The Rockwool FirePro range

offers a large choice of fire protection and fire-stopping solutions. Rockwool has unrivalled experience in fire protection and offers solutions with exceptional thermal, acoustic and environmental benefits. This extensive range of passive fire protection solutions is designed for use in general building, industrial, marine & offshore applications.

All products in the range have been independently assessed for their particular use and where appropriate, are supported by third party approval from accredited bodies, such as the Loss Prevention Council, Lloyds Register of Shipping and Metronet.

Fire Barrier Systems

Rockwool Fire Barrier systems offer labour-saving solutions to prevent fire and smoke spread within roof and ceiling voids for all general conditions encountered on site.

The vertically hung Fire Barriers are capable of achieving both integrity and insulation protection periods from 15 to 120 minutes and the friction fitted Fire Barrier Slab can also provide 60 minutes integrity and insulation. It is Rockwool’s essential insulation performance that limits the heat transfer through the barriers, preventing ignition of combustible materials in adjacent areas.

The new patent applied for, support system (application no. 0329817.1) offers a quick, cost effective installation method for the Fire Barriers for periods up to 60 minutes. This focus on ease of construction and installation has the added benefit of reducing the risks of installation error.120 minute systems are also available using the traditional support methods.

Extended drops are easily catered for, with the system capable of maintaining its performance in void heights up to 10.5 metres.

Rockwool Fire Barrier systems have been developed to inhibit the spread of flames, heat and smoke through concealed spaces in buildings and improve sound reduction. When used in conjonction with suspended or plasterboard ceilings, the flanking sound can be reduced by up to 50 dB. The actual reduction will depend on the number of layers used.

Fire Barrier installation

Fire Stopping - Large voids - ½ hour Cavity Barrier

Rockwool Fire Barrier solution is applied as a hanging curtain. The barrier is continuously supported and secured to the soffit at its head. At the base it is preferable in a cavity barrier situation to wire the barrier to the ceiling grid although it is acceptable to let it drape freely, turned back across the ceiling.

If the Fire Barrier is to form a continuation within a void of a fire resistant wall/partition, it is essential to fix the barrier to the wall/partition head to maintain integrity.

Fixing to timber

Fire Barrier can be applied to a timber truss construction as a half hour cavity barrier within the roof space to satisfy the requirements of Building Regulation B3 – (4).

If the truss is constructed from a minimum timber size of 35 to 49mm thick, both sides of all truss members/bracing require protection from fire in order to minimise charring. Strips of 50mm Fire Barrier is used on the reverse side of the truss for this purpose.

Alternatively, a second layer of Fire Barrier may be applied to provide 1 hour fire rating.

Nail plate fixings may fail prematurely in fire unless protected .

For fixing to timber, the Rockwool clamping plate is used, compressing the barrier to the timber, fixed at 450mm centres using No. 10 woodscrews.

Rockwool angle support clamping plate system

To use the patented Rockwool angle support system, bend tongues out to 90° and impale barrier onto them. The slotted clamping plate is then fitted by pushing the tongues through the slots and these are then bent over the face of the clamping plate completing the process.

Fixing to concrete soffits

For fixing to concrete soffits, the pre-punched angle support is fixed using Hilti DBZ or Ejot ECL 35 hammer set anchors at max. 750mm centres.

Fixing to steel purlins

For fixing to steel purlins, use Hilti SMD 02Z (5.5 × 70mm) self-tapping screws at max. 450mm centres.

60-30 Fire Barrier

If 30 minutes insulation is required, use 1 layer of 60mm foil faced fire barrier with 100mm vertical over lapped joints. The barrier is otherwise fixed as previously shown for timber construction.

Fire Stopping - Large voids - One hour Cavity Barrier

Rockwool Fire Barrier solution is applied as a hanging curtain. The barrier is continuously supported and secured to the soffit at its head. At the base it is essential to fix the barrier to the wall/partition head to maintain integrity.

The Rockwool support angle has tongues that are pushed out from opposite sides at 300mm max. centres.

Two 50mm Rockwool Fire Barriers with staggered joints are then impaled on the tongues on both sides and clamped using the Rockwool clamping plates. The tongues are finally bent over the clamping plates, completing the system.

Note that wire reinforced sides should be placed outwards.

Fixing to timber

When a one hour Fire Barrier is supported on structural timber (for example a trussed rafter), and the thickness of timber is 35–49mm, one layer of 60mm Rockwool Fire Barrier must be placed on each side of the timber. Where timber thickness is 50mm or greater, 2 layers of 50mm Fire Barrier are sufficient.

Fixing to concrete soffits

For fixing to concrete soffits, the pre-punched angle support is fixed using Hilti DBZ or Ejot ECL 35 hammer set anchors at max. 750mm centres.
