Acoustical Doors.
Engineered for Performance.

Memtech delivers premium soundproof door systems that block noise, protect speech privacy, and meet the most demanding acoustic and compliance requirements.

The Weakest Link in Soundproofing

Not even the most advanced wall systems can deliver true sound control if the door lets sound escape. Doors often become acoustic weak points (leaky, underperforming, and overlooked) eroding your hard-earned STC performance and speech privacy.

We supply custom engineered acoustical doors, crafted and tested to preserve your system’s acoustic integrity. These high-performance systems seal the gap where it matters, ensuring your assemblies perform as engineered.
They provide:
  • STC ratings from 35 to 55+ to match the performance of adjacent wall assemblies (lab-tested to ASTM E90 sound transmission standards).
  • Complete systems including door leaf, frame, seals, and thresholds for airtight performance.
  • Architectural finish options to complement interior design without compromising performance.
  • Single and double door configurations to suit conference rooms, mechanical spaces, and secure facilities.
We can help your door(s) become a seamless extension of your noise control system.

Acoustical Door Types

Acoustical DOORS

Metal Swinging Doors

Our metal acoustical doors are the workhorses of sound isolation. Rugged, high-performing, and built for spaces where durability and acoustic integrity cannot be compromised.
  • Typically STC 43–57, depending on thickness and seal configuration.
  • Heavy-gauge steel with internal acoustic cores engineered to block airborne sound transmission while keeping overall weight manageable.
  • Available in single-swing or paired double-leaf designs; personnel-size doors up to 4′ × 10′ and oversized doors for large-scale openings such as stage access or industrial test cells.
  • Precision compression seals, drop bottoms, and acoustically rated frames that eliminate flanking paths.
Applications:
  • Theaters, concert halls, and performance venues where both audience comfort and acoustic fidelity matter.
  • Factories and mechanical rooms where equipment noise must be contained.
  • Recording studios, conference rooms, and control spaces requiring absolute speech privacy.
  • Oversized versions for large machinery access, convention centers, or staging areas.
Acoustical DOORS

Wood Swinging Doors

Where design meets performance, our acoustical wood doors provide premium aesthetics without sacrificing acoustic isolation.
  • Typically STC 41–50, making them an excellent choice for interior environments where appearance is equally important.
  • Solid-core engineered wood leaf paired with acoustical steel frames for a complete system that ensures airtight performance.
  • Single swing up to 4′ × 8′ or paired leaf up to 8′ × 8′. Veneer, laminate, and painted finishes available to complement architectural interiors.
  • Integrated gasketing, concealed seals, and precision machining to ensure doors align seamlessly while remaining easy to operate.
Applications:
  • Conference rooms and executive offices requiring speech privacy.
  • Educational spaces such as classrooms or lecture halls where noise transfer undermines learning.
  • Studios and rehearsal spaces where controlled acoustics are critical.
  • Cultural venues (museums, galleries, performance halls) where both form and function matter.
Acoustical DOORS

Bi-Parting and Accordion Acoustical Doors

For spaces that demand flexibility, such as large openings that need to close securely for acoustic isolation, bi-parting and accordion-style acoustical doors deliver.
  • Typically STC mid-40s to mid-50s, depending on configuration and sealing system.
  • Multi-panel systems with acoustical cores, precision hinges, and continuous magnetic compression seals to ensure uniform closure.
  • Panels fold or slide to one or both sides for quick reconfiguration of space; oversized options available for industrial and performance settings.
Applications:
  • Convention centers and multipurpose rooms where partitions must provide both flexibility and acoustic control.
  • Studios, rehearsal rooms, and auditoriums requiring occasional large openings without compromising privacy.
  • Government secure areas and SCIFs where both access and classified speech privacy are mandatory.
  • Industrial test facilities requiring large-scale access combined with noise containment.
Acoustical DOORS

Specialty Industrial Doors

For mission-critical environments where standard assemblies aren’t enough, Memtech engineers custom industrial door systems built to meet the highest acoustic and structural demands.
  • Custom-rated, typically STC 50+, depending on mass, construction, and seal design.
  • Heavy-duty acoustic cores reinforced for durability under demanding operational loads. Options for blast resistance, oversized widths/heights, and continuous use cycles.
  • Multi-layer gasketing, high-mass cores, and resilient seals designed to withstand vibration, airflow pressure, and heavy traffic.
Applications:
  • Test cells for engines, turbines, and machinery.
  • Power generation facilities where high SPL (sound pressure levels) must be controlled.
  • Industrial plants requiring worker protection from hazardous noise exposure.
  • Anechoic chambers and acoustic labs requiring precise and repeatable noise isolation.

Performance Specifications

Every acoustical door system we provide is engineered, tested, and rated to deliver reliable sound isolation.

STC Ratings

Doors are tested in accordance with ASTM E90 for sound transmission loss, with options ranging from STC 41 for standard interior wood systems to STC 57+ for heavy-duty metal and specialty assemblies.

Complete Door Assemblies

Performance depends on the system, not just the leaf. All doors are supplied with acoustically rated frames, perimeter seals, and drop bottoms or thresholds to ensure airtight closure and consistent results.

Construction Integrity

Available in steel, wood, or composite cores designed for high-mass, low-resonance performance while maintaining durability and ease of operation.

Size & Configuration Flexibility

Standard personnel sizes up to 4′ × 10′ single and 8′ × 10′ pairs; oversized and custom-engineered assemblies available for industrial, stage, and large-access openings.

Fire & Safety Compliance

Acoustical doors can be specified with fire ratings up to Class A while maintaining acoustic performance, meeting both safety and code requirements.

Sealing Systems

Precision magnetic compression seals, automatic drop bottoms, and multi-point gasketing provide uniform contact to block sound leaks and flanking paths.

Environmental & Durability Standards

Built for long-term performance under heavy use, with options for low-VOC finishes and systems that integrate into sustainable building designs.

Common Applications

Acoustical doors are essential wherever privacy, compliance, and noise isolation matter.
  • Healthcare Facilities
    Protect patient confidentiality and comply with HIPAA speech privacy standards in exam rooms, consultation offices, and nurse stations.
  • Corporate & Education
    Ensure speech privacy for conference rooms, classrooms, lecture halls, and executive offices, minimizing disruptive noise transfer between adjacent spaces.
  • Government & Security
    Support classified discussions, SCIFs (Sensitive Compartmented Information Facilities), and command centers with doors that meet both acoustic and security requirements.
  • Industrial & Manufacturing
    Reduce hazardous noise exposure in test cells, power generation facilities, and mechanical rooms, ensuring safer work environments and OSHA compliance.
  • Performing Arts & Media
    Deliver acoustic integrity in recording studios, broadcast rooms, theaters, and performance halls, where even slight sound leaks can compromise quality.
  • Hospitality & Public Venues
    Enhance guest comfort and event quality by isolating conference centers, hotels, and convention halls from external or adjacent noise sources.
