SP Acoustic Enclosure Panels

Large SP acoustic enclosure around spinning lathes. The enclosure includes increased height to accommodate a crane.

The SP Acoustic Enclosure System is a versatile range of modular acoustic panels designed to provide effective noise control in many general industrial and commercial environments. Panels are manufactured with an integral flush joint which, combined with the inherent flatness of the panels themselves, gives a high standard of appearance to any acoustic housing or noise control refuge constructed from SP Acoustic Panels.

Typical applications range from noise resistant factory offices, sound refuges and quiet rooms for process control to acoustic enclosures around large printing presses and acoustic housings for ventilation plant.

SP Acoustic Panels consist of a high density acoustic fibre core bonded to a light grey, precoated steel outer skin and a solid or perforated inner skin. The high strength, lamella bonded construction maintains great panel stiffness and flatness over large panel sizes.

The SP System can be used to construct frameless acoustic enclosures with a roof span of max 3000 mm. Larger, or non – standard constructions include an internal steel frame.

The SP system includes acoustic doors, demountable panels and acoustic vents.

For external applications, SP acoustic enclosures are fitted with a profiled steel pitched roof, appropriate gutters and downpipes.

Factory assembled units are supplied complete with lifting lugs and an internal frame, ready to be lowered into position. Alternatively, Acousticabs site teams are available to install large or small acoustic enclosures throughout the UK.

SP Panels are easy to cut on site to accommodate services and other obstructions, making them simple and quick to install. Where required, complete enclosure kits can be supplied in flat pack form for assembly by local contractors or by the end user.
