Acoustic Steel Doorset
The AC15, part of DoorTechnik's range of acoustic doors, is a high performance steel doorset designed to reduce the passage of air transmitted sound. As part of a suitable acoustic enclosure or wall, the AC15 may be used to insulate noisy environments from quiet environments.
Developed from our G15 doorsets, the AC15 has been tested to BS EN ISO 140-3 : 1995 and is available with weighted sound reduction values (Rw) of 33 - 41dB depending on specification. The AC15 may be fire rated up to 2 hours, and as such, is part of our range of fire doors.
If you have particular requirements for noise control, which may involve specific frequencies or exceptionally high noise levels, please contact us. As the AC15 is custom built for each application, we can make doorsets especially for your project.
Facts about acoustic doors
- The Weighted Sound Reduction Value (Rw) provides a single number derived from a laboratory test of building elements at multiple sound frequencies.
- The higher the Rw value, the better the sound insulation.
- The Rw value uses a log scale, so that increasing the value by 5 or 6 would actually double the sound insulation.
- For AC15 doors of the same size, doors with a higher Rw value are heavier than those with a lower value.
- AC15 doors have good seals; we have to make them as air-tight as possible.
- Multiple locking points aid air-tightness, particularly on large doors, and hence increase the sound insulation.
The AC15 has many noise control applications, including:
- Recording studios
- Industrial processes
- Interview rooms

The threshold is designed as an integral part of the AC15 acoustic doorset; either carrying acoustic seals itself or by offering a good surface to seal to, whilst providing a stable surface for lower locking points and aiding in weatherproofing. The threshold must be chosen with care to achieve the best balance between good acoustic performance and ease of access.
The best acoustic performance is provided by our two rebated thresholds, the Reverse Head and the Type YTL, which allow the threshold seals to meet the main frame seals with no gaps, giving true four-sided sealing.
Where a low threshold or no threshold is required for ease of access, automatic drop seals will be fitted to the bottom of the door. Drop seals may be either surface mounted or concealed within the door bottom.
Colours and Materials
Steel doors and frames are produced fully finished in leather grain plastisol or may be powder coated to any BS or RAL colour. Please be aware that some powders may be classed as special orders and therefore incur extra charges - please call us with your colour requirement and we will advise.
BS 4800 Colours
Colours shown on your screen or printer may vary from actual product colours, which may also vary slightly between batches. If you would like to see an actual colour sample, please call us.
The U Values for the AC15 steel door have been calculated to EN 673, EN ISO 10077-1 and EN ISO 10077-2. As standard, all AC15 doorsets have an insulated core.
A standard 45mm AC15 with Rockwool core is 2.0 W/(m²K)
The rest of the range is between 1.8 W/(m²K) and 2.2 W/(m²K). Please contact us for more details.
