About Nera

Engineering applied to silence.

Nera was born from a clear need in the São Paulo market: to solve and contribute with door and window solutions so that the city's residents can have more comfort, quality of life and health, through silence.

Nera's founders understood that the solutions available in the Brazilian market are delivered without a precise analysis of whether you will get full comfort in your rooms. That is why our method is to assess each room in detail, understand the noises that cause discomfort and listen to each client, to know the project's goal and specify clearly how much our solution will contribute to reaching it.

The name comes from the precious black stone: dense, discreet, definitive. That is how Nera understands luxury.

Diagnosis, simulation and specification in every project.

01 · A real case

Marginal Pinheiros, 11pm.

In the night measurement of an apartment facing the Marginal highway, the sound level meter read 77 dB at the façade, the equivalent of a blender running inside the bedroom. After the Nera project, the same bedroom measured 41 dB. Below the standard's comfort zone.

02 · Philosophy

“A truly sophisticated home is, above all, silent.”

Sophistication and comfort go far beyond furniture and interior solutions: first of all, the connection between inside and outside must be well established. That is why Nera treats acoustics as well-being infrastructure, measured, simulated and proven, room by room.
