Manufacturer Partners

Authorized Installer of Leading Security Film and Glazing Brands

We partner with manufacturers whose products are built and tested to resist impact and intrusion.

SafetyShield by Madico is a line of heavy-duty security films designed to hold glass together after impact. Combined with a frame attachment system, it helps openings withstand repeated strikes.

Riot Glass manufactures security glazing systems used in schools, government buildings, and other high-risk facilities. Its products come in multiple protection levels to match the threat each entrance faces.

3M Safety and Security Window Films use a multilayer construction that absorbs impact energy and resists tearing. Paired with a 3M anchoring system, the film strengthens the bond between glass and frame.

Our Solutions

Security Window Film and Glazing Solutions for Every Opening

No two buildings share the same vulnerabilities. We recommend only the protection your openings actually need.

Security Window Film

A clear protective layer reinforces existing windows and doors, making the glass much harder to breach.

Security Glass

Retrofit panels fit into existing frames, so you can upgrade weak glass without replacing the whole window.

Security Screens

Steel mesh looks like an ordinary insect screen but resists cutting, prying, and kicking.

Security Shades

Nightlock lockdown shades deploy quickly to block sightlines into a room.

Security Shutters

Nightlock shutters add a solid barrier over exterior openings, entry points, and interior door glass.

The Science

Multiple Security Solutions, One Coordinated Plan

Every facility has different entry points, glass types, and security priorities. Strong Glass assesses your property and recommends a combination of solutions suited to those risks, which may include security window film, reinforced glass, and protective shutters. The result is a custom plan that addresses vulnerable openings while accounting for how your facility operates.

  • Identifies vulnerable doors, windows, and other openings
  • Matches each location with an appropriate security solution
  • Combines solutions where additional protection is needed
  • Accounts for visibility, access, and day-to-day use

Industries

Security Film Solutions by Industry

Each facility type follows its own schedule and compliance rules. We tailor every safety and security window film project to the way your building runs.

Schools

Main entries and classroom windows are the first line of defense during a lockdown. Projects are scheduled around the academic calendar to avoid class time.

Healthcare

Hospitals and clinics need protection for emergency departments, pharmacies, and lobbies without closing patient areas. Our crews follow infection control and patient privacy rules on every job.

Houses of Worship

Churches, Mosques & Synagogues: Places of worship keep their doors open to the public, which often leaves glass entrances exposed. As an FBSM member, we help congregations add discreet protection that respects their sanctuary’s character.

Government

Courthouses, city offices, and public buildings must remain open to visitors while staying secure. Our detailed project scopes help support grant applications, purchasing reviews, and security audits.

FAQ

Frequently Asked Questions

How can 3M safety and security window film protect a building?

3M safety and security window film helps existing glass stay intact when it is struck. The film is a tough, optically clear polyester laminate applied to the inside surface of the glass. It resists tearing, delays unauthorized entry, and lowers the risk of injury from flying shards.

No, clear safety and security window film is nearly invisible after installation. Your windows keep their open feel, and natural light continues to fill each room. Tinted options are also available if you want added glare or heat control.

Installation time for safety and security window film depends on the number of openings, the glass sizes, and the anchoring method selected. A single entrance can often be finished in one day, while a full campus is usually completed in phases. Your specialist will provide a project timeline along with the proposal.

Yes, every installation is covered by the product manufacturer’s warranty. Following each manufacturer’s installation standards keeps that coverage valid. Terms vary by product, and we will explain them before work begins.

No, security film is not bulletproof. Its purpose is to keep glass in place during a physical attack, not to stop bullets. For openings that need ballistic protection, we can recommend higher-rated glazing from Riot Glass.
