Brown Glass Wool Acoustic Board-Acoustic Partition Insulation

Brown Glass Wool Acoustic Board- Acoustic Partition Insulation

Introduction:

Go beyond basic sound control. Our Brown Glass Wool Board Insulation is a precision-engineered acoustic solution designed for architects, contractors, and developers who require reliable, specification-grade performance. Utilizing a dense matrix of brown glass wool fibers, this board is optimized to absorb sound energy and dampen vibrations within partition walls, floors, and ceilings.

How It Works – The Science of Sound Reduction

Sound travels as waves of pressure. Our insulation combats this transmission through a dual mechanism:

1. Mass & Density: The dense fiber structure increases the overall mass of the wall assembly, making it harder for sound waves, especially low-frequency noise, to vibrate through.

2. Sound Absorption & Damping: The intricate, open web of glass wool fibers acts as a labyrinth, trapping airborne sound waves. As sound enters the material, friction between the air particles and the vast surface area of the fibers converts sound energy into negligible amounts of heat energy, effectively dissipating it.

Key Features

• ✅ Superior Sound Absorption – Effectively reduces mid- to high-frequency airborne noise such as speech, music, and office activity.

• ✅ Impact Noise Reduction – Minimizes structure-borne noise from footsteps, furniture movement, and vibrations.

• ✅ Easy Installation – Fits standard wall cavities, floor joists, and ceiling assemblies; can be cut to fit custom spaces.

• ✅ Fire-Resistant & Non-Toxic – Class A fire rating and low-VOC formulation support safe and healthy indoor environments.

• ✅ Thermal Benefits – Adds supplementary thermal insulation, improving energy efficiency alongside acoustic performance.

• ✅ Moisture-Resistant – Options available with vapor barriers or moisture control facing for humid or wet environments.

• ✅ Durable & Long-Lasting – Maintains acoustic performance over time without settling, sagging, or deteriorating.

Applications

Residential: Interior walls between apartments, condos, townhouses, and single-family homes; home theaters, music rooms, and bedrooms.

Commercial: Office partitions, conference rooms, hotels, hospitals, schools, libraries, and studios.

Public & Institutional: Courtrooms, legislative chambers, performing arts centers, worship spaces, and healthcare facilities.

Multi-Family Buildings: Party walls, floor-ceiling assemblies, elevator shafts, and mechanical room enclosures.

Technical Specifications & Performance Data:
