Remove section of mineral wool from CP 674 back to corner leaving intumescent strip. Coat back of intumescent facing strip with CP 606/CFS-S ACR. Take section of CP 674 barrier for other wall face and position end to the intumescent strip from previous step. Fix barrier to substrate Butt barriers together Ensure barrier alignment/flush surfaces Butt Joints: Cavity Barriers must tightly abut one another Can be installed NonVentilated first and then Ventilated, or vice-versa Space Constraints: Brackets installed below the barrier need to be protected Where access constraints mean brackets cannot be fixed above the cavity barrier, the brackets may be fixed beneath the barrier, with 50 mm CP 670 (coated board) used to protect brackets. 10/21 PP Notice: The product's foil cover is used for branding purposes only.

Therefore if assessed against the integrity and insulation (max temperature rise only) performance criteria of BS 476: Part 20: 1987, from this point, then: 111 mins integrity and 88 mins insulation (specimen C); and 105 mins integrity and 83 mins insulation (specimen D) were recorded.

Reg No. 11371436 10/21 7 WF Test Report Summary WF No. 412510 Page 2 of 2 Specimen B Table 3 Brief Details of Specimens Construction Description Specimen B comprised of a foil faced stone wool fibre cavity barrier referenced `Hilti CP 674V 288' which had a stated density of 120 kg/m3. The barrier had overall dimensions of 1300 mm long, 288 mm wide and 75 mm thick. The barrier was installed with a butt joint which was taped with aluminium foil tape at 300 mm from one end of the barrier. The barrier incorporated a 25 mm wide by 1.5 mm thick graphite based intumescent strip which was bonded to the leading edge. The barrier was fixed to the supporting construction using four steel hangers. Above and below the joint was two vertical section of `Hilti CP 674NV 307-313' cavity barrier which incorporated a 30 mm x 30 mm section of intumescent foam strip down the length of the sections. The specimen also included a layer of 150 mm thick `RW3' stone wool insulation above and below the barrier with a stated density of 60kg/m3. The insulation was fixed to one face of the supporting construction using metal insulation fixings. The barrier was installed to provide a 25 mm air gap. C Specimen C comprised of a foil faced stone wool fibre cavity barrier referenced `Hilti CP 674V 241-288' which had a stated density of 120 kg/m3. The barrier had overall dimensions of 1300 mm long, 288 mm wide and 75 mm thick. The barrier was installed in two sections. The barrier incorporated a 25 mm wide by 1.5 mm thick graphite based intumescent strip which was bonded to the leading edge. The barrier was fixed to the supporting construction using four steel hangers. Between the two sections of barrier was a penetrating `Hilti Eurofox MFT-S2S TT rail & U bracket'. The bracket was fixed to the supporting construction using 4 No. Hilti HRD-H anchors. The rail was fixed to the bracket using 8 No. S-AD 01SS screws. The barrier was installed around the rail and bracket and sealed with Hilti Mastic CP606. The intumescent strip of the barrier was cut and overlapped around the front of the rail to provide a continuous length of intumescent across the full length of the barrier. 60kg/m3 mineral wool was installed in the cavity between the bracket and rail. The cavity within the rail was sealed with Hilti CFS F FX expanding firestop at the exposed face of the barrier. The specimen also included a layer of 150 mm thick `RW3' stone wool insulation above and below the barrier with a stated density of 60kg/m3. The insulation was fixed to one face of the supporting construction using metal insulation fixings. The barrier was installed to provide a 25 mm air gap.
