Soundproofing Wall Systems and Installation:



Taking a wall build up down to its simplest form is thinking of building a framed wall against the given wall space. Creating a structure that adheres to Part E Building Regulations will depend on requirements and restrictions in place. The below system build up is set for a Masonry wall.


For Masonry Walls:

• The stud framing needs isolating using isolations strips.

• The insulation will consist of an Acoustic Mineral Wool between the joist of the frame.

• An Acoustic Plasterboard is then applied to the clip and channel system ensuring a gap of 2 to 5 mm around the perimeter. Ensure the panels are applied in staggered joints. Seal joints with a high Tack Tape.

• Ensure a tapered edge around the perimeter.

• Seal all gaps with appropriate acoustic sealant.
