Ceiling Tiles — Acoustic Material Guide

Acoustic ceiling tiles are the most widely specified sound-absorbing product in commercial buildings. Available in mineral wool, fibreglass, and metal lay-in formats, they install in standard T-bar grid systems (600x600mm or 1200x600mm). High-performance tiles achieve NRC 0.85-0.90 and provide the primary absorption surface in most office, education, and healthcare environments.

Installation Notes

Ceiling tiles require a suspended grid system with a plenum depth of at least 200mm for optimal absorption. Mineral wool and fibreglass tiles should not be installed in high-humidity areas without a moisture-resistant face finish.

Typical thickness: 15-25mm
