An effective soundproof wall does not come from a single material
but from a “system” designed to work together correctly
Trandar Hitech Wall is a soundproof wall system that combines the power of

Trandar Zoundboard
Soundproof panel for walls and ceilings | Truly soundproof, space-saving
Technology Damping Compound embedded in the core (Trandar exclusive)
Reduces wall vibration better than general panels
STC value 33–36 dB with a thickness of only 10–15 mm.
Provides higher performance than a double layer of lightweight brick walls
Thin wall system helps to increase usable space by up to 10.5 cm.
Lightweight, reduces building structural load
Non-flammable, strong, impact-resistant Can be drilled for practical use
Dry Process installation 10 times faster than brick, clean job site, controllable schedule
Trandar dBphon S50
Fireproof, Soundproof, Heatproof Insulation | The main sound absorber of the system
Made from หินบะซอลต์ (Basalt Rock) material, non-flammable
Melting point higher than 1,000°C
Value of High Airflow Resistance
Better sound absorption and transmission reduction than general fibers

Certified by มอก. 863-2532 Suitable for project work and actual use areas
When combined as a system
it becomes Trandar HiTech Wall
Zoundboard → Soundproofing, adds wall mass
dBphon → Absorbs sound energy, fire and heat resistant
Heplar → Controls structure, reduces sound transmission through the frame
The result is a high-level soundproof wall system that is truly quiet, strong, safe, fast to install, and controllable on-site
