Phonic Direct Fix

Phonic Direct Fix is a white painted, textured glasswool acoustic ceiling tile. It eliminates the need for an exposed grid, creating a smooth, monolithic surface. Designed for direct application to gypsum board, timber, or metal battens, it offers a high-end finish with excellent noise reduction properties.

Constructed from compounded, high-density glasswool, Phonic Direct Fix is lightweight, high-performing, and user-friendly. It is ideal for classrooms, offices, medical centers, lobbies, and other commercial interiors.
