Hollow-Wall Insert Perforated Grille Panels are custom-designed for shallow cavity applications in residential buildings. They combine a perforated metal face with an acoustic liner and flush-mount frame to reduce mechanical noise transmission, maintain required airflow, and integrate seamlessly with wall finishes.

Product Description

These panels feature 1.0 mm cold-rolled steel with a powder-coat finish matching wall colour. 2.5 mm perforations at 8 mm pitch (~25% open area) maintain airflow while reducing noise. A 15 mm acoustic felt liner is mounted behind the panel. Concealed clip-on mounting ensures only a flush face is visible. Ideal for shallow hollow-wall inserts, residential apartments, and high-end office interiors, providing a balance of aesthetics, airflow performance, and acoustic isolation.
