-Tenera Ultra-
Description & Features
Tenera Ultra is a soft design in Coante's Ultra series, with beige veins that give the white a warm, calm mood. On a brilliant, almost pure white background, the veins form lacy, fragmented clusters in a light beige-grey tone: a broad band crosses the upper part of the slab, while finer branches spread towards the centre and the base. It is the same composition as Calacatta Riviera, here in a warm version instead of grey-blue. Coante produces its quartz in Muğla with Breton technology and holds, among others, ISO 9001 and ISO 14001 certification and CE marking; the material is non-porous: water absorption stays below 0.07%, flexural strength exceeds 35 MPa, hardness is 7 Mohs and abrasion resistance falls in class A4. Slab sizes are 330 × 164 cm (Jumbo) or 310 × 152 cm (Medium), with a thickness of 15, 20 or 30 mm and a polished or leather finish. It works equally well on a modern kitchen island or in a classic bathroom, as well as on countertops, wall cladding and splashbacks. A damp cloth is enough for care; stubborn stains are cleaned with a neutral cleaner, while abrasives, solvents and oven cleaners should be avoided.
