1 Insulated sandwich panel cover with a wide range of decorative finishes

2 At Garnica, we challenge the ordinary in order to become a worldwide leader in our sector, producing extraordinary plywood sourced from sustainable plantations. Sustainability - Managed forests - One hectare of poplars captures 11 tons of CO 2 annually % of wood used

3 Composition of the panels Plywood board with decorative finish XPS thermal insulation or wood fibres Durable plywood board Plywood board with decorative finish in natural wood or laminates: - Maple - Globulus - Laminates (HPL) white, grey, glossy, matt, etc. * Consult our sales personnel for other options Thermal insulation: XPS, extruded polystyrene with high compressive strength, 100 mm thick. High density wood fibres, 100 mm thick.

4 Top plywood: Plywood board with Class 3 adhesive, resistant to outdoor humidity conditions. Durable plywood board with Class 3 adhesive and fungi- and insect-resistant treatment, guaranteeing maximum durability. -Minimum swelling * 3.8% swelling after 24h in water -High mechanical performance * MOE= 4200 N/mm² Thermal transmittance G-Brick COVER panels stand out due to their high thermal insulation thanks to their 100 mm XPS or Wood Fibre core, while benefiting from the low thermal conductivity of the wood. The thermal transmittance of the various compositions is therefore: - G-Brick COVER with 100 mm of XPS: u = 0.32 W/m²K R = m 2 KW -1 - G-Brick COVER with 100 mm of wooden fibres: u = 0.36 W/m²K R = 2.77 m 2 KW -1

5 Weights and dimensions In order to facilitate its installation in covers (where the handling capacity of the panels by a single person is a priority) in a way that facilitates its placement and reduces the risk of accidents at work, we have created a standard panels measurement of: 2,400 mm x 590 mm This allows us to take the panels to 3 supports, with both a wooden and metal structure, and with axes between beams at 1200 mm. Thanks to our plywood panel manufacturing system, we are able to create very high panel measurements, which can reach a maximum of 3000 mm x 1500 mm, and which for large surfaces can be a very interesting combination, with supports for 1500 mm axes. For more details, consult our technical department. Based on the standard 2,400 mm x 590 mm measures, and taking into account a density of the plywood board of 450 kg / m³, an insulation density of XPS of 35 kg / m³, and a wood fibres density 140 kg / m³, the weights of the panels are: - G-Brick COVER with 100 mm of XPS: 17.7 Kg per panel - G-Brick COVER with 100 mm of wooden fibres: 32.7 Kg per panel Carbon footprint At Garnica, we work for an active reduction of the carbon footprint in the manufacturing processes, obtaining 100% use of the tree. We exercise control over and knowledge of the whole life cycle of wood, from the choice of the best clones in the nursery, for their optimal adaptation to the conditions in the plantations, to the industrial process of the tree 14 years later, when we dedicate the majority of the wood to the plywood board, and we manage the rest (bark, branches, etc.) in order to obtain energy (biomass) that supplies our factories. All this, together with minimum movements of raw material, as our plantations and factories are located in in those geographical environments where historically a quality poplar wood for the plywood has been obtained.

6 Quality control In our factories, we have a technical team specialising in the quality control of both the industrial process of the plywood board and the G-Brick COVER panels. In this way, we can verify in our laboratory that the panels meet all the necessary requirements so that they fulfil their functions in construction projects and ensure their maximum durability. Mechanical resistance of the G-Brick COVERS For the G-Brick COVER application, we have tested panels at Tecnalia Research & Innovation, experts in mechanical testing for structural applications. These tests were performed according to the ETAG 016 "Self-supporting composite lightweight panels standard, resistance to positive bending according to Annex C1 of part 1. The objective is to obtain the stress-strain curves of the panels, from which the characteristic values of the breaking load and the load values that produce different levels of deformation will be extracted. We also want to know the failure modes of the panel (compression breakage in supports, breakage of shear between layers or in some of them). The tests were performed with the panels supported at three points and two spans of 1150 mm between support centres (panel length 2,400 mm). The supports were made on 100 mm wide steel plates (simulating a real situation of wood or metal beams) over the entire width of the panel. These supports were articulated allowing rotation about their longitudinal axis. In the test with three supports, the load is applied in 8 points, as explained in Figure 2a of Annex C1 of Part 1 of ETAG 016.

7 Test Results - G-Brick COVER with 100 mm of XPS: Starting from the most unfavourable resistance result of the samples tested, and taking into account the load value produced by a L/200 deflection, the force supported by the panel was 41,746 N. Taking a safety margin of reduction of 40% resistance, and applying that load to 1 square metre, the maximum recommended load per m² is: 17,387 N/m² = 1,773 Kg/m² Force-displacement graph for XPS insulation - G-Brick COVER with 100 mm of wooden fibres: Starting from the most unfavourable resistance result of the samples tested, and taking into account the load value produced by a L/200 deflection, the force supported by the panel was 19,993 N. Taking a safety margin of reduction of 40% resistance, and applying that load to 1 square metre, the maximum recommended load per m² is: 8,330 N/m² = 849 Kg/m² Force-displacement graph for XPS insulation Tools required For the installation of the panels, we will have different types of anchors depending on the main structure, either wood or metal. In annexes 1 and 2, these panel joints are detailed at the construction level and the screws required for their correct fixing are: - Wood screws, 6mm diameter and length depending on thickness, taking into account the recommendations described in the attached details.

8 - Metal screws, 6mm diameter and length depending on thickness, taking into account the recommendations described in the attached details. Water vapour permeability UNE EN 13986: Boards derived from wood for use in construction. Characteristics, conformity assessment and marking. For more details on the permeability regulations, we have the international ISO 9346 standard and the UNE-EN 12086:2013 standard for the test in a desiccator and to analyse the elements. The Sd value of a material, its resistance to the passage of water vapour, is a characteristic required for calculating the condensations that can be produced inside the materials. In the case of G-Brick sandwich panels, it depends on the sum of the Sd value equivalent to the thickness of both boards (10 mm) and the equivalent Sd value of the XPS or wood fibres (in their corresponding thickness of 100 mm). To arrive at the Sd value, we need to know the "μ value (factor of resistance to the passage of water vapour), which is a dimensionless value for each material, and we can introduce it in the following formula by multiplying it by the thickness of each material that composes the G-Brick panel: Garnica plywood panel: µ, Water vapour resistance factor* 70 *According to Table 9 of UNE EN standard XPS isolation: µ, Water vapour resistance factor* 50 *Declared by the manufacturer Insulation of wood fibres: µ, Water vapour resistance factor* 3 *Declared by the manufacturer

9 Sd value example for G-Brick COVER 10/100/10 panel with XPS 10/100/10 mm (plywood XX / XPS / plywood YY) Plywood XX µ = 70 XPS µ = 50 Plywood XX µ = 70 Sd equivalent XX: 0.01 m * 60 = 0.7 m Sd equivalent XPS: 0.1 m * 50 = 5 m Sd equivalent YY: 0.01 m * 60 = 0.7 m Sd value of G-Brick COVER 10/100/10 = 6.4 m Sd value example for G-Brick COVER 10/100/10 panel with wood fibres 10/100/10 mm (plywood XX / XPS / plywood YY) Plywood XX µ = 70 XPS µ = 3 Plywood XX µ = 70 Sd equivalent XX: 0.01 m * 60 = 0.7 m Sd equivalent YPS: 0.1 m * 3 = 0.3 m Sd equivalent YY: 0.01 m * 60 = 0.7 m Sd value of G-Brick COVER 10/100/10 = 1.7 m After studying the application of the panels in high energy efficiency projects, it could be summarised that there is never condensation inside the panels and at the same time a vapour barrier against the interior is not required.
