COMMERCIAL STOREFRONT SECURITY FILM SYSTEMS

Storefront Vulnerability

Why Is Storefront Glass So Easy to Break Through?

Most storefront glass was built for visibility and daylight, not to delay a forced entry.

Large storefront windows and glass entrance doors can be vulnerable points of forced entry, especially when broken glass can be cleared out of the opening.

Security film changes what happens after the glass breaks. The film holds the broken glass together, and an attachment to the frame keeps the filmed glass in the opening longer, so an intruder has to keep working to get through.

It goes on the existing glass, without replacing the framing or the storefront system. We explain what it can and cannot do in What Security Window Film Can and Cannot Do.

Existing storefront glass can often be treated without replacing the glass or framing.

A completed wet glaze attachment connects the filmed glass to the existing frame.

Forced-Entry Delay Systems

Why Does the Attachment Matter?

Film alone holds broken glass together. The attachment is what keeps it in the opening.

Without an attachment, a determined intruder can push the whole sheet of filmed glass out of the frame. When the goal is to delay forced entry, we attach the filmed glass to the frame with a continuous bead of DOWSIL 995 structural silicone on all four sides, in black or white to suit the frame.

Our standard system is 8 mil clear Armorcoat with that four-sided attachment. Higher-risk openings can call for 14 mil film. As an Armorcoat Certified Partner, AAA Glass Tint can sell and install Armorcoat security film thicker than 8 mil.

If a frame cannot support a proper attachment, we explain the limits plainly: film alone still holds broken glass together, but we do not present it as a forced-entry delay system. The film, attachment, glass and frame have to be evaluated together, and results from a tested assembly should not be assumed for every storefront. We explain the options in Security Film Attachment Systems Explained.

Retrofit Advantage

Can You Add Security to Storefront Glass Without Replacing It?

Yes. Security film goes on the glass you already have, and the storefront keeps its appearance.

Replacing storefront glass or framing is a construction project that disrupts retail stores, offices, schools, healthcare facilities and public buildings.

Security film is applied to the inside of the existing glass and attached to the frame. A typical entrance with a pair of doors and sidelights can often be done in one working day, depending on the glass, the framing and the site. The structural silicone keeps curing after we leave: DOWSIL lists curing time at 7 to 14 days and full adhesion at 14 to 21 days, measured at 77 degrees Fahrenheit and 50 percent relative humidity, and temperature and humidity change the rate.

Film Bonds to Glass

The film bonds to the inside surface of the glass and holds the broken pieces together after impact.

Edges Anchor the System

A continuous bead of DOWSIL 995 structural silicone on all four sides connects the filmed glass to the frame.

Frames Must Be Evaluated

Glass type, frame condition, glazing stops and doors versus fixed glass all decide what attachment the opening can support.

Real Commercial Installation

Storefront Security Film for Public-Facing Commercial Glass

Security film systems on existing glass, without changing the building’s exterior appearance.

AAA Glass Tint works with retail storefronts, video gaming locations, schools, municipal and federal buildings, and multi-location operators. We do not subcontract installation; our own crews do the work.

Every project starts with a free assessment of the glass type, the framing, the doors and the level of protection you want, so the system fits the actual building.

Featured Case Study

14 Mil Security Film at a Government Agency

In 2026 our crews installed Armorcoat 14 mil clear security film on 136 panels at a government facility in Northern Illinois, attached to the frame on all four sides.

Every crew member was background checked and badged, and the agency brought us back for additional areas after the first installation. The agency and the building are not named for security reasons.

Does security film stop break-ins?

No film makes glass impossible to break through. Security film holds broken glass together, and with an attachment to the frame it delays entry by making an opening take longer to create. If someone has enough time and tools, they can still get in. We explain how this works against a smash-and-grab in Smash-and-Grab Protection for Storefronts and Video Gaming Locations.

Is the attachment necessary?

When the goal is to delay forced entry, yes. Without it, the whole sheet of filmed glass can be pushed out of the frame. Film alone still holds broken glass together, but we do not present it as a forced-entry delay system.

What system do you install?

Most often 8 mil clear Armorcoat with a four-sided DOWSIL 995 wet glaze attachment. Higher-risk openings can call for 14 mil film. We size the system to the glass, the opening and the level of protection you need.

Can it be installed on existing glass?

In many cases, yes, after we check the glass and the frame. Doors take more attention than fixed sidelights, because hardware, stops and clearances all affect the attachment.

Will it change the appearance?

Clear security film keeps daylight and the view through the glass. The structural silicone attachment is visible at the edges, so we talk through black or white sealant before installation.

What happens if the glass breaks later?

The film and the attachment come out with the broken glass. Replacing the glass means installing new film and a new attachment on the replacement glass, so plan for it in any glass repair.
