If you walk past a car with almost black windows, you’re probably looking at a 5% tint. That number means only 5% of light can pass through the glass – the rest is blocked by the film. The result is a dark, sleek look that many owners love because it hides the interior and adds a sporty vibe.
But a darker film isn’t just about looks. It cuts glare, reduces heat, and gives a little extra privacy. On hot summer days, a 5% film can make the cabin feel cooler, and it can protect seats from UV damage. The trade‑off is reduced visibility at night, especially if you drive on poorly lit roads.
In the UK, the law is clear: front side windows must let at least 70% of light through, and the rear side windows need a minimum of 30%. A 5% film exceeds those limits for the front and rear side windows, so it’s illegal to use on those panes. The only place you can legally fit a 5% tint is the rear windscreen (the back window) or the rear doors, as long as the front windows stay clear.
If you get caught with illegal tint, the police can issue a fine and may require you to remove the film. It’s a good idea to check local regulations before you buy a film, especially if you’re planning a full‑car wrap or a custom look.
Not all 5% films are equal. Look for a reputable brand that offers a warranty and good heat‑rejection ratings. Ceramic‑based films tend to stay cooler and don’t interfere with phone or GPS signals, while metallic films can be cheaper but may cause signal issues.
Installation matters, too. A professional installer will clean the glass, cut the film precisely, and remove air bubbles for a smooth finish. DIY kits are available, but a slight mistake can lead to bubbling or peeling, which defeats the purpose of a sleek look.
Maintenance is simple: wash the windows with a non‑abrasive cleaner and a soft cloth. Avoid ammonia‑based cleaners, as they can damage the film. If the film gets scratched, you’ll likely need to replace the whole pane, so handle with care.
Finally, think about why you want the tint. If privacy and a bold style are your main goals, 5% works great on rear windows. If you need brighter front windows for safety, stick to a legal tint level like 30% or 35% for the front side panes.
Bottom line: 5% tint offers a dramatic look, decent heat reduction, and privacy, but it’s only legal on certain windows in the UK. Choose a quality film, have it installed by a pro, and keep it clean to enjoy the benefits without getting a ticket.
