# [Sprayed polyurethane foam systems for facades and partition walls](https://blog.synthesia.com/en/projected-polyurethane-facades-partition-walls)

The acoustic insulation of facades and partition walls of a building is essential to guarantee the **quality of life** of its occupants. Among a multitude of materials with which we can**[insulate facades](https://blog.synthesia.com/en/how-to-choose-best-insulation-facade)**, sprayed polyurethane foam is presented as an optimal material to insulate buildings against external and internal noise.**![Sprayed polyurethane foam systems for facades and partition walls](https://blog.synthesia.com/hs-fs/hubfs/IM%C3%81GENES%20POSTS/Mayo%202018/poliuretano-proyectado-fachadas-divisorias.jpg?width=640&name=poliuretano-proyectado-fachadas-divisorias.jpg)**

 

## **The problems of traditional insulation systems**

The insulation systems that have traditionally been regarded as the only acoustic solutions on the market have **three key problems** in their application for the construction of vertical elements in new buildings:

- The need for auxiliary elements.
- The settlement of the material itself.
- The lack of continuity.

[**Sprayed polyurethane foam**](https://blog.synthesia.com/en/projected-polyurethane-insulating-material) is a thermoacoustic insulation system that solves this problem as it expands from the first application, generating a **continuous insulation** that covers 100% of the surface of facades or partition walls between buildings during its construction.

## **Phono Spray S-904: acoustic insulation for facades and partition walls**

[Phono Spray S-904](https://blog.synthesia.com/en/projected-polyurethane-facades-phono-spray-s-904) is an open-cell low-density sprayed polyurethane foam system, mainly used for thermoacoustic insulation to airborne noise of different building solutions of facades and partition walls. The characteristics of the product are the following:

- Closed cells: <20%.
- Resistance to air flow: r = 5-6 kPa s/m2.
- Dynamic rigidity: s' = 4.83 MN/m3.
- It is a good thermal insulation system: λ = 0.038 W/mK.
