Ecofacade Prefabrication TrueSeal

Precision-Molded Sealing for Advanced Façade Details

Sealing complex penetrations and intricate façade details within prefabricated frames can be one of the most challenging and error-prone tasks in façade construction. Effisus True Seal offers a high-performance 3D vulcanized solution engineered specifically to address these demanding areas with precision and reliability.

Complex geometries

Curtain walls and glass facades

Architectural details such as those found in rainscreen cladding systems, service penetrations, brackets, anchors, or irregular frame junctions typically require multiple sealing steps, custom cutting, and high installer expertise. This traditional approach increases installation time and introduces substantial risk of human error, leading to potential leaks and costly rework.

Effisus True Seal replaces these complex, multistep procedures with a single EPDM moulded, high tech component designed to fit the exact geometry of each project detail. Its robust 3D vulcanised structure ensures consistent performance, full adaptability, and long term durability. By simplifying installation and eliminating onsite improvisation, True Seal dramatically increases reliability and enhances the overall quality of both prefabricated and onsite facade assemblies.

The result: a highly efficient, long lasting sealing solution that transforms intricate facade transitions and penetrations into secure and resilient elements every time.
