What is a Security Window Film Attachment System?

A security film attachment system is a method used to bond security window film to the window frame, therefore helping to prevent the entire pane of glass from being blown or pushed out of the frame. 3M Company’s attachment system is called Impact Protection Adhesive (IPA).

How Does 3M’s Attachment System Work?

IPA is a structural silicone adhesive used to bond the security film, glass, and window frame together. During installation, the window’s gaskets may need to be trimmed, followed by installing the film as close as possible to the window frame. A bead of IPA structural silicone adhesive is then applied directly against the frame, overlapping the security film and often taking the place of the original gaskets.

Benefits of an Attachment System

Using an attachment system alongside security window film is crucial for enhancing the overall effectiveness of the security measures for windows. Here’s why the combination is important:

1. Improved Intrusion Resistance: Security window films are designed to make glass shatter in place by holding the pieces together when the glass is broken. However, the glass and film can still be pushed out of the window frame as a single piece during a forceful impact. An attachment system helps to ensure that the film is anchored to the window frame, significantly hindering the glass from being dislodged and deterring intruders.
2. Enhanced Safety During Natural Disasters: In the event of natural disasters like earthquakes or severe storms, windows can be a major vulnerability. An attachment system can provide additional protection against impacts from flying debris, reducing the risk of injury from broken glass and maintaining the integrity of the building envelope.
3. Mitigation of Blast Hazards: In areas where there is a risk of explosions (accidental or intentional), glass fragments can be one of the most lethal projectiles. Security window films with an attachment system can mitigate the hazards associated with flying glass by anchoring the shattered glass to the window frame.
4. Compliance with Safety Regulations: Certain building codes (i.e. the use of tempered glass) and safety regulations may require the use of attachment systems with security films to ensure a higher standard of occupant safety and security.
5. Energy Efficiency and UV Protection: While the primary function of the attachment system is security, it complements the security window film’s ability to provide additional benefits such as energy efficiency (by reducing solar heat gain) and protection against UV rays.

In conclusion, while security window films significantly enhance window safety and security, the addition of an attachment system amplifies these benefits, helping to provide a comprehensive solution for protecting property and occupants.
