Can Phonic Direct Fix be installed without a suspended grid?
Yes. The tile is designed to fix directly to gypsum board, timber battens, or metal battens, removing the need for an exposed grid system entirely.
Does adding an air gap improve acoustic performance?
Yes. At 20 mm with a 35 mm air gap, the NRC rises from 0.75 to 0.85 and the alphaW from 0.55 to 0.85.
What recycled content does the tile contain?
The glasswool body contains 80% pre-consumer recycled content, comprising 30% industrial waste and 70% civilian-used waste from reclamation depots.
