System components and accessories

The Permaflor system includes a wide range of components and accessories to help achieve the most flexible and efficient floor designs, allowing HVAC systems, power supply, data cabling and other building services to be routed in the floor void.

This facilitates future changes to layout and occupancy, provides relatively easy access for maintenance and allows installation of additional or upgraded services. Using the floor void for HVAC services instead of overhead can significantly reduce slab-to-slab heights in multi-floor buildings.

Pedestals

A choice of four adjustable-height pedestals is available conforming to the performance requirements of both BSEN and PSA specifications and giving void height options from 40mm - 2000mm. Pedestals may be adhesively or mechanically fixed to the slab. Locating lugs on the head ensure correct panel seating, with the option of screw-fixing for additional rigidity.

Pedestal	Grade	Stud Size	Base Size	Void Range
S1	BSEN & PSA Medium	M16	114mm Ø	60-390mm
S2	PSA Medium	M16	90mm Ø	60-295mm
S3	PSA Medium	M20	114mm Ø	60-700mm
X1	PSA Medium - Heavy	M35	100 x 100mm	75-2000mm

Pedestals - type S (voids 60 - 700mm)

For standard floor heights: die-cast aluminium head with eight integral panel locators cast in; threaded steel column onto die-cast base with reinforcing webs pre-drilled for optional mechanical or adhesive fixing to substrate.

Electro-plated steel stud supplied cut to length as specified, with levelling nut giving 40mm vertical adjustment on-site. Earthing studs may be pre-fitted; optional PVC sleeve available; optional electrocondutive anti-vibration head gasket.

Can be used with / without stringers.

Stringers

Where additional lateral stability is required or where floor heights exceed 600mm, stringers may be attached to the pedestals. Stringers will improve lateral stability and rigidity but will not affect load bearing performance.

Oversized / undersized panels

To minimise cutting on site and facilitate panel fitting around perimeters, special sized panels can be supplied to order.

Bridging beams

Where obstructions in the void or substrate prevent pedestal positioning at the corner of the panel, bridging beams can be used to provide continuous support to the panel and span the obstruction.

Electrical outlets

Power supply for individual work stations can be routed to cable outlet grommets mounted within designated access panels. These can be supplied as either fully assembled panels or factory-cut for on-site installation by the M&E contractor.

Ventilation panels

A range of ventilation panels for underfloor HVAC systems are available including perforated or bar-grilled formats.

Cavity barriers

Fire, acoustic and air plenum barriers can be supplied for installation as required.

Ramps and steps

For disabled access or to facilitate changes in height between adjacent floors steps or ramps can be manufactured to meet specified gradient or height changes.
