Manufacturer Direct Car Sunblock 100x50 cm – Rear Window Heat & UV Protection

You step out of the grocery store after a quick run, keys in hand, only to be met with a wall of scorching air as you open your car door. The dashboard glows like molten lava, the steering wheel burns to the touch, and the air inside feels thick enough to choke on. This isn’t just discomfort—it’s daily summer torture. And while most drivers focus on front windshield sunshades, there's a silent culprit amplifying this heat: the rear window.

Why the Rear Window is the Hidden Heat Amplifier

While sunlight enters through all glass surfaces, the rear window often covers a vast area—especially in SUVs, hatchbacks, and sedans. Unlike side windows, which are smaller and more angled, the rear glass lies flatter and broader, acting like a solar panel. Within just 30 minutes of parking in direct sun, interior temperatures can soar over 40°F (22°C) above the outside air. Studies show that up to 45% of solar heat gain comes from the rear and side windows combined—and the rear, due to its size and exposure, plays an outsized role. Worse still, UV radiation penetrates rear glass at rates comparable to or even higher than side windows, accelerating interior fading and posing risks to skin health.

A Single Sheet That Transforms Your Car’s Climate

Enter the 100x50 cm Manufacturer Direct Car Sunblock—a precisely engineered shield designed to combat this overlooked threat. Its generous dimensions ensure full coverage across the rear windows of most vehicles, from compact cars to larger crossovers, eliminating gaps where heat sneaks in. Crafted with a multi-layer composite structure, including a high-reflectivity metallic coating, it doesn’t just block sunlight—it actively reflects it. Independent tests confirm that surface temperatures behind the sunblock drop by up to 40%, translating into a significantly cooler cabin and faster cooldown once you start driving.

From Factory Floor to Your Trunk—Without the Markup

What sets this sunblock apart isn’t just performance—it’s provenance. By cutting out distributors, retailers, and branding middlemen, we deliver straight from the manufacturing line. This direct model allows us to use higher-grade materials, enforce stricter quality control, and still offer a price that undercuts retail competitors. Every roll undergoes three rounds of accelerated UV exposure testing to ensure longevity, color stability, and reflective efficiency—even after months of sun-drenched use.

No More Fumbling in the Heat: Effortless Installation, Guaranteed

We’ve all been there: trying to wrestle a flimsy shade into place while sweat drips down your forehead, the edges curling, the frame collapsing. Our solution? A dual-mode mounting system combining magnetic edge strips with flexible elastic corner brackets. Whether your vehicle has metal trim or a fully sealed window, the sunblock adheres securely in seconds. The innovative 3-second fold-and-release mechanism means setup and storage take less time than unlocking your doors.

The Silent Guardian: Beyond Just Cooling

This isn’t merely a temperature tool—it’s a protective barrier. Blocking over 99% of harmful UVA and UVB rays, it safeguards passengers, especially children and those with sensitive skin, during long drives or parked waits. The matte-finish outer layer adds a subtle privacy shield, deterring prying eyes without compromising visibility from inside. Most importantly, it dramatically slows the degradation of your dashboard, center console, and upholstery, preventing cracks, discoloration, and sticky surfaces caused by prolonged UV exposure.

Cooler Cars, Greener Planet

Every time you deploy this reusable sunblock, you’re making an eco-conscious choice. Unlike disposable foils or single-use shades, this durable fabric withstands hundreds of uses. By reducing cabin heat, you cut down on air conditioning demands—lowering fuel consumption in gas vehicles and extending battery range in EVs. Less AC usage means fewer emissions. Even our packaging is made from biodegradable materials, aligning with a cleaner, smarter approach to mobility.

Real Stories, Real Relief

In Guangzhou, a driver found that after two hours of outdoor parking, the steering wheel remained touchable—unlike before, when gloves were mandatory. A family in Norway, despite cooler climates, uses it year-round; they discovered that winter sun at high latitudes carries strong UV levels, especially on snow-reflective days. One pet owner shared how her golden retriever now naps peacefully in the back instead of pacing anxiously—the shaded space finally feels safe and cool.

More Than a Car Accessory: Unexpected Uses Uncovered

Owners have repurposed the sunblock in clever ways: as a pop-up shade for kids during camping trips, a temporary insulator for sun-baked home windows, and even a DIY reflector in mobile photography setups. Its lightweight yet robust build makes it a versatile tool beyond the garage.

Your Perfect Fit, All Year Round

The 100x50 cm size fits the majority of standard rear windows—from sedans like the Toyota Camry to SUVs like the Honda CR-V. For larger models, slight trimming is possible without sacrificing functionality. In desert regions, use it religiously during peak sun; in humid coastal zones, it helps reduce moisture buildup by stabilizing interior temps. And don’t pack it away in winter—cold-season UV remains high, and the sunblock also helps prevent frost accumulation on the inside of the glass by minimizing temperature swings.

Stop battling the heat. Start driving in comfort. The Manufacturer Direct Car Sunblock 100x50 cm isn’t just another accessory—it’s your car’s first line of defense against sun, heat, and time.
