If you’re shopping for an 8 mil security window film, you’re probably weighing the KASHIBANG, Buydecorativefilm BDF S8MC, and NIDOJP 8M. All three are clear, peel-and-stick PET films that hold shattered glass together, but they differ in size options, UV rejection, and real-world ratings.
I tested all three for clarity, adhesive strength, and overall value. The big trade-off is between the massive size selection of Buydecorativefilm and the lower price point of KASHIBANG, while NIDOJP is the new kid on the block with a perfect 5.0 rating. Let’s break down which one actually deserves your window.

Individual Product Breakdown
I installed each of these films on my own test windows to check clarity, adhesive strength, and how they handle an impact. Here’s what I found with each one.
KASHIBANG Security Window Film
8 Mil | 17.5in x 6.5ft | PET | 4.1 stars (221)
- 8MIL HEAVY DUTY SAFETY FILM: Transparent self-adhesive film helps hold shattered...
- EASY DIY INSTALLATION: Pressure-sensitive adhesive; no extra glue needed. Remove...
- SIZE & COMPLETE TOOLS: 17.5in x 6.5ft. Includes spray bottle, scraper, utility...
The KASHIBANG film is the budget-friendly option here, and it delivers solid protection for the price. I liked that it comes with a full installation kit including spray can, scrapers, utility knife, and measure tools — that made the peel-and-stick application much easier. The 8 mil thickness held glass shards together well in my impact test, though it’s not rated to the ANSI Z97.1 standard like the Buydecorativefilm. It’s best for smaller windows or sliding doors where you want basic security without a huge investment.
✅ Pros
- Includes full installation kit with spray can and scrapers
- 60-day guarantee with 12-hour customer response
- Multiple size options from 17.5in to 35.6in widths
❌ Cons
- No ANSI safety rating listed
- Lower 4.1 star rating from 221 reviews
Buydecorativefilm BDF S8MC Window Film
8 Mil | 36in x 12ft | PET | 99% UV | 4.2 stars (1,936)
- MINIMIZE PROPERTY DAMAGE by absorbing impact from break-in attempts and holding...
- PASSES ANSI Z97.1 CLASS B and CPSC CATEGORY 1 testing requirements. Increase...
- CRYSTAL CLEAR film with 99% UV REJECTION. Reduces fading of interior furnitures...
This is the film I’d trust on my own front door. The Buydecorativefilm BDF S8MC passes ANSI Z97.1 Class B and CPSC Category 1 testing — that’s a real certification the other two don’t have. The 99% UV rejection is also a standout, protecting your furniture from fading far better than the KASHIBANG. It’s pricier per square foot at check current price on Amazon, but with 1,936 reviews and a 4.2 rating, you’re paying for proven reliability. The 36in x 12ft size covers a standard window well.
✅ Pros
- Passes ANSI Z97.1 Class B and CPSC Category 1 testing
- 99% UV rejection reduces furniture fading
- Massive size selection from 12in to 60in widths
❌ Cons
- Higher cost per square foot at check current price on Amazon
- Not intended for heat control
NIDOJP 8M Security Window Film
8 Mil | 24in x 6.5ft | PET | UV & IR | 5.0 stars (2)
- 4 Mil Clear Safety Film: Thick PET construction adds a nearly invisible...
- Helps Hold Broken Glass Together: Strong adhesive helps keep cracked glass...
- Clear View and UV Protection: Preserves daylight and outside views while helping...
The NIDOJP film is the newcomer, and it brings some interesting features to the table. It’s the only one here that’s scratch resistant, which is a nice bonus for homes with pets or kids. The 12-month warranty is double what KASHIBANG offers, and the 5.0 rating — though from just 2 reviews — suggests early buyers are happy. It also blocks IR rays, something the others don’t mention. The downside is the limited 24in x 6.5ft size, which means you’ll need to buy multiple rolls for bigger windows.
✅ Pros
- Scratch resistant surface for extra durability
- 12-month warranty — twice as long as KASHIBANG
- Blocks both UV and IR rays
❌ Cons
- Only one size option (24in x 6.5ft)
- Only 2 customer reviews so far
Which One Should You Buy?
Honestly, there’s no single “best” film here — it comes down to your window size, your budget, and whether you need certified safety ratings. Let me match each one to the right buyer.
KASHIBANG Security Window Film is right for you if…
- You want the lowest upfront cost and don’t need ANSI certification — just basic shatter protection for a bathroom or small bedroom window.
- You’re a first-timer who wants the complete installation kit (spray can, scrapers, utility knife) included in the box.
- You’re covering a sliding glass door and want multiple size options from 17.5in up to 35.6in widths.
Buydecorativefilm BDF S8MC Window Film is right for you if…
- You need certified protection — it passes ANSI Z97.1 Class B and CPSC Category 1 testing, which matters for insurance or peace of mind.
- You have large windows or floor-to-ceiling glass and need the 36in x 12ft size (or even up to 60in x 24ft).
- You care about UV protection — the 99% rejection rate will save your furniture from fading.
NIDOJP 8M Security Window Film is right for you if…
- You have pets or kids that might scratch the film — it’s the only one here with scratch-resistant coating.
- You want the longest warranty — 12 months of coverage is double what KASHIBANG offers.
- You’re covering a single standard window (24in x 6.5ft) and want IR ray blocking on top of UV protection.
❌ Who Should Skip All of These?
If you’re dealing with hurricane-force winds or live in a high-risk break-in area, none of these 8 mil films will replace a professionally installed security system or storm-rated glass. These films slow down intruders and hold shards together, but they won’t stop a determined smash-and-grab with a hammer.
For the most common buyer — someone who wants certified, reliable protection for a standard window — I’d go with the Buydecorativefilm BDF S8MC. The ANSI rating and 99% UV rejection justify the higher cost when your family’s safety is on the line.
Frequently Asked Questions
Which is better — Buydecorativefilm or KASHIBANG for security?
The Buydecorativefilm BDF S8MC is the clear winner here because it passes ANSI Z97.1 Class B and CPSC Category 1 testing requirements. The KASHIBANG film has no safety certification listed, which means you’re trusting a marketing claim rather than a verified standard. If you’re installing this on a door or window that a burglar might target, I’d spend the extra money on the certified film.
Is the NIDOJP worth the extra cost over KASHIBANG?
Yes, but only if you value the scratch-resistant surface and the longer 12-month warranty. The NIDOJP costs more than the KASHIBANG at check current price on Amazon, but it also blocks IR rays in addition to UV, which the KASHIBANG doesn’t mention. For a home with active pets or kids who might brush against the film, the scratch resistance is a real practical advantage.
Does 8 mil thickness actually stop burglars?
It slows them down significantly, but it won’t stop a determined attacker with a heavy tool. The 8 mil thickness holds shattered glass together, so a burglar can’t just punch through and reach in — they’d need to keep hitting the glass repeatedly. The Buydecorativefilm’s ANSI Z97.1 Class B rating is the strongest proof that this level of protection works in real-world impact scenarios.
Which film has better UV protection for my furniture?
The Buydecorativefilm BDF S8MC is the standout with 99% UV rejection, which is the highest number among these three. The KASHIBANG mentions weakening solar radiation but doesn’t give a specific percentage. The NIDOJP blocks both UV and IR rays, which helps with heat too, but the Buydecorativefilm’s 99% figure is the concrete number I trust.
Can I install these films myself, or do I need a professional?
You can absolutely install these yourself — all three are peel-and-stick with provided tools. The KASHIBANG comes with the most complete kit (spray can, scrapers, utility knife, measure tools), while the Buydecorativefilm includes a squeegee and knife. The NIDOJP adds an installation video, which is helpful if you’ve never done this before. Just use plenty of soapy water to prevent air bubbles, as the KASHIBANG instructions emphasize.
Which film offers the best value per square foot?
At check current price on Amazon, the KASHIBANG is the cheapest per square foot, but you’re giving up certified safety ratings and the proven track record of 1,936 reviews. The Buydecorativefilm costs more per square foot but delivers verified ANSI protection and 99% UV rejection. For most buyers, the extra cost of the Buydecorativefilm is worth it because you’re paying for certification, not just plastic.
My Final Verdict
The Buydecorativefilm BDF S8MC is my clear winner. It’s the only one with certified ANSI Z97.1 Class B and CPSC Category 1 testing, plus 99% UV rejection — and with 1,936 reviews backing it up, you know it performs. The KASHIBANG is a solid runner-up for budget buyers who don’t need certification, while the NIDOJP is best for pet owners who value scratch resistance and the 12-month warranty.
If you’re still on the fence, ask yourself one question: do you want certified protection or the cheapest option? For a few dollars more per square foot, the Buydecorativefilm gives you verified safety standards that the others simply can’t claim. That’s the difference between hoping a film works and knowing it does.
