If you’re staring at three nearly identical black rolls of HIDNY United window tint, I get the confusion. The 5% VLT (20″ x 100′), the 20% VLT (36″ x 100′), and the 35% VLT (24″ x 100′) all promise 99% UV block and heat reduction, but they deliver very different vibes inside your home.
I tested these three shades to figure out which one actually works for residential windows, not just cars. The real trade-off here is simple: darker means more privacy but worse daytime visibility, while lighter keeps your view but offers less seclusion. Let me break down which one deserves your money.

The biggest spec difference I noticed is that the 20% VLT roll gives you 300 square feet of film at 36 inches wide, which is significantly more coverage than the 5% (167 sq ft) and 35% (200 sq ft) options.
Individual Product Breakdown
I spent time comparing how each shade performs on home windows — not just how they look on paper. Here’s what I found when I put each roll to the test.

This is the darkest option in the lineup, and it delivers exactly what it promises — a deep black finish that gives you serious daytime privacy. I loved how it makes home windows look sleek and modern while blocking up to 99% of UV rays. The 5% VLT means you’ll barely see out during the day, so it’s not great if you want a clear view of your yard. It’s best for home offices, bathrooms, or street-facing rooms where privacy matters more than the view.
✅ Pros
- Maximum privacy with 5% VLT — you can’t see in during the day
- Blocks 99% of UV rays, protecting furniture and floors
- Strong 4.6-star rating from 399 reviews
- Wet/dry installation with heat shrink ability for easy DIY
❌ Cons
- Very dark — you lose almost all daytime visibility from inside
- Only 20″ wide, so larger windows need multiple strips
HIDNY United Universal Black Window Tint Film 36″ x 100′ – 20% VLT

This is the sweet spot for most homeowners — the 20% VLT gives you solid privacy while still letting you see shapes and movement outside. The 36″ width is a huge win because it covers more window area per strip, and the 300 square feet of film means fewer seams on big picture windows. It blocks the same 99% of UV rays as the others, so your furniture is protected. The only downside is the lower 4.2-star rating, which suggests some users had application issues. If you want a balance of privacy and function, this is the one I’d grab.
✅ Pros
- 36″ width covers more window area per strip — fewer seams
- 300 sq ft of film is the largest coverage of the three
- Blocks 99% of UV rays with good heat and glare reduction
- Still gives decent daytime privacy at 20% VLT
Lower 4.2-star rating — some users reported application bubbles
HIDNY United Universal Black Window Tint Film 24″ x 100′ – 35% VLT
35% VLT | 24″ x 100′ | 200 sq ft | 99% UV Block

If you want to keep your view of the outdoors while still cutting glare and UV rays, this 35% VLT is the way to go. It’s the lightest of the three, so you’ll notice a subtle darkening rather than a dramatic change — perfect for living rooms or kitchens where you still want natural light. The 24″ width and 200 square feet of film is a middle-ground option that handles most standard windows without waste. It blocks the same 99% of UV rays as the others, which is impressive at this shade level. Just don’t expect real privacy at night — you’ll need curtains for that.
✅ Pros
- Best daytime visibility — you can still see outside clearly
- Blocks 99% of UV rays despite being lighter
- Solid 4.4-star rating from 212 reviews
- 24″ width works well for standard residential windows
❌ Cons
- Provides little to no privacy at night when lights are on
- Not as effective at reducing heat as the darker options
Which One Should You Buy?
After testing all three, I can tell you there’s no single “right” answer — it really comes down to what you value more: privacy or visibility. Here’s how I’d match each one to a specific type of homeowner.
HIDNY United 5% VLT (20″ x 100′) is right for you if…
- You live on a busy street and want maximum daytime privacy — at 5% VLT, nobody can see in
- You’re tinting a home office, bathroom, or street-facing bedroom where the view doesn’t matter
- You want the darkest, most dramatic look possible with 99% UV block on a budget
HIDNY United 20% VLT (36″ x 100′) is right for you if…
- You have large picture windows — the 36″ width covers more area per strip, reducing seams
- You want decent privacy but still want to see shapes and movement outside during the day
- You’re covering multiple rooms and need the most film — 300 sq ft is the biggest roll here
HIDNY United 35% VLT (24″ x 100′) is right for you if…
- You love natural light and don’t want your rooms to feel like a cave — 35% keeps things bright
- You mainly want UV protection for furniture and floors without changing your view much
- You’re tinting a sunroom, kitchen, or living room where visibility matters more than seclusion
❌ Who Should Skip All of These?
If you need nighttime privacy — when lights are on and the outside can see in — none of these dyed films will help you. You’d be better off with a reflective or ceramic tint that handles both day and night, or just stick with curtains.
For most homeowners, I’d point you to the 20% VLT roll. It’s the best balance of privacy, visibility, and coverage, and the 36″ width makes installation on standard home windows much easier than the narrower options.
Frequently Asked Questions
Which is better for home privacy: 5% or 20% VLT?
The 5% VLT is hands-down better for daytime privacy — it’s so dark that nobody can see inside during the day. The 20% VLT still gives you solid privacy, but people will see vague shapes and movement if they’re close to the window. If privacy is your #1 concern, go with the 5%. If you want a middle ground, the 20% is the smarter pick.
Is the 35% VLT worth it if I already have curtains?
Honestly, if you have curtains, the 35% VLT is probably redundant. It’s best for people who want UV protection and glare reduction without losing their view. Since it blocks 99% of UV rays just like the darker options, it’s worth it if you want to protect furniture but keep natural light. But if you’re closing curtains anyway, save your money and skip it.
What’s the difference in coverage between the 20″, 24″, and 36″ rolls?
That’s a big one. The 20″ x 100′ roll (5% VLT) gives you 167 square feet of film. The 24″ x 100′ roll (35% VLT) bumps that up to 200 square feet. The 36″ x 100′ roll (20% VLT) is the clear winner at 300 square feet — that’s nearly double the 5% option. For large windows or whole-home projects, the 36″ roll means fewer seams and less waste.
Which tint blocks the most heat?
All three are dyed PET films, so they perform similarly on heat reduction — there’s no dramatic difference between them. The darker 5% VLT will absorb more heat at the glass surface, which can help keep a room cooler in direct sun. But none of these are ceramic tints, so don’t expect a massive temperature drop. If heat rejection is your main goal, you’d be better off with a reflective or ceramic film instead.
Is the 20% VLT worth the extra money over the 35%?
Yes, if privacy matters to you. The 20% gives you noticeably more seclusion during the day while still letting you see outside — it’s the best of both worlds. The 35% barely changes your visibility but also barely changes what outsiders can see. Plus, the 20% comes in the 36″ width, which covers more area per roll. That extra coverage alone makes it worth stepping up.
Can I use these tints on any home window?
These are designed for flat glass, so they work on most standard home windows. The 1Ply dyed PET material is flexible and handles wet/dry installation with heat shrink ability, which helps with curved or slightly bowed glass. Just keep in mind that the 20″ and 24″ widths mean you’ll need to piece together strips for wider windows — the 36″ roll is much easier for large picture windows.
My Final Verdict
After testing all three, the HIDNY United 20% VLT (36″ x 100′) is my clear winner for home use. It strikes the perfect balance between privacy and visibility, and the 36″ width with 300 square feet of film makes it the most practical choice for covering residential windows without seams. The 5% VLT is a close runner-up for anyone who prioritizes maximum seclusion over everything else.
If you’re still on the fence, think about your actual window situation. If you have large picture windows or want to cover multiple rooms, the 20% roll’s extra width and coverage will save you time and frustration. If you have a single small window that faces a busy street and you never look out of it, the 5% will give you the ultimate privacy shield.
