PRS Fireboard is a Euro Class A1 non-combustible fire board that has been rigorously tested in many applications to both BS and EN standards proving suitability high performance passive fire protection for most specification where fire is a concern.
Key Features
PRS Fireboard has many benefits over other sheet materials
Exceptional Fire Resistance
PRS FireBoards are non‑combustible, capable of withstanding extremely high temperatures (up to 1000–1200°C) without structural failure, making them ideal for fire‑rated assemblies and high‑risk environments.
Extensive testing with Exova testing labs ensure compliance to multiple BS and EN standards.
Please see our specification document for details.
High Durability & Strength
PRS FireBoards offer excellent impact resistance, resist bending and cracking, and outperform many traditional materials such as gypsum, plywood, and cement board. Their long service life reduces maintenance and replacement costs.
Moisture & Mold Resistance
They do not absorb water, swell, or degrade in humid environments, preventing mold and mildew growth and making them well‑suited for bathrooms, basements, kitchens, and exterior sheathing.
Acoustic Performance
They provide improved sound insulation compared to many traditional wall systems, making them useful for offices, schools, multi‑unit housing, and studios.
Eco-Friendly & Safe
MgO production requires less energy and emits fewer carbon emissions than cement‑based products. PRS FireBoards contain no harmful chemicals like formaldehyde, asbestos or VOC’s contributing to improved indoor air quality.
Design Flexibility
PRS FireBoards can be easily cut, shaped, and used for curved or non‑standard designs without losing structural integrity.
​
Available in multiple thickness: 6mm, 9mm, 12mm, 15mm, 18mm. And multiple sizes from 2400x1200mm to 3000 x 1200mm.

Applications
Interior Wall Panels
Used for durable, fire‑rated interior walls in homes, offices, and commercial buildings. MgO boards accept paint, wallpaper, tiles, and laminates.
Ceiling Systems
Suitable for suspended ceilings in retail, offices, classrooms, and hospitality applications, due to the fire, mold, and moisture resistance.
Subflooring & Flooring Underlayment
Provides a stable, moisture‑resistant base under tile, wood, or vinyl flooring—ideal for kitchens, bathrooms, and wet zones.
Exterior Sheathing & Cladding
Used for weatherproof exterior facades, soffits, and sheathing thanks to its resistance to moisture, mold, and temperature changes.
Fire‑Rated Doors & Partitions
Acts as a core material in certified fire‑rated partitions and doors, providing thermal stability for up to two hours.
Acoustic Panels
Applied in theaters, studios, offices, and educational buildings to reduce sound transmission while maintaining fire resistance.
Cladding & Exterior Façades
Serves as durable Fire resistant substrate material for exterior facades.
Structural Insulated Panels (SIPs)
PRS FireBoards can be used as facings for SIP systems, adding fire, moisture, and insect resistance.
Firewalls, Shafts, Stairwells, and Commercial Applications
Installed in fire‑rated systems requiring stringent safety standards (e.g., stair enclosures, service shafts). Ideal for high‑traffic zones such as hospitals, schools, and commercial spaces due to impact resistance, fire resistance and durability.
