PolarTec is a  dry vertical jointed system with deflection head.  The system is double glazed and provides outstanding performance requirements.  It has been independently tested to provide 30 minutes integrity and insulation for fire resistance; 48dB (Rw) for sound performance and 'Severe' strength to BS5234 for structure.  In additional tests it achieved the necessary standards to meet crowd pressure requirements, so important in public areas such as schools. The deflection head facilitates relocatability, if required.
