Our ISO-TOP WINFRAMER “TYPE 1” E30 IN FRONT OF WALL INSTALLATION SYSTEM was specially designed for use in fire protection facades. The intumescent components of the new PURATHERM E30 material create an expansion effect when exposed to significant heat levels. The system angles and system boards are therefore suitable for applications where there are special fire protection requirements for load transfer from windows and balcony and patio doors. They also provide an optimum base for sealing window connection joints.
