Acoustic Brick - Terreal Facade


Acoustic BrickAcoustic Brick

Acoustic Brick

The acoustic brick is a small formatted acoustic product, perforated on its front face and filled with rock wool.
Laid traditionally like a brick and not fitted mechanically, it can provide not only acoustic correction but also acoustic insulation in a room.
Available only in red-orange as standard (other colours on request).
Perforation diameter: 14 mm

Its strengths

Its acoustic performance, particularly in educational spaces requiring noise reduction.
Reduces transmission of noise from neighboring rooms. Helps provide acoustical correction for the enclosed space due to closed mortar joints. Its traditional aesthetics.
The compactness of its format for use in small spaces. The possibility of fitting it as cladding to a partition wall or as a free-standing dividing wall.

Fixing system

The acoustic brick is a facing brick, used in the traditional manner, laid using standard mortar (350 kg of CPA cement per cubic metre of dry sand). It can also be laid along a wall as a simple facing or as cladding with acoustic or thermal insulation in between. It can be used by itself creating a dividing wall or as an infi ll in a post and beam structure.


There are four possible ways of using this brick as a facing, all governed by Unified Technical Document 20.1 “Small component masonry structures Partitions and walls”:

- against a concrete or masonry partition, each row of bricks is laid with staggered or running joints on a bed of mortar. The mechanical strength of the partition is provided, in addition to the masonry, by 5 mm diameter stainless steel ties, linking the masonry joint to the support wall at a rate of three to four ties per square meter. For indoor use, a strip of cork is used at the join with the finishing screed.

- as partition cladding, laying is identical to the simple facing, except that insulation is inserted (acoustic or thermal), pre-assembled against the support wall, along which bricks are laid with staggered joints and all attached to the support wall using three or four stainless steel ties per square meter, this time passing through the insulation.

- in a dividing wall situation, bricks may only be laid with staggered joints. Stiffeners are required to provide mechanical strength for the wall over large areas: maximum area of 18 sq. m. between stiffeners for a maximum height of 3.5 m.

- as a free-standing wall, bricks may be laid only in the 30 x 20 x 12 format. The bricks are laid with staggered or running joints between post and beam structural assemblies. It is possible to cast stiffening posts in reinforced concrete in an 80 x 80 mm cell at regular intervals, having previously removed the insulation.
At critical points the acoustic brick may be cut vertically, using a diamond tipped saw, preferably lubricated with water.
