3M Safety Film in Four Numbers
The published 3M figures that define safety and security film.
Thickness
4–8 mil
From Safety S40 at 4 mil to Ultra S800 at 8 mil. Thickness is the specification.
Visible light
86–88%
Clear grades pass 86 to 88 percent of visible light, so the glass still looks untreated.
UV blocked
99%+
Clear safety films block more than 99 percent of UV on 3M data.
SHGC
0.80
Solar heat gain coefficient of clear Ultra S800. It is a safety film, not a heat film.
From 3M technical data sheets for Safety S40, S70, Ultra S600 and Ultra S800 on quarter-inch clear glass.
3M Safety and Security Film: What It Does
3M safety and security film is a clear polyester film, 4 to 8 mil thick, bonded to existing glass so that broken glass stays in one sheet instead of falling as shards. Grades are tested to ANSI Z97.1, and the thicker Ultra films to storm and blast criteria when anchored to the frame. It does not make glass unbreakable, and on its own it does little for heat.
3M safety and security film is a clear, thick polyester film bonded to the inside of existing glass. When the pane breaks, the fragments stay attached to the film instead of falling or flying as loose shards. That is its job: it changes what happens after glass breaks. It does not make glass unbreakable.
3M sells the range by thickness. Safety S40 (4 mil) and Safety S70 (7 mil) are tested to ANSI Z97.1 Class B for human impact. Ultra S600 (6 mil) and Ultra S800 (8 mil) are tested to ANSI Z97.1 Class A, and Ultra S800 has also been tested against windborne debris and blast criteria when anchored with 3M Impact Protection Attachment. Clear grades pass 86 to 88 percent of visible light, so the glass still looks like glass. See safety film for homes and commercial safety film for grade-by-grade advice.
Why Glass Safety Matters in Dubai
Dubai buildings use a lot of glass: floor-to-ceiling villa windows, sliding patio doors, glass balustrades and shopfronts. Where a pane sits beside or above people, the injury comes from falling and flying glass rather than from the break itself. Safety film is fitted where that risk is highest: patio and balcony doors, low glass near children and pets, ground-floor and entrance glazing, and high-level glass over walkways.
Clear safety films also block more than 99 percent of UV on 3M data, which slows fading. They do very little for heat: 3M lists a solar heat gain coefficient of about 0.80 for clear Ultra S800. Where heat is also a problem, a combined film such as Ultra Prestige S70 adds solar control to the safety layer.
How Safety Film Is Fitted
The glass is surveyed first: type, thickness, pane size, frame and edge condition. The pane is deep-cleaned and the film applied wet from inside, squeegeed flat and trimmed to the frame edge. This daylight application holds fragments together.
Where the goal is delaying a break-in or resisting storm or blast loads, the filmed glass also has to be anchored to the frame, either by a structural sealant bead such as 3M Impact Protection Attachment or by a mechanical profile. Without it, the whole filmed sheet can be pushed out of the frame in one piece.
What to Check Before You Buy
- The grade: the exact 3M product and thickness written on the quote.
- The standard: which test it passed, such as ANSI Z97.1 Class A or Class B.
- The attachment: daylight application only, or anchored to the frame.
- The glass: confirmation that the film suits your glass type and shading.
- The warranty: the written terms that apply to your installation.

3M Safety Film: Published Mechanical Data and Standards
What safety film is and what it is not
Safety and security film is a thick polyester laminate bonded to the glass with a pressure-sensitive adhesive. When the pane breaks, the film holds the fragments together instead of letting them travel. That is the entire mechanism, and it is worth being precise about it, because the two most common expectations of this product are both wrong.
- It does not make glass unbreakable. Glass still breaks. The film changes what happens next.
- It does not, on its own, hold the glass in the frame. An intruder pushing on filmed glass can push the whole sheet out of its rebate unless an attachment system anchors the film to the frame. This is the single most overlooked part of a security glazing specification.
What it does do is remove flying and falling glass from the equation, and that is the injury mechanism in almost every glass incident in an occupied building, from a storm to an impact to a blast event.
Thickness is the specification, and it is measured in mils
Safety film is sold by thickness and the difference between grades is not marginal. 3M publishes a nominal 8 mils for Scotchshield Ultra S800, 9 mils including adhesive, against the 1.5 to 2 mil construction typical of a solar control film. The published mechanical figures for that product on quarter-inch clear glass:
| Property | Published value | What it governs |
|---|---|---|
| Nominal thickness | 8 mils film, 9 mils with adhesive | How much energy the film can absorb before it fails |
| Tensile strength | 33,000 psi machine direction, 30,000 psi transverse | Resistance to being pulled apart |
| Break strength | 265 lb/in machine direction, 240 lb/in transverse | The load the sheet carries before rupture |
| Elongation at break | 140% machine direction, 130% transverse | How far it stretches while holding fragments |
| Tear resistance, Graves | 37 lbs both directions | Resistance to a tear propagating from a puncture |
| Peel adhesion to glass | 6 lbs/in typical, ASTM D-1044 | How well the film stays bonded under load |
| Visible light transmission | 88% | It is optically clear, not a tint |
| Ultraviolet transmission | Less than 1% over 300 to 380 nm | Fading protection comes free with it |
| Solar heat gain coefficient | 0.80 | Minimal solar benefit, this is not a heat film |
Read the last two rows together and the design decision becomes clear. Clear safety film blocks essentially all ultraviolet, so fading protection comes with it, but at a solar heat gain coefficient of 0.80 it barely touches heat. Where a building needs both fragment retention and solar control, the answer is a combined product such as the Scotchshield Ultra Prestige or Ultra Night Vision constructions, not a clear safety film plus hope.
The standards that mean something
3M references a specific set of test standards for this product family, and they are worth knowing because they are how a specification is written rather than argued:
- ANSI Z97.1 and impact safety glazing tests, for human impact on a glazed opening.
- ASTM E-1886 and E-1996, for windborne debris and cyclic pressure, which is the storm and large-missile case.
- ASTM F-1642 and GSA-TS01-2003, for blast hazard mitigation, which is how glazing performance is classified for a blast event.
- ASTM D-882, D-1044 and D-2582, for the tensile, adhesion and tear figures in the table above.
A quote that cites a standard has to cite the tested assembly, not just the film. A film tested in a laboratory frame with an anchoring system does not carry that result into a building where it is simply applied to the glass surface and trimmed at the edge.
Attachment systems: the part that gets left out
There are three broad ways the filmed glass meets the frame, and they perform very differently.
- Daylight application. Film trimmed to the visible edge of the glass. Fragment retention only. The sheet can still leave the frame.
- Wet glazed. A structural silicone bead bonds the film edge to the frame, so the sheet stays anchored under load.
- Mechanical attachment. A profile or batten physically clamps the filmed glass into the frame. The highest performance and the most intrusive.
Which one is appropriate depends on what the glazing is being protected against and what the building will accept visually. It belongs in the specification at the start, because retrofitting an attachment system later means going back to every opening.
Where it is specified in Dubai
Ground-floor retail and street-facing glazing, schools and clinics, server rooms and cash areas, villa glazing at ground level, and high-level glazing where a failure would drop glass into an occupied space below. The common thread is not crime. It is that a pane failing above or beside people is the hazard, whatever caused it.

Where Safety and Security Film Is Specified
Safety film is specified against a threat and a glazing type, not bought as a generic upgrade. These are the four cases it is most often written into in Dubai.
Wind, Debris and Accidental Impact Applications
For glazing exposed to accidental impact, wind-borne debris or other breakage hazards, the relevant property is what happens after the glass fractures. A correctly specified safety-film system can help keep fragments attached to the filmed pane and reduce the amount of loose glass released into the occupied area.
Windstorm performance is application-specific. 3M notes that certain windstorm applications require Safety & Security Window Film together with the Impact Protection Attachment (IPA) Sealant. Glass type, pane size, frame construction, pressure, debris and installation details all affect performance, so this should not be presented as a generic hurricane-proof upgrade.
Specialist Blast-Mitigation Applications
Blast-mitigation is a specialist commercial or government-facility application, not a general residential claim. 3M states that references to explosions or blasts apply only to commercial and non-educational government facility applications, and the system must be selected from the current technical guidance.
The objective is to help reduce hazards from flying glass fragments under specified conditions. Performance depends on the film, glass, frame, attachment system, distance and characteristics of the event and the building construction. A normal safety-film installation should not be advertised as blast-proof or explosion-proof.
Glass Doors, Partitions and Pool-Area Glazing
Doors, partitions and pool-area glazing are examples where accidental glass breakage can create an immediate fragment hazard. Safety film can be considered as part of a glazing-safety assessment when the existing glass is compatible and the intended benefit is to help keep broken fragments associated with the filmed pane.
Film does not automatically convert non-compliant glass into code-compliant safety glazing, and pool barriers or balustrades can be subject to specific structural and safety requirements. These applications should be checked against the actual glass specification and local project requirements before film is proposed.
Balustrades, Facades and Large Glazing Areas
Large glazed areas, balustrades and facade elements require particular care because the glass may have a structural or barrier function beyond simply closing an opening. Safety film can improve fragment retention on compatible glazing, but it should not be assumed to replace laminated safety glass, structural interlayers, handrail systems or code-required barrier performance.
For these applications, the installer should identify the glazing make-up and understand the design objective before recommending film. Pane dimensions, glass thickness, edge support, frame system and exposure all influence the appropriate film and attachment detail.

Three Safety Film Myths
Three claims about security film that are not true.
Myth
Safety film makes glass shatter-proof
Fact
Glass still breaks. The film keeps the pieces together so they do not fall or fly.
Myth
Film alone stops a burglar
Fact
It slows entry. Without an attachment system, the filmed sheet can be pushed out of the frame whole.
Myth
Clear safety film cuts air-conditioning bills
Fact
Clear Ultra S800 has a solar heat gain coefficient of about 0.80. For heat and safety together, a combined film such as Ultra Prestige S70 is used.

Frequently Asked Questions About Safety and Security Film
Does safety film stop someone breaking in?
It holds fragments together so the glass does not shatter open, which slows and complicates an entry attempt. It does not make glass unbreakable, and without an attachment system anchoring the film to the frame the whole sheet can be pushed out of its rebate. Any security claim depends on the full assembly, not on the film alone.
How thick is 3M safety and security film?
3M publishes a nominal 8 mils for Scotchshield Ultra S800, 9 mils including adhesive. For comparison, a typical solar control film is 1.5 to 2 mils. Thickness is the primary specification for this product category.
Does safety film also reduce heat?
Clear safety film barely does. 3M publishes a solar heat gain coefficient of 0.80 for Ultra S800 on quarter-inch clear glass, against 1.0 for unfilmed glass. It does block ultraviolet, with less than 1 percent transmission over 300 to 380 nanometres. Where both fragment retention and solar control are needed, a combined safety plus solar product is specified instead.
Is safety film visible once installed?
Clear safety film transmits 88 percent of visible light, so it reads as clear glass. Where an attachment system is used, the silicone bead or mechanical profile at the frame edge is visible, which is a design decision to take early.
What standards does safety film meet?
3M references ANSI Z97.1 for impact safety glazing, ASTM E-1886 and E-1996 for windborne debris, ASTM F-1642 and GSA-TS01-2003 for blast hazard mitigation, and ASTM D-882, D-1044 and D-2582 for the mechanical properties. A standard applies to a tested assembly including how the film is anchored, not to the film in isolation.
Can safety film be applied to any glass?
It depends on the glazing. Thick absorptive films change the thermal behaviour of a pane, and toughened, laminated and double-glazed units each respond differently. The glass type, thickness, unit construction and shading pattern are assessed before the product is specified.
How long does safety film last?
Service life depends on exposure, whether it is interior or exterior applied, and how the glass is cleaned. Warranty terms vary by product, market and installer. Confirm the term and what it covers before the work, and keep the documentation with the building records.
