Northern Illinois' Commercial Window Film Specialists Since 1984

No film makes glass impossible to break through, but the right system delays forced entry. Security film holds broken glass together. When the goal is to delay an intruder, the film is attached to the frame, typically with a wet glaze structural silicone, so the glass and film stay in the opening longer under attack. Security film systems are used on school entrances, government facilities and retail storefronts. We explain the difference in What Security Window Film Can and Cannot Do.

Chicago buildings deal with summer solar heat gain and winter heat loss through the glass. Depending on the film and existing glass, solar control film can substantially reduce solar heat gain. For example, Solar Gard Sentinel Plus Silver 20 OSW lists up to 82 percent solar energy rejected on 1/4 inch clear glass. Low-E window film can also improve heat retention during colder weather. The result can be more even interior temperatures and fewer hot spots near the glass. We compare film with replacement windows in Low-E Window Film vs. Window Replacement.

Video gaming operators often want stronger glass protection for their equipment and patrons. AAA Glass Tint has installed security film at more than 30 Illinois video gaming locations, typically 8 mil or 14 mil Armorcoat attached to the frame with a four sided DOWSIL 995 wet glaze when the goal is to delay forced entry. We size the system to the glass, the opening and the level of protection required.

Window film can greatly reduce fading, but no film stops it completely. Solar Gard's clear and solar control films block more than 99 percent of ultraviolet light, a major contributor to fading. Decorative and frosted films vary, so we check the figure for the film you choose. Visible light and heat also contribute, so darker or more heat-rejecting films reduce fading further. We can show you the fade reduction figure for the specific film and glass we recommend.

Not yet. Chicago is considering a bird-friendly building ordinance, O2026-0024083, that would require bird-friendly glazing within 100 feet of grade on new construction and on many renovations, for permits applied for from January 1, 2027. As of October 9, 2026, it is in committee and has not been adopted. Illinois law already requires bird-safe design, but only on state buildings. The proposed ordinance names exterior-applied films that meet American Bird Conservancy criteria as one qualifying method. We cover the details in Chicago's Proposed Bird-Friendly Building Ordinance, and our bird strike film page covers the products we install.

Proper film selection greatly reduces the risk of thermal stress breakage, but no installer can guarantee that glass will never break. Manufacturers publish film-to-glass guidance showing which films are approved for different glass types and when written approval is required. The film manufacturer's warranty may include glass breakage or seal failure coverage when its requirements are met. The original window manufacturer's warranty is separate, and aftermarket film may affect that warranty depending on the manufacturer's terms. We explain how compatibility and warranty coverage are checked in Will Window Film Crack Your Glass?

As of October 2026, commercial window film projects can range from the low thousands of dollars to several hundred thousand dollars. The ranges overlap because price depends on much more than square footage, including the film and system, security attachment, access equipment, removal of existing film, prevailing wage and other labor or scheduling requirements. We explain what moves the price in What Commercial Window Film Costs, and What Drives the Price. For a number for your building, request a free assessment.

For most conference rooms and glass partitions, frosted or gradient privacy film is the simplest choice: it blocks the view while keeping natural light. Reflective films give daytime privacy, though they depend on lighting and can reverse at night. For branding, decorative film adds logos, patterns and etched-glass looks to existing glass and can be removed or changed later. Where the goal is to hide screens rather than the whole room, Casper cloaking film keeps the glass visually open. We show samples on your glass before you choose.

Look at what each contractor is actually proposing, not just the price. A good bid names the exact film, confirms it is approved for your glass, says who will install it, explains the warranty and, for security film, how the film is attached to the frame. Film-to-glass compatibility matters because the wrong film on the wrong glass can risk thermal stress breakage; we explain that in Will Window Film Crack Your Glass? AAA Glass Tint installs with our own crews, registers the manufacturer's warranty for the film installed, and is an Armorcoat Certified Partner for security film.
