Summary
The INSA PMMA 20 noise barrier is the optimal choice for situations requiring a high level of acoustic insulation without losing visibility of the surroundings.
It is especially suitable for roads, urban areas, or elevated railway sections such as viaducts, where effective noise protection is needed without impacting scenic views. Made from polymethyl methacrylate (PMMA), it allows for the incorporation of coloration and/or decorative ornamental elements, meeting both functional and aesthetic requirements.
Compared to the INSA PMMA 15 model, the PMMA 20 offers superior acoustic insulation, making it the most common choice for projects with higher performance demands.
Like the rest of this range, its function is exclusively insulating, without sound absorption.
Characteristics
- Adapted to the environment.
- Variable molding design depending on the project.
- Variable module lengths.
- It does not have acoustic absorbing characteristics.
- Possibility of incorporating coloring.
- Possibility of incorporating decorative elements.
