Are distraction markers required on glass doors and walls?

In many areas, yes. Building codes often require visible markings on floor-to-ceiling glass, glass doors, and large glass panels. These markings, called distraction markers or manifestation markers, help prevent people from walking into glass they don’t recognize as a barrier. Where they are required, the markers typically need to meet minimum size and placement requirements, such as being positioned at eye level and large enough to be easily noticed.

Decorative Window Films as Distraction Markers

Decorative window films are a practical way to add distraction markers. The 3M FASARA Glass Finishes line includes stripe and dot patterns that work well for this purpose. Stripe patterns such as Seattle and Fusion Pearl use lines of varying thickness and density, while dot patterns such as Shizuku, Kanon, and Luna (6 and 9) create a textured look that resembles etched glass. These patterns can meet marking requirements and add privacy to offices and conference rooms in a single installation. Whether a specific pattern meets your local requirements depends on its density, size, and placement, so an installer can help you choose the right option. Because the film is applied directly to your existing glass, the placement and coverage can be adjusted to fit your space and updated later without replacing the glass.

Keep in mind that glass markings are separate from safety glazing requirements, which are rules about what type of glass (such as tempered or laminated glass) can be used in certain locations. Adding decorative film to glass does not change whether that glass meets those requirements.

How to Find Distraction Marker Requirements in Your Area

Requirements depend on your state, city, and building type, so it’s worth confirming before you choose a design. Here are a few ways to find out what applies to your project:

• Contact your local building department. Your city or county building department enforces building codes in your area and can tell you whether distraction markers are required for your space and what size and placement rules apply.
• Check which codes your state has adopted. Most states base their building codes on the International Building Code, but each state and city adopts its own version, sometimes with changes. The International Code Council’s code adoption map shows which codes are in effect where you are. The International Code Council also offers free online access to read the model codes.
• Ask your property manager or landlord. If you lease your space, your building may have its own standards for glass markings and approved materials.
• Talk to a professional window film installer. Experienced installers work with distraction markers regularly and are familiar with what is commonly required in their area. They can help you understand your options, coordinate with your building department if needed, and recommend a film and layout that meets requirements while fitting the look of your space.
