(see graph. 1) .Phonbric® and Boreal® use the same type of fixing systems (identical metal 4/6 rail). This enables them to be combined harmoniously. This allows a reinforcement of the shock resistance in case of constructions in exposed areas. In renovation, Phonbric® enables antinoise walls or noisy areas to be brought into conformity with the current regulations. Phonbric® is characterized by its excellent sound absorption between 250 and 4000 Hz. This makes it extremely useful in a large number of applications.
APPLICATIONS (see Acoustic Regulation pages 122 and 123). Absorbent acoustic covering product designed forthe construction of extend anti-noise screens and acoustic correction in interior environments (theatres, classrooms, swimming pools furniture, etc.).

In new construction as in renovation, the Phonbric® system is fixed directly to a wall (concrete or masonry), or on a secondary frame permitting the adjustment of the verticality (application on wall form wall or retaining walls (see diagram 3) .Phonbric® is secured with 2 points of Sikaflex Pro 11 FC type mastic (contact applied between the upper portion of the 4/6 rail and the lower lip of the tile); this gives an anti-vibration effect against the effects of the wind, and maintains the lower parts of the tiles manufacturer in case of an accident. In this way, the tiles cannot be removed by vandalism. However, the easiness of replacing broken tiles should be noted: replacement of a tile anywhere on the façade without deterioration of the structure. Phonbric® can be installed with aligned vertical joints or staggered vertical joints.
