HOW TO SOUNDPROOF A WALL LIKE A PRO (DIY Style with Luxury Liner™ MLV & 3.5" UltraTouch Batting)

We're Second Skin Audio. We're helping the world stay cool & quiet, one project at a time.

In this video, we walk you through how to build a professional-grade soundproof wall using proven materials and techniques. Whether you're soundproofing a home studio, office, bedroom, or shared wall, this guide will help you tackle the project with confidence.

We’ll be using a high-performance combination of:
🔹 UltraTouch Cotton Batting – Eco-friendly insulation that absorbs mid and high-frequency sound, reducing echo and improving acoustic clarity.
🔹 Luxury Liner™ Mass Loaded Vinyl (MLV) – A dense, flexible sound barrier designed to block noise transfer through walls.
🔹 5/8" Type X Drywall – Heavier and more fire-resistant than standard drywall, this adds mass to help stop sound transmission.
🔹 Acoustical Sealant – A must-have for sealing all gaps and cracks to prevent sound leaks around outlets, seams, and edges.
This method is perfect for DIYers who want professional-level results without hiring a contractor. We'll explain why each layer matters, show the correct order of installation, and give you tips to avoid common mistakes.
📏 From prep to finish, this is your go-to guide for serious sound isolation.
