A thick wall doesn't mean good soundproofing.

Many people think “The thicker the wall = the better the soundproofing”

But the truth is ❌ not always because soundproofing “doesn’t just depend on thickness”

But it depends on 3 main factors:

1️⃣ Mass (Mass)

Heavy and thick walls “can really reduce sound”

But it's only effective for certain types of sound, such as general speech.

👉 But if it's impact sound / low bass sound thick walls alone “are not enough”

2️⃣ Structure (Structure)

Good walls must have a “layered system”

such as double-layered walls or with an air gap in between

👉 Because sound can “easily vibrate through the same structure”

3️⃣ Internal Materials (Absorption)

This is where people make the most mistakes.

Solid concrete walls, even if thick, but “reflect sound” instead of absorbing it.

👉 This allows sound to still penetrate or accumulate in the room.

This is why  Trandar Acoustics doesn't just design “walls” but creates a “soundproofing wall system Trandar Hitech Wall"

It's a wall system designed holistically, not just by adding thickness.

Consists of:

• Zoundboard panels that help reduce sound transmission
• Double Stud structure that separates vibrations
• dBphon insulation that helps absorb internal sound
• Heplar frame that helps stop sound vibrations
• and Sealant to close every “sound loophole”

👉 This prevents sound from “continuing” from its origin.

Features 

• Soundproofing up to STC77
• Fire resistant for up to 4 hours
• Lighter than general walls, but high performance
• Dry Process installation system, fast installation, clean work site

“Because silence… doesn't come from thickness, but from ‘a system that understands sound’ ”
