Modern glass facades are a dominant feature of urban architecture in cities throughout the world. However, not only new buildings are equipped with this design element; also many older buildings are visually upgraded by the addition of a glass facade fitted to the existing facade. In many such cases, toughened glass is used as the structural material.

In recent years, there has been a growing number of cases of glass breakage on toughened glass facades caused by nickel sulphide inclusions in the glass. As a result, glass weighing up to 300 kg was able to fall unresisted from a great height, severely endangering the lives of passersby. Also edge damage, constrictions to the glass or external mechanical influences can lead to glass breakage. In the event of spontaneous glass breakage, Profilon FF holds the facade glazing in place and prevents it from falling.

The safety film holds the pane of toughened glass in the frame construction and therefore increases the residual carrying capacity. Depending on the type of facade structure, practical tests on facades equipped with Profilon FF revealed a residual carrying capacity of more than 150 days in the case of glass breakage. This vastly exceeds the residual carrying capacity of 3-5 days specified by the building authorities. A special adhesive holds the glass splinters in place, while the structure of the film provides the necessary elasticity in order to ensure the bond between glass and film even under wind loads.

Profilon FF:
retains glass splinters

• explosion resistance
• splinter retention
• delays the spread of fire (no smoke)
• is UV-absorbent

Profilon FF can be retrofitted to all types of toughened glass, including those with enamelled surface. Because of the wide variety of facade construction types, there is no general building regulation. As a rule, an application for approval must be filed for each individual case, and is usually allowed after corresponding review.
