| Use advice for data set | Scope: Die vorliegende Umwelt-Produktdeklaration bezieht sich auf 1m best wood CLT BOX, welches von der Firma Holzwerk Gebr. Schneider 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 CLT BOX elements are taken into account within the factory limits. A4-A5 | Construction stage This stage includes the transportation of the CLT BOX 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 | Utilization stage This stage deals with the utilization 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 CLT BOX 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 | The best wood CLT BOX product is manufactured by combining the best wood CLT and best wood BSH products. In the first processing step, 2-3 glulam ribs are glued to a CLT panel as a base plate. Depending on the application, the cavity between the glulam ribs can be fitted with fixtures in the subsequent process. When used as a ceiling element, the product is pressed together with an upper CLT panel. Once the bonding has hardened, the final surface treatment is carried out using a profiling planer and the customised trimming and packaging. If required, the surface can be finished before packaging. Technical data: The technical construction data shown below is valid for the product best wood CLT BOX as delivered. Depending on the cross-section structure (number of ribs, rib width and height) and the load position of the best wood CLT BOX, the physical building properties such as component resistance or fire resistance vary. The design is carried out in accordance with EN 1995-1-1; the best wood STATICS software is available for preliminary design. 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 density of the wooden box element, taking into account the air gaps, is 200.58 kg/m at a delivery moisture content of 10 %. | ||
