Qsystem - VGF35

4 Hour Fire Rated VerticalWall Cladding System (Glass Fibre) - 0.35 ‘U’Value

This 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
glass fibre insulation and satisfies the criteria for 4 hours integrity (15 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..

VRF 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: Fire rated 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 cladding span not to exceed 2m
.
Internal Lining
To meet 15 minute insulation period, stitch lining panel side laps at 450mm centres using steel rivets.
e.g:TSPD 44 BS or equivalent.

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

Insulation
Compress between lining panel and front face of spacer bar.
