| Use advice for data set | Scope: This document applies to Sarnafil® TG 76 Felt PS polymeric waterproofing membrane in thicknesses of 1.5, 1.8 and 2.0 mm manufactured by Sika Services AG in CH-6060 Sarnen (Switzerland). The EPD covers the production of the waterproofing membrane, transport of the product to the construction site, installation of the waterproofing membrane, disposal, as well as benefits and loads outside the system limits. The model was calculated on the basis of production data for the thickness 2.0 mm provided by Sika Services AG from the year 2018. 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 takes into account the following modules: A1-A3: Extraction, processing and transport of raw materials (e.g. polymers, pigments, processing aids, stabilizers, fillers, flame retardants and carrier materials) used for the production of intermediate products and the waterproofing membrane and the packaging materials used to package the waterproofing membranes, such as wooden pallets, cardboard and PE film, for transport to the plant. Waste processing of production waste (edge trim), which occurs during the production of the waterproofing membrane. A4: Transport of the waterproofing membrane to the building site A5: Installation of the waterproofing membrane into the building by means of hot-air welding (including welding energy and water consumption), disposal or recycling of packaging, and waterproofing membrane scraps C1: Manual deconstruction and removal of the waterproofing membrane (recovery) C2: Transport of the recovered waterproofing membrane to waste-processing facility C3: Processing of the recovered waterproofing membrane by thermal energy recovery C4: Disposal of the recovered waterproofing membrane in landfill D: Benefits for reuse, recovery and/or recycling (through thermal energy recovery, recycling of the recovered waterproofing membrane and reuse of the wooden pallets) | ||
| Technical purpose of product or process | Sarnafil® TG 76 Felt PS polymeric waterproofing membrane is used chiefly to seal flat roofs. The roofing sheets can be fully adhered to unballasted roofs with a pitch up to < 20°. The manufacturer recommends the use of the Sika adhesive Sarnacol® 2142 S for adhered application of the membrane. Application on roofs with gravel ballast or in green roof systems is also possible. | ||

| General comment on data set | Sarnafil® TG 76 Felt PS polymeric waterproofing membrane is made of flexible polyolefin (FPO) and is treated with flame retardant and stabilizers against UV radiation and backed with a glass-polyester nonwoven mat (felt). A glass nonwoven inlay is encapsulated within the sheet. The glass-polyester felt backing serves as a bonding and leveling layer for adhered application over insulation layers consisting of expanded polystyrene (EPS) or polyurethane (PU). Sarnafil® TG 76 Felt PS polymeric waterproofing membrane is available in the following thicknesses: 1.5 mm (TG 76-15 Felt PS), 1.8 mm (TG 76-18 Felt PS) and 2.0 mm (TG 76-20 Felt PS). | ||

| Technology description including background system | Sarnafil® TG 76 Felt PS polymeric waterproofing sheets are manufactured on production lines developed in-house in the following stages: Melting of the polymeric components and additives in extruders Dispersing of the molten materials Coating of the carrier or the reinforcing in layers, producing homogenous encapsulation Application of felt backing Cooling of the polymeric waterproofing sheet Winding of the sheets onto cardboard spools made of recycled paper Individually wrapping each roll The quality management system of the Sarnen plant has been ISO 9001 certified since 1993. Declared unit: This declaration applies to 1 m² of installed Sarnafil® TG 76 Felt PS polymeric waterproofing membrane, thickness 2.0 mm. A formula is given in Chapter 5 for independent calculation of the values for other thicknesses. | ||
