Flatboard

Superflex is a smooth surfaced asbestos-free, Flatboardcellulose fibre reinforced cement building board. Autoclaved, it is tough and flexible, and is the ideal choice for many general building purposes, both internally and externally.

Superflex won the FMM award for "Product Excellence" when it was launched in 1985. Unsurpassed for economy and ease of working, Superflex is as durable as it is adaptable.

Available in a range of stock lengths, widths and thicknesses, it is ideal as cladding for walls, ceilings, porches, gable ends, partitions and permanent formowork.

A versatile board, Superflex will not burn, rot, split or swell and is not affected by termites, insects or vermin under normal conditions. It can be cut, drilled, nailed and worked in similar fashion to timber and chipboard, but offers a much longer life performance. Flatboard Fixing Instructions.

General Product Information

Basic Composition:

 Portland cement, refined sand, Basic Compositioncellulose fibre and water.

Durability:
It is autoclaved, resistant to water penetration, will not  rot and is unaffacted by termites,  insects and vermin.

For applications within normal specifications, the life span of the product is limited only by the durability of the supporting  structure and the materials used in  fixing.

Handling and Storage

Boards should always be stacked flat on a smooth level surface. Edges and coirners should be protected from chipping.

Timber blocks may be used as supporting surface provided a smooth flat surface is ensured as shown in diagram.

To ensure optimum performance store sheets undercover and keep dry prior to fixing. If the sheets should become wet, allow to dry thoroughly before fixing is commenced.

Painting

For excellent results, Superflex board may be painted with water based acrylic paints.

Painting

No additional primers or sealres are required.

In all cases reference should be made to the paint maufacturer's instructions.

Mass
The mass of Superflex 6.0mm (based on Equilibrium Moisture Content) is approx. 8.5kg/m2

Framing
Superflex boards are suitable for fixing to timber or metal framing.

Boards fixed to metal framing should be of minimum 6.0mm thickness.

Framing should be constructed in accordance with local building regulations and accepable building practice. Studs should be spaced at 605mm centres.

The maximum distance between noggings is 1220mm.


Metal Frames
Metal framing members should be fabricated from light gauge sheet metal 1.2 or 1.6mm thick.

Superflex board must be fixed directly to drawn steel or hot rolled steel sections which first be lined with timber battens of suitable thickness or light gauge steel framing members.

Insulation
Where foil insulations is used as a climate control and moisture barrier, it should always be fixed to the outer side of the stud in the framework.

Fasteners
Nails (for fixing to timber frames)
Galvanised Wire Nails

25mm long for hardwood
30mm long for softwood.
