| Use advice for data set | Scope: This document applies to Sarnafil TG 76 Felt PS polymeric waterproofing membrane manufactured by Sika Manufacturing AG in CH-6060 Sarnen (Switzerland). The LCA data were compiled using production data from the year 2011 by Sika Services AG. The declaration holder is responsible for the underlying data and its verification.This document is a translation from the German Environmental Product Declaration into English. It is based on the German original version EPD-SIK-20130204-IBA1-DE. The verifier has no influence on the quality of the translation. 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:Manufacturing of pre-products, packaging, ancillary materials, transport to the factory, production including energy supply and waste handling A4: Transport zur Baustelle A5: Installation into the building (welding energy, disposal of packaging and roof membrane scraps) C1: Deconstruction and demolition C2: Transport to waste-processing facility C3: Waste processing for reuse, recovery and/or recycling C4: Disposal (waste incineration) D: Potential for reuse, recovery and/or recycling (benefits for incineration and recovery of packaging materials) |
| 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 Sika adhesives Sarnacol 2142 S or Sikaplan C 300 are recommended 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. A glass non-woven inlay is encapsulated in the sheet. The fleece backing serves as a bonding and leveling layer, in an adhered application, when the fleece backed membrane is placed directly over EPS or PUR insulation. 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 in PE foil The quality management system of the Sarnen plant has been /ISO 9001/ certified since 1993. Declared unit: This declaration applies to 1 m² of Sarnafil TG 76 Felt PS polymeric waterproofing membrane, thickness 2.0 mm. A formula is given for independent calculation of the values for other thicknesses. |
