PU28 Fire Barrier 4 Hour is versatile fire barrier for use in smoke and fire control systems.
PU28 Fire Barrier is a stainless steel wire reinforced glass fabric with a specially formulated intumescent fire retardant silicone elastomer. This is designed for applications including removable insulation covers, smoke and fire curtains, blinds, cavity wall fire barriers and other types of smoke and fire control systems. The material does not generate toxic emissions, and has good resistance to hydrolysis whilst still having a flexible handle. When the PU28 4 Hour is exposed to temperatures in excess of 140° C the coating system will form an expanding intumescent char that provides a thermally insulating barrier.
Please note: This product is designed to contain the passage of smoke and flames. It will not insulate against the heat of a fire. If forming a cavity barrier or forming a fire barrier, please ensure that the product you use has the required insulation value. This note is for advisory purposes only and does not warrant any design characteristics.
Please note: We would always recommend that you seek advice from your local Building Control Department or Fire Officer regarding the type of fire protection they require. This may involve the necessary level of protection and integrity and insulation values. We have specialists that can walk you through your project as every application varies. However, it remains down to the end user to determine suitability.
