Acoustic Correction (Absorption)
Behind perforated cladding or as a bare panel; sample α ≈ 0.40 at 500 Hz for 50 mm ICB.
Recommended: ICB
100% natural cork granules expand with steam and agglomerate with their own resin. ICB delivers thermal, acoustic and anti-vibration performance in a single material — used in roof, wall, floor and cold-room sections.
Application
Behind perforated cladding or as a bare panel; sample α ≈ 0.40 at 500 Hz for 50 mm ICB.
ICB + suspension profile with double plasterboard improves airborne/impact noise; lightweight and vapour-permeable.
Grooved ICB boards act as pipe carrier + thermal/acoustic insulation; finished with reflective board and screed.
ICB with integrated OSB strips for fast mounting and good compressive strength in facade/wall renovation.
Layered solution with two ICB layers, vapour barrier and waterproofing for conditions down to −40 °C.
Sections that reduce thermal bridges and keep a stable interior for the 0–12 °C range.
