02 · Our approach
Two identical windows can perform completely differently. It all depends on the wall, the glass and the volume of each room, which is why Nera never applies generic solutions.


In our investigative analysis, the specialist visits the site to collect all the information about the space and produce a precise diagnosis.


With the data collected, our specialist processes the information and simulates the performance to deliver your tailored solution.


We detail the benefit our solution brings to your project, always aiming at the room's comfort zone as defined by Brazilian standard ABNT NBR 10.152.
