For greater Peace.

Why don’t timber and wood concrete composite ceilings insulate impact sound adequately for everyone? It’s simple. They can’t control the basses! Our LIGNATUR silence element efficiently solves the problem of low-frequency sound with tuned mass dampers. No more dull droning and rumbling.

Explanation videos on soundproofing

Good soundproofing in multi-family houses, schools and offices is essential and is the result of good planning. Both airborne sound and impact sound need to be taken into account. Undesired noise can be eliminated by optimising the hollow box elements. LIGNATUR – a step ahead of the sound.

In the films, our consultants explain how it's done with LIGNATUR.

Sound samples silence12

First listen to a music example to hear how silence12 ceilings really dampen sound. Use high-quality speakers or headphones.

Further sound samples demonstrate the sound insulation in comparison to other ceiling systems during impact sound excitation.

Separation floor constructions - silence 12

Rw,P = 72 dB, C100-3150 = -1 dB, C50-3150 = -9 dB
Ln,w,P = 45 dB, CI,100-2500 = -2 dB, CI,50-2500 = 0 dB

Prognosis sound transmission for separation floor constructions

The forecast model for airborne noise insulation in buildings essentially corresponds to DIN EN 12354-1.  We developed the forecast model for impact sound transmission in cooperation with the ift Rosenheim following DIN EN 12354-2.
