GTEK™ Phonic Logo

Excellence in design is achieved with a balance of aesthetics and functional performance.

The GTEK™ Phonic perforated plasterboard range allows architects and designers to create beautiful ceilings and walls that achieve high levels of acoustic performance. The panel perforations together with the acoustic fabric and insulation reduce echo and noise reverberation to create a more comfortable environment for work, leisure and education.

What’s good about GTEK™ Phonic:

  • High sound absorption
  • Reduces sound reverberation (echo)
  • A selection of perforations to cater for design requirements
  • A smooth perforated plaster surface for decoration
  • Cloth backing prevents dust and insect ingress
