Eurocell, renowned for its high-performing Modus and Logik window and door systems, partnered with illbruck (a brand of Tremco CPG UK) to tackle a crucial, underestimated installation challenge – the ‘integration junction’. This critical connection between window systems and building facades plays a vital role in a building’s thermal efficiency and long-term durability, especially under extreme weather conditions.
Together, they set out to develop a high-performance, resilient solution that would redefine industry standards for commercial buildings. By integrating Eurocell’s certified window systems with illbruck’s leading-edge sealing solutions, this collaboration promises to transform how commercial facades withstand the elements.
Collaborative problem-solving
Leveraging combined expertise, Eurocell and illbruck aimed to set a new benchmark for resilience and energy efficiency. By pairing Eurocell’s Modus and Logik systems with illbruck’s advanced i3 sealing solutions, they created a seamless, high-durability connection that not only meets but exceeds European standards for air permeability and water tightness.
This breakthrough solution anticipates the stricter requirements of future regulations, setting the stage for a new standard in commercial building façades.
Unmatched testing and validation
In August 2024, Eurocell and illbruck put their collaborative solution to the test in Tremco CPG Europe’s state-of-the-art research facility in Bavaria, Germany. By installing the systems within concrete frames, they replicated real-world conditions to validate durability and resilience.
Rigorous testing in line with EN 1026 (air permeability) and EN 1027 (watertightness) examined the critical window-to-wall junction as well as the full system, proving this solution’s capability to withstand the demands of real-world application.
Exceeding industry standards
The results demonstrate a solution that outperforms expectations, providing builders and developers with unmatched peace of mind – the results included;
- Driving rain resistance: Withstood driving rain at 600 Pa, delivering robust protection against water ingress in extreme weather.
- Airtightness: Achieved an impressive airtightness rating of <0.1 m³/(m·h·daPa²/³), meeting Class 4 under the UK’s BS EN 12207:2016 standard.
- Thermal efficiency: Enhanced integration with Tremco’s sealing solutions minimised air infiltration, raising the bar for energy performance in commercial facades.
This solution not only addresses current needs but anticipates future demands, ensuring high resilience and superior energy performance.
A breakthrough full-system solution for diverse applications
The Eurocell and illbruck partnership has produced a comprehensive system that surpasses Building Regulations and Passivhaus standards for air permeability. This adaptable, high-performance solution is suited for various building types, from high-rise developments to commercial projects in harsh weather environments.
By addressing both airtightness and thermal bridging at the junction level, this integration supports sustainable construction goals, reducing energy costs and emissions across the UK.
Industry perspectives
Kelly Hibbert, Head of Commercial at Eurocell, shared her enthusiasm on the outcomes of the work with illbruck:
“Eurocell is committed to advancing a more sustainable construction industry by delivering window systems that meet the demands of a changing world. Working with illbruck has allowed us to create a truly integrated solution that brings lasting benefits to both the industry and building occupants. This partnership exemplifies how we can collectively raise standards and provide innovative products that balance performance with environmental responsibility.
“Through this collaboration, we are better equipped to support builders and developers with high-performance solutions that contribute to the efficiency and sustainability of their projects, from insulation to carbon reduction. It’s a project that speaks to our shared vision for a more resilient, energy-efficient future in the built environment.”
Similarly, Steve Wild – Technical consultant at Tremco CPG added: “The i3 system optimises both airtightness and thermal insulation, enhancing building resilience and energy efficiency. Partnering with Eurocell reflects our dedication to pioneering standards and providing builders with an integrated, top-tier solution for today’s construction challenges.
“Together, we’re delivering solutions that make it simpler for the industry to adopt practices that reduce energy use and operational costs. This collaboration stands out as an example of our commitment to sustainable growth, giving construction professionals access to advanced materials that are also practical and cost-effective.”
