| Use advice for data set | Scope: This EPD refers to the life cycle of RESITRIX® CL and RESITRIX® MB roofing and waterproofing membrane systems manufactured by Carlisle Construction Materials GmbH based in Hamburg. It involves hot-air welded waterproofing membranes based on synthetic EPDM rubber with a glass fibre backing. The underside features a polymer-modified layer of bitumen. The EPDM layer is manufactured in Hamburg. The product is coated with polymer-modified bitumen in Waltershausen (Thuringia). System boundary: Type of EPD: cradle to plant gate – with options. The LCA takes account of the provision of raw materials and energy, raw material transport and product manufacturing (Module A1-A3) as well as transport after de-construction (Module C2), waste treatment (thermal utilisation, Module C4) and benefits and loads outside the system boundary for thermal utilisation (Module D). |
| Technical purpose of product or process | RESITRIX® CL is suitable for all types of installation (except loose installation for green roofs). This roofing membrane can be applied using PU adhesive. It can also be glued directly to expanded polystyrene (EPS). RESITRIX® MB can be installed: loose laid with mechanical fixings and loose laid with ballast (except for green roofs). The manufacturer's installation instructions must be observed. |

| Technology description including background system | The mixture comprising the individual polymers and respective aggregates is produced in Hamburg in a discontinuous process in an inner mixer automatically receiving the polymers, filler, carbon black, mineral oil, processing auxiliaries and cross-linking via dosing and weighing systems. The ensuing mixture is processed as sheets with a glass fibre backing in a four-roller calender. This is followed by cross-linking (vulcanisation) the elastomer sheeting in automatic vulcanisation machines. This production stage is also performed in Hamburg. Stringent quality controls are followed by coating with polymer-modified bitumen in Waltershausen. The polymer-modified bitumen mass is produced using an intensive mixer with downstream agitators. This fully-automatic process includes another quality check, cutting to length, banding and packaging for transport on pallets. Development and production are subject to the quality management system introduced in accordance with EN ISO 9001:2008. External quality checks and tests related to in-plant production control are carried out at regular intervals by independent test institutes, e.g. - National Material Testing Office NRW/Dortmund - BBA (British Board of Agreement Cert. No. 06/4329), UK - FM Approvals (Approval Ident. No. 3036376), USA - KIWA (KOMO attest K75248-01), The Netherlands - BUtgb (ATG 07/1790), Belgium and others. Declared unit: The declared unit is 1m² roofing membrane in the RESITRIX® system. |
