Firestoppa 4BOS is a stainless steel reinforced E Glass fibre base fabric and is coated both sides with a carbon black pigmented fire retardant silicone elastomer for black out and light reduction.
FireStoppa 4BOS fire retardant fabric is a black out Fire and Smoke Fabric and remains integral for 4 hours at 1000oC.
Designed for an application such as fire curtain barrier assemblies with an additional black-out feature, the intended fabric was for high strength, increased flexibility at a wide temperature range, low toxicity, resistance to abrasion and possible exposure to water and water vapours.
The base fabric of FireStoppa 4BOS is a panama weave.
FireStoppa 4BOS 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 4BOS 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.
