SANDSTONE Lightweight Porous Ceramic Foam Facade Panels Curtain Wall Retrofit Systems

The lightweight sandstone ceramic foam panel weighs about 7.6 kg per square metre, roughly a tenth of natural sandstone cladding of the same thickness. That difference decides feasibility on curtain walls, cantilevered canopies and buildings where the structural allowance for facade load is already fixed.

Thin 20mm sections also change site practice. Panels can be carried and positioned by two installers without lifting equipment, joints stay tight on vertical runs, and the sandstone face is already finished when the panel leaves the pallet, so the facade closes faster.

• Low 380 kg/m³ density cuts facade dead load
• 20mm slim panel handles easily without lifting gear
• Class A1 non-combustible inorganic ceramic body
• Porous structure provides reliable thermal insulation
• Water absorption of 0.6% for a long service life
• Sandstone look finish replaces quarried stone veneer

• Curtain wall cladding with tight load allowances
• Facade retrofit and over cladding of existing walls
• Canopies, soffits and lightweight architectural features
• Prefabricated facade units assembled off site

Lightweight panels change handling but not the fixing principle. The 800x400x20mm sandstone ceramic foam panel is set out from a corner, bonded to a levelled substrate with adhesive ribs, and mechanically secured at the panel perimeter where the specification requires it. At about 7.6 kg per panel, one installer can place and adjust the unit, which shortens scaffold time and reduces the crew size needed for a facade elevation.

Shipment uses foam corner protectors and edge boards on timber pallets, strapped and shrink wrapped. Each pallet is labelled with model, thickness and quantity, so lightweight panels can be distributed floor by floor without restacking on site.
