One of the main features of the insulated, drained and ventilated Facade TB50 curtain wall system is its multiple choice of mullions and transoms allowing the designer to achieve large spans whilst maintaining 50mm sight line. The isolator insert gives the profiles excellent thermal and acoustic properties. Facade TB50 can achieve a U value of 1.9 Wm²/K. The system is available in dual colour. The TB50 system has been weather tested and complies with the mandatory CE mark in accordance with the new EU Directive EN 13830. These tests were carried out in accordance with Centre for Window and Cladding Technology (CWCT) test methods.
