Ireland's media production and commercial architecture sectors are experiencing an unprecedented boom. From state-of-the-art recording complexes in Dublin 2 to post-production sound suites in Cork, the requirement for precise decibel attenuation is paramount. Local architectural designs must satisfy rigorous acoustic thresholds defined under the Technical Guidance Document E (Sound) of the Irish Building Regulations.
As standard commercial timber doors fail to meet the required Rw transmission ratings, specialist architects and contractors turn to engineered multilayer soundproof studio wooden doors. The humid maritime climate of Ireland also introduces physical challenges; wooden acoustic doors must be manufactured using high-stability composite timber cores to prevent warping, maintaining tight airtight seal contact points year-round.
Acoustic partitioning between sound-sensitive studio areas requires sound insulation indices of Rw 45dB to 55dB+. Achieving this index is not solely a function of door mass, but requires specialized perimeter seals, automatic drop seals, and decoupled heavy-gauge steel-wood frames. Our manufacturing workflows are tailored to deliver complete assemblies ready to meet these exact Irish statutory compliance standards.
Specially decoupled multi-layered cores combined with acoustic composite panels effectively absorb and reflect structural and airborne frequencies across the critical 125Hz to 4000Hz spectrum.
Complies with global fire ratings (UL and BS EN Standards) from 20 to 90 minutes. Intumescent perimeter seals expand rapidly under heat to block smoke, flame, and flanking noise.
From sleek minimalist aluminum-wood profiles to high-grade walnut, ayous, and poplar veneer finishes. Ideal for modern commercial spaces and high-end residential theaters alike.
Soundproof wooden doors require precise engineering to achieve high Weighted Sound Reduction Index (Rw) values. Our structural architecture relies on dissimilar mass layering. By sandwiching materials of varying densities—such as solid structural timber, acoustic composite membranes, and high-density MDF—we mitigate the coincidence resonance frequencies that normally allow sound to bypass standard timber doors.
For contractors managing large-scale developments in Dublin, Belfast, or Galway, supply chain reliability is a primary concern. Zhejiang Larsom Door Co., Ltd. provides direct manufacturing capabilities with global logistics tracking. We handle complete documentation sets, ensuring that custom fire-rated acoustic doors arrive with corresponding test certifications to satisfy local Building Control authorities.
Our design process incorporates Building Information Modeling (BIM) alignment, allowing architects to insert exact door assemblies, complete with weight, thermal performance, and Rw rating parameters, directly into their digital schematics.

Zhejiang Larsom Door Co., Ltd. is a professional manufacturer specializing in the research, development, production, and global sales of high-quality security doors, armored doors, steel-wood doors, and customized entrance door solutions. Today, the company operates a modern manufacturing facility covering more than 16,000 square meters, supported by an experienced team of over 160 skilled employees. With advanced production management and efficient manufacturing systems, our daily production capacity exceeds 200 sets of premium doors, enabling us to meet both large-scale projects and customized orders with reliable delivery.
To continuously improve product quality and manufacturing efficiency, Larsom Door has invested heavily in advanced automated production equipment, including CNC laser cutting machines, CNC bending machines, automatic welding systems, high-speed turret punching machines, automatic sanding machines, and modern powder coating production lines. These advanced facilities, combined with strict quality control procedures, ensure that every door meets international quality standards.
Quality is the foundation of our business. Larsom Door strictly implements comprehensive quality management throughout every production process, from raw material selection to final inspection. Our products comply with international quality standards and have earned an excellent reputation among customers worldwide. Guided by the philosophy of "Quality First, Customer Foremost, Innovation for the Future," we continue to improve our manufacturing capabilities, expand our international market presence, and build long-term partnerships with customers around the world.
In accordance with Ireland's Climate Action Plan, commercial development projects increasingly request bio-sourced and low-embodied carbon construction materials. We are constantly researching acoustic assemblies made with FSC-certified timber frames and natural binder resin composites. By avoiding toxic formaldehyde resins, our studio doors meet strict indoor air quality requirements (such as LEAD and BREEAM certifications).
Our engineering roadmap also includes the integration of hidden mechanical drop seals that act dynamically when the door is closed, preventing the degradation of acoustic seals while improving general thermal performance (U-Values).
The demand for modern security and smart control units in recording studios has pushed us to innovate. Our modern studio wooden doors can be pre-channeled and pre-milled to support smart electromagnetic locks, biometric access controls, and low-voltage cable paths without causing structural flanking paths that compromise sound reduction ratings.
