Frequently Asked Questions

Each order of Petra™ Ceiling Tiles comes in boxes of 20 tiles. The tiles are designed for use with a standard suspended ceiling grid system and require no additional fixings. Installation is straightforward — simply place the tiles into the ceiling grid. Please note that the ceiling grid system is not included and must be purchased separately unless arranged otherwise.

We currently do not sell ceiling grid systems directly online, but we are working to include this option. If you require a ceiling grid for your Petra™ Ceiling Tiles, please contact us. Our team can recommend compatible systems and assist with sourcing, ensuring your installation process is smooth and efficient.

Petra™ Ceiling Tiles are designed to transform your environment by significantly reducing noise and echo. Their superior acoustic performance improves speech clarity, reduces distractions, and creates a calmer, more comfortable atmosphere. This makes them ideal for busy offices, schools, restaurants, healthcare facilities, and other professional environments where acoustic comfort is essential.

Currently, Petra™ Ceiling Tiles are available in standard shapes and sizes, with colour options in white or black. However, we understand that every project is unique, and bespoke options may be required. For larger-scale or specialist projects, we can explore custom shapes, sizes, and colours to meet your design needs. Please contact our team with your project details so we can provide tailored advice and availability.

Our Petra™ tiles are designed to fit standard suspended ceiling grids, including both square and tegular edge options. This compatibility makes installation simple and seamless while ensuring a polished, professional finish. For unusual or bespoke grid requirements, please consult our team for compatibility guidance.

Petra™ Ceiling Tiles have been tested in accordance with GB/T16731–1997 and deliver an impressive Noise Reduction Coefficient (NRC) of 0.90, which is equivalent to a Class A sound absorption rating — the highest level of acoustic performance available. This means they are highly effective at absorbing sound and reducing noise in busy environments.

Yes — Petra™ Ceiling Tiles feature a special paint coating that helps prevent dust accumulation. For optimal maintenance:

Regularly clean ventilation systems, as they are a primary source of dust, dirt, and oil contamination.
Do not wash tiles with excessive water or detergent.
For minor stains or fingerprints, gently scrub with an eraser.
Use a soft brush or vacuum with appropriate power to remove dust. Vacuum in the same direction as the surface pattern to avoid damaging the finish.
For fabric surfaces, dust and vacuum regularly. Spot clean with a damp sponge and mild detergent when necessary. Full washing is not recommended.
Cleaning is typically recommended every month to maintain appearance and performance.

Petra™ Ceiling Tiles are manufactured to precise tolerances. Each tile is slightly smaller than its nominal size to ensure a perfect fit in ceiling grids. For example:

Nominal size: 600×600 mm → Actual size: 593×593×15 mm

The tiles are 15mm thick, providing a balance between acoustic performance and aesthetic appeal.

Petra™ Ceiling Tiles meet the highest safety standards with a Reaction to Fire classification of GB 8624 A (A2-s1,d0). This ensures they are suitable for a wide range of commercial and public spaces.

No — Petra™ Ceiling Tiles come with a specially coated finish that cannot be painted without compromising their acoustic performance and surface integrity. If colour customisation is important for your project, please contact us to discuss bespoke colour options.

600×600 mm tiles: 20 tiles per box, covering 7.20 m² per box (0.36 m² per tile).
1200×600 mm tiles: 20 tiles per box, covering 14.40 m² per box (0.72 m² per tile).

There is no minimum order quantity for Petra™ Ceiling Tiles — they are sold per box.

With proper maintenance and care, Petra™ Ceiling Tiles are designed to deliver long-lasting acoustic performance and visual appeal for many years. Their durable construction and high-quality materials make them a reliable solution for both commercial and residential projects.
