Your options for the centia Fission, Dune Supreme, and Aruba Dune Evo come down to budget, finish, and appearance. Fission (formerly Armstrong Tatra) is the budget option and is a directional-fissured tile; Dune Supreme is the micro-perforated smooth all-rounder; and Aruba Dune Evo is the top smooth tile for a neat and contemporary finish. All three are mineral fibre tiles and are suitable for standard grids, so the choice is more about appearance and price than functionality. This comparison articulates where each one sits.
Zentia Fission (formerly Tatra) — the budget workhorse
Fission is the classic and economical commercial tile with a traditional directional fissured face is a well-known worm-like grooved design found in many schools and offices in the UK. It offers dependable acoustics, decent light reflectance and great value. For economical performance Fission is the clear choice for large areas. RCT stocks it in 595mm (BP958) and 1195mm (BP952). It is also the direct replacement for any existing Armstrong Tatra ceiling.
Zentia Dune Supreme — the smooth all-rounder
Dune Supreme shifts from the cracked look towards a smooth white surface with fine micro-perforations. RCT offers the BP2271 595mm square edge tiles. Compared to Fission, Dune tiles have all-round mineral fibre performance which Dune tiles are known for which is why they are a best seller in the UK. These tiles are great for general commercial interiors where a cleaner finish is desired, but budget doesn’t allow for the flagship tile.
Zentia Aruba Dune Evo — the flagship finish

Designed considering a contemporary and stylish look, RCT offers the 595mm square edge (BP5460) model. This product is positioned at the top of the everyday range and chosen for aesthetic purposes in places like reception areas, client-facing offices and modern interiors. It works best where the design aims for a refined, seamless ceiling.
Side-by-side comparison
How to decide
To find Tatra to Fission, Dune Supreme to Dune Supreme for matching existing Armstrong ceilings, it helps to know the old product name. If you are specifying new, you have to consider the room in relation to the budget: Fission is suited for back-of-house and large-area work, Dune Supreme is good for general office space, and Aruba Dune Evo is ideal for high-end, design-focused areas. All three are grid compatible. Therefore, you can have a higher-grade tile in visible areas and a lower-grade tile in non-visible areas, as long as they are the same size and edge detail in each exposed grid area. In case an RCT requires a tegular (stepped) edge, RCT also stocks Tegular Dune (BP2273).
A note on matching
Mixing tiles is more of a visual problem than a technical problem since they have the same size and edging options. A smooth Aruba tile will obviously look different than a fissured Fission tile. Each visible section of the ceiling must have only one type of tile. Make sure the edge detail (square or tegular) and grid width are the same before ordering.
