To specify Knauf AMF for a large commercial fit-out, you need to choose the appropriate tile (Planet, Sand, or Orbit) for each area, confirm the size and edge type with the grid, do a quantity take-off including a waste allowance, and check stock and pricing against the programme. Because of AMF’s competitive pricing, reliable performance, and good availability, it is ideal for contract-sized jobs. This guide explains how to specify and order it cleanly in bulk.
Match the tile to each space
Confirm size, edge and grid
The AMF tiles RCT stock are square edge sizes of 595mm x 595mm and 1195mm x 595mm, compatible with a standard 24mm exposed grid. During refurbishment, align with the existing grid; for new fit-outs, order a 24mm grid that is compatible with the tiles. Check the grid width and edge detail prior to finalizing contract quantities, as discrepancies found after large scale production are costly to adjust.
Confirm fire requirements
AMF mineral fibre tiles have reliable reaction-to-fire performance. However, the fire protection a ceiling offers relies on the entire build-up — tile, grid and soffit above. Where a fit-out has specific fire requirements, check that the tested build-up addresses this and retain the documentation for the building file. A tile rating should never be assumed to meet a system requirement.
Calculate quantities and waste
Calculate the area of each ceiling in square metres, divide by tile coverage (approximately 0.354m² for a 595mm tile), and add a5–10% waste allowanceDepending on the complexity of the layout with regard to the number of columns or bulkheads, different quantities for cuts and breakages may be required. For each box type (Planet, Sand, and Orbit), the box quantities vary (e.g. 20 per box in 595mm, 12 per box in 1195mm). Spares for the client’s future maintenance also need to be included. Along with the programmed quantities, schedule the quantity by room.
Secure stock and pricing
While the contract is active, verify the stock for the entire amount and fix the price based on the contract’s program. RCT secures AMF stock and price guarantees — we will undercut any genuine competitor price — which is relevant for competitively tendered jobs. For tiles and any grids and accessories, ask for a bulk quote so that they are all priced as one, and if storage is an issue, stagger delivery to the site in accordance with the build programme.
Plan for handover
Provide the client a document referring to the AMF tiles specified — product, size and edge — and an area stock of matching spares. Held spares save a reorder deficiency and protect the finish, especially in knock prone commercial areas.
Frequently Asked Questions
Which AMF tile should I choose for a large office fit-out?
For general and client-facing office spaces seeking a refined finish, go for AMF Sand or Orbit. Choose Planet for budget-led/back-of-house areas. The 1195mm size results in fewer joints across larger floor plates.
What grid do AMF tiles need?
The AMF tiles RCT stocks feature square edges and are designed for a standard 24mm exposed grid. In refurbishment projects, these tiles match the retained grid. In new fit-outs, specify a compatible 24mm grid in addition to the tiles.
Do AMF tiles have a fire rating for contract work?
AMF mineral fibre tiles provide reliable reaction-to-fire performance but fire protection is reliant on the entire tile, grid and soffit build up. Verify the tested build-up complies with any specified criteria and retain records for the building file.
Can RCT supply AMF at contract scale?
Yes, RCT holds the AMF stock. RCT can supply the tiles, grids, and accessories and provides a price guarantee. You may request a bulk quote to confirm stock and secure your pricing to your program.
