Metador SoundGuard Acoustic Steel Doorsets
The Metador SoundGuard acoustic steel doorset delivers professional-grade sound insulation for commercial and residential applications where noise control is essential. Engineered to significantly reduce sound transmission between spaces, this versatile doorset provides acoustic performance ratings from Rw35dB up to Rw52dB, making it ideal for music studios, conference rooms, medical facilities, educational buildings, and multi-occupancy developments.
Superior Acoustic Performance
The SoundGuard range offers five distinct acoustic ratings to match your specific noise reduction requirements. Each rating corresponds to measurable reductions in audible sound, ensuring you select the right specification for your environment:
Single Door Leaf Options:
- SoundGuard 35 (Rw35dB) – Loud speech remains audible but becomes difficult to distinguish clearly
- SoundGuard 38 (Rw38dB) – Loud speech becomes faintly audible and difficult to distinguish
- SoundGuard 42 (Rw42dB) – Loud speech is faintly audible but cannot be distinguished
- SoundGuard 47 (Rw47dB) – Shouting is audible but cannot be distinguished
- SoundGuard 52 (Rw52dB) – Shouting becomes barely audible
Double Door Leaf Options:
- SoundGuard 35 (Rw35dB) – Loud speech audible but difficult to distinguish
- SoundGuard 38 (Rw38dB) – Loud speech faintly audible but difficult to distinguish
- SoundGuard 42 (Rw42dB) – Loud speech faintly audible but cannot be distinguished
- SoundGuard 45 (Rw45dB) – Shouting audible but cannot be distinguished
- SoundGuard 47 (Rw47dB) – Shouting barely audible
Customisable Specifications
Beyond acoustic performance, the SoundGuard doorset can be tailored to meet additional building requirements. Customisation options include bespoke sizing to fit existing openings, enhanced security features for high-risk environments, improved thermal ratings for energy efficiency, and fire resistance ratings when regulatory compliance demands it. This flexibility ensures the doorset integrates seamlessly with your project specifications without compromising acoustic integrity.
Extensive Colour Range
Choose from over 200 RAL and BS colour options to complement your interior design scheme or corporate branding. Whether you require a subtle neutral finish or a bold statement colour, the powder-coated steel construction maintains its appearance while delivering exceptional acoustic performance.
Applications
- Recording studios and rehearsal spaces
- Medical consulting rooms and treatment areas
- Educational facilities and examination halls
- Commercial offices and meeting rooms
- Residential apartments and party walls

Technical Excellence
Manufactured to exacting standards, each SoundGuard doorset undergoes rigorous acoustic testing to verify its Rw (weighted sound reduction index) rating. The robust steel construction ensures long-term durability and consistent performance, while precision-engineered seals and gaskets eliminate sound leakage around the door perimeter.
Acoustic steel doorsets have become essential in an increasingly noise-sensitive world. Whether you're specifying a steel door for security, fire protection, or thermal performance, incorporating acoustic rating ensures comprehensive protection in any environment where noise control matters.

Delivery considerations
Due to the robust steel construction and acoustic core materials, these doorsets are substantial in weight. We strongly recommend:
- Mechanical offloading equipment (forklift or similar) at the delivery location.
- A minimum of two people to safely handle and manoeuvre the doorset during delivery and installation.
- Requesting the exact weight specification before delivery to plan lifting equipment and personnel accordingly.
Installation requirements
- Ensure the structural opening is prepared to the correct dimensions before delivery.
- Verify that the surrounding structure can support the weight of the steel doorset.
- Use the integrated threaded adjustors (16+ fixing points) for precise alignment and secure fixing.
- Ensure acoustic seals and gaskets remain intact during installation to maintain the specified sound reduction rating.
- Follow manufacturer's installation guidelines to preserve warranty and performance specifications.
