Premium Acoustic Steel Doorsets for Advanced Noise Control
Controlling noise transmission is critical across multiple sectors. Whether you are managing a cinema, nightclub, theatre, factory, workshop, or generator room, effective noise control is now almost mandatory. For high-performance environments like recording studios, media centres, or science laboratories, specialist soundproofing is essential.
An acoustic steel doorset is specifically designed to reduce sound transmission, measured by the decibel (dB) levels prevented from passing through the closed door.
Versatile Internal and External Applications
Our acoustic doors are suitable for both the external fabric of a building and internal room division. Because aesthetics are often just as important as performance, we supply doors with premium finishing options, including woodgrain and modern surface textures to seamlessly match your building's décor.
Beyond noise reduction, these highly engineered doorsets can be manufactured to offer certified security specifications, thermal insulation, and integrated vision panels. We supply acoustic steel doorsets with ratings up to 57 dB and in bespoke sizes up to 3000mm x 3000mm, complete with multiple additional performance characteristics.
Acoustic Door Decibel (dB) Ratings Explained
The examples below illustrate the real-world effects of our high-performance acoustic doorsets based on their specific Rw (Weighted Sound Reduction Index) decibel rating:
- 35 dB (Rw): Loud speech is audible, but difficult to distinguish.
- 38 dB (Rw): Loud speech is faintly audible, but difficult to distinguish.
- 42 dB (Rw): Loud speech is faintly audible, but cannot be distinguished.
- 47 dB (Rw): Shouting is audible, but cannot be distinguished.
- 52 dB (Rw): Shouting is barely audible.
Industry-Leading Performance Standards
Higher specification acoustic steel doorsets offer incredible performance in both single and double-leaf configurations. Premium doorsets are rigorously tested to meet the following industry standards:
- Acoustic Performance: BS EN 20140 (evaluated in accordance with BS EN ISO 717 Part 1), achieving from Rw 37dB to Rw 57dB.
- Fire Resistance: EN 1634-1, achieving up to 120 minutes of fire integrity and 60 minutes of fire insulation.
- Security Ratings: European Security Standard EN 1627 (RC2, RC3 & RC4) and LPS 1175 (SR1, SR2 & SR3).
- Static and Dynamic Loading: European Standards EN 1628 & 1629.
- Thermal Insulation: ISO 12567-1, achieving a U-value of 1.1 W/m²K.
- Air Permeability: EN 12207, achieving Class 2/4* (single leaf) and Class 1/3* (double leaf). *Single point/Multi-point locking.
- Water Tightness: EN 12208, achieving Class 7A (single leaf) and Class 6A (double leaf).
- Wind Resistance: EN 12210, achieving Class 3/5 (single leaf) and Class 1/3 (double leaf).
- Durability: 62mm insulated doorsets fitted with heavy-duty ‘KO’ hinges tested to EN 1191 for repeated opening and closing to C5 level (200,000 cycles).
Frequently Asked Questions (FAQs)
What are the acoustic ratings on steel doorsets?
The acoustic performance ratings indicate how well the entire doorset contains sound on one side when fully closed. The higher the decibel (dB) rating, the more noise is prevented from travelling through the door.
How many decibels can be heard through an acoustic door?
Most commercial acoustic steel doors specified in the UK sit within the 32dB to 45dB rating range. While speech reduction is a common benchmark, these doors are frequently used to block heavy machinery and mechanical noises. The list below highlights the effects of various Rw dB ratings:
- 20 dB (Rw): Normal speech is easily overheard.
- 25 dB (Rw): Loud speech is clearly overheard.
- 30 dB (Rw): Loud speech is clearly audible under normal circumstances.
- 33 dB (Rw): Some loud speech bursts are understood, but normal speech is inaudible.
- 35 dB (Rw): Loud speech is audible, but not understandable.
- 45 dB (Rw): Loud speech is heard faintly.
- 50 dB (Rw): Shouting will be barely audible.
- 55 dB (Rw): Shouting will not be audible.
