| Use advice for data set | Scope: Die vorliegende Umwelt-Produktdeklaration bezieht sich auf 1 m best wood BSH, welches von der Firma Holzwerk Gebr. Schenider GmbH am Standort Eberhardzell (Deutschland) hergestellt wird. System boundary: This EPD is a cradle-to-grave analysis and module D, it includes the following life cycle phases: A1-A3 | Production stage The production stage includes the manufacture of all components of the declared product (wooden slats and adhesives) as well as the packaging, including the respective upstream chains up to the extraction of raw materials. The transportation of the components and packaging materials to the production site is also taken into account. All expenses for the production of the glulam elements are taken into account within the factory limits. A4-A5 | Construction stage This stage includes the transportation of the GLULAM elements to the construction site (A4) as well as the expenses for installation in the building (A5). Furthermore the disposal of packaging waste is taken into account here. B1-B7 | Utilisation stage This utilisation stage deals with the phase of the product. However, if used properly, no environmentally relevant processes occur during the period of use. C1-C4 | Disposal stage The disposal stage includes dismantling (C1), which in this case was assumed to be a manual process with negligible environmental impacts. Furthermore, the transportation of the dismantled product, which is therefore waste, to the waste treatment plant (C2) and its thermal recovery (C3) are also taken into account. In this case, no environmentally relevant processes are included in C4. D | Advantages and drawbacks outside the system boundary The advantages of thermal recycling of offcuts and packaging waste (from A5) and of the product itself (from C3) are considered here. | ||
| Technical purpose of product or process | The product best wood GLULAM is used in the structural area of modern timber construction. The areas of application include residential, industrial and bridge construction. It can be used in utilisation classes 1 and 2 in accordance with EN 1995-1-1. | ||

| Technology description including background system | In production, technically dried wood slats with a moisture content of 8-15% are used, which are sorted according to strength and pressed into endless slats using a finger joint. These slats are cut to an individual length during the production process, then levelled and pressed into GLULAM wooden beams. Each GLULAM product is planned to order size at the end. When used as a ceiling element, the components are additionally profiled and processed by a CNC-controlled joinery system as required. If required, the surface of the ceiling elements can be finished before packaging. Technical data: The technical construction data shown below is valid for the product best wood GLULAM mat as delivered. Depending on the cross-sectional structure (number of layers, layer thickness) and the load position of the best wood GLULAM, the physical building properties such as component resistance or fire resistance vary. Strength classes from GL 24 are available for dimensioning in accordance with EN 1995-1-1 and these are designed in a homogeneous structure. Declared unit: The declared unit for this Environmental Product Declaration is defined as 1 m in accordance with the specifications of the corresponding PCR: Solid wood product. The gross density of the product in question is 430 kg/m with a delivery moisture content of 10 %. | ||
