Acoustic Walls


Acoustic Walls


ABSOL acoustic walls are used in high acoustic demanding applications. High acoustic insulation is obtained by wrapping the cinema hall/auditorium/building/studios etc with an individual wall liner comprising of multiple (upto 3) layers of gypsum boards screw fixed on the open side of the counterbalanced Z-Z stud structure fixed between the acoustic head bracket at the top and to the base angles at the bottom. Adjacent cinema halls/auditorium/building/studios etc with common wall, shall be considers as two back to back liner walls without any connection between them. Filling the stud cavity of each liner wall, will enhance acoustical insulation as will do the sealing of the perimeters with Fire and Acoustic sealant that is at the same time providing the necessary air-tightness in case of fire.
Advantages
•Light weight (in comparison to concrete / block-work)
•No need for structural reinforcements nor bracings
•Dry & high-speed installation
•“Easily understood” junctions with different structures
•Not only provides high acoustic performance also provides high resistance to fire
Performance
•Fire protection – up to 2 hrs
•Sound Insulation – up to 75 dB( with sound stop ceiling / bulkhead)
Applications
•Cinemas/ auditorium/building/studios etc Auditoriums (Operas, Concert Halls, Universities)
•Hotels (Halls, Ballrooms, Technical Floors) – up to 10 m

Component:
Gypsum Plaster boardHigh density fire rated plasterboard such as ; FW, MRFW, etc
Acoustic Head bracketUsed as sound isolation device between the roof and the Z-Z studs
Base Angles*Horizontal member of Z-Z metal structure with 50mm minimum flange height.
Z-Z Studs*Vertical member of Z-Z metal structure, consisting of a left and a right Z studs fixed together
FastenersFire rated Anchors are used for fixing the base angles to the floor and the head bracket to the concrete super structure. Appropriated fasteners for other structures.
Hex Head screwsUsed for fixing the Z stud together and for fixing the Z-Z stud assembly to the Base angle; available as self drilling
Drywall screwsUsed for screw fixing the boards to the metal structures; available as self drilling
Joint tape and FillerUsed to get a even smooth and homogenous surface at the joints
SealantApplied at the perimeter areas, to achieve the necessary fire and acoustic performance
InsulationMonoglass/fiberglass Used as cavity infill to enhance sound insulation


ABSOL is a revolutionary technology with an advanced gypsum core and no paper or metal in the center, making it 4 times easier to snap than any other noise reducing drywall brands. ABSOL technology allows simple and straightforward soundproofed-drywall installation. Since then it has changed the building construction industry. With easier faster installation has become the leading sound damped drywall panel installed today.
Benefits :
Faster to install for increased productivity and lower labor costs
Less materials save time,
money and waste
Maximizes usable floor space by using just a single layer Outperforms other noise reduction methods, including soundboard and resilient channel
High reliability: unlike resilient channel, cannot be easily short circuited Abrasion resistant paper • •

Neoprene brackets
In light commercial and residential construction, single-ply gypsum board systems are the most commonly used wall and ceiling systems. Usually such systems meet fire resistance and sound control requirements2. Multi-ply systems , have two or more layers of gypsum board that will typically increase sound isolation and fire resistive performance.Multi-ply systems also provide better surface quality because face layers are often laminated over base layers, so fewer fasteners are needed to attach the face layer. As a result, surface joints of the face layer are reinforced by the continuous base layers of gypsum board. Nail popping and joint ridging problems are less frequent, and imperfectly aligned supports have less effect on the finished
surface.
