The Eggers OSB/3 board also has British Board of Agrément (BBA) certification It is also noted that the OSB bracing board used in the Ozone Panel System as supplied by Eggers has been marketed and supplied by Hyne Australia as OS Brace, and has been available in Australia and certified as complying with the performance requirements of the BCA. 1 General: 1.1 Ozone panels consist of a rigid Polyisocyanurate (PIR) foam core which has been bonded to15mm OSB (oriented strand board) boards mounted each side to form a sandwich panel. The core and OSB face boards 1.2 Are formed to create a composite insulated structural sandwich panel. This sandwich panel is designed to be able to resist combinations of axial and bending forces. 1.3 The panel core is rebated during manufacture in the factory to take timber top and bottom plates and vertical splines which enable the panels to be simply fitted together on the construction site during site. This form of 3 construction also allows for the transmission of live and dead loads between levels of framing/support. The panels are 1200mm wide and up to 3m high (general maximum panel height is 2.8m). 1.4 EUROSTRANDR OSB The outer OSB board used in construction of the Ozone panel is EUROSTRANDR OSB This is a is a flat hardboard with a three-layer structure of oriented distributed strands (micro-veneers) according to DIN EN 300. The special strand geometry (length up to 160 mm) has a high degree of strand orientation in the grain direction of the outer layer which assures outstanding technical characteristics and very good inherent stability. EUROSTRANDR OSB boards for use in humid conditions are made with 100% formaldehyde-free adhesives. Raw material used in the OSB Board is: Debarked softwood from domestic forestry Paraffin wax emulsion PU resin Water 1.5 STRUCTURAL-PHYSICAL CALCULATION VALUES EUROSTRANDR OSB 3 E0 according to EN 300:2006 Characteristic Standard Unit OSB3 Raw density EN 323 kg/m3 600 μ-value EN ISO Thermal conductivity λr Specific thermal capacity c Reaction to fire 24h thickness swelling Linear expansion per 1 % change of moisture content Formaldehyde emission EN W/(mK) 0.13 DIN J/(kgK) 1,700 EN ( 9 mm) D- s2, d0 EN 317 % 15 EN 318 %/% 0.03 EN PPM < The Polyisocyanurate (PIR) used injected into the core is manufactured by Bayer Germany. The Bayer (PIR) onestep process to produce natural-oil polyols (NOPs) this product has been tailored specifically for the construction of the Ozone Panel system. 1.7 The use of PIR in the Ozone Panel is an important future in that it imparts properties which are vital to the overall

4 performance of the finishes Ozone panel. Stresses from positive and negative wind loads, air pressure imbalances are efficiently transferred from the OSB panels to through the foam core creating a robust composite structure. 2 Basic constructions: 2.1 The Ozone panels are manufactured as 90mm and 120mm thick. 2.2 External load bearing walls are required to be 120mm thick to have sufficient capacity to take combined axial and bending forces. 2.3 Internal load bearing walls may be 90mm thick depending on load and height. 2.4 connected and strengthened with a variety of combinations of timber top and bottom plates and timber (or steel) or special Ozone panel vertical splines. 2.5 Ozone splines: Ozone splines consist of 90mm wide lengths of Ozone Panel of thickness to fit inside the rebated panels and enable nail connection. The use of timber vertical splines at panel joints serves to enhances the panel load capacity, particularly for taller walls where horizontal joints in the panel may be required. 3 Benefits: The Ozone Panel Construction System provides the following benefits: 3.1 The Ozone Panel system is a load bearing precast panel that can be used for exterior structural walls, floors, roofs and interior walls. 3.2 An Ozone Panel is comprised of FSC certified OSB3 board made by Egger and a unique structural Polyisocyanurate (PIR) foam. 3.3 A 120mm Ozone Panel has an R-rating of 4.0, meets acoustic requirements for party-walls. 3.4 Ozone panel has a 60/60/60 fire rating using a single sheet of 16mm Boral Firestop. 3.5 Ozone panel has and a C4 cyclone rating. 3.6 The specially formulated Polyisocyanurate (PIR) virtually eliminates the risk of mould and bacterial growth thanks to its ability to repel water and vapour. 3.7 The Ozone panels are also fibre free, so there s no risk from airborne contamination. 3.8 Engineered joints give excellent air tightness for further protection. Lengths of up to 18m give you more flexibility in design and can speed up construction The Core of the Ozone panels provides fire resistance of up to 1 hour. When exposed to flame, given that the PIR forms a strong, carbonaceous char that protects the core foam from ignition Ozone Panels are manufactured from a mixture of two principal liquid components and a number of additives to produce highly cross-linked polymers with a 90% closed cell structure providing an excellent resistance to moisture penetration can be erected on any flooring system, giving you unlimited design possibilities, while saving the usable area Any changes can be made to existing properties: extra rooms or floors, attic, within a short time to reach the final desired result Ozone Panel constructions are certified for 60 years lifespan, while the concrete buildings have a scientific lifespan of 50 years The basic Ozone Panel construction cost is 30% less than conventional concrete buildings Exact construction planned costs and precise quantity of materials needed, as on site cutting and fabrication are eliminated Factory prefabrication to exacting ISO9001 quality standards ensures a high quality product conforming to the National Construction Code Low cost modifications and fast rate of construction, which will minimise the time, cost and labour Major running and maintenance cost savings over the lifetime of the building, therefore extremely low costs on energy, repairs or design changes The Ozone Panel wall is load-bearing and pre insulated, meaning the weatherproof, structural shell is completed much quicker than traditional methods of construction Erection times are known in advance, therefore Ozone Panel technology offers an accurate delivery date of your turn-key building. 4 BUILDING CODE OF AUSTRALIA COMPLIANCE 4.1 BCA volume Two Part 2.1 P2.1Structural Stability and Resistance to Actions The Ozone Structural Insulated Panel (Ozone SIP) system is intended as an alternative solution to the Building Code of Australia (BCA), Deemed to Comply Timber Framing design as specified in Part of the BCA Volume 2 for Class 1 and 10 buildings. 4.2 For the purposes of CodeMark certification the Ozone Panel System is limited to wall framing as an alternative to the timber wall framing as described in the Australian

5 Standard AS1684 Residential Timber Framed Construction. 4.3 When fabricated, designed and constructed in accordance with the limitations as specified in this Assessment Brief, the Ozone Panel System is deemed to comply with the Performance Requirements of P2.1 of BCA - Volume Tests conducted by Vipac Engineers and Scientists a NATA accredited testing facility have demonstrated that the Ozone Wall Panel System is capable of: 1. Supporting permanent and imposed loads in with AS1170.1, 2. Withstanding wind loads in accordance withas Supporting snow and ice actions in accordance with AS and: 4.earthquake loads in Accordance with AS Additionally the Ozone panels provide an integral bracing capacity, replacing the need for applied bracing sheets as is typically used in timber framed construction. 5 Fire Performance 5.1 The International Building Code requires specific fire performance characteristics for foamed plastics used in building construction, and that they are tested in accordance with ASTM E84 Standard Test Method for Surface Burning Characteristics of Building Materials. 5.2 Ozone Panel system has been tested by -Exova- Warringtonfire, Dandenong Victoria in accordance with AS and achieved a FRL of 60/60/ In the opinion of Bligh Tanner Engineers the Ozone Panels System will perform similarly to a stud wall constructed in accordance with the requirements of AS1684 Residential Timber Framed Construction. 5.4 The Ozone Panels System has demonstrated Attack Levels BAL 40 with the necessity for non-combustible cladding in accordance with AS3959 Construction of Buildings in Bushfire-Prone Areas. 6 Durability 6.1 The OSB/3 facing boards require protection from weather with a complete weatherproof Cladding system similarly to a timber stud frame. 6.2 The boards are designed for Service to Class 2 of section 2.03 wood-based panels of in accordance with Eurocode 5. Eurocode 5 covers the design of timber buildings and civil engineering works. Relevant standards referenced under section 2.03 are: IS EN 300: Oriented Strand Board (OSB) -Definition, classification and specifications 5 IS EN 312-4: Particleboards - Specifications - Part 4 IS EN 312-5: Particleboards - Specifications - Part 5 IS EN 312-6: Particleboards -Specifications - Part 6 IS EN 312-7: Particleboards - Specifications - Part 7 IS EN 622-2: Fibreboards - Specifications - Part 2 IS EN 622-3: Fibreboards - Specifications - Part 3 IS EN 622-4: Fibreboards - Specifications - Part 4 IS EN 622-5: Fibreboards - Specifications - Part 5 IS EN 636-1: Plywood - Specifications - Part 1 IS EN 636-2: Plywood - Specifications - Part 2 IS EN 636-3: Plywood Specifications - Part 3 IS EN : Wood-based panels - Part 1 IS EN : Wood-based panels - Part 2 IS EN 12871: Wood-based panels - Performance IS EN 13986: Wood-based panels - Characteristics IS EN 14374: Structural laminated veneer lumber - requirements 7 The Ozone Panel Structural System 7.1 The Ozone Panel transfer vertical loads through axial compression (or tension in the case of resultant wind uplift) in the OSB facing boards. The OSB resistance to buckling is greatly enhanced by the bending stiffness of the overall composite action of the fabricated panels. 7.2 Vertical load is transferred into and out of the panels via the nailed connection of the top and Bottom plates. 7.3 Test loading has shown that the panels have very high ultimate strength in compression (VIPAC loaded the 120mm panels up to 100kN/m length without failure), however this capacity in part relies on even bearing of the OSB sheets on the supporting surface. 7.4 To account for tolerance in construction, the load charts that are included in this Assessment brief conservatively rely on vertical load transfer via shear in the nails that connect the OSB to the plates. 7.5 Horizontal wind loads are transferred to top and bottom plates via bending action in the panels. The OSB facings act as flanges resisting compressive and tensile forces induced by bending action. 7.6 Shear is transferred through the OSB and PIR core. The design model that is used to derive the Design Charts, accounts for reduced bending stiffness due to shear deformation in the panel and is calibrated with the deflection results from the VIPAC testing. 7.7 The combined bending and axial design charts are derived with an axial load eccentricity of panel thickness/ The capacity of the panel system to resist the combined vertical and horizontal loads may be increased by inclusion of timber studs/posts at panel joints (1200cts). The capacity of these additional members (and combined system capacity) may be determined in accordance with AS1720 Timber Structures.

6 7.9 Situations that may require additional vertical studs include at concentrated loads, beside openings, tall walls, high wind areas and the lower storey of two storey buildings Loads over openings must be supported by lintels housed into the Ozone panels in a similar fashion to conventional timber framing in accordance with AS1684. Lintels shall be designed in accordance with AS The Ozone panels provide resistance to horizontal racking forces, in a direction parallel Loads are transferred into and out of the OSB boards via the nail fastening to top and bottom plates. The bottom plates are bolted to the supporting structure. At this stage, the minimum length of individual bracing panels used to determine design capacity is 2.4m (2 panel length) as this is the system that has been tested 8 load bearing: 8.1 Bligh Tanner Engineers have calculated the Load bearing capacity of the Ozone Panel System Based on the following two principal factors: 1. Maximum allowable compressive stress in the OSB facings induced from the combination of axial and bending forces. 2. Maximum capacity of nail fastening of the OSB facings to the top and bottom plates. 8.2 Serviceability deflections under wind load have also been checked by Bligh Tanner Engineers in accordance with values recommended in AS1684 Residential Framing Code 8.3 The Design Charts are based on the following construction system: 63mm deep LVL top plate (or 45x90mm mgp12 ribbon plate) 45mm deep LVL (or mgp12) bottom plate OSB vertical splines at 1200 cts Full height panels without horizontal joins Maximum eccentricity of vertical loads of panel thickness/4 (floor and roof loads must be supported on to the wall top plates, not off the OSB facing). 9 Thermal : 9.1 The Ozone Panel System has achieves a Thermal resistance commensurate with the panel sizes as tested by Vipac and represented in the graphs below. 6

These values are useful for confirmation of capacities derived for the 15mm OSB faced Ozone panels. The Eggers OSB/3 board also has British Board of Agreement (BBA) certification CODEMARK CERTIFICATION: CodeMark is a building product certification scheme. The CodeMark scheme supports the use of new and innovative building products by providing a nationally and internationally accepted process for products to be assessed for compliance with the requirements of the building codes of Australia and New Zealand. The scheme provides confidence and certainty to regulatory authorities and the market through the issue of a Certificate of Conformity. INSPECTIONS: CMA Assessment Brief representatives have inspected installations of the systems and found the level of performance satisfactory. ENVIRONMENTALLY STATEMENT: Given that the construction industry is a significant contributor to greenhouse gases any innovative product that can assist in the reduction of C02 in the environment must be considered a Future Friendly Product. Cement production alone accounts for five per cent of all global carbon dioxide emissions that is more than the entire aviation industry. Regrettably the long-term trends in the use of Cement are increasing exponentially: it is estimated that by 2020 the demand for cement will increase by as much as 50 per cent. The OSB board used in the Ozone panel system binds approximately 864 kg CO 2 per M3 (calculation based on GWP 100 production) This corresponds to the average CO 2 emissions for a mid-size car over a distance of 6,647 km. 65% of the materials used in Ozone Panel can be used again after lifespan period, compared to 25% on concrete, 35% on steel structure and 65% on conventional timber frame The ABCB and New Zealand s Department of Building and Housing (DBH) manage the scheme in their respective countries. The Joint Accreditation System of Australia and New Zealand (JAS-ANZ) have accredited CertMark to evaluate and certify building products. Relevant legislation requires building control authorities to accept CodeMark certified products. Date 14/12/12 John Thorpe Director CertMark Australasia Pty Ltd There is no "heavy" industry production for iron, cement, aggregates, bricks etc. needed The materials used in the manufacture of the Ozone panels comes from one source only, as an integrated building system, therefore there is less impact on the environment. There is less air & water pollution, gas emission, CO2 emission compared to other systems (concrete, bricks, steel) on the construction stage as well as on the running period of the building (due to the energy efficiency and air tightness). The Ozone panel Company has been audited by CMA as compliant with ISO14001 Environmental Management and has been certified a: Future Friendly Company. 8
