Firestoppa IZ is a stainless steel reinforced E Glass fibre base fabric coated both sides with a heat radiation reducing, ‘insulating zone’ graphite silicone coating. The specially formulated coating on the IZ fabric makes the final product heavy duty.
The FireStoppa IZ is an insulating zone fire retardant fabric and when exposed to temperatures above 160ºC the coating system will form a rapid expanding carbonaceous char of organic matter, suppress smoke release, dilute combustion gases with liberated water vapours and consequently provide a thermally insulating barrier. It is an industry standard Stainless Steel Reinforced Fire and Smoke Fabric.
FireStoppa IZ is a heavy duty fabric that is capable of stopping fire for over 2 hours. The base cloth is a stainless steel wire reinforced satin weave glass fibre fabric which is then coated both sides with a intumescent graphite silicone coating.
The FireStoppa IZ fire retardant fabric is suitable for full fire protection and stopping as well as smoke, with extended performance for higher temperatures, strength and flex performance.
The IZ fabric satisfies and is specifically tested and compliant to BSI PAS 121 2007.
FireStoppa IZ has achieved the following radiation levels monitored as part of a test 1 metre away from the fabric:
20mins – 4.80 kW/m2
30mins – 5.84 kW/m2
60mins – 9.29 kW/m2
90mins – 13.00 kW/m2
107mins – 15.7 kW/m2
The base fabric of FireStoppa IZ is an 8 shaft satin weave.
FireStoppa IZ is suitable for internal use.
This fabric can be used externally as it is coated with a high quality grade silicone elastomer. Silicones are known in the industry for their outstanding resistance to weathering and environmental influences, such as exposure to high and low temperatures, UV Light, Humidity, Radiation and Ozone. There is little change to the properties of silicone when exposed to the elements.
FireStoppa IZ has not been specifically tested by us for external use, however, we do use high end, long established automotive and aviation silicones grades, which have been tested by suppliers and their customers independently. All generic properties of silicone elastomer apply.
Fire Fabrics Direct can offer bespoke manufacturing with our product range of fire and smoke fabrics. We have been asked to make large static smoke or fire barriers for loft spaces that require two widths of fabric being stitched together or a number of small products such as soldering mats and other plumbing supplies.
