Fassa Bortolo has long been synonymous with tradition, technical expertise and uncompromising quality, and its latest achievement marks a significant milestone for both the company and the wider construction industry.
Fassacouche, the brand’s flagship monocouche render, has officially been awarded the prestigious Kiwa BDA Agrément “Very Severe” certification—a distinction that recognises only the highest-performing external renders capable of withstanding the toughest environmental demands.
This new accreditation not only reinforces Fassacouche’s position as a market-leading render system, but also offers architects, contractors, and specifiers an even greater level of assurance in challenging build scenarios.
The “Very Severe” certification is reserved for products that demonstrate exceptional durability, adhesion, water resistance, and weather protection, particularly in regions exposed to persistent wind-driven rain, harsh coastal conditions, or fluctuating temperatures. Fassacouche has undergone an extensive and rigorous testing programme, including assessments of strength, thermal performance, moisture behaviour, and long-term resilience. The achievement of this classification affirms that the product exceeds the stringent criteria necessary to ensure structural protection and aesthetic longevity, even in the most demanding settings.
For professionals specifying external finishes, this certification represents more than a technical endorsement—it is a guarantee of reliability. Fassacouche’s robust composition, combined with Fassa Bortolo’s advanced manufacturing processes, delivers excellent workability on site, consistent curing, and a clean, crisp finish across both traditional and contemporary façade designs. It is a system that balances design freedom with outstanding technical integrity, enabling buildings to perform as beautifully as they appear.
In addition, this accreditation underscores Fassa Bortolo’s commitment to continuous improvement and innovation. The company has invested heavily in research and development, ensuring its materials not only meet but surpass modern performance standards. Fassacouche’s enhanced classification is a testament to this ongoing dedication, reflecting a product range that evolves with the industry while remaining rooted in the craftsmanship that has defined Fassa Bortolo for more than three centuries.
The certification also offers significant benefits to contractors. With Kiwa’s “Very Severe” rating, Fassacouche provides confidence in long-term performance, reducing maintenance needs and mitigating risk over the lifespan of the building. Installers can rely on a system that behaves predictably, applies efficiently, and resists the stresses of both climate and time.
For end clients and homeowners, the accreditation assures peace of mind. Whether used on a coastal property, a high-exposure hillside home, or a large-scale housing development, Fassacouche delivers enduring protection without compromising aesthetics. Its resilient formulation supports a façade that stays true to colour, resists cracking and maintains its visual appeal year after year.
Ultimately, the Kiwa “Very Severe” certification represents a new chapter for Fassacouche - one built on trust, performance, and the pursuit of excellence. Fassa Bortolo continues to set industry standards, offering products that not only withstand the elements but elevate the expectations of what modern renders can achieve. With this latest recognition, Fassacouche firmly establishes itself as a leader in high-exposure external finishes, ready to meet the challenges of the built environment with exceptional strength and style.
