Window Film Attachment Systems for Homes and Offices.

An attachment system anchors security film to the window frame, so the whole pane stays in the opening after the glass breaks. It's what turns film from glass safety into real break-in and earthquake protection. Installed by certified 3M installers across Orange County and Los Angeles.

Security film attachment systems

Film holds the glass. The attachment holds the pane.

Security film keeps broken glass from falling apart, but a broken pane can still be pushed out of the frame in one piece. An attachment system bonds the edge of the filmed glass to the frame on 2 or 4 sides, so the opening stays closed after repeated hits, a quake or a storm. It's the step many installers skip, and 3M requires it for break-in applications of its security films. An attachment needs a frame with enough depth to bond to, so we measure every frame during your consultation to confirm it's possible.

One home. One office. Glass that stays in the frame.

Both installed by Comfort Pro. The film is clear. The attachment is a clean, even bead along the frame edge.

Wet glaze color-matched to a white frame

A home window facing the back patio. Security film is bonded to the frame with a white bead that matches the frame, so the attachment blends in and the glass stays in the opening even after it breaks.

Does every window need an attachment? No. For earthquake and accident safety on lower-risk windows, film alone is often enough. See our shatter-resistant window film page. For storefronts, entry doors, ground-floor windows and higher-risk glass, we usually recommend adding an attachment system, as long as the frame has the depth for one.
What to watch for

What a bad attachment looks like.

Real attachment jobs we've seen in the field. Compare them to the clean beads above.

Bad window film attachment: lumpy, dented silicone bead along a black window frame
Avoid

Lumpy, unfinished bead

No tape lines and no clean tooling, so the bead is dented and uneven along the whole frame.

Bad window film attachment: silicone bead peeling away from the frame at the corner
Avoid

Silicone peeling off the frame

The bead has pulled away from the frame. Once it lets go, it can't hold the glass in the opening.

Bad window film attachment: excess silicone piled into the corner of a window frame
Avoid

Silicone piled into the corner

Too much silicone globbed into the corner, with no straight line along the glass or the frame.

What good looks like: a straight, even bead with crisp edges on the glass and the frame, in black or a color that matches your frames. Before you hire anyone, ask to see close-up photos of their attachment work.
Attachment options

Choose the method and the coverage.

Every attachment needs a frame with proper depth. We measure your frames first, then recommend the attachment that fits your glass, your risk and the look you want.

3M Impact Protection Attachment

3M's own wet glaze sealant, engineered to anchor 3M security film to the frame. It's the attachment 3M recommends whenever 3M film is installed, and a 4-sided install adds 2 years to 3M's 10- and 12-year commercial film warranties.

Best for: 3M security film 3M Impact Protection Attachment (IPA)

Structural silicone wet glaze

A bead of commercial structural silicone bonds the filmed glass to the frame. Works on most frames and comes in black or a color that matches your frames.

Best for: most frames and film brands Dow 995 or GE SCS2000 structural silicone

Mechanical attachment

An aluminum bar fastened with screws and tape clamps the filmed glass to the frame. Madico rates it its strongest attachment, tested to hold 500 to 800 pounds per linear foot. The frame has to accept screws.

Best for: the highest-risk glass Madico FrameGard with SafetyShield film

4-sided or 2-sided coverage

4-sided attachment anchors every edge of the pane for the most forced-entry delay. 2-sided attachment anchors two edges when the frame or the budget doesn't allow all four.

Best for: matching protection to each opening
Which films pair with an attachment? 3M Ultra S800, 3M S2400, 3M Ultra Night Vision 25 and 3M Safety S70 Exterior, plus security films from Madico, SafetyShield and ArmorCoat. We're a 3M Premier Elite Dealer, so we can register the 3M warranty for you.

Attachment system questions.

What is a window film attachment system?

It's a way to anchor security film to the window frame. Film alone holds broken glass together. The attachment keeps the whole pane in the frame so it can't simply be pushed in.

Do I need an attachment system with security film?

For storefronts, entry doors and higher-risk glass, we usually recommend it. 3M requires its attachment for break-in applications of its security films. For earthquake and accident safety on lower-risk windows, film alone is often enough.

Can you see the attachment?

A little. Wet glaze is a neat bead along the frame edge, in black or a color matched to your frames. Mechanical attachment is a slim aluminum bar along the frame. The film itself stays clear.

Can every window get an attachment system?

No. An attachment needs a frame with enough depth for the bead or bar to bond to. Some frames, like thin or flush glazing beads, don't have room. We measure every frame during your consultation and tell you which openings can take an attachment.

Does an attachment system help in an earthquake?

Yes. When glass breaks in a quake, the film holds the pieces together and the attachment keeps the pane in the frame instead of letting it fall out.

Does an attachment system affect the warranty?

It can extend it. 3M adds 2 years to its 10- and 12-year commercial film warranties when a 4-sided 3M attachment system is installed. For example, Ultra S800 goes from 12 years to 14.

How long does the attachment take to cure?

Wet glaze needs time to cure. Don't clean the attachment for at least 36 hours, and full cure can take days to weeks depending on weather. Mechanical attachment doesn't need to cure.

Which attachment systems and films do you install?

We install 3M Impact Protection Attachment, Dow 995 and GE SCS2000 structural silicone, and Madico FrameGard. We're a 3M Premier Elite Dealer and install 3M Ultra S800, S2400, Ultra Night Vision 25 and Safety S70 Exterior, plus security films from Madico, SafetyShield and ArmorCoat.
