Honed Natural Vein Surface 40mm Ceramic Insulation Panel Class A1 Non-combustible Marble Glazed Ceramic Panel for Curtain Wall Spandrels

A curtain wall spandrel has to read as stone from the street while staying inside the weight and tolerance budget of the facade contractor. This honed marble look ceramic cladding panel is a 40 mm sintered body with a natural vein surface, about 10 kg/m², and it is cut and drilled in the factory so site work is assembly rather than stone carving.

The honed surface scatters light instead of reflecting it, which matches the appearance of a honed marble slab and hides handling marks on large elevations. Because the vein is fired into the body, adjacent panels can be sequenced for a continuous vein without the batch variation of natural stone.

• Class A1 Fire Performance: This honed marble glazed ceramic insulation panel 40 mm natural vein surface is non-combustible from surface to core to GB 8624, with no dripping, no heavy smoke and no toxic gas release, which suits curtain wall spandrels, column casings and exterior soffits.
• Fired-in Marble Pattern: The honed natural marble vein is generated in the body at 1200 °C, so it does not peel, chalk or fade like a printed or coated surface.
• Low Dead Load: About 10 kg/m² at 40 mm, roughly one quarter of a 30 mm marble slab, which keeps anchors, keel steel and crane time down.
• Stable Colour Lot to Lot: A fixed pigment recipe and firing curve hold the honed natural marble vein inside the approved tolerance on repeat orders.
• Weather and Pollution Resistance: Closed cells and a sintered skin resist water penetration, 25 freeze-thaw cycles and urban staining; cleaning needs water, not chemical stone restorers.
• Factory Cut to Spandrel Schedule: Panels are cut, labelled and packed to your spandrel schedule, so each unit arrives with its position and grain direction marked.

• Curtain wall spandrel panels between vision glass
• Column casings and aluminium profile surrounds
• Exterior soffits and canopy fascias
• Entrance portal cladding on commercial towers
• Parapet and roof edge feature bands

Spandrels are fixed with stainless back-groove anchors into an aluminium subframe that is set out with the curtain wall grid. Allow a 12–15 mm joint, use EPDM gaskets against the glass pocket, and keep the panel face protected until the facade is cleaned down.

The honed marble glazed ceramic insulation panel 40 mm natural vein surface is supplied on plywood pallets with PE film, corner protection and edge guards, about 1.2 tons per pallet, loaded into 20 ft or 40 ft containers with fumigation-free packing. Store under cover, keep pallets level and avoid point loads on the decorated face. Special sizes, corner pieces and window returns can be produced to drawing.
