Armstrong Ultima Mineral Fibre Ceiling Tile

RH99 Ultima ceiling tiles combine the impact and scratch-resistant DuraBrite surface with excellent sound absorption from a smooth, non-directional surface.

For Green Star rated projects, Ultima is covered by an independant Environmental Choice Certificate.

RH99 Ultima's HumiGuard Plus has no-sag performance and BioBlock paint inhibits the surface growth of mould and mildew. If you want the best combination of visuals and sound absorption then Armstrong Ultima should be your choice for quality office ceilings.
