document K explains that manifestation can take various forms, including broken or solid lines, patterns and company logos.
This allows manifestation to become part of the overall design of an interior while still making the glazing clearly apparent.
Common types of glazing manifestation include:
-
Frosted dots and squares
-
Solid or broken bands
-
Decorative patterns
-
Contrasting vinyl designs
-
Company logos
-
Bespoke graphics and branding
Broken lines or continuous bands used as decorative features should be a minimum of 50mm high.
Where Is Glazing Manifestation Used?
Glazing manifestation is commonly used where large areas of transparent glazing might otherwise go unnoticed.
Typical applications include full-height glass doors, glazed office partitions, entrance screens, reception areas, commercial buildings, shops, schools and other public buildings.
Approved Document K also provides examples of door-height glazing that may already be sufficiently apparent because of features such as substantial framing, rails, large handles or push plates.
Does Glazing Manifestation Have to Be 50mm High?
The 50mm measurement is particularly relevant to decorative features such as broken lines or continuous bands.
Approved Document K also provides guidance for other forms of manifestation. For example, a logo or sign may be used where it provides a sufficiently prominent visual indication of the glazing.
The most appropriate solution will therefore depend on the type and design of the manifestation being used.
Can Company Logos Be Used as Glazing Manifestation?
Yes. Company logos and other bespoke designs can be incorporated into glazing manifestation.
This can be particularly effective in offices, reception areas and commercial buildings, where manifestation can make glazing more apparent while also reinforcing a company's branding.
