Specifying Zentia Ceiling Tiles on Commercial Fit-Out and Refurbishment Contracts

When noting Zentia ceiling tiles in a commercial contract, it refers to selecting the correct tile for each specific space, confirming dimensions, and the edge details in relation to the grid, doing the calculations for the ordered quantities including a waste-binder, and securing stock and price information before the program’s demand for delivery. With Armstrong’s legacy, and having been one of the ceiling brands most frequently seen in the UK, Zentia offers specifiers a range that consistently meets the standard, and that is exactly what a fit-out or refurbishment program requires. This guide will provide instructions on how to specify and order in an organized manner. 

Match the tile to each space 

It is rare for a commercial undertaking to employ one uniform type of tile. From the range RCT stocks, specify by application: 

  • General offices and circulationFission for budget-oriented zones, Zentia Dune Supreme for a more refined standard finish; 
  • Client-facing and design-led spacesUltima for a crisp premium appearance, and where stronger acoustics and fire performance are desired. 
  • Tegular (stepped-edge) ceilings — Zentia Tegular Dune (BP2273). 
  • Refurbishment matching existing Armstrong ceilingsThe current Zentia equivalent of the original tile (e.g. Tatra → Fission). 

Please confirm the dimensions, edge, and grid before proceeding. 

In a refurbishment, the new tiles must conform to the current grid. Please confirm thetile size(595mm x 595mm or 1195mm x 595mm sizes, or imperial for older ceilings), theedge detail (square or tegular), and the grid width(24mm or 15mm). During new fit-outs when grids and tiles are being installed together, note them as a matched system to prevent any issues with compatibility. For fire resistance, note the tested tile and grid build-up, for example, Zentia Ultima achieves its fire rating as part of a defined system. 

Calculate quantities properly 

Calculate the area of each ceiling in square metres, divide by the tile coverage (approximately 0.354m² for a 595mm tile), and add a5–10% waste allowanceRegarding perimeter cuts and breakages, these apply more so to intricate designs. The quantity per box also differs by product — Fission 595mm has 16 per box, while the 1195mm has 10 — so check the box counts on each product page. Schedule quantities per room so the order reflects the program, and include extras for ongoing maintenance after handover. 

Secure stock and lock in pricing 

With live contracts, timing is essential; a tile that is unavailable can hold up an entire ceiling division. Zentia is one of the best stocked manufacturers in the UK and RCT can retain large quantities for rapid, often next-day, turns for commonly used items. For contract quantities: 

  • Request a bulk quote– to site if storage is limited, agreed against your programme. 
  • Confirm stockRCT will beat any genuine lower price, which is relevant on competitively tendered work. 
  • Use the price guaranteeFor contract quantities:
    – pricing is fixed against the programme.
    – for the complete amount before confirming a delivery date.
     
  • Stage deliveriesFor contract quantities:
    — to site if storage is limited, agreed against your programme.
     

Plan for the handover and beyond 

An adequately defined ceiling entails extras. From a defined ceiling, the customer will get a minor supply of corresponding tiles for each section, which averts damage to the finish, and saves the hassle of what is coined ‘matching’ when a product is renametd — for example, Armstrong tiles turned into Zentia. It is a minor line on the order that saves a great deal of hassle in the future. 

Frequently Asked Questions 

For a typical office fit-out, what would you suggest for Zentia tiles? 

Zentia Dune Supreme is a great choice for most office spaces as it strikes a good balance between clean looks and overall performance. For large open spaces on a tight budget, Fission is a good option, and for areas that face clients, Dune Evo or Ultima Aruba are better choices. 

What steps should I take to provide the specifications for Zentia tiles for a refurbishment? 

According to the retained grid, please specify the tile size, edge detail, and grid line width; then, provide the current Zentia version for the tile in question. For Armstrong ceilings, please relate the old product name to its Zentia successor. 

Can RCT supply contract quantities quickly? 

Yes, Zentia is among the most stocked brands in the UK, and RCT has large stocks for rapid (often next-day) shipments on standard items. To secure inventory and price caps based on your schedule, please place a request for a bulk quote. 

Should I order spares for the client? 

Yes, keeping a small supply of matching tiles for each area protects the finished ceiling and avoids future issues with matching due to product renaming.
