This horizontal cladding system has been designed for use as a non-load bearing external fire wall situated at least 1 metre away from a relevant boundary. Secured outside rail the construction incorporates Rockwool insulation and satisfies the criteria for 4 hours integrity (15 or 30 mins insulation) when assessed to comply with BS476 Part 22: 1987 in relation to internal fire exposure and installed in accordance with Approved Document B (Fire Spread) Building Regulations 2000.

HRF 35 - Specification - CONSTRUCTION NOTES

Structural Frame
To be protected using suitable materials providing a fire resistance period equal to the cladding system. Support cladding from suitable structural element, e.g: Firerated eaves beam.

Cladding Rails
Supplied in shorter lengths than normal with slotted holes to facilitate expansion. Install in single span condition using 16mm diameter steel bolts with steel and plastic washers. RaiL centres for vertical lining not to exceed 2m.

Internal Lining
To meet 30 minute insulation period, stitch lining panel side laps at 300mm centres using steel rivets.
e.g:TSPD 44 BS or equivalent.

Vapour Control Layer
Lining Panel - Seal side and end laps.

Insulation
Friction fit between lining panel and back face of spacer bar.

External Cladding
Install horizontally as per normal recommendations.

Base Support Bracket
Secure to cladding via spacer bracket fasteners. Stitch to spacer bar using 2No. nonwashered 5.5mm diameter steel self drilling screws.
