Absorbent-insulating panels
Absorbent and insulating noise-absorbing screens composed of a concrete panel covered on one or two sides with highly absorbent slabs from a mixture of concrete and wood fibers.
For specific projects, we also make patterns or reliefs according to the expectations of our customers.
HBB 01 and 02
The panels can be slipped between HEA profiles, or clapped in front of the structure.
Maximum length: 5000 mm // Maximum height: 2500 mm // Concrete thickness + slab: 200 to 240 mm.
Composition :
- Reinforced concrete panel thickness 100 mm
- Slabs (corrugated HBB 01, or trapezoidal HBB 02) composed of a mixture of concrete-wood and highly absorbent wood fibers
- Absorbers available in natural finish or tinted in the mass, coloring density of 1 to 5%, colors available: green, yellow, gray, light brown, dark brown, red
