ACOUSTIC GLAZING SYSTEMS
Soundproof Windows & Glass
Engineered for Noise Control
High-performance acoustic glazing systems designed to reduce sound transmission while maintaining light, visibility, and operational continuity.
High-Performance Acoustical Windows
Soundproof windows, or more accurately referred to as acoustical windows, are engineered glazing assemblies designed to significantly reduce airborne noise transmission while maintaining visibility, daylight, and operational awareness.
Unlike conventional insulated glass units, these systems are purpose-built to address traffic noise, mechanical systems, and environmental sound intrusion. High-performance acoustical window systems typically achieve substantial sound reduction (30 to 50+ decibels depending on configuration) by combining multiple layers of laminated glass, asymmetric thicknesses, engineered airspaces, and airtight framing.
When properly integrated, these systems can deliver STC ratings well above standard commercial glazing, making them suitable for demanding noise control applications.

Types of Soundproof Window Systems
ACOUSTIC GLAZING SYSTEMS
Interior Window Inserts
Interior window inserts are secondary glazing systems installed on the room-side of existing windows. By creating a sealed airspace between the existing window and the insert, these systems significantly improve sound isolation without exterior modification.
Key Characteristics & Applications:
- Installed inside the building, behind existing windows
- No exterior access or façade changes required
- Most effective for offices exposed to traffic or rail noise
- Urban commercial buildings, studios and monitoring spaces
- Ideal for industrial control rooms
ACOUSTIC GLAZING SYSTEMS
Replacement Acoustic Windows
Replacement acoustic windows are full-frame window systems designed to replace existing glazing entirely. These systems integrate multiple layers of laminated glass, engineered airspaces, and acoustically rated frames into a single assembly.
Key Characteristics & Applications:
- Higher performance than standard replacement windows
- Multi-pane, asymmetric glass constructions
- Airtight compression seals and rigid frames
- Suitable for new construction or major renovations
- Ideal for commercial or residential buildings near roadways or airports
ACOUSTIC GLAZING SYSTEMS
Double-Window Systems (Window-to-Window Assemblies)
Double-window systems consist of two independent window frames installed in series, separated by a large airspace. This configuration provides some of the highest achievable sound isolation for transparent assemblies.
Key Characteristics & Applications:
- Two physically separate window systems
- Extremely effective for low-frequency noise
- Often used where maximum attenuation is required
- Ideal for environmental noise mitigation, critical listening environments
- Easily cut and field-fit for custom installations

Performance Ranges & Design Considerations
Depending on configuration, acoustical window systems commonly achieve STC ratings from the high 30s into the 50+ range, perceived noise reduction of 70–95%, significant improvement in low-frequency noise control compared to conventional glazing.
Actual performance depends on glass thickness and lamination strategy, airspace depth, frame rigidity and sealing, and integration with surrounding wall construction.
Memtech evaluates these variables during design to ensure the window system performs as intended once installed, not just on paper.

The Memtech Advantage.
Rather than offering a single “soundproof window,” Memtech designs application-specific glazing systems based on measured noise levels, operational needs, and architectural constraints. We guide selection, detailing, and integration so performance is predictable, measurable, and durable.
Data-Driven Design
Our recommendations are based on measured acoustic data, not generic assumptions.
System Integration Expertise
We ensure lagging assemblies interface seamlessly without restricting access or maintenance.
Long-Term Reliability
Materials selected for durability under temperature, humidity, and vibration stress.
Material Procurement
Direct access to a full range of barrier composites, adhesives, and mounting hardware for simplified purchasing.
Local Turnkey Implementation
Clear installation detailing and on-site guidance to ensure correct overlap, seam sealing, and mechanical fastening.
Performance Verification
Optional field measurement and tuning post-installation.
Technical Highlights
High-performance acoustic glazing systems for residential and commercial applications.
Multi-Layer Acoustic Glazing Systems
Engineered assemblies utilizing multiple panes of glass with varying thicknesses to disrupt resonance and improve broadband sound attenuation.
Laminated Glass with Damping Interlayers
Viscoelastic interlayers reduce vibration and re-radiation of sound, improving performance across low-, mid-, and high-frequency noise.
High-Performance Frame Systems
Rigid, acoustically rated frames designed to limit vibration and support airtight sealing around the glazing perimeter.
Airtight Sealing & Compression Gaskets
Continuous seals prevent flanking paths and air leakage, which are common causes of underperforming acoustic windows.
Interior Insert & Full Replacement Options
Solutions available for both retrofit applications and new construction, without compromising performance objectives.
STC Performance into the 50+ Range
System performance varies by configuration, with engineered solutions capable of achieving high levels of sound transmission loss.
Designed for System Integration
Acoustic windows are engineered to perform as part of a complete noise control envelope, coordinating with walls, doors, and ventilation paths.
Support Beyond the Product

Replacement panels and parts available for future reconfiguration
Frequently Asked Questions (FAQs)
What type of soundproof window is best?
The best system depends on noise source levels, frequency content, and installation constraints. Inserts work well for retrofits, while double-window systems deliver the highest performance.
Do soundproof windows eliminate noise completely?
No. They significantly reduce noise to functional levels. Memtech defines success based on measured outcomes, not absolute silence.
Are soundproof windows custom-built?
Yes. High-performance acoustic glazing is typically engineered per application, not selected off the shelf.
Can these systems handle low-frequency noise?
Yes. Systems with large airspaces and laminated glass are especially effective against traffic, industrial, and mechanical noise.
Can windows be retrofitted?
In many cases, yes — particularly with interior insert or secondary glazing systems.
