The Proton e.MAS 5 has done something remarkable in Malaysia — it has made EV ownership mainstream. With prices starting from RM56,800 after rebate and over 3,000 units delivered in a single month, it has become the best-selling electric vehicle in the country and the second best-selling Proton model after the Saga. If you've just taken delivery, or have one on order, welcome to a growing club of early EV adopters reshaping Malaysian roads.
Now comes a question almost every new e.MAS 5 owner eventually asks: what's the right window film for my new EV?
It sounds simple. It isn't. Window film for an electric vehicle is a fundamentally different decision than for a petrol car — and getting it wrong can quietly cost you comfort, range, and peace of mind for years. This guide exists to help you think clearly about that choice.
The key points for Proton e.MAS 5 owners
1. EVs are sensitive to heat — better tint = less AC load = more range.
2. Some tints block GPS and 5G signals — a serious problem for connected EVs.
3. A cheap tint that bubbles in 2–3 years costs more in the long run than a quality
film installed once.
4. Non-metallic ceramic and multi-layer optical films are the safest bet for EVs.
Why e.MAS 5 owners need to think differently about tint
Most Malaysian drivers are used to thinking about window film in one dimension: how dark it looks. But for an EV like the Proton e.MAS 5, that's the least important question. There are three others that matter far more.
1. Your AC load directly affects your range
Your e.MAS 5 has a WLTP-rated range of 225 km (Prime) or 325 km (Premium). On paper, that's plenty for daily commuting. In reality, those numbers assume ideal conditions — and the Malaysian climate is anything but ideal.
Under direct midday sun, an un-tinted cabin can climb to 60–70°C in under 30 minutes. Cooling that cabin back down puts enormous load on your air conditioning, and in an EV, that AC load is drawn directly from your battery. Every kilometer of range spent cooling the cabin is a kilometer you don't get to drive.
A high-performance window film that rejects 95%+ of infrared heat can reduce cabin temperature significantly before AC even kicks in. For an EV, that translates to less battery drain and more effective daily range. It's one of those rare upgrades that pays back every single drive.
2. Your EV depends on signals you can't afford to block
The e.MAS 5 is a deeply connected car. It uses the Proton e.MAS app for charging, unlock, navigation, and diagnostics. It has wireless Apple CarPlay and Android Auto. The infotainment system pulls live traffic data. GPS must work reliably, not just for navigation, but for location-based features inside the Proton ecosystem.
Here's a quiet truth the industry doesn't like to advertise: many cheap window films — especially metallic-based ones — interfere with these signals. Metallic reflective layers block not just infrared radiation but radio frequencies too. GPS lock times get longer. Mobile reception inside the cabin gets weaker. 5G can drop to 4G. In some cases, even remote unlock starts becoming unreliable.
For a petrol car with a standard key, this matters less. For a connected EV like the e.MAS 5, it's a daily frustration waiting to happen.
3. Film longevity matters more when the car lasts longer
Proton backs the e.MAS 5 with a 6-year unlimited-mileage vehicle warranty and 8-year (or 160,000 km) battery warranty. You are likely to keep this car for a long time. That makes long-term film durability — not just sticker price — the right way to think about value.
A real Proton e.MAS 5 story
One of our more recent e.MAS 5 customers is worth telling about, because his reasoning captures everything above in a way no spec sheet can.
"My last car, I paid more than RM 2,000 for window tint. Looked fine for the first year. By year three, it was starting to bubble. And honestly? It never really felt cool. I don't want to repeat that. Not on this car." — e.MAS 5 owner, Selangor
When he came to a Vertex Authorized Service Centre to ask about options for his new e.MAS 5, he had one specific concern that came up before heat, before looks, before anything else.
"I just don't want any issues with the signal. This car is connected to everything — the app, the maps, the charging network. If the tint blocks the GPS even a little, it's going to drive me crazy."
After going through the options with our specialist, he chose the most premium film in our range: Aurora, our Multi-Layer Optical film. Not because it was the most expensive. Because of what it doesn't do.
Aurora uses over 200 optical layers to manage heat through wavelength reflection, not metallic reflection. It contains no metallic layers at all. That means infrared heat is rejected up to 99%, but GPS, 5G, 4G, Wi-Fi, Bluetooth and RFID signals pass through completely unimpeded. The reason he chose Aurora wasn't vanity. It was engineering that matched what his EV actually needed.
Aurora — a single sample under studio lighting. No metallic reflection. No signal interference.
Comparing your window film options for e.MAS 5
Not every e.MAS 5 owner needs to go to Aurora. Your choice depends on how you drive, what you care about, and how long you plan to keep the car. Here's an honest comparison of the four Vertex options, thinking specifically about an EV owner's needs.
| Oasis | Glacier | Canopy | Aurora | |
|---|---|---|---|---|
| Category | Nano Ceramic | Sputtered Ceramic | Safety Reinforced | Multi-Layer Optical |
| IR Rejection | ~80% | ~95% | ~95% | 95–99% |
| UV Block | 99% | 99% | 99% | ≥99% |
| Signal-Friendly | Yes | Yes | Yes | Yes |
| Warranty | 5 years | 7 years | 7 years | 10 years |
| Best for | Budget-minded EV owners wanting genuine ceramic protection | Performance-minded drivers wanting strong heat rejection | Drivers prioritising safety and structural integrity | Those who want the best of everything, for the long haul |
All four films are non-metallic and fully signal-friendly — so your e.MAS 5's GPS and connectivity are safe regardless of which you choose. The real differences are in how much heat they reject, how long they last, and how they look.
The cost trap Malaysian drivers keep falling into
The customer story above touches on something we see constantly: drivers paying RM 2,000+ for a film that looks fine for a year, then starts bubbling, hazing, or peeling by year three. The film stops rejecting heat properly long before it starts looking ugly. By the time the visible damage shows, the drive has been uncomfortable for months.
When that film is eventually removed and replaced, total cost easily exceeds RM 4,000 — sometimes more if the old adhesive has damaged the glass or stained the rubber seals.
A quality film installed once, backed by a proper warranty, at a Vertex Authorized Service Centre costs less across its real lifetime. That's not a sales pitch — it's just basic math on a durable good.
Practical advice: what to ask before tinting your e.MAS 5
- Is this film metallic or non-metallic? For a connected EV, non-metallic (ceramic or optical) is the only safe answer.
- What's the IR rejection percentage — and is it verified? Marketing numbers can be misleading. Ask for documented specifications.
- What warranty is provided — and where can I honour it? A 5–10 year warranty that's only valid at one shop is worth less than a 5-year warranty honoured nationwide.
- Will you test-fit a sample before installation? A proper studio will let you see and feel the film before committing.
- How long has the installer been doing this specific film? Experience with the specific product matters more than years in the business.
