Solutions

Materials & services.

Five window typologies, one rule: none of them is specified without a diagnosis. The right specification depends on your room, not on the catalogue.

Residential comfort

NERA Flow

30dBWindow Rw

Profile Lighter profiles, ideal for small openings.

Nera Flow is the lightest system, so that opening and closing the window feels softer to the touch. It was designed for small openings, delivering performance in line with our specialists' analysis.

01 · The ranges

Three ranges, one logic.

What sets one apart from the other is the profile: lighter for small openings, more robust to span large ones. Choose the line in the window above to see each one's details.

Rw is the window's laboratory performance. What you hear inside the room is a different figure: it depends on the wall, the size of the opening and the volume of the room. That is the one the consultation calculates.

Types

  • Sliding
  • Casement
  • Top-hung
  • Fixed

Add-ons

  • Integrated blind
  • Motorised blind
  • Shutter

Sol, Sombra and Conforto

Every range has solar-control versions. They change the glass for heat, not for noise.

Finishes

There is a wide range of finishes, including powder coating, anodising and wood-effect sublimation, and you can choose while talking to our specialist.

02 · How the window reaches you

Overlay or built-in.

There are two ways to install a Nera window. Which one suits your project is a decision of the diagnosis, it depends on the opening, the works and the result you expect.

The Nera window, with an anthracite frame, is fixed to the wall over the opening, and behind it the old white window shows, with the air gap between the two.Living room with an armchair, throw, open book and coffee.

Overlay

The Nera window is installed over the existing one, without removing it. It's the route for those who want to solve the noise without construction work, and the gain comes precisely from the air cavity formed between the two windows.

  • No demolition on the façade
  • Fast installation, with the home occupied
  • Suited to apartments and retrofits

Built-in

The existing window comes out and the Nera one takes the opening, integrated into the masonry. It's the specification for new builds and renovations, when you want the definitive finish and the best performance the opening allows.

  • Uses the full area of the opening

03 · Room-by-room acoustic study

The catalogue doesn't decide. The study does.

The Nera solution is defined after an on-site diagnostic analysis. The same product cannot be sold with the same promise in every case: it's the specialist's assessment, in your room, that guarantees the promised comfort.
