Application

Used to seal combustible pipes as they pass through fire compartment walls and floors. When exposed to fire, the intumescent lining within the metal sleeve expands and fills the space left by the heat softened pipe thus reinstating the fire compartment line. The product is suitable for retrofit or maybe installed prior to service installation. When used as a multibox or cable closer, foam smoke seals should be requested.

Description

A steel encased closer device for combustible pipes of up to 200 mm. Available in various lengths, it is the perfect solution for angled pipes. FP160 provides service integrity of up to four hours, dependent on substrate. It may be used directly in solid or flexible substrates, or within FB750 coated batts. Additional clips may be required in floors slabs.

Features and benefits:

  • CE marked.
  • Ultra-slim body design ensures easy installation in awkward situations - reduces time on site.
  • Less obtrusive than externally fitted fire collars - better aesthetics.
  • Tested to two hours' integrity and insulation within walls and four hours integrity and insulation when used within FR230 fire resistant compound floor seals.
