Diffusion is a robust, sound-reflecting ceiling panel designed to compliment the Triton range of sound-absorbing ceiling panels.  With the same Sonatex finish, Diffusion can be mixed and matched with Triton absorber panels to enhance speech clarity, intelligibility and the tonal qualities of played music.

Ideal for use in music rooms as well as traditional didactic style teaching spaces, lecture theatres and some classroom settings where it is desirable for the teacher's voice to be projected to the back of the room.


Manufactured from fire-resistant Sonatex 250 kg/m³ composite facer panel laminated to an 750 kg/m³ 10mm-thick plasterboard backer panel.  Made in NZ.

  • Made in NZ, meaning short lead times.
