Things No One Ever Told You (About Insulation)

The insulation you're currently using... might not be soundproofing at all 👀

And no one ever told you this.

📌 Fact 1

"Thermal Insulation ≠ Sound Insulation"

What many people don't know is that these two types of insulation work completely differently.

Thermal insulation → Blocks heat energy

Sound insulation → Blocks sound waves

If you buy thermal insulation for a room, sound will still pass through as before, because it wasn't designed for this.

📌 Fact 2

"Insulation can collapse — and that's why your room still has sound"

Typical insulation will collapse over time due to gravity, especially when installed in vertical walls.

When it collapses → Gaps form between the insulation and the wall → Sound leaks through those gaps → The once quiet room becomes noisy again.

You don't even realize the insulation has collapsed because it's inside the wall.

📌 Fact 3

"It's the Airflow Resistance value that determines how much sound insulation provides."

Most people only look at the thickness of the insulation, but the truth is that the more important number is the Airflow Resistance value.

This value indicates how densely packed the insulation fibers are to resist the passage of sound waves. The higher the value, the better the sound insulation.

Some insulation is very thick but has a low value — it provides worse sound insulation than thinner insulation.

📌 Fact 4

"Good insulation must be fully filled — with no gaps at all."

The most common incorrect installation of insulation is not filling the entire cavity, thinking that filling only the middle is enough.

But the truth is, sound will always find gaps, just like water finds its way out. If there's even a tiny gap, sound can pass through.

Good insulation must be tightly packed, filling all cavities, including those in the frame.

🎯 So what insulation can solve all these problems?

If you've read this far and are thinking "How do I choose reliable sound insulation?"

Trandar dBphon — Sound insulation designed to solve all the problems mentioned.

✅ Made from Inorganic Wool with a higher Airflow Resistance than typical fibers, providing measurable sound insulation.

✅ Anti-Slumping technology prevents the insulation from collapsing vertically, ensuring long-lasting performance without degradation.

✅ 100% Non-Asbestos, safe for occupants and the environment.

✅ Specifically designed for sound insulation, not thermal insulation used as a substitute.
