| Use advice for data set | Scope: This document applies to DuPontTM Tyvek® FireCurb® 2066B, which is a high-density polyethylene (HDPE) membrane. The declared unit weight is 68 g/m2. LCA data were compiled using production data for the year 2019 for monolayer and finishing processes (used for EPDs of Tyvek® Monolayer published in 2021) and data for the year 2021 for the coating process. The declaration holder is responsible for the underlying data and its verification. System boundary: Type of EPD: Cradle-to-gate (with options) The system boundaries of the EPD follow the modular construction system as described by EN 15804. The LCA considers the following modules: A1-A3: Manufacturing of pre-products, packaging, ancillary materials, transport to the factory and production, with the associated energy supply and waste handling A4: Transport to the construction site A5: Installation into the building including disposal of packaging C4: Waste disposal, namely incineration D: Potential for reuse, recovery and/or recycling including benefits for product incineration from module C4 | ||
| Technical purpose of product or process | The product is used on the cold side of building facades. It is placed in front or behind insulation and will improve water and wind tightness during construction and the lifetime of the building. | ||

| General comment on data set | DuPont™ Tyvek® FireCurb® is a lightweight, advanced, fire-retardant membrane that self-extinguishes when ignited. It uses halogen-free flame-retardant additives to reduce the formation of droplets and smoke with minimal environmental impact. Tyvek® FireCurb® takes the airtight and watertight yet vapour-open breather membranes of Tyvek® membranes and adds flame retardancy properties that can significantly increase building safety. Suitable for use in all building types, from bungalows to high-rises. For the placing on the market of the product in the European Union/European Free Trade Association (EU/EFTA) (with the exception of Switzerland) Regulation (EU) No. 305/2011 (CPR) applies. The product needs a declaration of performance taking into consideration EN13859-2: Flexible sheets for water proofing – Part 2: Underlays for walls and the CE-marking. For the application and use the respective national provisions apply. | ||

| Technology description including background system | DuPont™ Tyvek® Firecurb™ is produced with DuPont’s own flash-spinning process and includes an additive that provides the improved fire class. First mother rolls are produced in the plant in Luxembourg. The final step is the printing, converting to customers’ dimensions specifications and final packaging, in another plant in Germany. The main materials used are the HPDE granulates and in a lesser extent the fire retardant additive. Other materials used in smaller quantities involve hydrocarbons for sheet manufacturing, colour paste for printing, and packaging materials. Declared unit: This declaration applies to 1 m2 of DuPont™ Tyvek® 2066B membrane, with a declared unit weight of 68 g/m2. | ||
