Field of the Invention
The invention relates to a wall cladding system and, more particularly, but not exclusively, to a wall cladding system in the form of an External Insulation Fagade System (EIFS) having a render bead.
Background of the Invention
It is known to provide a wall cladding system in the form of an External Insulation Facade System (EIFS) such as the facade system marketed by the applicant under the Exsulite product name.
The applicant has identified problems with existing External Insulation Fagade Systems. In particular, the applicant has identified that there are problems in External Angle Beads and Starter Channels manufactured from differing materials other than EIFS expanding and contracting in weather conditions. There has been a decline in the number of qualified plasterers and a drop in the skill level of many tradespeople servicing the building industry. The applicant has determined that it would be advantageous to provide a system which (eliminates the need to use differing materials that have differing expansion and contraction rates to EIFS) and which assists the applicator in correctly applying and terminating render on foam cladding, both in achieving a solid termination point and in achieving the correct film thickness.
Examples of the invention seek to provide an improved wall cladding system which overcomes or at least alleviates disadvantages associated with existing wall cladding systems.

Detailed Description
The applicant is a pioneer in the use of External Insulation Fagade Systems (EIFS), designing and installing coating systems specifically for wall applications. EIFS walling systems have been used in Europe for many years. In recent years, the use of lightweight cladding systems, as alternate solutions in the building and constructions industry has grown rapidly but proper system design and installation has not been considered.
The Building Code of Australia (BCA) (or National Construction Code (NCC)) requires appropriate design and installation controls to qualify any alternate solution and ultimate success requires a total system approach integrating design, componentry, installation and performance requirements.
The Exsulite facade system by Dulux AcraTex protects specifiers, surveyors, builders and their clients from the risks of mixed componentry being used with uncontrolled installation. Exsulite facade system by Dulux AcraTex offers a single supply source for the total lightweight facade system - from wall wrap to the weatherproofing coating. The Exsulite facade system is a lightweight exterior walling system that provides both weatherproofing and insulation of the building envelope and helps to eliminate thermal bridging that can occur through the wall frame.
The Exsulite facade system is designed as a total integrated non-load bearing lightweight facade system to deliver a weatherproof external building envelope with a self draining cavity for moisture management whilst providing high thermal performance (R value). The Exsulite facade system is certified as a total integrated facade system for use as either a cavity or non-cavity system.
The Exsulite facade system comprises of an Exsulite breathable wall wrap, flashing tape to all openings and penetrations, Exsulite EPS Panel or Exsulite Pre-Coated Composite Panel, Exsulite starter piece/cavity closer with weep holes, Exsulite fixing components, EPS "H" Grade wall cavity spacers where a cavity system is selected, Exsulite Matrix Basecoat with alkali resistant mesh, Exsulite Texture and Exsulite Membrane weatherproof protective coating or an approved Dulux AcraTex texture and AcraTex membrane topcoat system designed and supplied by Dulux AcraTex and installed by a Dulux AcraTex Exsulite trained and registered installer.
With reference to Figures 1 to 20 of the drawings, there is shown a wall cladding system in accordance with an example of the present invention. Advantageously, the wall cladding system uses an elevated bead on the edge of the cladding which is specifically designed to (eliminate the need to use differing materials that have differing expansion and contraction rates to EIFS) assist the applicator in applying and terminating render, both in achieving a solid termination point and in achieving a correct film thickness of the render. The elevated bead may be formed integrally as part of a polystyrene body of the cladding panel or integrally as part of a coating of render which is applied to the body of the cladding panel. By making the bead integral in this way, this ensures that the bead expands and contracts thermally in environmental conditions, evenly with the rest of the cladding panel such that the bead and the rendering remain attached to the cladding panel, reducing the likelihood of undesirable cracking and separation of the render from the panel (and reducing installation and coatings time and skill required).
More specifically, with reference to Figures 1 to 5 of the drawings, there is provided a wall cladding system 10 including a cladding panel 12. The cladding panel 12 has a body 14 formed from a first material, and the cladding panel 12 includes a bead 16 for facilitating application of a coating to the cladding panel 12. With reference to Figure 1, the body 14 is formed as a unitary part of polystyrene material 18 and, preferably, expanded polystyrene material (EPS). The bead 16 is a render bead adapted for facilitating application of a coating of render to the cladding panel 12. The render bead 16 is formed as part of the cladding panel 12.
As shown clearly in the side perspective view of Figure 1, the cladding panel 12 includes a coating of render 20 applied to an external surface 22 of the body 14 and the render bead 16 is formed of render as part of the coating of render 20. This promotes even thermal expansion of the render bead 16 with the coating of render 20 to avoid separation of the render bead 16 from the body 14. The material forming the coating of render 20 may be in the form of a polymer render. Figure 2 shows a front view of the cladding panel 12 which shows the face of the external surface 22. Although the coating of render 20 is shown as having a thicker portion near the bead 16, in other examples the thickness of the coating 20 adjacent the bead 16 may extend over the entire external surface 22 of the cladding panel 12.
Figures 3 to 5 show a cladding panel 12 in accordance with another example of the present invention in which the cross-sectional profile of the cladding panel 12 is rectangular rather than having the angled edge 24 and stepped rear surface 26 as in the example shown in Figures 1 and 2. The cladding panel 12 of Figures 3 to 5 visibly shows a reinforcing mesh 28 which is embedded in the coating of render 20.
As an alternative to the examples shown in Figures 1 to 5, the bead 16 may be formed as an integrally formed part of the body 14 made from the polystyrene material 18. Either way, the render bead 16 is arranged to regulate an even layer of a render material to be applied on top of the coating of render 20. In preferred examples of the invention, the render bead 16 may have a height within the range of 2 to 5mm. In a preferred form, the render bead 16 may have a height of 2.5mm.
The coating for render 20 may be weatherproof and may facilitate adhesion of the layer of render material to the cladding panel 12.
The cladding panel 12 has a length (the length of the bead 16 and the corresponding face of the cladding panel 12) and a constant cross-sectional profile along that length from one end of the cladding panel 12 to an opposite end of the cladding panel 12. The cladding panel 12 is adapted to be cut to size, as may be facilitated by the polystyrene material of the body 14.
The applicant has determined that it would be beneficial for different profiles to be available for different purposes. For example, with reference to Figures 6 to 12 of the drawings, there is shown a set of cladding panels 12 wherein each of the cladding panels is a cladding panel generally similar to the panels 12 shown in Figures 1 to 5, only with a plurality of cladding panel models, each model having a different profile to suit a different application/installation type. Each of Figures 6 to 12 shows a profile of a different cladding panel model which is suitable for a particular application/installation type. Each of the cladding panel models shown in Figures 6 to 12 has a body 14, a bead 16 and a coating of render 20. More specifically, Figure 6 shows a pre-coated cavity square starter block, Figure 7 shows a pre-coated cavity reveal/slab starter block, Figure 8 shows a non cavity pre-coated slab rebate starter block, Figure 9 shows a pre-coated angled non-cavity starter block, Figure 10 shows a pre-coated sill block, Figure 11 shows a pre-coated slab rebate starter block, and Figure 12 shows a pre-coated cavity angled starter block.
Figures 13 to 20 show examples of installations of cladding panels 12 of the present invention. In particular, Figure 13 shows installation of the cladding panel 12 of Figure 12 in relation to a metal deck roof, Figure 14 shows installation of the cladding panel 12 of Figure 12 in relation to roof tiles, Figure 15 shows installation of the cladding panel 12 of Figure 7 showing slab rebate detail, Figure 16 shows installation of the cladding panel 12 of Figure 6 showing typical garage bulkhead detail, Figure 17 shows installation of the cladding panel 12 of Figure 6 showing typical parapet-balcony bulkhead detail, Figure 18 shows installation of the cladding panel 12 of Figure 7 as well as the cladding panel 12 of Figure 10 in relation to a typical framed window head and sill, Figure 18 shows installation of the cladding panel 12 of Figure 10 in relation to a metal deck roof, Figure 19 shows installation of the cladding panel 12 of Figure 9 in relation to a typical non-cavity system, and Figure 20 shows installation of the cladding panel 12 of Figure 11 showing a typical slab starter block and slab rebate detail. Installation may be, for example, in a parapet wall construction to box cutter arrangement, in a window arrangement, or in a meter box penetration arrangement. The cladding panels 12 of the present invention may be adapted to be fixed to (timber or steel) framing by virtue of washers and screws.
