What Is Breakaway Glass?

Breakaway glass is a specially engineered material designed to fracture safely and predictably on impact, replicating the appearance of real glass shattering without the associated risk of serious injury. It is the industry-standard solution for any film, television, or theatrical production that requires an actor to break a window, smash a bottle, crash through a display case, or interact with any glass-like prop that must shatter on camera.

Breakaway glass is not real glass. It is manufactured from sugar-resin compounds, synthetic resins, or specialized rubber formulations that are engineered to fragment into blunt, non-lacerating pieces upon impact. The key properties that distinguish breakaway glass from real glass are:

• Controlled fracture pattern: Breakaway materials shatter consistently and predictably, allowing special effects coordinators to plan and rehearse stunts with confidence.
• Reduced injury risk: Fragments are designed without the razor-sharp edges characteristic of real glass. While minor scratches are possible, the risk of cuts, lacerations, and embedded shards is dramatically lower.
• Camera-ready appearance: High-quality breakaway glass is optically similar to real glass on camera, reflecting and transmitting light in ways that are convincing at standard shooting distances.
• Consistent repeatability: Productions can purchase multiple identical pieces for successive takes, ensuring visual continuity across coverage.

Common applications include window breaks for action sequences, bottle hits in fight choreography, table crashes, vehicle windshield effects, display case destruction, and any scene where a performer must come into contact with shattering material.

Types of Breakaway Materials

Not all breakaway materials are the same. The film and television industry uses several distinct types, each with specific advantages depending on the requirements of the scene.

Sugar Glass (Traditional)

Sugar glass is the oldest and most traditional form of breakaway material, made primarily from heated sugar that is cast into molds and allowed to harden. It produces a convincing, glass-like transparency and shatters satisfyingly on camera. Sugar glass dissolves in water, which simplifies cleanup but also makes it unsuitable for outdoor shoots in wet or highly humid conditions. It is relatively fragile and must be handled carefully before the take.

Resin-Based Breakaway Glass

Modern resin-based breakaway glass has largely supplanted sugar glass in professional productions. Manufactured from synthetic resin compounds, these panels and objects offer greater durability during handling, more consistent break patterns from piece to piece, and better resistance to ambient humidity. Resin breakaway glass is available in a wide range of flat sheets and pre-formed shapes. It is the most commonly used breakaway material in contemporary film and television production.

Breakaway Rubber Glass

Breakaway rubber glass is a flexible, soft material designed for stunts where a performer makes direct, close-range contact with the breaking object. Unlike rigid resin breakaway glass, rubber glass bends and deforms on impact rather than shattering into fragments, making it the safest option for scenes where an actor is thrown through a window, struck with a bottle, or otherwise comes into forceful contact with the prop. It is commonly used for close-contact fight choreography and any gag where the performer cannot be adequately shielded.

Breakaway Foam and Structural Materials

For larger set pieces that need to collapse or break apart—walls, doors, bricks, cinder blocks—productions use breakaway foam and structural materials. These are rigid enough to look convincing as masonry or heavy construction materials but are lightweight and fracture safely when struck. Foam bricks and breakaway cinder blocks are standard items for action sequences involving wall breaches, building collapses, and demolition scenes.

What Products Are Available

A comprehensive breakaway glass inventory covers the full range of objects that productions commonly need to destroy on camera. The following categories represent the core product types used across the film and television industry, all of which are stocked by SPFX Supply.

Breakaway Glass Sheets

Breakaway glass sheets are flat panels used for windows, picture frames, display cases, mirrors, and any flat glass surface that needs to shatter. They are available in multiple standard sizes and can be cut or scored for specific break patterns. Sheets start at approximately $70 CAD and are the most versatile breakaway product for set construction.

Breakaway Glass Shards

For scenes that require pre-scattered glass debris—crime scene setups, aftermath shots, or layered destruction effects—breakaway glass shards provide camera-ready fragments without the need to break a full panel. Available from approximately $150 CAD, they save time on set and ensure consistent scatter patterns across takes.

Breakaway Bottles

Breakaway alcohol bottles are among the most frequently used props in film production. Available as wine bottles, champagne bottles, and beer bottles, they are designed to shatter convincingly when struck against a surface or over a performer. Breakaway bottles start at approximately $30 CAD each and are typically single-use items, so productions should order enough for multiple takes and rehearsals.

Breakaway Cups, Mugs, and Glassware

Breakaway cups and mugs—including wine glasses, champagne flutes, beer mugs, and coffee cups—are essential for bar scenes, dinner table sequences, and domestic conflict choreography. Starting at approximately $29 CAD, these items are molded to replicate common glassware and ceramic shapes.

Breakaway Kitchenware

Kitchen and dining scenes frequently call for breaking plates, bowls, and jars. Breakaway kitchenware includes mason jars, plates, and other household items, starting at approximately $30 CAD. These props allow domestic scenes to include dramatic moments without endangering performers or crew.

Breakaway Scientific and Laboratory Items

Productions set in laboratories, hospitals, or research facilities often require breakable scientific glassware. Breakaway scientific items include flasks, beakers, test tubes, and similar lab equipment, starting at approximately $50 CAD.

Specialty and Miscellaneous Items

Miscellaneous breakaway items cover specialty props such as fishbowls, vases, and other unique shapes that do not fit standard categories. These start at approximately $50 CAD. Additionally, products like breakaway realistic fake razor wire (from $215 CAD) serve niche production needs for action and thriller sequences where performers must interact with convincing but safe prop materials.

How to Choose the Right Breakaway Glass

Selecting the correct breakaway material for a given scene requires evaluating several production-specific factors. The wrong choice can result in unconvincing footage, wasted takes, or unnecessary safety risk.

Scene Requirements

Begin by defining exactly what needs to break, how it will be broken, and what the camera will see. A window that a stunt performer dives through has fundamentally different requirements than a wine glass thrown against a wall in the background. Map out the action choreography before selecting materials.

Performer Proximity

The distance between the performer and the breaking object is the single most important safety consideration. For stunts where a performer makes direct body contact with the prop—being pushed through a window, hit with a bottle—rubber breakaway glass is the appropriate choice. For objects thrown or broken at a distance from performers, standard resin breakaway glass provides a more visually convincing shatter.

Camera Distance

Close-up shots demand higher-quality materials with more realistic optical properties. Wide shots are more forgiving—the shatter pattern and debris field matter more than surface detail at distance. Budget accordingly: allocate premium materials to hero angles and standard materials to coverage and wide shots.

Number of Takes

Breakaway props are predominantly single-use items. If the director plans to shoot a scene from multiple angles or anticipates several takes for performance, the production must purchase enough breakaway items to cover every planned take plus contingency. A common guideline is to order 50% more pieces than the planned number of takes.

Environmental Conditions

Indoor and outdoor shooting environments affect breakaway material performance differently. Sugar glass is sensitive to humidity and may soften or become sticky in wet conditions. Resin-based products are more stable across temperature ranges but can become brittle in extreme cold. Wind can scatter lightweight fragments unpredictably outdoors, affecting both continuity and safety. Test all materials in conditions matching the shoot environment before the production day.

Safety Considerations

Breakaway glass is significantly safer than real glass, but it is not risk-free. Every production using breakaway materials should follow established safety protocols to protect performers, crew, and bystanders.

• Qualified special effects coordinator: A trained and experienced SFX coordinator should supervise all breakaway glass work on set. This person is responsible for testing materials, planning the gag, briefing performers and crew, and managing the execution of the effect.
• Eye protection: Performers should wear eye protection whenever possible. In many setups, safety glasses or goggles can be concealed from camera with careful framing and wardrobe choices. For shots where eye protection is not concealable, the SFX coordinator should use materials and techniques that minimize the risk of fragments reaching the performer's face.
• Area clearance: All non-essential crew should be cleared from the immediate area before any breakaway effect is executed. Establish a safety perimeter appropriate to the scale of the effect.
• First aid preparedness: A first aid kit and qualified safety officer should be present and accessible during any shoot involving breakaway effects. While serious injuries are rare with proper materials and techniques, minor scratches and abrasions can occur.
• Workplace safety regulations: Productions shooting in Ontario and across Canada must comply with applicable occupational health and safety regulations. Breakaway effects fall under workplace safety requirements, and productions should document their safety planning and briefings.
• Pre-shoot testing: Always test breakaway materials before the shoot day. Verify that the break pattern, fragment size, and debris scatter are consistent with the planned effect. Testing also reveals any material defects or storage-related degradation before they cause problems on a live set.

Frequently Asked Questions

Is breakaway glass safe for actors?

Yes, breakaway glass is safe for actors when used correctly under the supervision of a qualified special effects coordinator. Breakaway materials are specifically engineered to shatter without producing the sharp, dangerous edges associated with real glass. However, "safe" does not mean "zero risk"—minor scratches and abrasions are possible, and performers should wear concealed eye protection whenever feasible. The SFX coordinator should brief all performers on the planned effect, conduct rehearsals with the actual materials, and ensure appropriate safety measures are in place before executing the gag.

What is breakaway glass made of?

Breakaway glass is typically made from one of three material families: sugar-resin compounds (traditional sugar glass), synthetic resin formulations, or specialized rubber compounds. Sugar glass is made by heating sugar to a molten state and casting it into molds. Resin-based breakaway glass uses synthetic polymers that are cast or formed into sheets and shapes. Rubber breakaway glass uses flexible elastomeric materials for close-contact safety applications. Each material type has different optical properties, break characteristics, and environmental tolerances.

How much does breakaway glass cost?

Breakaway glass pricing varies by type and size. Flat sheets start at approximately $70 CAD. Breakaway bottles (wine, champagne, beer) start at approximately $30 CAD each. Breakaway cups and glassware start at approximately $29 CAD. Rubber breakaway glass starts at approximately $250 CAD. Structural items like foam bricks ($150 CAD) and cinder blocks ($160 CAD) are priced per piece. Productions should budget for multiples of each item to cover rehearsals, multiple takes, and contingency.

Can breakaway glass be used outdoors?

Yes, breakaway glass can be used outdoors, but environmental factors must be accounted for. Temperature extremes can affect material performance—sugar glass may soften in high heat or humidity, while resin-based products can become more brittle in extreme cold. Wind can scatter lightweight fragments unpredictably, affecting both continuity and safety zone planning. Always test materials in conditions matching the outdoor shoot environment, and adjust safety perimeters to account for wind-driven debris.

Where can I buy breakaway glass in Canada?

SPFX Supply, located in Toronto, Ontario, stocks one of the largest selections of breakaway glass and special effects props in Canada. Their inventory includes glass sheets, bottles, glassware, kitchenware, rubber glass, and structural breakaway materials. They offer local pickup in Toronto, shipping across Canada and the United States, and custom fabrication services. Contact them at 416-487-3211 or sales@spfxsupply.com.

How many breakaway items should I order for a shoot?

A standard guideline is to order at least 50% more breakaway items than the planned number of takes. For example, if a scene will be shot from three angles with two takes per angle, plan for at least nine pieces (six planned takes plus three contingency). Additional items may be needed for rehearsals, SFX coordinator testing, and unforeseen reshoots. Consult with your SFX coordinator during pre-production to determine exact quantities.
