DAMTEC® wave 3D
Excellent Acoustic insulation dimple textured underlays under floating screed, cement screed and wood subfloors
DAMTEC® wave 3D is the ideal rubber underlay under floating screed /concrete slab or underneath rigid floor elements on wooden subfloors, providing outstanding elasticity and extremely high resistance to compressive loads. There are 2 thickness for your selection: 8/4mm (impact sound improvement: ≤30dB) or 17/8mm (impact sound improvement: ≤39dB) . DAMTEC® wave3D provides a wide range of benefits under screed or rigid floor elements including long service life and superb strength.
