Buy high quality sound insulation sheet for noise blocking and sound absorbing panels at low price manufactured by Wedge India to control sound in various spaces, such as offices, recording studios, home theaters, and public spaces.
 
Sound insulation sheets, also known as soundproofing sheets or acoustic barriers, are materials designed to block or reduce the transmission of sound through walls, ceilings, floors, and other structures. Unlike acoustic foam, which absorbs sound within a room, sound insulation sheets are used to prevent noise from passing through barriers, making them essential for effective soundproofing. Here’s a detailed overview of sound insulation sheets:
 
Features of Sound Insulation Sheets
1. Sound Blocking:
• These sheets are highly effective at blocking sound transmission across a wide range of frequencies, from low-frequency bass to high-frequency noise.
• They work by adding mass and density to structures, which reduces the amount of sound that can pass through.
2. Materials:
• Common materials include mass-loaded vinyl (MLV), rubber, foam composites, and fiberglass. MLV is particularly popular due to its flexibility, durability, and effectiveness.
• The sheets can be combined with other materials, like lead or dense foams, for enhanced soundproofing performance.
3. Versatility:
• Sound insulation sheets can be used on walls, ceilings, floors, doors, and even around pipes or HVAC systems to reduce noise transmission.
• They are available in rolls, panels, or custom-cut sheets, allowing them to be tailored to specific applications.
4. Ease of Installation:
• Many sound insulation sheets are easy to install and can be applied using adhesive, screws, or staples. Some products come with self-adhesive backing for quick application.
• They can be layered between drywall, under flooring, or behind paneling, depending on the soundproofing needs.
5. Fire Resistance and Safety:
• Some sound insulation sheets are treated to be fire-resistant and meet various safety standards, making them suitable for use in both residential and commercial applications.
 
Applications:
• Residential: Used in walls, floors, and ceilings to reduce noise between rooms or from external sources like traffic.
• Commercial: Applied in offices, conference rooms, and hotels to create quiet workspaces and enhance privacy.
• Industrial: Used to reduce noise from machinery, HVAC systems, and other equipment.
• Automotive: Sound insulation sheets can also be used in vehicles to reduce road noise and vibrations.
 
Common Types of Sound Insulation Sheets:
1. Mass-Loaded Vinyl (MLV):
• A flexible, dense material that adds significant mass to barriers, making it very effective at blocking sound.
• MLV can be hung on walls, laid under floors, or used in ceilings and is often combined with other soundproofing materials.
2. Acoustic Foam Composites:
• Foam composites with sound-blocking layers (like vinyl or rubber) provide both absorption and blocking capabilities.
• These are ideal for applications where both noise reduction and sound absorption are needed.
3. Fiberglass Insulation:
• Fiberglass sheets or batts are used within walls or ceilings to add density and reduce sound transmission.
• They also provide thermal insulation, making them a dual-purpose solution.
4. Barrier Board:
• Rigid boards made of sound-blocking materials like gypsum, cement, or composite laminates are used for robust soundproofing.
• Often used in walls or floors where high levels of sound insulation are required.
 
Installation Tips
• Sealing Gaps: For optimal performance, ensure all gaps, seams, and edges are well-sealed with acoustic caulk or tape to prevent sound leaks.
• Layering: Sound insulation sheets can be layered for increased effectiveness, especially in areas with high noise levels.
• Combining with Other Materials: Pairing with resilient channels, double drywall, or decoupling techniques can further enhance soundproofing results.
 
Maintenance:
• Sound insulation sheets are generally low-maintenance once installed. Regular checks for gaps or damage can help maintain their effectiveness.
 
Sound insulation sheets are a critical component of any comprehensive soundproofing strategy, providing effective noise reduction for both residential and commercial applications.
 
Comparison of Acoustic Insulation for various types of Acoustic Panels
1. Wedge Composite Panels (Both Sound Absorbing and Blocking Materials)
• NRC: 0.80 to 1.00
• STC: 45 to 65, offering both sound absorption and soundproofing.
2. Foam Panels
• NRC: 0.30 to 0.95, depending on the thickness and shape.
• STC: Usually not rated, as foam panels primarily absorb sound rather than block it.
3. Wooden Acoustic Panels
• NRC: 0.50 to 0.90, depending on design (e.g., slats, perforations).
• STC: 20 to 30 if designed with backing materials that help block sound.
4. Perforated Metal Panels
• NRC: 0.50 to 0.85, depending on perforation pattern and backing material.
• STC: Can range from 25 to 45 if used with appropriate backing materials.
5. Bass Traps
• NRC: Generally above 1.00 for low frequencies (below 200 Hz), designed specifically for absorbing bass.
• STC: Not usually rated; purpose-built for absorption.
6. Fabric-Wrapped Panels
NRC: 0.70 to 1.00
STC: Not typically rated for STC as they are designed more for absorption than blocking.
