Technology
A window is a system.
- 01
Profile
The PVC structure with internal chambers. Its design influences thermal insulation and the rigidity of the assembly.
- 02
Glass
Laminated, multilaminated or double glazing with an air gap. It is the largest surface area of the window and determines much of its sound insulation.
- 03
Hardware
Hinges, locks and mechanisms that enable opening and press the sash against the frame.
- 04
Gaskets
Perimeter gaskets that seal the contact between sash and frame against air, water, and noise.
- 05
Installation
The seal between the window and the wall. Poor installation can negate the system's performance.

| Number of profile chambers | 4 in the frame | 3 | 3 to 5 in the frame · 2 in the sash |
Results are indicative and depend on the final configuration of profiles, glass, dimensions, hardware, manufacturing, installation, and the project's specific conditions. Final performance must be verified through the applicable technical documentation.
