In all cases in which strict requirements are set for sound insulation to protect people or the environment, Protec Industrial Doors has developed a couple of sound-insulating sectional doors and had them recently tested at Peutz.

The 5 tested doors respectively achieved a sound reduction of 32, 35, 38 and 45 dB. Type Protec A is the sound-insulating overhead door for various areas of application.

The sound-insulating doors are available as 5 models:

• 32 dB certified by Peutz in accordance with ISO 140-3:1995
• 35 dB certified by Peutz in accordance with ISO 140-3:1995
• 38 dB certified by Peutz in accordance with ISO 140-3:1995
• 45 dB certified by Peutz in accordance with ISO 140-3:1995
• 50 dB certified by Peutz in accordance with ISO 140-3:1995
• specific models up to 56 dB are possible

Protec Industrial Doors has tested the sound-insulating overhead doors as complete door structures and not only the panels. As a result, you are guaranteed that the door also has good sound insulation in its practical application. At the same time, these sound-insulating doors have no limitations with regard to use or area of application. It is possible to use the acoustic doors in outer walls.

Areas of application include: theatres, cultural centres, music halls, casings and the various industries.

It is possible to use the sound-insulating doors of Protec Industrial Doors in areas and/or outer walls for which fire-safety requirements are set, because the sound-insulating doors can be constructed as 60-minute fire-resistant models. These models have also been tested and certified.

The sound-insulating sectional overhead doors are always driven by a 400 V drive unit or an electrohydraulic drive unit. It is also possible to have an electrical drive unit with a battery back-up system, so that the door also closes in the event of a calamity, such as a power cut.

Apart from the certified acoustic overhead doors, we can also modify the doors to meet the desired/required sound levels (dB) and the various Hertz bands in consultation with our engineers and acoustic consultancy firm Peutz. This makes it possible to develop and produce sound-insulating doors, for example, in order to additionally attenuate the high or low tones.

In order to take away your worries and supply you with all types of doors as an overall supplier, Protec Industrial Doors also has hinged acoustic doors and firedoors in its product range.
