aluminium faced damping barrier for rail and marine industry
Subdue SSAL / DSAL is a multilayered acoustic panel developed by Pyrotek to meet noise reduction requirements in the marine, commercial, and rail industry. The product is available with a single (SSAL) or double (DSAL) sided powdered coated aluminium facing for improved fire resistance.
The unique panel system consists of two lightweight hardwood outer layers which sandwich a damped viscoelastic inner core, bonded with WBP (water boiled proof) adhesive. The aluminium layer is applied to the surface of the hardwood.
The viscoelastic core is made from a special polymer, developed to provide excellent damping properties that reduce structural vibration, resulting in lower airborne noise.
