The core difference between Burgess CEP and Knauf AMF is the material: Burgess CEP makes metal ceiling tiles, while Knauf AMF makes mineral fibre tiles such as Planet, Sand and Orbit. That single difference drives everything — durability, acoustics, appearance, cost and where each belongs. Neither is better in absolute terms; they suit different requirements. This guide compares the two ranges RCT stocks so you can choose, or correctly match, the right one.
Burgess CEP tiles are powder-coated steel — hard, durable and long-lived, with acoustics provided by perforations and a backing pad on perforated tiles. Knauf AMF tiles (Planet, Sand and Orbit) are soft mineral fibre — lighter, lower-cost, with acoustic absorption coming from the body of the tile. Metal is the more durable, premium product; mineral fibre is the more economical, widely used everyday tile.
Metal wins clearly on durability. Burgess CEP tiles resist impact, handling and general wear far better than soft mineral fibre, which dents, marks and breaks more easily. In high-traffic or demanding areas where tiles are handled often, a metal tile lasts longer and keeps its appearance — part of why so many decades-old Burgess ceilings remain in service.
The two achieve acoustics differently. A mineral fibre tile like AMF Planet, Sand or Orbit absorbs sound through its soft body across the whole tile. A Burgess metal tile relies on perforations (e.g. the D278 pattern) plus a backing pad; a plain metal tile without perforations reflects more sound. For straightforward acoustic absorption at low cost, mineral fibre is simple and effective; a perforated metal tile can perform well but the plain metal tiles are chosen more for durability and finish.
Metal gives a crisp, contemporary, wipe-clean finish with sharp edges and a consistent powder-coated surface — a more designed, premium look. Mineral fibre gives the familiar soft commercial ceiling, with finishes from the lightly textured Planet to the finer Sand and Orbit. The choice often comes down to the look the space wants and how hard-wearing it needs to be.
Mineral fibre is the more economical option. AMF Planet, Sand and Orbit are budget-to-mid commercial tiles, while Burgess CEP metal tiles cost more per tile (RCT’s Burgess range runs from around £1.49 for the budget Classcare up to the mid-teens for perforated tiles). The metal premium buys durability and finish; where neither is critical, mineral fibre is more cost-effective.
If you are matching an existing ceiling, the material decides it — replace a metal ceiling with Burgess CEP and a mineral fibre ceiling with AMF; do not mix the two in one area. For a new specification, choose Burgess CEP where durability and a premium wipe-clean metal finish matter, and Knauf AMF where a cost-effective, dependable general commercial tile is what the space needs. RCT stocks both, so a single supplier can cover whichever the project calls for.
What is the difference between Burgess CEP and Knauf AMF tiles?
Burgess CEP makes metal (steel) ceiling tiles; Knauf AMF makes mineral fibre tiles (Planet, Sand, Orbit). Metal is more durable with a premium finish; mineral fibre is more economical and widely used for general ceilings.
Which is more durable, metal or mineral fibre tiles?
Metal. Burgess CEP tiles resist impact, handling and wear far better than soft mineral fibre, which is why many decades-old metal ceilings remain in service.
Which is cheaper, Burgess CEP or AMF?
AMF mineral fibre is more economical. Burgess metal tiles cost more per tile but buy durability and a premium wipe-clean finish. RCT’s Burgess range starts from around £1.49 for the budget Classcare tile.
Can I replace a metal ceiling with mineral fibre tiles?
Not as a like-for-like match within the same area — the fixing, look and performance differ. Match a metal ceiling with Burgess CEP and a mineral fibre ceiling with AMF. A whole-area redesign is a different decision.
