Mass Loaded Vinyl (MLV) is a thin, flexible sheet made from vinyl mixed with natural mineral salts. The added minerals increase the weight of the material, giving it a high mass without making it thick or rigid. This makes MLV very effective for blocking sound.

Mass Loaded Vinyl (MLV) Learning the basics of sound blocking material
What is Mass Loaded Vinyl? • A flexible sheet of vinyl • Mixed with natural mineral salts • High mass but thin material • Used to block sound and reduce noise
Why Mass Matters for Sound • Sound is energy that moves through vibration • Walls vibrate when sound hits them • More mass = harder for sound to pass through • Less vibration means less noise
How Does MLV Work? • Added to walls, ceilings, or floors • Increases the total mass of the structure • Absorbs and blocks sound energy • Reduces sound transmission to other spaces
Benefits of Using MLV • Very effective sound blocker • Thin and flexible • Easy to install • Works in many applications
