FerroFinestra T42 TB is a thermally enhanced system inspired by classical solutions of the past century. Unlike conventional façade profiles, these T-shaped mullions integrate the thermal barrier directly into the profile achieving a very high thermal insulation in a reduced sightline. The system follows the concept of partitioning systems and there is no need for special glass fixings components. All kind of window or door elements can be integrated into these mullions. Glazing follows the same principles of windows. The T shape aesthetics makes it ideal for restoration as well as for new cutting edge architecture. Available in steel, cor-ten steel and stainless steel.
