tb50-cfvDesigned to be used in our Façade TB50 system this thermally broken insert sash does not interrupt the sight lines of the curtain wall grid. Designed to be concealed this thermally broken top hung open out sash is fully tested to BS6375 and comes complete with a multipoint locking mechanism. The use of multiple polyamide strips and three gasket barriers achieve a thermal enhancement, which helps to maintain a low U Value rating for façade design. The insert sash and glass panels are retained in place by a standard pressure plate and cap keeping the overall aesthetic look of the façade.
