Product Description

“FReD 60 Minute Bulkhead” is a fire resisting division consisting of Ayrlite 3007 composite panels and stainless steel supporting structure, mounted so that a minimum 150 mm air gap is maintained between the back (non-fire side) of the panels and the structural aluminium bulkhead, and a minimum 50 mm air gap is maintained between the back (non-fire side) of the panels and the aluminium stiffeners.
Aluminium bulkhead
Aluminium bulkhead shall consist of 6 mm shell plate with stiffeners of 100 mm x 75 mm x 9 mm
every 600 mm. Equivalent stiffness will be accepted.

fibre faces and aluminium foil backing. A layer of 7 mm thick intumescent material (type: see PS 3007-D
item 4.3), and a layer of 0.25 thick veneer (type: see PS 3007-D item 4.4). The panels have maximum
dimensions 1184 mm x 2384 mm (W x L). Total thickness of composite panel is 20 mm.
Stainless steel supporting structure
The supporting structure with panels is fixed to the structural aluminium bulkhead using stainless steel
standoff brackets. An airgap of minimum 150 mm is maintained between the structural aluminium
bulkhead and the reverse (non fire side) of the panels and minimum 50 mm air gap is maintained
between the back (non-fire side) of the panels and the aluminium stiffeners. The standoff brackets are to
be at maximum 1200 mm spacing in panel width direction and maximum 1500 mm in panel length
direction.
Inspection hatch
The bulkhead can be fitted with an inspection hatch with maximum clear opening of 760 x 760 mm (W x
H), with two hinges and a three way locking system. The hatch to be installed in the middle of the Ayrlite
3007 composite panel or at least 120 mm away from the panel joints. The hatch leaf, of dimensions 840
mm x 840 mm x 45 mm (W x Hx D), is composed of 0.7 mm thick stainless steel hatch door surround
with layer of intumescent seal fitted on the hatch door surround at the interface to hatch frame. A 42
mm thick Ayrlite 3007 panel is installed inside into the hatch door surround. The hatch frame is
