The Phono Spray I-905 and Pouring 7136 systems are thermal-acoustic polyurethane systems made up of two components: polyol and isocyanate. Both systems are applied by injecting grouting “in situ”, obtaining rigid low-density closed-cell foams with strong thermal and acoustic absorption properties in the case of Phono Spray I-905, and rigid closed-cell foams with strong thermal properties in the case of Pouring 7136. These systems are applied as part of a specific construction solution that improves the overall acoustic insulation of said solution. These systems do not feature foaming agents that are harmful to the O-zone layer.
These systems are applied by means spray or grouting using high-pressure equipment, with heating functions, with a mix ratio of 1:1 in volume. I-905 is mainly used to improve thermal-acoustic insulation against airborne noise in the enclosure of renovated buildings, both in partitions between neighbours and external façades.
- Complete suppression of thermal bridges. The insulation has no joints or gaps. It is a continuous form of insulation.
- Strong surface adhesion. No need to use adhesives or glues to install the product.
- It can be moved to a construction site quickly, with no need for transporting or storing bulky products.
- Seals gaps, muffling the passage of sound.
