Building regulations and Health & Safety Legislation calls for glass within certain areas to meet a minimum IMPACT safety performance standard. Where a door or fixed panel is mostly glazed or comprises a single panel of glass, it should be marked permanently to indicate its presence visually.
Those requirements specify that manifestation can take the form of a logo or a sign at least 150mm high repeated if on a glazed screen, or a decorative feature such as broken lines or continuous bands.
The requirements for glass entrance doors are clearly defined with manifestation on the glass at two levels, 850 to 1000mm and 1400 to 1600mm above the floor, contrasting with the background seen through the glass.
Where Glass partitions provide an area with open plan detail they can also create the "gold fish bowl" effect.
Manifestations can be used to provide privacy while still keeping partitions open plan.
Manifestations can also be used as a design feature to compliment other elements within interior design package.
