Suspended ceiling systems used for creating sound-absorbing ceilings to control sound reflection in larger spaces.

Description

Suspended ceiling systems used for creating sound-absorbing ceilings to control sound reflection in larger spaces, creating a more comfortable level of sound and improved audibility.

Features and benefits:

  • Variable cavity depth – can be optimized for service and insulation requirements.
  • Up to Class B acoustic absorption.
  • Utilizes GTEC Suspended MF framing.
  • One set of components on site.
  • Easy to install.
  • Creates a ‘false ceiling’.
  • Can be used to upgrade existing structures.
  • Perforated boards in a range of patterns.
  • Provides a range of aesthetic options to add variation in large spaces.

Application:

Suspended ceiling systems used for creating sound-absorbing ceilings to control sound reflection in larger spaces.
