In the evolving world of insulating glass, progress demands flexibility and innovation. FENZI Group leads this evolution with advanced solutions that boost efficiency, precision and creative freedom. Among its top technologies, Butylver TPS and Thermoflex set new standards for modern IGU production.
Butylver TPS: The evolution of warm-edge technology
Butylver TPS marks a significant step forward in the production of insulating glass units for both residential and large-scale structural projects. Developed by FENZI, this four-in-one thermoplastic warm-edge spacer combines PIB and integrated desiccants to achieve ultra-low thermal conductivity, exceptional gas and moisture barrier performance, and durable adhesion to glass.
Designed for seamless integration with automatic applicators, Butylver TPS enables a fully automated production cycle that enhances precision, minimises waste, maximises productivity, and ensures consistent quality across every unit.
Certified with EN 1279, ASTM E2189, ASTM E2190, UNI, RAL 520 and now CEKAL validated, Butylver TPS is trusted by manufacturers worldwide, it stands as a benchmark of reliability and efficiency for automation-driven IGU manufacturing.
Thermoflex: Redefining flexibility in design
Thermoflex, FENZI’s flexible warm-edge spacer, is engineered from high-performance elastomeric foam rubber.
Fully compliant with EN 1279 and E2190-10 standards, it is free from volatile components and offers one of the lowest thermal conductivity values in its category.
Its highly adaptable structure makes it ideal for curved or non-standard window shapes, providing excellent adhesion and compatibility with all sealants and production systems.
Whether integrated into automated lines or used for bespoke architectural projects, Thermoflex delivers the perfect balance between design freedom and precision.
Innovation with a clear vision
Through Butylver TPS and Thermoflex, FENZI continues to shape the future of insulating glass technology on a global scale.
From improving productivity to empowering bold, creative architectural concepts, FENZI’s innovations embody the perfect blend of performance, versatility, and sustainability, driving the glass industry toward a more transparent and efficient future.
