Ultima+ is a laminated mineral fibre ceiling tile designed for total acoustics performance (NRC plus CAC) and high light reflectance. It has a reinforced, scratch resistant DuraBrite face that is soil resistant, impact resistant and scrubbable, with hardened edges for handling durability and resistance to the growth of mould. It is offered in Board, Tegular and Microlook 90 edge details in 600x600, 600x1200 and 300x1200 mm sizes; special items and other sizes are available on request.
