Glass Highlighting - Diamonds - Safety Signs by Caledonia Signs

Glass highlighting diamonds—also known as safety decals, manifestation stickers, or visibility markers—are essential for enhancing the visibility of large glass panels and preventing accidental collisions. They are commonly used in public and commercial spaces where frameless or clear glass is part of the design.

These diamonds are primarily installed to prevent people from walking into transparent glass surfaces, which can cause serious injuries. In modern buildings that feature large glass walls, partitions, or doors, the glass can be almost invisible, especially in bright lighting or when cleaned well. Highlighting diamonds act as a visual cue, alerting people that a solid surface is present without obstructing light or aesthetic transparency.

The most common places to install glass highlighting diamonds include office buildings, schools, shopping centres, hospitals, airports, and modern homes—anywhere large panes of frameless or minimal-frame glass are used. Regulations in many countries, such as the UK’s Building Regulations Part K, specifically require visible markings on glass surfaces at certain heights.

These glass highlighting diamonds are made from frosted vinyl and are applied at eye level to catch attention from both adults and children. Aside from safety, they can also enhance design, we can provide glass highlighting in different patterns, colours, or custom branding, which can provide both a visual warning and a decorative element. This makes them a practical and aesthetic solution for improving safety in glass-heavy architectural spaces.

Frosted Self-Adhesive Vinyl: Self-adhesive vinyl is easy to apply and it’s budget-friendly. Its adhesive backing allows for easy application to a variety of surfaces, however it is commonly used on glass surfaces. It is made from a translucent film with an adhesive backing, allowing it to be easily applied to windows, doors, and partitions without the need for permanent etching or sandblasting to create a frosted, etched-glass effect. One of its key benefits is privacy without sacrificing natural light. It is often used in businesses to divide workspaces while maintaining an open, light-filled environment.
