Core

Panel cores are self-extinguishing grade expanded polystyrene Class SL, manufactured to Australian standards. Steel skins are bonded to the core under pressure using a two-part thermosetting polyurethane adhesive.

EPS Panel cores are also available with a thermal link finger joint on vertical panel joints for freezers and CA storage applications. This finger joint is used for panels between 150 and 200mm thickness; these panels are called Thermalink ®.

Other specialised cores are also available on request.

‍

Skins

Sheet thickness can range from 0.40mm to 0.60mm for either surface skin. Panel skins are available with a choice of steel:

Colorbond® Permagard™ steel, incorporating Microban® antibacterial technology in its coating to provide durable, food-safe performance that will not wash off. This steel is available in Permagard™ White only.
Colorbond® standard grade steel comes in a wide range of designer colours.
There are other skin materials available on request,including Stainless Steel, Aluminium and Printech™ printed steel.

‍

Colour

The many colours available in Colorbond® range from traditional to modern. For Prestige Applications there is Colorbond® Metallic steel. Generally, the lighter colours are preferred for external use, because they reflect solar radiation. The various surfaces and colour choice can influence the price per square metre.
‍

Dimensions

Width: 1200mm as a modular standard.
Thickness: 38mm and 50 to 300mm in multiples of 25mm.
As required, determined by handling, design and transportation.

Section Properties

Section properties and mass for unit (1000mm) width of panel, together with the recommended maximum design skin stresses have been determined for panels of varying panel thickness and these are shown below.

Notes

The tabulated design loads are factored maximum design loads. (In the assessment of the design loads, the designer should take into account the self weight of the Econotilt panel).
Compliance with these recommendations will ensure that deflections do not exceed span/90. Where more severe deflection restrictions are required, specific testing of deflection characteristics is recommended for the various span/thickness combinations.
A minimum design load of 0.68 kN/m2 is recommended for general applications. Design loads below the lightly shaded area satisfy Serviceability Limits on deflections. Circumstances may require different design loading.
Where panels are continuous across a support, it is recommended that stress cuts be made across the inside (or cold side) steel skin adjacent to the supports to prevent buckling of the outer (warm side) skin at the support. Fixings should be provided on both sides of the stress cut.

‍

Polystyrene Core Butt Joints

The butt joints between the ends of the polystyrene core material have been made by way of finger jointing providing a mechanical bond across the end faces of the core material. The finger joints of the polystyrene core material occur at every point.

Profiles

Available with a surface finish or low profile of 0.75mm depth to either surface: 100mm Rib profile, 50mm Mesa Rib and Silkline. The Austral Slip-joint® is incorporated into the edges of both surface skins for easy installation.

Core

Panel Cores are lightweight, fire-resistant composite insulation material manufactured to Australian standards. XFlam is both recyclable in itself and is capable of absorbing recycled foams such as EPS, PUR and PIR. Steel skins are bonded to the core under pressure.
