| Use advice for data set | Scope: The life cycle assessment is based on production data of Duripanel A2 of the year 2018 at the production site of Etex Germany Exteriors GmbH in Beckum, Germany. The results of the life cycle assessment provided in this EPD are based on a thickness of 19mm and are globally valid. The LCA results for additional thicknesses are declared in an annexe to this EPD. System boundary: Type of the EPD: cradle to grave. The following life cycle stages and modules are included: Production stage (A1-A3): manufacturing of pre products and transportation to the manufacturing site energy consumption during production recycling and disposal of production wastes production of packaging Construction stage (A4-A5): transportation of product to the construction site energy consumption during the installation of products production of fixing material disposal of installation wastes including emissions of biogenic CO2 from the wood content incineration/recycling of packaging materials (potential benefits from energy substitution within the incineration process are declared in module D) including emissions of biogenic CO2 from renewable packaging materials Use stage (B1-B7): efforts for the use of the product, maintenance and operational efforts modules B3, B4, B5 are declared as MNR (module not relevant) according to the IBU requirement. These modules are defined on building level in general. End-of-life stage (C1-C4): Two end-of-life scenarios were considered: 1) Scenario 1: 100% recycling in cement plant. Due to the wood content of Duripanel B1, the shredded product can reduce the use of energy in the cement plant during cement clinker production. Simultaneously, the other raw material components in the wood cement boards help to reduce the use of virgin raw materials in the cement plant. Energy and material credits were assigned using the substitution approach. The resulting credits from energy recovery and material recycling are assigned to module D. 2) Scenario 2: 100% landfilling. For both scenarios, the following processes were included: energy consumption for deconstruction and demolition transportation to disposal waste processing and recycling or landfilling of product Loads and benefits beyond system boundary (D): loads and benefits from recycling/landfilling of production waste, packaging, installation losses and product waste. | ||
| Technical purpose of product or process | The Duripanel A2 base panel with straight edges can be used for high-quality interior finishing, roof formwork, timber construction and container construction with increased fire protection requirements for non-combustible building materials. The Duripanel A2 installation panel with tongue and groove can be used for load-bearing formwork and dry subfloors with high compressive strength and chair castor suitability (screw-fixing) with increased fire protection requirements for non-flammable building materials. | ||

| General comment on data set | Duripanel A2 is a three-layer cement-bonded particleboard according to EN 634-1 and -2 for internal and external construction applications. It mainly consists of the natural raw material wood particles and cement. It is being produced in different thicknesses between 10 and 32 mm. It is available in an unsanded smooth or sanded surface, with smooth trimmed edges or with tongue and groove. The surface colour is mainly being characterized by the fine wood particles in the outside layers. | ||

| Technology description including background system | The production of large-format panels from wood cement takes place according to a largely automated, semi-dry spreading process in which no excess water is produced. In a mechanical mixer, the litter mixture of wood chips, cement, recycled material from trimming waste, auxiliary materials and water is processed. The material is evenly distributed on carrier plates via a mechanical throw sifting system. Excess material at the edges is returned directly to the spreader. The scattered material is pressed, stored in a climatic chamber for setting (heat exchanger, steam generation via natural gas), the hardened sheets restacked, trimmed and temporarily stored for 28 days. The panels are then dried in a circulating air oven to the moisture content required for delivery. The quality management system of the company and the production facility are certified according to ISO 9001:2015. Technical data: The constructional data shown in the table are valid for all thicknesses and surfaces (sanded/unsanded), unless where indicated otherwise. Declared unit: The functional unit declared in this EPD is 1m² of Duripanel A2 with a thickness of 19mm (abbreviated as 1m²19mm). In an annexe to this EPD, the LCA results for the other existing thicknesses are declared. | ||
