Security window film: slow break-ins through glass

Most break-ins come through a door or window, and the glass is usually the quickest way in. Security film holds a broken pane together in the frame, so a few quiet seconds becomes a slow, noisy struggle. Our top specification is 3M Ultra S800, anchored into the frame. For homes, shops and offices across Sussex, Kent, Surrey and London.

The problem

Glass is the weak point

Locks, bolts and alarms have all got better. Ordinary glass hasn’t. A pane in a patio door or shop window can be broken with one strike, and once it’s gone the way in is wide open.

Opportunist burglars want to be in and out quickly and quietly. They pick the easiest target on the street, and a window that can be smashed in seconds, round the back and out of sight, is exactly that.

Ordinary glass

  • Breaks with a single strike
  • Falls out, leaving an open hole
  • Quick and fairly quiet
  • Sharp shards fly into the room

With security film

  • Cracks but stays in the frame
  • Has to be hit again and again
  • Slow, noisy and hard work
  • Broken pieces stay stuck to the film
How it works

Buying you time when it matters

Security film is a thick, tough, optically clear layer bonded to the inside of your glass with a strong adhesive.

1

The glass is hit

The pane cracks as normal. Film doesn’t make glass unbreakable, and we won’t tell you it does.

2

The film holds it

Instead of falling out, the broken glass stays stuck to the film and in the frame, still acting as a barrier.

3

Time and noise

Getting through means hitting it over and over. That draws attention, sets off alarms and gives you, your neighbours or the police time to react. Most opportunists give up.

Options

A film for every budget and every risk

We’ll look at your glazing, how exposed it is and what else you want from it, then recommend the right film. We fit 3M and other leading brands, so there’s an option to suit most budgets.

Our top specification

3M Ultra S800, anchored into the frame

3M’s premium security film: a 200-micron, multi-layer film tested to the European standards for impact safety (EN 12600) and resistance to attack (EN 356). We anchor it into the window frame with an edge retention system, so when the glass is struck the whole pane stays held in the frame instead of falling through.

  • Best for patio doors, bi-folds, ground-floor glass and high-risk homes
  • Virtually invisible once fitted, and blocks over 99% of UV
  • Backed by 3M’s manufacturer warranty

Security film without anchoring

Thick, clear security film fitted to the glass alone. It holds broken glass together and makes forced entry slower and noisier, at a lower cost than an anchored system.

Safety film

A thinner film that stops glass shattering into sharp pieces. The budget choice for accident safety and bringing glazing up to safety rules.

Security plus solar or privacy

Combined films that slow break-ins and also cut heat and glare, or stop people seeing in, all in one layer.

How well any security film performs depends heavily on fitting, especially at the edges, which is where 30 years of experience counts.

Security film on a forecourt store

At the Morrisons Daily on the Wivelsfield forecourt, we fitted security film to the big windows that run down the side of the building. It’s a lot of ground-level glass on a busy road, open late, so it was the obvious place to slow down anyone trying to get in.

The job was for repeat client TAP Retail, and alongside the security film we also fitted solar film and the store graphics at their Wivelsfield and Tonbridge stores.

Usually done in a day

Film goes onto your existing windows and doors. A typical house is finished in a day.

Discreet

For high-profile homes and businesses we work quietly and are happy to sign an NDA.

Security film works best alongside good locks, an alarm and lighting. It’s the part that slows someone down while everything else does its job.

Security film questions

No film makes glass unbreakable, and we won’t pretend it does. What it does is hold the broken glass together in the frame, so getting through takes repeated blows instead of one. That costs an intruder time and makes a lot of noise, which is exactly what an opportunist doesn’t want.

Unanchored film is fitted to the glass only, so it holds the broken pieces together but the whole pane can still be pushed out of the frame. With an anchored system, such as 3M Ultra S800 with an edge retention system, the film is also fixed into the frame, so the pane stays in place and is much harder to get through.

Our top specification is 3M Ultra S800, anchored into the frame. We also fit security and safety films from other leading manufacturers, so we can match the film to your budget and how exposed the glass is.

Clear security film is optically clear, so your windows look the same. If you’d also like privacy or less heat, we can fit a tinted, mirrored or frosted security film instead.

Start with the glass that’s easiest to reach and hardest to see from the street: patio and French doors, back and side windows, glazed back doors, and any pane next to a lock or handle. For shops, the shopfront and door glass come first.

Yes. We fit it to the inside pane in most cases. We’ll check your glazing when we quote, as a few sealed units need a particular film.

Yes. The same film that slows an intruder stops broken glass falling out in sharp pieces, so it also protects people from injury if a pane is hit by accident or in a storm.

Yes. Combined films give you the strength of security film with heat and glare control, or privacy, in one layer.

No. We work around your opening hours, including early mornings, evenings and weekends, so you can keep trading.

Professionally fitted security film typically lasts many years. We give a 12-month workmanship guarantee, and the film carries the manufacturer’s warranty.
