What are the sound insulation ratings of the Trandar Hitech Wall acoustic wall system?

Trandar Hitech Wall

High-Performance Acoustic Wall System with Exceptional STC Ratings

For interior designers and architects seeking superior acoustic performance, noise control, and privacy, "Trandar Hitech Wall" is a high-performance acoustic wall system designed specifically to meet stringent modern architectural requirements. Developed using TSIS (Trandar Sound Insulation System), it combines high-performance sound isolation technology featuring Trandar Zoundboard enhanced with Damping Compound, paired with heavy-duty Trandar Heplar Pro metal studs and Trandar dBphon acoustic insulation. This creates an acoustic wall system that effectively blocks noise across all frequencies.

To help you select the most suitable specification, TSIS offers a wide range of options tailored to various acoustic requirements (STC), providing solutions for every project type from standard offices to high-end executive boardrooms that demand maximum sound isolation.

What is an STC Acoustic Wall Rating?

STC (Sound Transmission Class) is an integer rating of how well a building partition attenuates airborne sound. Higher STC ratings indicate better sound insulation. Trandar TSIS offers solutions ranging from STC 43 up to STC 77 to meet diverse project acoustic requirements.
