VLT vs. IR: How to Choose the Best Window Film for Cars/Homes in Malaysia
Choosing window film can feel overwhelming—especially when different brands highlight various technical terms like VLT, IR rejection, and UV protection.
At Tint n’ Wrap, our goal is to help consumers make confident and informed decisions.
Here’s the complete guide you need before choosing a film for your car, home, or commercial building.
VLT Explained: Understanding Visible Light Transmission and Privacy
VLT measures how much visible light passes through a film, shown as a percentage:
70% VLT – very light, almost clear
50% VLT – moderate shading, natural look
20% VLT – darker, more privacy
5% VLT – very dark, maximum privacy
How to choose VLT
Front windows: Higher VLT for safe visibility
Rear windows: Lower VLT for privacy
Buildings: Mid-to-high VLT to keep natural light
Reminder: A darker tint does not mean better heat rejection.
Heat control mainly depends on IR rejection—not VLT.
IR Rejection: The Real Key to Reducing Heat and Lowering Energy Bills
Most of the heat you feel inside a car or room comes from infrared (IR) energy.
IR rejection tells you how well the film blocks this heat.
What high IR rejection does for you
Reduces cabin heat build-up
Keeps surfaces cooler
Improves comfort during long drives
Reduces dependency on air-conditioning
Recommended IR performance
≥ 80% IR rejection — noticeable improvement
90–95% IR rejection — premium-level heat reduction
The Haze Trade-Off: What Ultra-High IR Ratings Don’t Tell You
Some films claim extremely high IR performance, such as 97–99%.
While impressive on paper, this level of IR rejection may come with a trade-off:
Why haze increases at ultra-high IR levels
To achieve near-maximum IR blocking, manufacturers use:
Extra-dense nano-ceramic layers
Higher particle concentration
More complex stacking of film layers
These can cause light scattering, resulting in:
Slight haziness in bright sunlight
Reduced sharpness in visibility
A “milky” effect from certain viewing angles
What consumers should know
Ultra-high IR isn’t always the best option.
A good film maintains a balance between:
High IR performance
Clear visibility
Low haze
Stable color and appearance
99% UV Protection: Essential Safety for Health and Interior Longevity
Quality window film blocks up to 99% of harmful UV rays, which helps prevent:
Skin damage
Dashboard fading
Leather cracking
Interior discoloration
UV protection is most important for
Daily drivers
Families with children
Homes and offices with direct sun exposure
Quick Guide: Matching Window Film Specs to Your Needs in Malaysia
Use this quick guide:
| Your Goal | Recommended Film Specs |
|---|---|
| Reduce heat | High IR (≥ 80%) |
| Maximum comfort | IR 90–95% |
| Clear visibility | Mid-high VLT + low haze |
| Privacy | Low VLT (5–20%) |
| UV safety | 99% UV block |
| Home/office comfort | VLT 40–60% + high IR |
There is no single “best” film — only the film that matches your needs and environment.
