Natural stone cladding supplier to the UK trade.

Karpat supplies the natural stone for cladding projects — marble cladding, travertine and limestone in slab, tile and cut-to-size formats, quarried in Turkey and delivered duty-paid to the UK trade. We are the material supplier: we provide stone cut and finished to your cladding specification, with the test data your facade engineer or fixing-system specialist needs. We don't design or install the support system — we make sure the stone arriving on site is right.

What we supply — and what we don't

Material to spec, documented.

• We supply — natural stone cut to your cladding panel schedule (size, thickness, edge/kerf detail), in the material and finish specified, with samples approved first.
• We document — BS EN 1469 (cladding slabs) test data, CE Declaration of Performance, and proof of Turkish origin, so the material satisfies the project's compliance file.
• We don't — design the façade system, supply the fixing/anchor system, or carry out installation. We work to your façade engineer's drawings and fixing specification.

CE marking is recognised for construction products placed on the Great Britain market (no UKCA retest needed). We deliver duty-paid in GBP, or supply CFR/CIF for buyers with their own forwarders.

How we source

To your drawings & specification.

Send the material, panel schedule, thickness, finish and quantity — ideally with the façade specifier's fixing/kerf detail. We approach the relevant producers on your behalf, return comparative offers within three working days, and dispatch samples ahead of order confirmation. Every shipment carries proof of preferential origin (declaration on origin, or EUR.1), CE Declaration of Performance, and BS EN 1469 test reports.

Specification & supply

Cladding formats, loads and lead times.

We supply the stone for cladding — cut to your contractor's schedule — in marble, travertine and limestone. Fixing design and engineering stay with the façade contractor.

Container loads

Stone loads by weight, not volume: a 20 ft container carries about 25 tonnes, so thickness sets how many square metres fit. Figures are approximate and confirmed line by line on every quotation.

Supply

• Lead time — stock items about 2–3 weeks order-to-door, cut-to-order 5–6 weeks, bespoke 6–10 weeks; a firm window comes with every quote (trade terms).
• Samples — a sample pack goes out with the quotation, and before shipping we send photographs and a slab or crate list of the actual material allocated to your order.
• Delivery & offload — delivered duty-paid to your yard or site and invoiced in GBP. Crates and bundles are offloaded by your forklift as standard; truck-mounted forklift or crane can be arranged. You can also collect from our warehouse at the Port of Tilbury or the Port of Liverpool.
• Ordering — from project quantities to full 20ft containers; smaller orders travel by groupage, and containers can be mixed across colours, sizes and finishes. 60% with order, 40% against shipping documents within 3 banking days.

Common questions

Stone cladding — what UK buyers ask.

Which stones are used for external cladding?

Denser marbles, travertines and limestones chosen for the exposure, in sawn or split-face panels. We match the stone to the façade and supply the test data the specification asks for.

How are cladding panels fixed?

Stainless mechanical fixings or an approved adhesive system, designed by the façade engineer or contractor. We supply the stone cut to their schedule, thickness and edge detail.

How heavy is stone cladding?

Marble weighs about 27 kg per m² for every 10 mm of thickness, so a 30 mm panel is roughly 80 kg per m². Travertine and limestone are 5–10% lighter.

Can we approve the stone first?

Yes. Samples come with the quotation, and we send photographs of the actual production before shipping.
