Zentia Armstrong Cortega Ceiling Tiles (Square Edge) 600mm x 600mm
The industry-standard fissured tile, offering a reliable balance of acoustic performance and value.
Our Zentia Cortega Ceiling Tiles (formerly Armstrong Cortega) are one of the most widely used suspended ceiling panels in the UK. Featuring a classic multi-directional fissured pattern, they provide a clean, professional white finish that suits a vast array of commercial interiors.
We recommend the Cortega for projects where budget and performance must meet in the middle. It delivers Class D sound absorption (0.55 αw) to control noise, combined with strong sound attenuation (34dB) to prevent sound traveling between rooms—making it an excellent choice for privacy.
Additionally, the surface reflects 82% of available light. This high reflectance helps reduce eye strain in offices and classrooms while maximizing the efficiency of your lighting fixtures.
