Fire Curtains

Click for more info
Fire curtains prevent the spread of fire and smoke through voids and also provide compartmentation between different areas within buildings.
JNR can install and maintain both lightweight flexible fire curtains or insulating fire barrier curtains to provide up to 120 minutes fire protection within both occupied and unoccupied facilities.  This includes lofts, ceiling voids and risers and the fire curtains ensure no fire or smoke can spread from one compartment to the next.

With roof voids we carry out surveys to highlight what is required to make sure buildings are in accordance with building regulations and to ensure that fire compartment walls are continued above the ceiling and into the roof void.  If required we can also provide and install fire-rated access hatches, walkways and handrails for the roof space as well as improving its insulation.

All fire curtains installed by JNR are fully tested, certified and comply with the relevant BS or EN standards.

Penetration Sealing

Penetration seal systems for fire stopping are a highly effective form of passive fire protection (PFP). They are used to thoroughly compartmentalise a building to restrict the spread of fire. Using fire sealing products to either fill imperfections and gaps between fire-resistant areas. Or, to create a fire-resistant surface thus creating a penetration seal system. These systems will protect your construction’s surfaces; cables; ventilation; and piping by using technologies including rockwool; graphite; and intumescent acrylic.
