Sound insulation - SilentDirect MLV

SilentDirect MLV – sound-insulating Mass Loaded Vinyl for effective noise reduction

SilentDirect MLV is a high-performance sound-insulating material based on mass loaded vinyl with an EPDM rubber core. The product is specifically designed to block airborne sound and reduce structure-borne vibrations in walls, ceilings, floors, pipes, technical installations, and vehicles. With its thin profile, high density, and flexible properties, SilentDirect MLV offers a professional solution for anyone looking to create a quieter, safer, and more private environment—without compromising on space or ease of use.

Thin, heavy, and highly effective sound insulation

What makes SilentDirect MLV so effective is its high density of 3.33 kg/m² in a thickness of just 2mm. This allows the material to block a wide range of sound frequencies without occupying space in the structure. It acts as an acoustic barrier that effectively slows sound waves, whether it’s unwanted noise from neighbors in an apartment building or mechanical noise from installations, engines, or fans.

SilentDirect MLV can be used in both new construction and renovation projects. It is ideal behind wall panels, under flooring, in drop ceilings, or between layered boards, and performs equally well in residential and office environments as in technical spaces and industrial settings.

When needed, multiple layers of SilentDirect MLV can be installed for even better sound insulation. By combining several layers, the material’s mass increases—enhancing its ability to block both low and high frequencies. This is especially effective in studios, machine rooms, or other spaces with high acoustic demands.

Flexible, compliant, and easy to install

The material is moldable and easy to adapt to different surfaces. You can cut SilentDirect MLV with a knife to fit around pipes, corners, or irregular surfaces. It is attached using staples, adhesive, screws, or other mechanical fasteners depending on the substrate. For quicker installation, fast-drying construction adhesive is recommended. SilentDirect MLV works just as well on flat surfaces as around ventilation ducts, technical shafts, and narrow passages. It can also be clamped between double board layers for maximum sound insulation in, for example, studios, server rooms, or conference spaces.

Ideal for both building and automotive applications

SilentDirect MLV is often used to soundproof walls, floors, and ceilings in buildings, but it is also highly effective in vehicles, boats, machine rooms, and engine compartments where space is limited and noise levels are high. In cars and other vehicles, MLV is used to block engine noise, road noise, and vibrations—significantly increasing comfort. In technical installations, SilentDirect MLV reduces disturbing machine noise, helping to create safer work environments and meet acoustic standards according to current regulations.

Moisture-resistant and durable construction

Thanks to its EPDM-based composition, SilentDirect MLV is resistant to moisture, chemicals, and microbial growth. The product is not negatively affected by high humidity and is well suited for indoor environments such as basements, technical spaces, and other moisture-prone areas. At the same time, the material requires no maintenance and offers a very long service life when installed correctly. Despite its strength, it is not tear-resistant on its own, so it should be handled carefully during installation.

Environmentally friendly and free from harmful substances

SilentDirect MLV is manufactured without hazardous chemicals, heavy metals, or health-damaging plasticizers. It complies with REACH and RoHS directives and contains no substances that violate EU environmental regulations. The product is partially based on recycled material, making it a more sustainable choice compared to many conventional alternatives. The product emits a light rubber scent upon unpacking, which is normal for EPDM-based materials and dissipates after a few days. MLV is allergy-friendly and can be used in most indoor environments where good acoustics and healthy air quality are important.

Optimize your acoustic environment with SilentDirect MLV

SilentDirect MLV is the perfect choice for those seeking a professional-grade soundproofing solution with high performance in a thin and flexible format. The product works in homes and offices as well as in technical installations, studios, vehicles, and industrial settings. Its long service life, easy installation, and versatile applications make SilentDirect MLV one of the most reliable sound insulation materials on the market.
