| Use advice for data set | Scope: This EPD declaration is based on the average of one metric tonne UAC Fibre Cement Board manufactured by UAC Berhad. These products are produced in the manufacturing plant located in Ipoh, Perak (Malaysia) where the production data for 2022 was recorded. Life Cycle Assessment (LCA) was conducted based on the cradle-to-grave with option approach (Modules A1-A3, A5, C1-C4 & D). The Declaration holder is liable for the details and documentation upon which the evaluation is based. System boundary: Type of EPD: Cradle to gate with options. The following life cycle stages were included: A1-A3, A5, C1, C2, C3, C4 and D. Manufacture of preliminary products (cement, sand, pulp, alumina, silica fume and red pigment) and transportation of raw materials and preliminary products to the plant have been considered. Manufacturing process in the plan including energy, manufacture of auxiliaries, disposal of residual materials incurred and consideration of any emissions incurred. Manufacture of packaging materials has also been considered. | ||
| Technical purpose of product or process | For the application and use the respective national provisions apply. UAC Berhad manufactures a wide range of Fibre Cement Boards which are extensively used in residential, institutional, commercial and industrial buildings, as: - - Internal Lining and Wall Partitioning - Ceiling - Soffit and Eave Lining - Substrate for flooring - Fire and insulation application - Decorative application - Roofing - Others | ||

| General comment on data set | This is an average EPD comprises the products listed below. These autoclaved composite materials are made from specially treated high-grade cellulose fibre, Portland cement, refined sand and water. The asbestos was analyzed with a third-party laboratory and was not found in the product. The declared products include: - UAC Superflex/Multipurpose/Every - UAC Vistaboard/Flexaboard/Multiflex/Square Flex - UAC Lattice (Square, Diamond) - UAC Decoceil (Chemerah,Chemerah Plus, Tika, Angkasa, Forra, Forra Plus) - UAC Plank (Sedartex Woodgrain, Smooth) - UAC Plank Shiplap - UAC Supertex Panel - UAC Decowood (Woodlike, Smooth) - UAC Fence - UAC Skirting - UAC Duravent All the declared products are produced at the same process flow with the same raw material composition with difference of formulation and geometrical output. | ||

| Technology description including background system | Process flow of UAC Fibre Cement Board production: UAC Fibre Cement Boards are produced with Hatschek process or wet process: The raw materials are mixed homogeneously and pumped to the tubs at controlled rate so that tubs are filled and overflow. A uniform film is formed onto the sieves and the film will be picked up by felt which will then be transferred to a size roller to be rolled in layers for the manufacturing of `green sheet` (intermediate product formed during the production and yet to send to autoclave) according to the desired thicknesses. The speed of the felt is controlled in order to achieve consistent sheet thickness at a specified production rate. Individual size roller determines the length of sheet being produced. If patterned sheet is to be produced, a patterned sleeve will be placed on the size roller to create the desired patterns. Once the desired thickness is achieved, it will then be separated and taken off from size roller by a cut-off wire. The green sheet will then be trimmed into size by high pressure water jet while the remaining scraps will return to scrap agitator which will then transferred back to feed agitator for reuse in order to minimize waste generated. The trimmed green sheets are stacked in tiers on steel base pallet. The stacked green sheets will then be air-cured for minimum 6-8 hours before curing in autoclave for a total process duration of 10-12 hours. The autoclaved sheets will undergo further cutting or trimming into the final dimension at sheet finishing with either guillotine knife or rotating saw. Sanding, edge recessing and slotting are also being done at sheet finishing. Quality Management System in accordance to ISO 9001:2015 for design and manufacture of fibre cement products. Technical data: The technical data given by the Declaration of Performance according to EN 12467 apply. UAC Fibre Cement Boards conform and certify to (a) MS1296:2010 for UAC Superflex and (b) EN12467:2004 for 7.5mm UAC Sedartex Woodgrain Plank. Product specification UAC Fibre Cement Board (6mm thickness) - Thermal conductivity (W/mK): 0.12 - Resistance of heat transmission, Ra (m2K / W): 0.19 - Dry density (kg/m3): 1400 Soundproof: With a 6mm fibre cement sheet (1190mmx1190mm) installed in the opening between two adjacent but acoustically isolated reverberation rooms, 17-33dB sound transmission loss at frequency from 1255000Hz. Airborne noise insulation is determined as STC30 (tested in accordance with ASTM E90-09). The difference between the sound absorption of the room with and without the 6mm fibre cement sheet is determined to obtain the total sound loss by using the reverberation time values. Noise reduction coefficient is determined as NRC0.10 (ASTM E423-90a). Sound transmission loss (UAC Vistabord): Estimated 25dB (6mm), 28dB (9mm). Declared unit: All products show similar recipes with some differences in the dosage of pre-products for certain products. Declared unit to the UAC Fibre Cement Boards which are manufactured with the mixing of cement, silica sand, pulp, alumina, silica fume and red oxide and dried under pressure and temperature in the autoclave machine. Construction materials purpose, fixing and installation guides are being observed and no health impairment is known due to the basic materials employed and their behaviour according to current knowledge. Further information on the products can be referred to the Product Specifications from www.uac.com.my The average metric tonne of fibre cement products is calculated based on the annual production data. The declared unit of this study is 1 metric tonne of UAC Fibre Cement Boards with an average bulk density of 1400 kg/m. Foreground data describing the on-site production are integrated into the LCA FE Software model in the study. The LCI is assessed based on annual production data. Background data are taken from the LCA FE Database. | ||
