DAMTEC® vibra-3D
Hard decoupling mat made from high-quality rubber granules
DAMTEC® vibra 3D is an insulation material made from high-quality recycled rubber offered in several texturing and thickness options. Its upper side is smooth with light granular texturing; its lower side is available with different dimple patterns. DAMTEC® vibra 3D is used in extremely sensitive applications, i.e. under compressive stresses ranging from 0.005 N/mm² to 0.050 N/mm².
