Knauf Mediguard Plain Tegular24 600mm x 600mm Ceiling Tiles - Box of 16

Knauf Mediguard Plain Tegular24 ceiling tiles combine a smooth, anti-microbial surface with a rebated edge designed for 24mm exposed suspended ceiling grid. Developed for hygiene-sensitive environments, they provide a clean white finish for healthcare facilities, laboratories and other commercial spaces where cleaning and maintenance are key considerations.

Part of our Knauf AMF ceiling tiles range, this 600mm x 600mm tile has a stepped edge that allows the tile face to sit below the visible grid, creating a defined reveal around each panel. Browse our tegular edge ceiling tiles for other tiles with this recessed grid appearance.

Key Features

• Tegular24 rebated edge: Creates a stepped ceiling finish beneath a compatible 24mm exposed grid.

• Practical cleaning: Suitable for dry, damp and wet cloth cleaning, with resistance to disinfectants.
• Durable surface: Water-repellent and scratch-resistant.
• Hygiene performance: ISO 4 clean room classification and Zone 4 risk performance to the standards listed below.
• Light reflectance: 88% to help distribute light within the room.
• Humidity resistance: Up to 95% RH.
• Reaction to fire: Euroclass A2-s1, d0.
• Pack quantity: 16 tiles, providing 5.76m² nominal coverage before cutting and wastage.

What Does Tegular24 Mean?

Tegular24 describes a rebated ceiling tile edge designed to sit on grid with a 24mm-wide exposed face. The tile's perimeter rests on the grid while the main tile face projects below it, giving the ceiling more depth than a flat board edge finish.

Choose this version when your project requires a reveal-style ceiling on a compatible 24mm grid. For existing ceilings, check a removed tile before ordering: a 600mm x 600mm module alone does not identify the correct edge detail.

Applications and Hygiene Performance

Mediguard Plain is designed for healthcare environments and laboratories where a cleanable, anti-microbial ceiling surface is required. It is an option within our hygienic ceiling tiles and hospital ceiling tiles ranges.

• Hospitals and healthcare facilities
• Medical clinics and treatment areas
• Laboratories and research facilities
• Controlled environments requiring specified hygiene performance

The manufacturer declares ISO 4 clean room performance to EN ISO 14644-1 and compliance with Zone 4 Very High Risk requirements to NF S 90-351:2013. Individual rooms also have specific cleanability and air leakage requirements, so these classifications do not automatically make the tile suitable for every Zone 4 room. Confirm the complete ceiling specification against the intended application.

Performance figures are manufacturer-declared values for Mediguard Plain under the relevant test conditions. Euroclass A2-s1, d0 is a reaction-to-fire classification, not a fire-resistance duration for a complete ceiling assembly.

Anti-Microbial Surface and Cleaning

Mediguard Plain's surface helps limit microbial growth and supports routine cleaning in hygiene-sensitive spaces. The manufacturer's datasheet lists testing against bacteria and fungi including Escherichia coli, Staphylococcus aureus, Bacillus cereus, Streptococcus pneumoniae, Klebsiella pneumoniae, Candida albicans and Aspergillus brasiliensis.

Tiles can be cleaned using dry, damp or wet cloths. Follow Knauf's cleaning guidance when selecting disinfectants and cleaning methods.

Choosing a Compatible Ceiling Grid

Use this tile with a compatible 24mm exposed grid system arranged for 600mm x 600mm modules. Explore our AMF ceiling grid systems and Donn suspended ceiling grids, selecting the appropriate 24mm system for your project.

Grid selection should also account for loading, perimeter details and the environmental requirements of the room. Keep grid components within a compatible manufacturer-approved system.
