What Does Door Manifestations Mean In Construction?
Door manifestations in construction refer to the application of a frosted film or other decorative treatment to large expanses of clear glass, such as windows and doors, in order to make them visible and prevent injury through collisions.
This is done in accordance with building regulations, which require that transparent glazing with which people are likely to come into contact while moving around in or about the building must incorporate features which make it apparent.
Manifestation typically takes the form of a logo or sign at least 150mm high (repeated if on a glazed screen), or a decorative feature such as broken lines or continuous bands.
In addition, doors should be apparent from the side if they can be held open, and where glazed doors are beside a glazed screen, they should be marked with a high contrast strip along the top and at the sides.
Glazing installations that require manifestations include certain glass installations that pose a significant risk to the public.
Manifestations need to be placed between a height of 850mm and 1000mm on a glass pane, and again between 1400mm and 1600mm.
Do Glass Manifestations need to feature a specific design? No, there is no requirement for manifestations to feature any specific design.
What Is The Design Of Door Manifestations?
Manifestation is a treatment applied to glass windows, doors, partitions, and other large expanses of clear glass in order to make the glass visible and prevent injury through accidental contact.
Manifestation typically consists of a frosted film applied at specified locations on clear glass. Regulations do not dictate the appearance of the manifestation, but standard designs include dots, squares, and simple patterns.
Alternative solutions such as mullions, transoms, door frames or large pull handles/push plates may also be acceptable.
The National Construction Code (NCC) requires that transparent glazing with which people are likely to come into contact while moving around in or about the building should incorporate features which make it apparent.
This includes two rows of 50-75 mm white or frosted dots, as well as high contrast strips for glazed doors beside a glazed screen. Standard industry practice is to have etched markings on door leaves to ensure compliance.
Glass manifestation is also required by law for doors with single glass panes and considerable frames, as well as unframed or narrowly framed glass doors with sizable handles or push plates on each pane of glass.
Manifestation can improve safety and security in a building by making the glass more visible and therefore less likely to be accidentally walked into or through.
What Are The Materials Used In Door Manifestation?
Manifestation is a treatment applied to glass windows, doors, partitions and other large expanses of clear glass in order to make the glass visible and prevent injury.
According to Building Regulations 2000: Part M, manifestations must take the form of a 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.
Manifestations are also required for all elements of glass in ‘Critical Locations’ as determined by Diagram 5.1 in Approved Document K.
Alternative solutions such as mullions, transoms, door frames or large pull handles / push plates may also be acceptable.
In addition, doors should be apparent from the side if they can be held open and where glazed.
Making manifestations on glass work with your design can include using a substantial frame around the glazing or glass door with bespoke handle designs of architectural metals to satisfy the requirement for manifestation.
There has also been an increase in the popularity of steel or steel look doors for commercial developments which offer projects a touch of ageless class and design.
How Do You Apply Manifestation To Glass?
Applying manifestation to glass involves making temporary marks on the glass with a tape measure and pen, laying the manifestation on a clean surface, slowly removing the backing sheet, spraying the surface of the manifestation with soapy water solution, and then applying it to the window using the marks as a guide.
The soapy water solution will help slide it into position. Once in place, spray the manifestation with water and use a squeegee to push out any water or bubbles to the edge of the pane.
Glass manifestations are designed to make large expanses of clear glass visible and prevent injury through contact with them.
Manifestations are typically created from frosted film applied at specified locations on clear glass.
Building Regulations 2000: Part M states that transparent glazing with which people are likely to come into contact while moving around in or about the building must incorporate features which make it apparent.
Manifestations are usually made from frosted vinyl dots or squares applied onto glazing to obscure vision and help prevent people from walking into the glass.
They can also be made by adding decoration to the surface or infusing colour into the glass.
Manifestations need to be placed between 850-1000mm and 1400-1600mm above floor level, contrasting visually with background seen through glass.
The design of manifestations is not dictated by regulations but they must be clearly defined on glass.
