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
Certificate
ETA-21/0461: Jan 3, 2025
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.
