Grespania continues to redefine architectural surfaces with ultra-thin, large-format porcelain tiles that are suitable for both interior and exterior spaces, blending beautiful design with an eco-conscious approach. Designed for contemporary architecture and interior design, Coverlam represents the evolution of porcelain: lighter, stronger, and engineered with respect for the planet.
Large-format technical stone represents the next evolution in architectural surfaces - an engineered material created from a precise blend of natural minerals and advanced compounds. Compacting under 30,000 tons of pressure and firing at over 1,200 °C fuse these components into ultra-dense slabs of exceptional strength and stability. The result is a lightweight, non-porous material that illustrates the natural beauty of stone with the superior performance, and sustainability demanded by future forward architecture and Grespania as a company.
Technical Features include:
Durability
Stain Resistance
UV Resistance
Heat Resistance
Hygiene
Design Versatility

Sustainability For The Future
Coverlam was conceived not only as a technical innovation but as a sustainability statement. Produced using more than 90% natural raw materials, and with a manufacturing process powered by renewable energy and closed-loop water recycling, Coverlam, as a product, clearly demonstrates how innovation can lead to meaningful reductions in environmental impact. Its thickness - at just 3.5 mm or 5.6 mm - means up to three times less raw material is required and significantly lower transport emissions are produced compared to traditional porcelain.
Every square metre of tile reflects reduced energy use, waste and resource extraction - proving that genuine design innovation can go hand in hand with a care for the environment. Grespania’s manufacturing facilities operate under stringent environmental management systems, they provide ceramic solutions that optimise efficiency and comply with the most demanding environmental standard, this is key. The result is a product line that supports LEED, BREEAM, and other sustainable building certifications internationally recognised, giving architects measurable environmental performance data they can trust.
Facades That Benefit
When used in a ventilated facade system, Coverlam becomes an environmental gain. The ultra-thin slabs, measuring up to 1200 × 3600 mm, form a durable exterior layer that allows air to circulate between the wall and the façade. This natural ventilation reduces thermal bridges, reflects solar radiation and regulates building temperature, cutting energy consumption for both heating and cooling. There is an additional acoustic improvement with noise reduction throughout.
Even more remarkably, façades finished with the H&C Tiles photocatalytic coating from Grespania actively purify the air. The titanium-dioxide treatment reacts with sunlight to break down nitrogen oxides (NOx) and organic pollutants, effectively transforming building surfaces into self-cleaning, air-purifying membranes.
According to Grespania’s data, 10,000 m² of treated façade neutralises as much NOx as 740 cars emit daily, equating to the purifying power of nine football pitches of green space. This dual benefit of reduced building energy demand and active air purification—making Coverlam the ideal choice for forward-thinking, sustainable architecture and design.
Technical Excellence
Behind Coverlam’s refined surface aesthetics lies robust engineering. Its porcelain composition achieves water absorption below 0.1%, delivering a high resistance to frost, UV exposure, and pollution. Despite its ultra-thin profile, it offers exceptional flexural strength thanks to its reinforced fibre mesh backing, ensuring durability in both new-build and renovation projects. It is lightweight and easy to install which allows facades and interiors to be transformed without the need for structural reinforcement or demolition, reducing waste and installation time.
The material is certified under ETA 24/0747, confirming its performance for exterior facades, cladding, and flooring. The large-format slabs allow seamless coverage and minimal joints, creating a calm, continuous surface that highlights the precision of contemporary architecture. The clever combination of proportion, scale, and natural finish gives designers freedom to explore materiality without compromise.
The Concepts Collections: A Unified Vision
Grespania’s Concepts Collections is inspired by a holistic design philosophy - coordinating surfaces, furniture, and architectural elements through a shared material language. Each collection offers multiple finishes, thicknesses, and applications, ensuring design continuity across all spaces. The Imperium series, for example, reflects the beauty and sophistication of marble with fine veining and a luxurious polish; it is available in formats up to 1600 × 3200 mm for large, uninterrupted flowing expanses. Meanwhile, Coverlam Top extends this concept for kitchens and furniture, offering 10 mm and 12 mm thicknesses for countertops, tables, and bespoke joinery allowing for a coherent design flow. Each tile is designed for ease of handling, the mineable side and weight of each tile enables ease of installation. Perfectly suitable for single-person installation allowing for improved efficiency on-site. This integrated approach allows architects and designers to create interiors and exteriors that continuously flow fluently - stone, metal, or cement effects translated across floors, walls, facades, and furnishings.
Design But Make It Lighter
Beyond its visual impact and endless design possibilities, Coverlam’s sustainability credentials are tangible. Its thin profile reduces CO₂ emissions from production and transport, while its long lifespan and low maintenance requirements further cut environmental impact over time. The ventilated facade system improves building performance, acoustic insulation and protects structures from weathering. Simultaneously, the self-cleaning surfaces maintain their aesthetic integrity with minimal upkeep - rainwater naturally washes away dirt and surface pollutants. Through balancing technical performance, ecological advances, and design versatility, Coverlam proves that sustainability does not require an aesthetic compromise. It represents a material evolution aligned with the architectural priorities of our time: durability, lightness, and responsibility.
A Material For The Next Generation Of Architecture
As cities grow denser and environmental regulation grows, the materials we specify matter more than ever. Coverlam’s contribution goes beyond form and function - it plays an active role in the shift toward carbon-conscious design. Each facade or interior finished in Coverlam becomes part of an architectural ecosystem that generates less waste, consumes less energy, and even cleans the air we breathe. Whether creating a serene interior or shaping a landmark facade, Coverlam stands as proof that the future of architecture lies not only in what we build, but in how we build it.
