The sleek, powerful design of our manufacturer-direct sunblock in action — transforming any back seat into a cool, private sanctuary.

When summer turns your parked car into a mobile sauna, it’s not just uncomfortable — it’s costly. Heat soaks into your dashboard, fades upholstery, and raises cabin temperatures to dangerous levels. But what if you could stop up to 90% of that heat before it even enters? Enter the **100x50 cm Car Rear Window Sunblock**, engineered by leading manufacturers to deliver unmatched UV protection, thermal resistance, and everyday convenience — without the retail markup.Unlike generic sunshades that slip, sag, or fail under intense sunlight, this rear window shield was born from real-world data and driver feedback. Designed with precision, it bridges the gap between performance and practicality, offering a seamless defense against solar aggression.

When Your Car Becomes a Mobile Sauna

Imagine returning to your vehicle after a quick grocery run, only to be greeted by a blast of 60°C (140°F) air. That’s not just unpleasant — it’s harmful. Prolonged exposure to direct sunlight accelerates interior aging, causing dashboards to crack, leather seats to fade, and plastics to warp. Beyond material damage, trapped heat increases fuel consumption as your AC works overtime to compensate. And let’s not forget the human cost: studies show that surface temperatures inside a closed car can exceed safe limits within minutes, posing risks especially to children and pets.This isn’t just about comfort. It’s about preserving your investment and protecting your health.

The Science Behind the Size: Why 100x50 cm?

You might wonder — why exactly 100x50 cm? The answer lies in extensive analysis of SUV and sedan rear window dimensions across top global models. From compact hatchbacks to mid-sized crossovers, this size achieves near-universal coverage while allowing flexibility through its innovative stretchable edges. Whether you drive a Honda CR-V, Toyota Camry, or Ford Escape, this sunblock fits snugly without gaps or creases.Its adaptive silicone trim gently conforms to curved glass surfaces, creating a custom-like fit without suction cups or adhesives. No residue. No scratches. Just clean, secure installation every time.

The stretchable edge ensures a perfect seal on both flat and curved rear windows — no tools required.

Beyond Shiny Surfaces: Real Heat Rejection Without Compromise

Many sunshades rely on flimsy silver coatings that degrade over time, losing reflectivity and leaving behind sticky residues. Ours takes a smarter approach. Built with a dual-layer system — high-density polyester fabric bonded to a micro-thin metalized reflective layer — it blocks infrared radiation and reflects solar energy *before* it penetrates the glass.In controlled tests, vehicles equipped with this sunblock recorded internal temperatures up to **25°C (45°F) cooler** than those using standard foil-based alternatives. Even more impressive? It maintains effectiveness after repeated use, folding, and exposure to extreme conditions.

Ease Meets Elegance: Installation in Three Simple Steps

Gone are the days of wrestling with awkward clips or sticky pads. Thanks to a hybrid magnetic-electrostatic attachment system, setup is effortless. The lightweight frame uses static cling to adhere smoothly to the glass, while discreet magnetic strips along the border enhance stability — even on windy highways.Just unfold, position, and press gently. It holds firmly in place yet removes instantly when needed. And when folded? It collapses into a compact circle smaller than your palm, easily slipping into glove compartments or door pockets.

From Factory Floor to Your Backseat — No Middlemen, No Markup

By cutting out distributors and selling directly from the manufacturer, we eliminate unnecessary costs — but never compromise on quality. Each unit undergoes rigorous stress testing for UV resistance, tensile strength, and optical clarity. What you get isn’t a discount product; it’s premium protection at a fair price.Customers in Dubai, Phoenix, and Sydney have shared photos of their units surviving months of desert sun and coastal humidity — still performing like day one. These aren’t isolated cases; they’re proof of intelligent design meeting durable execution.

More Than a Sunshade: A Lifestyle Upgrade

Parents love it as a privacy curtain during long drives — keeping napping toddlers shielded from prying eyes at traffic lights. Travel influencers use it to control lighting for in-car content creation, achieving soft, diffused backlighting ideal for reels and vlogs. Some even repurpose it as an emergency window insulator during winter nights.It’s not just functional. It’s versatile.

Redefining Smart Protection

This isn’t the cheapest option online. It’s the smartest. Because true value isn’t measured by upfront cost, but by lasting performance, thoughtful engineering, and the daily relief it brings.
