The fireproof wrap of the System NBR-plus used for the fire sealing of various pipelines in a wall cross-section.
Pipe penetration seal

System NBR-plus

The System NBR-plus is a firestop pipe penetration sealing system made of a separable fireproof wrap for non-combustible pipes and pipelines with FEF insulation and glass wool insulation as well as HVAC split lines. Fire-resistant up to max. 120 minutes.

Areas of application

Sealing of pipe penetrations in:

  • Plasterboard walls (≥ 100 mm)
  • Solid walls (≥ 100 mm)
  • Solid floors (≥ 150 mm)
  • Timber construction (CLT walls and CLT floors)

Highlights

  • Sealing of insulated non-combustible pipes with outer diameters up to 323.9 mm and HVAC split lines
  • Single-product solution
  • Low material requirements in walls (separation of the wrap) and floors (only installed on the underside)
  • Annular gap seal with various materials (e.g. mortar or plaster)
  • Sealing of all customary elastomeric foam insulations (FEF)

Fire resistance class

Max. EI 120 acc. to EN 13501-2

Features

  • Weather-resistant to moisture, freeze-thaw cycles, and UV radiation (use category X)
  • Intumescent inner coating and resistant outer glass fabric
  • Can be coated over
  • Flexible material for easy application and wrapping of pipelines

Installation video: System NBR-plus

The System NBR-plus fire protection tape offers an effective solution for sealing off insulated non-combustible pipes up to an external diameter of 323.9 mm and air conditioning split ducts. Due to the division of the tape, only a small amount of material is required to install the seal. The NBR-plus system fulfils the requirements of the fire resistance class up to EI 120 in accordance with EN 1350-2.
