The ARDOGRES® BIANCO OSTUNI 40X40 porcelain stoneware roof tile represents one of the most innovative roofing solutions ever developed by Ardogres and one of the most advanced “cool roof” systems currently available on the international market. Introduced as a major Ardogres innovation for 2024/2025, it combines high solar reflectance, advanced energy performance and exceptional architectural aesthetics in a product unlike any other in the roofing industry.
Inspired by the traditional white architecture of Southern Europe and the Mediterranean — from the whitewashed houses of Puglia and Ostuni to the iconic white roofs of Greece and coastal villages exposed to intense solar radiation — BIANCO OSTUNI has been specifically developed to improve summer thermal comfort and reduce building overheating naturally.
For centuries, white roofs and white façades have been used throughout Mediterranean architecture as a passive cooling solution capable of reflecting sunlight and limiting heat absorption during hot summers. ARDOGRES® BIANCO OSTUNI reinterprets this architectural tradition through advanced porcelain stoneware technology and ultra-high-definition digital graphics.
Unlike conventional white roofing materials, BIANCO OSTUNI combines a refined natural stone appearance with a bright mineral white surface, maintaining the elegance and texture of stone while delivering outstanding solar reflectance performance.
Thanks to exclusive Ardogres HDT (High Definition Technology) digital inkjet printing, the tile achieves an exceptionally realistic structured stone surface while preserving all the technical advantages of high-performance porcelain stoneware. This combination of ultra-realistic graphics, structured texture and solar-reflective performance makes BIANCO OSTUNI a truly unique roofing product worldwide.
Certified laboratory tests carried out by Certimac (Faenza, Italy) confirm the exceptional thermal and solar performance of the tile:
- SRI – Solar Reflectance Index: 77/100
- Solar Reflectance: 0.63
- Thermal Emissivity: 0.91
These values allow the roof to reflect a significant portion of solar radiation, reducing heat accumulation and improving the thermal efficiency of the building envelope. The result is lower roof surface temperatures, reduced cooling demand and improved indoor comfort during summer periods.
BIANCO OSTUNI 40x40 is particularly suited for:
- energy-efficient homes
- passive houses
- Mediterranean architecture
- sustainable and low-carbon buildings
- contemporary white architecture
- Green Homes 2030 projects
- ventilated façades and cool roof systems
- modern villas and coastal architecture
- renovations requiring improved thermal performance
The tile also contributes to mitigating the urban heat island effect by reducing solar heat absorption in densely built environments.
In addition to its energy performance, BIANCO OSTUNI offers all the technical advantages of ARDOGRES® porcelain stoneware roofing systems:
- extremely low water absorption (<0.5%)
- frost resistance and freeze-thaw durability
- resistance to UV exposure, hail, abrasion and chemical attack
- colour stability over time
- lightweight roofing system
- minimal maintenance requirements
- 50-year warranty
- expected lifespan exceeding 100 years
The mechanical fixing system using screws and slotted holes allows installation without glues or adhesives, making the roof fully removable, reusable and recyclable at the end of its life cycle. This makes BIANCO OSTUNI a highly sustainable roofing solution aligned with modern circular construction principles and future European “Green Homes 2030” requirements.
Suitable for both roofing and ventilated façades, ARDOGRES® BIANCO OSTUNI 40x40 offers architects, designers and homeowners a rare combination of aesthetics, sustainability, thermal efficiency and long-term durability — redefining the concept of high-performance architectural roofing for the future.
