It is a legal requirement to prevent accidents. It is used to warn employees and customers of the presence of glass to help prevent accidents.
a) They are clearly defined with glass manifestation on the glass at two levels; between 850mm and 1000mm and between 1400mm and 1600mm above the floor, contrasting visually with the background seen through the glass (both inside and out) in all lighting conditions.
b) Manifestation takes the form of logo or sign at least 150mm high (repeated if on a glazed screen), or a decorative feature such as broken lines or continuous bands, at least 50mm high.
There are a number of factors to consider when choosing the appropriate manifestation film. The most important thing is it must stand out visually from the surrounding environment. Lighting levels and the colour of the surrounding area have an important impact on the effectiveness of manifestation film.
Lighting levels can vary through out the day and this must be taken into consideration. Generally the darker the environment the lighter the manifestation window film needs to be and vice versa. In situations where direct sunlight falls on the glass causing glare we recommend using a solid manifestation film. In internal spaces where light is softer and more diffused, frosted vinyl’s can be used.
