high-performance noise barrier
Subdue® X is a multi-layered acoustic panel constructed from two outer layers of marine grade Okoume ply, compliant to BS 1088, with inner core comprising a dense, damped viscoelastic layer offering excellent noise transmission loss. Subdue was developed to meet noise reduction requirements in marine, commercial and rail construction.
The viscoelastic core is made from a special polymer, developed to provide excellent damping properties that reduce structural vibration, resulting in lower airborne noise. This unique property makes Subdue X the highest performing composite panel in the product range. The product is suited to high privacy areas such Master State Rooms, boardrooms, VIP lounges and interrogation rooms.
The ‘X’ category of ‘Subdue’ panels includes inner cores with densities ranging from 2000 kg/m³ up to 2400 kg/m³, and can be offered in weights ranging from 6 kg/m² up to 14 kg/m².
Coincidence dip is a common phenomenon in lightweight panels, that adversely impacts the sound transmission loss performance in materials such as timber, plywood, sheet metal, low density rigid foams and hollow core walls. However, Subdue’s unique multi layered composition with its inner core layer, shifts the coincidence dip to frequencies limiting its impact, thereby maintaining the performance of panels.
Pyrotek endorses forest sustainability and the preservation of natural environment. We procure highest quality materials from suppliers who hold FSC Certification (Forest Stewardship Council) and PEFC (Programme for the Endorsement of Forestry Certification) amongst other certification programmes. Subdue ‘Okoume’ ply is tested to AS/NZS 2098.11 and classifies as ‘E-0’ for low Formaldehyde emission.
