BlockSound Duo
BlockSound Duo is a two-layer acoustic sandwich panel that combines two sound-dampening principles. A layer of high-density acoustic foam (120 kg/m³) absorbs sound waves and eliminates echoes, while a dense layer of foamed rubber reflects and dampens airborne and impact noise. Thin yet effective—it significantly reduces noise while maximizing usable space in the room. The self-adhesive backing makes installation on walls and ceilings quick and easy. A solution for comfort-class and premium-class housing.
| Design |
Two-layer |
| Composition (layers) |
High-density acoustic foam (120 kg/m³) + sound-insulating foam rubber (9 mm). Thickness options: 19 mm = 10 mm foam + 9 mm foam rubber; 24 mm = 15 mm foam + 9 mm foam rubber; 29 mm = 20 mm foam + 9 mm foam rubber. |
| Thicknesses / Variants |
19, 24, 29 mm |
| Installation |
Self-adhesive (adhesive layer) |
| Acoustic Performance |
The reduction in airborne and impact noise increases in proportion to the panel thickness (single protocol; reference value: 39 mm — 65 dB Rw, sound absorption coefficient 0.65) |
| Weight |
It increases in proportion to the thickness * |
| Stiffness / elasticity |
Semi-rigid; elastic |
| Functions / Purpose |
Improving room acoustics · Reducing impact noise · Sound insulation |
1000 × 4000 mm
Dual action: 120 kg/m³ foam absorbs sound and echoes, while rubber reflects airborne and impact noise. The slim panel saves space. Self-adhesive installation. Three thicknesses (19/24/29 mm) for different application requirements.
Uses
-
Soundproofing of Rooms
Studios, home theaters, bedrooms, and apartments near noisy neighbors or streets—it reduces airborne noise and eliminates rumbling.
-
Walls and Ceilings
Installation on walls, ceilings, and partitions; the self-adhesive backing and large format speed up installation.
-
Impact Noise Dampening
Reduces impact and structural noise in floor slabs and frame structures in comfort- and premium-class residential buildings.
