Why Aerogel Makes Cleo the Coolest Wi-Fi Router on the Market

If you’re looking for the most advanced, compact Wi-Fi 7 router for your smart home, Cleo is built differently, right down to the materials inside. One of the most innovative (and unexpected) features? A cutting-edge thermal insulator called aerogel.

Yes, aerogel, sometimes referred to as “frozen smoke,” is a synthetic, ultralight material first used in space exploration. Now, it’s helping redefine home Wi-Fi hardware by solving one of the biggest challenges in compact router design: managing heat without sacrificing performance.

The Problem with High-Performance Routers? Heat.

Modern Wi-Fi routers are doing more than ever, handling gigabit speeds, multiple devices, low-latency applications, and smart home automation. That power comes with heat.

Cleo’s wall-plug form factor is sleek and minimal, but it’s packed with Wi-Fi 7 capability. In heavy use, the device’s outer case can reach temperatures of 52°C (125.6°F) enough to fail key thermal specifications and feel hot to the touch.

To keep Cleo compact and powerful, the design required a smarter solution than fans, vents, or large heat sinks.

Aerogel: Space-Age Thermal Technology for Everyday Wi-Fi

Aerogel is one of the world’s best insulators, with lower thermal conductivity than air itself. By applying a thin layer of it inside Cleo’s casing, we created a highly effective barrier that prevents internal heat from transferring to the outer shell.

The results speak for themselves. Internal testing showed a 3–4°C reduction in surface temperature, helping Cleo meet the stringent thermal requirements from top communications service providers (CSPs) like ensuring the temperature difference between the device and ambient air stays under 25°C.

With aerogel, Cleo passes spec while keeping performance fully intact.

Benefits

Aerogel might sound like an obscure engineering choice, but the benefits are immediate. Cleo runs cooler, safer, and smarter, all without bulky fans or vents.

In everyday use, it simply works. Quietly, reliably, and comfortably. The aerogel stays hidden, but its impact is unmistakable.

A First in the Market

Based on available market research, no other home Wi-Fi router currently uses aerogel. Larger models can rely on more conventional thermal solutions, but Cleo’s compact design and commitment to premium performance required an entirely new approach.

The result is the first consumer router to use aerogel to solve a thermal challenge without compromising Wi-Fi speed, signal, or form factor.

Why This Innovation Matters for Connectivity 

Because design matters. And when existing options fall short, new solutions are created.
Cleo’s aerogel insulation might sound like a technical detail, but it’s a small feature with a big impact, solving real problems, enhancing the experience, and enabling smarter, safer technology for the connected home.

Cleo is more than a Wi-Fi router. It’s a smarter way to connect. Cooler, quieter, and built differently from the inside out.
