| Technical purpose of product or process | Bilaminate membranes are versatile solutions suitable for roofing, façade, and wall assemblies. By selecting the appropriate type, they can be easily adapted to a wide range of thermal and moisture management needs. Typical applications include use as underlay membranes, wind barriers, or additional moisture protection layers. |

| General comment on data set | MASTERPLAST’s bilaminate (two‑layer) products are composed of two distinct layers joined through a controlled thermal bonding process. The base layers are typically made from polymers such as polypropylene (PP) or polyethylene (PE) nonwoven materials, combined with additional functional membranes. These materials are designed for use in sectors including construction, healthcare, hygiene, automotive applications, and industrial filtration. Their functional characteristics include increased mechanical strength, resistance to water penetration, vapor permeability, and resistance to various chemicals. The layered configuration can be adapted for specific technical requirements, such as acting as a vapor barrier or incorporating antibacterial or flame‑retardant properties.

The quality level of technical representativeness can be considered “good”. The time representativeness can also be regarded as “good”. The overall data quality for this EPD can, therefore, be described as “good”. To ensure the comparability of the results, only consistent background data from the ecoinvent database version 3.9.1 (2022) was used in the LCA (e.g. data sets on energy, transports, auxiliary and operating materials). The database is regularly checked and thus complies with the requirements of EN 15804 (background data not older than 10 years). Almost all consistent data sets contained in the ecoinvent database version 3.9.1 are documented and can be viewed in the online documentation. The raw material data were converted into reference flows (input per declared unit).The general rule was followed that specific data from specific production processes or average data derived from specific processes must have priority in the calculation of an LCA. Data for processes over which the manufacturer has no influence were assigned generic data. The LCA calculation was carried out using Nibe's LCA & EPD tool R<THINK. This specific EPD is based on the product variant with a basis weight of 50 g/m². Environmental impacts are calculated per kg of product and converted to per m² using a normalized conversion factor of 1.000 for the declared product. For other commercially available basis weights, the following conversion factors can be applied proportionally. Basis weight (g/m²)Normalized conversion factor (relative to specific EPD)400.800501.000 601.200701.400801.600901.8001002.0001102.2001202.400To derive environmental indicators per m² for any other product variant, multiply the results of this specific EPD by the appropriate factor. The additives account for approximately 1.04% of the total material used. As this falls below the cut-off threshold, they are excluded from the system boundaries in this EPD. The environmental impact results in this EPD are based on the total production data of bilaminat products in various colors. The Environmental Product Declaration complies with the principles of “polluter pays” and “modularity,” ensuring that waste management responsibilities and impacts are allocated appropriately and consistently. |
