Yukings absorptive noise barriers combine a perforated or louvered metal face with a high-density hydrophobic rock-wool acoustic core, converting sound energy to heat rather than reflecting it back. This delivers a flatter broadband insertion loss curve across 125 Hz to 4 kHz, making them the preferred choice for residential areas, railways and mixed-traffic noise control projects.
Absorptive noise barriers convert incident sound energy into heat through viscous friction and thermal exchange in porous mineral-wool fibres. Yukings absorptive panels use a galvanized steel or aluminum perforated/louvered face covering an 80-140 kg/m3 hydrophobic rock-wool core backed by a solid galvanized steel back panel. The result is flat broadband absorption with an alpha-w rating of 0.75 to 0.95 depending on panel depth and face pattern.

Explore Highway Barriers →Perforated faces use a 30-40% perforation pattern of small round or slotted holes and provide clean modern aesthetics while louvered faces use 45-degree angled louvers that prevent direct line-of-sight visibility into the rock-wool core. Both deliver equivalent broadband absorption performance and can be mixed within the same project.
No. Yukings absorptive noise barriers use hydrophobic rock-wool infill with a water-repellent binder system. The core is further protected from direct rain ingress by the perforated or louvered metal face geometry and a back ventilation layer. Hydrophobic rock-wool rapidly dries to restore full absorption performance after rainfall events.
Reflective barriers are strong at mid-high frequencies through mass-law transmission loss but do not dissipate the reflected sound energy - it bounces back to the source side or ground. Absorptive barriers dissipate sound energy over a broader frequency spectrum (125 Hz - 4 kHz) producing a flatter broadband insertion loss. For complex traffic noise near receivers, absorptive barriers typically produce a better perceptual reduction.
Yes. Yukings absorptive noise barriers support 8 / 10 / 12 mm UV-stabilized polycarbonate transparent window modules. Windows are acoustically matched modules that install within the same H-post bays and can be positioned at driver viewing height to avoid line-of-sight blind spots on curved sections of highway.
