ChovAIMPACT PLUS is a high-quality membrane composed of three layers that significantly reduce impact noise. The layers are made of polyethylene and produced through direct extrusion of the material through a die to achieve an excellent cross-section. This process involves physical expansion, creating closed, waterproof cells that give the membrane the appropriate consistency and excellent quality. The extrusion processes are carried out using modern, state-of-the-art production facilities through which the company contributes to reducing the greenhouse effect.
The manufacturing process is extremely important because experts from ChovAhave developed an impressive and functional material. ChovAIMPACT PLUS, with its multilayered structure, contributes to high compression resistance, enabling the membrane to effectively reduce impact noise in floating floor systems.
ChovAIMPACT PLUS is a high-quality material featuring excellent acoustic and sound insulation properties, a good thermal conductivity coefficient, and water resistance.
With the acoustic membrane ChovAIMPACT PLUS, you will eliminate noise generated by heels, furniture movement, or renovation activities. This is the most common type of impact noise in residential spaces, transmitted through floors and walls and then through the air to reach you. By choosing this membrane, you will ensure peace and quiet for both yourself and your neighbors.
Impact noise soundproofing membrane for use in residential buildings (apartments, houses), public buildings (schools, malls, hotels, restaurants, ritual halls), office buildings and others.

TriACUSTIC 35 is a multilayer composite product composed of a polyethylene sheet thermally bonded to another high-density, highly elastic sheet. It is a flawless and multifunctional solution for reducing both airborne and impact noise. On one side, the high-elasticity sheet acts as a soundproofing barrier by reflecting sound due to its high density. On the other side, the polyethylene sheet reduces the transmission of impact noise. TriACUSTIC 35 is effective across a wide frequency range, thanks to the density and flexibility of the viscoelastic sheet combined with the high elasticity of the polyethylene sheet. The material is available in two versions with different thicknesses and technical specifications — TriACUSTIC 35 (7 mm) and TriACUSTIC® 65 (14 mm).
TriACUSTIC 35 The sound-insulating absorbing underlay is an excellent solution for reducing both airborne and impact noise transmission. It is used beneath concrete slabs—between homes, garages, or commercial spaces. Airborne noise insulation: 64 dB. Soundproofing Impact noise reduction: 18 dB. It can also be used as a sound insulator for drainpipes and gutters.
Installation is quick and easy, but it is essential to ensure beforehand that the substrate is clean and free of irregularities. The polyethylene membrane should be placed facing the substrate, after which the remaining material is laid to cover the entire surface.
The joints are sealed with ChovASEAL self-adhesive tape, ensuring the material’s waterproofing. The next step involves using ChovAIMPACT STRIP, which must be installed where walls and columns meet to prevent rigid joints with the floor. Finally, a mortar screed is applied to complete the system.
Membrane for soundproofing for impact and airborne noise. It is applied between concrete floor slabs in apartments, houses, garages, or commercial properties.
TriACUSTIC 35 It is recommended when internal partition walls have not yet been constructed, and TriACUSTIC 65, when they have already been constructed.
The material provides excellent sound insulation for drainpipes and gutters, as well as serving as a perfect component in floor soundproofing systems.
