Laminam 12+ Laminam 12+ is a large-format, (12mm & 20mm) porcelain slab available in lengths up to 128”. It’s a suitable alternative to many of the quartz-based countertops available today, due to the material’s durability, stain resistance and burn resistance, as well as the quality of the printing (particularly with natural stone looks). As a colorfast material, it’s resistant to fading, making it suitable for exterior kitchen and countertop applications. Laminam 12+ can also be used in showers and other wet areas.
