Acoustic Doors

It has long been understood that excessive noise can affect employee’ health and hearing and so damage their well-being and productivity. As the effects have been increasingly recognised and understood, the demand for efficient protection has risen.

IMS creates single and double acoustic doors with a choice of three levels of sound reduction –30dB, 38dB and 45dB – to provide a high degree of noise control.

Construction

30dB Acoustic Doors
These consist of:
• 1.6mm zintec steel forming a double-skin construction
• a 100 x 65 x 6mm mild steel angle frame for support
• High quality, maintenance-free hinges
• a lockable slam fastener
• Luminous panic bolt
• a single Schlegel-type door seal for compression when closed.

38dB Acoustic Doors
These are manufactured to the same exacting standards as the 30dB door with the addition of greater sound reduction as a result of:
• an increased skin thickness of 2.0mm
• an air gap fitted with 45kg s/m³ mineral wool

45dB Acoustic Doors
These are manufactured to the same exacting standards as the 30dB door with the addition of greater sound reduction as a result of:
• an increased skin thickness of 3.0mm
• an air gap fitted with 96kg s/m³ density mineral wool

The doors also feature:

a lockable two-pointer fastener
a double Schlegel-type door seal to ensure maximum compression when closed.

Double Doors

All three types of acoustic door are available in a double-leaf configuration with a removable centre pillar

Finish

All the doors and frames are finished in zinc primer unless otherwise specified.

Optional Extras

Paint finish
• Double-glazed windows
• Positive door stops
• Recessed sills
• Fixing lugs for building into brickwork
• Sliding doors

Handing

The hand of the door is determined by the position of the hinge when opened towards the operator (i.e. hinges on the left would indicate a left hand door).
