| Use advice for data set | Scope: This Declaration applies for wood fibre insulating board manufactured in a dry process by GUTEX at its location in Waldshut-Tiengen. This document is translated from the German Environmental Product Declaration into English. It is based on the German original version EPD-GTX-20140222-IBC2-DE. The verifier has no influence on the quality of the translation. System boundary: EPD type: cradle to gate – with options This Environmental Product Declaration refers to the product stage (Modules A1-A3, including provision of raw materials, transport, manufacture and packaging materials). Furthermore, an end-of-life scenario (Module D) was also calculated: incineration in a biomass power plant with energy recovery. The utilisation of packaging materials is not taken into consideration as Module A5 is not declared. |
| Technical purpose of product or process | GUTEX insulating materials can be used in both old and new buildings: as a thermal insulation composite system for the entire building facade, wall insulation for back-ventilated facades, on-roof and/or cavity insulation plus false ceilings, insulating ceilings between floors, interior insulation of external walls, insulation of installation levels and impact sound insulation for floors. |

| General comment on data set | GUTEX wood fibre insulating boards are board-shaped wood-based materials manufactured from wood fibres in accordance with /DIN EN 13171/. By adding low quantities of PUR resin, insulating boards are manufactured from wood fibres in a dry process. They are then cut online, and profiled and finished where necessary. Water-repellent and non-water-repellent single-layer insulation panels can be manufactured to a thickness of 240 mm. |

| Technology description including background system | The manufacturing process is broken down into the following process steps: 1. Delivering the wood chips 2. Defibering the wood chips using the defibrator process 3. Hydrophobing the fibres with paraffin 4. Drying the fibres with PUR resin 5. Glueing the fibres with PUR resin 6. Scattering the fibres on the forming belt to form a mat 7. Curing the mat in the calibration and hardening unit 8. Dividing up, profiling and assembling The location is certified to /DIN EN ISO 9001:2008/. Technical data: The following technical (construction) data is of relevance for GUTEX wood fibre insulating boards on delivery. Declared unit: The unit taken as a basis for the Declaration is one cubic metre (1 m³) wood fibre insulating board with an average weighted density of 173 kg/m³ by production volume (m³/year). |
