Best for a small smooth pane
If the glass is smooth, flat, and no wider than 30 cm, three 4 mil rolls match the size. Mgood at 30 × 200 cm was about £11.59, with 4.0 from 467 ratings. DARUITE at the same size was about £11.89, with 4.0 from 1,935 ratings. Qualsen was about £12.57, with 3.8 from 52 ratings. Each sheet is about 0.6 square metres.
Mgood’s widths share one review pool, and so do DARUITE’s. Many comments describe privacy or blackout, so the score is not a report on clear film on a smashed side-light. DARUITE does not mark ultraviolet protection. Qualsen’s pool includes a static-cling comment, and the listing says to avoid rough or frosted glass. Use Mgood only if you accept that mixed pool and you need about two metres of 30 cm film. If the pane is wider than 30 cm, do not join two strips, because a seam is a gap in the sheet.
Best for a wider pane
Measure the pane, including any curve, before you choose a wider roll. Mgood and DARUITE at 44.3 × 200 cm, sold in the titles as 44 cm, are the wider sheets from those same review pools. Shackcom at 44 × 300 cm was about £13.99, with 3.8 from 1,157 ratings. Its bullets say 4 mil, the material field says vinyl, and it suits several small panes, such as a greenhouse, rather than one window. That area at that price is why it is the best value.
AWKAQUN is about 76 cm by 5 m, about 3.8 square metres, at about £29.99, and the title states no mil thickness. Reviewers call it very thin, some found no adhesive, and patterned or curved glass was a miss. A 44 cm sheet still leaves a 70 cm kitchen pane short, so use AWKAQUN only when that glass is flat and the film sticks. What the mil labels measure is on the 4 mil or 8 mil security window film page.
The roll that states a test
BDF S4MC is the only listing here with a safety test on the page, which is why it is the top pick. The roll is 91 cm by 7.32 m, about 6.7 square metres, at about £66.51, with 4.3 from 424 ratings, mostly written in the United States. It says 4 mil and 100 micron, and it names ANSI Z97.1 Class B and CPSC Category 1, not BS EN 12600 or BS EN 356. It states 99% UV rejection, which the narrow rolls do not claim. A sheet this wide is a two-person fit.
Choose BDF when you can use most of that roll on flat panes and you want the US class in writing. It is not a UK certificate. 3M says S2400, a trade film outside this set, is not bulletproof and does not stop an intruder, and the same limit applies here. For a single pane of about 0.6 square metres, skip it. Qualsen 8 mil at about £19.98, with 3.4 from five ratings, is a thicker 30 cm roll and names no test.
Who should skip the set
Leave every roll if you want privacy or blackout film, a PAS 24 window, or a current BS EN 12600 or BS EN 356 certificate. The Metropolitan Police advise laminated glass or security film on reachable windows, and they still expect you to use the locks. What film will not stop is on the security window film and burglary page. Also leave the set for rough, frosted, wired, cracked, overhead, or already laminated glass. Qualsen warns off rough and frosted glass, and an AWKAQUN review reported a miss on patterned glass.
A hand that can reach a handle needs laminated glazing, not a roll at about £12. A specialist fit is a different purchase from these listings. Match the pane: Mgood under 30 cm, a wider sheet or Shackcom up to about 44 cm, AWKAQUN only if the glass is flat and the film sticks, and BDF only for the stated US test on a large roll. Otherwise buy none of them.
Common questions
What is the best security window film for one small pane?
For one smooth pane no wider than 30 cm, Mgood 4 mil at 30 × 200 cm is the matching listing. Captured amazon.co.uk figures show about £11.59 and 4.0 from 467 ratings. DARUITE at about £11.89 has the same 4.0 from a larger pool, and Qualsen at about £12.57 has 3.8 from 52 ratings, including a static-cling comment. Those pools also describe privacy and blackout film. If the pane is wider than 30 cm, a narrow roll is the wrong sheet.
Which roll covers a pane wider than 30 cm?
Mgood and DARUITE each list a sheet about 44.3 cm wide and 200 cm long, so they cover glass a 30 cm roll would split. Shackcom is 44 × 300 cm at about £13.99 and is the best value for several small panes rather than one wide window. AWKAQUN, about 76 cm by 5 m at about £29.99, covers a flat pane wider than 44 cm if the film sticks. Reviewers have called it very thin, and some found no adhesive.
Which listing actually states a safety test?
BDF S4MC is the only listing in this set that names a safety test, and it is the top pick for that reason. It cites ANSI Z97.1 Class B and CPSC Category 1 on a 4 mil sheet of 91 cm by 7.32 m, captured at about £66.51 with 4.3 from 424 ratings. That is a US line, not BS EN 12600 and not BS EN 356. Written reviews in the capture are mostly from the United States. If you need a UK certificate, this listing does not supply one.
Is the highest star rating the best shatter film?
No. BDF’s 4.3 from 424 ratings is the highest score in the set, and Mgood and DARUITE sit at 4.0 in pools that also describe privacy and blackout film. Those pools cover more than one width, so the number is not a verdict on the clear 30 cm roll. The better listing is the one whose width covers your pane in one piece and whose wording matches a clear shatter film.
Should I buy the 8 mil Qualsen roll because it is thicker?
Not if you want a tested film. Qualsen 8 mil is 30 × 200 cm, captured at about £19.98 with 3.4 from five ratings, and the listing names no safety test. A thicker label does not make the sheet ANSI Z97.1 or BS EN 356. The roll is still only 30 cm wide, so a wider pane is the wrong job.
Who should skip every roll in this set?
Skip every roll here if you want privacy or blackout film, a PAS 24 window, or a current BS EN 12600 or BS EN 356 certificate. Skip them on rough, frosted, wired, cracked, overhead, or already laminated glass, and where a hand can reach a handle. The Metropolitan Police still expect you to lock a reachable window. 3M says even its S2400 trade film is not bulletproof and does not stop an intruder.
Is a professional security film the same purchase as these rolls?
No. A professional security film is specified and fitted as a system, and the installer is part of what you pay for. These rolls are amazon.co.uk sheets you fit yourself on smooth interior glass. BDF S4MC is the only one that states a US safety test, and that test is not a British Standard. If a surveyor, insurer, or landlord has named a standard, buy to that document.
