SANDSTONE Fire Resistant A1 Inorganic Ceramic Foam Board for Highrise Facade Cladding

On projects where the facade strategy is driven by fire safety, this fire resistant sandstone ceramic foam board provides a Class A1 non-combustible surface without relying on organic binders or coatings. The 40mm inorganic body contributes no fuel load to the wall assembly and does not generate dense smoke in a fire event.

The board also answers the practical question of insulation. A thicker ceramic core raises thermal resistance, so the same panel satisfies fire compartment requirements and reduces heat transfer, while the sandstone face supplies the architectural finish that would otherwise be added as a separate stone layer.

• Class A1 non-combustible, tested to GB 8624
• Fully inorganic foamed ceramic without combustible binder
• 40mm thickness raises thermal resistance across the envelope
• Lightweight porous structure suits high rise application
• Water absorption of 0.6% resists frost and driving rain
• Sandstone decorative face removes the need for extra cladding

• High rise building facades with strict fire codes
• Fire compartment walls and protected escape routes
• Public buildings such as schools and hospitals
• Industrial facades requiring non-combustible cladding

Fire rated assemblies demand disciplined installation. The fire resistant sandstone ceramic foam board is fixed continuously to a non-combustible substrate, with joints staggered and penetrations sealed using approved intumescent details. Because the panel is inorganic, no additional flame barrier is needed behind it, which simplifies the wall build-up and keeps the certified assembly easy to inspect at handover.

Boards are stacked face to face on timber pallets, corner protected and strapped, with batch certificates placed inside each pallet so the site team can match panels to the approved fire report on delivery.
