Worldwide soundproofing solutions
Sonoblock® Blocktec, Self Adhesive and ALU are high density synthetic soundproofing membranes, that offers good acoustic insulation in different
building elements.
The material is visco elastic and is extremely flexible even in cold temperatures. It doesn't contain any PVC.
In combination with the hybrid foam HD Foam Plus+ and two plasterboard layers a Rw = 75 dB (STC) is obtained.
PROPERTIES
- RW of 28dB using one independent layer (7kg/m²) (test certificate) .
- Best acoustic insulation when combined with lightweight panels or sound absorption materials.
- It doesn't contain lead, but insulates much more better then lead.
- Sonoblock® Blocktec reduces acoustical bridges and critical frequency coincidence (always a big problem in plasterboard
constructions)
- Very good low frequency performance.
- Fire retardant Euroclass B s2 d0. (test certificate)
- Very good elongation/very easy to apply on different surfaces and also very flexible.

This membrane has excellent soundproofing properties. Many construction materials and techniques do not provide enough damping. Plasterboards
absorb little sound energy because they vibrate and re-radiate sound on the other side quite effectively. Sonoblock® Blocktec viscoelastic membrane however has tremendous density and mass
whilst being extremely 'limp', its acoustically better than lead of the same surface mass, so will help absorb sound energy far more efficiently.
Sonoblock® Blocktec Acoustic Membrane provides the best of both worlds, high additional mass and high damping, that can be applied not only over 100% of the area in question but uniformly.
