Insulated Fire Sleeves are a combination of Rockwool stone wool and graphite intumescent. Supplied with a factory applied reinforced aluminium foil facing.

When thermally insulated plastic pipes pass through fire resisting walls and floors, the insulation is normally removed at the point of penetration to enable standard pipe collars and wraps to close the resulting void when the plastic softens and melts due to the effects of a fire. However, the removal of this insulation may result in the formation of condensation on cold pipework or heat loss from hot pipes. Insulated Fire Sleeves avoid this problem by providing both fire stopping and thermal insulation in a single product.

Insulated Fire Sleeves are intended for use on copper, steel and most types of plastic pipes, trunking and conduits to provide up to 4 hours* fire resistance.

Features & Benefits

• Should be installed to the same thickness as the pipe insulation (min 25mm thick). For uninsulated pipes, a thickness of 25mm is required to maintain the fire resistance of the wall or floor
• Quick, simple and accurate installation
• Maintains pipe insulation at penetration points
• Supplied with integral vapour barrier
• No mastic or ancillaries required
• Can provide thermal and acoustic insulation
• Tested with a range of pipe materials which penetrate walls and floors, achieving up to 4 hours* fire resistance
• CE marked to EAD 350454-00-1104
• When tested onto copper pipes within a lightweight wall construction, Insulated Fire Sleeves achieved Rw (C;Ctr) = 49 (-2;-8) dB

*Subject to application.

Installation

Please see Product Data Sheet and Installation Guide for detailed installation instructions.

Insulated Fire Sleeves are supplied 300mm long and are simply cut to the desired length and as a minimum, be cut flush with both faces of the wall/floor. When used in conjunction with PVC services or Rockwool Ablative Coated Batts, they are required to extend beyond the face of the wall/floor. 

Supporting construction designation:

• Floors: Cast concrete between 1100 and 2400kg/m³ density
• M=Masonry between 600 and 1500kg/ m³ density
• PB= Plasterboard clad steel or timber stud partitions with fire resistance at least the same as the Fire Sleeve performance
• CB= ROCKWOOL 50 or 60mm thick Ablative Coated Batt

Insulated Fire Sleeves should project by at least 25mm beyond the visible face of each Coated Batt. There must be at least 50mm width of Coated Batt between any fire sleeve and the edge of the aperture and also between individual Fire Sleeves.

If gaps exceed 15mm around the aperture and the sleeve, the gap should be filled with Rockwool Acoustic Intumescent or Firepro Firestop Compound. If gaps exceed 8mm between the service and the sleeve, these can be infilled, locally where the service penetrates the aperture, with the Acoustic Intumescent Sealant.

The installed length of any Insulated Fire Sleeve shall be at least 60mm.

Maintenance

To maintain thermal efficiency, the Insulated Fire Sleeves should tightly abut any existing pipe insulation and where this is foil faced, all joints must be sealed with self-adhesive class O foil tape.

Other Install Info e.g. Ancillaries

No specialist tools or ancillary materials are required for the fitting of Insulated Fire Sleeves. Insulated Fire Sleeves can accommodate irregularities in the division opening and the pipe O.D. of up to 15mm. Multiple pipe penetrations can be accommodated in conjunction with Ablative Coated Batts. A minimum thickness of 25mm is required for uninsulated pipes. Thicknesses of 25 to 100mm available to match insulation already installed on pipework. Manufactured to fit pipe diameters of 15 to 169mm.
