• Upping The Junction

Eurocell has partnered with Tremco Illbruck to tackle an underestimated installation challenge – the ‘integration junction’. This is the critical connection between window systems and building façades.

It plays a vital role in a building's thermal efficiency and long-term durability, especially under extreme weather conditions.

Eurocell produces the Modus and Logik window and door systems. Tremco Illbruck produces sealant solutions for both commercial and domestic applications. Together, they set out to develop a high-performance, resilient solution that would create a new standard for commercial buildings.

 

Air & water

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.

 

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.  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 combinations withstood driving rain at 600 Pa, delivering robust protection against water ingress in extreme weather.

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.

Enhanced integration with Tremco’s sealing solutions minimised air infiltration, raising the bar for energy performance in commercial facades.

The partnership has produced a comprehensive system that surpasses UK 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.

Kelly Hibbert, the head of commercial at Eurocell, says: “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.”

Steve Wild, a technical consultant. at Tremco CPG adds: “The i3 system optimises both airtightness and thermal insulation, enhancing building resilience and energy efficiency. Partnering with Eurocell, we have pioneerd standards and provided installers with an integrated, top-tier solution for today’s construction challenges.”
