| Use advice for data set | Scope: This document applies to Sikaplan VGWT polymeric waterproofing membrane manufactured by Sika Manufacturing AG in Duedingen, Switzerland. The life cycle assessment data are based on production data from 2021 collected by Sika Services AG. System boundary: Type of EPD: Cradle-to-gate with options The system boundaries of the EPD follow the modular construction system described by EN 15804+A2. 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 to the building site A5: Installation into the building (welding energy, disposal of packaging C1: Deconstruction and demolition C2/1: Transport to the recycling facility C2/2: Transport to the incineration facility C3/1: Waste processing for recycling C3/2: Waste incineration C4: Disposal D: Potential for reuse, recovery and/or recycling as net flows and benefits | ||
| Technical purpose of product or process | Sikaplan VGWT waterproofing sheets are used mainly for waterproofing flat roofs. The sheets can be loosely laid and mechanically fastened to roofs with any slope. | ||

| General comment on data set | Sikaplan VGWT is a multi-layer synthetic roof waterproofing sheet based on polyvinyl chloride (PVC) with embedded polyester scrim reinforcing (DE/E1 PVC-P-NB-V-PG). Sikaplan VGWT waterproofing sheets are available in these thicknesses: 1.2 mm, 1.5 mm and 1.8 mm. All values given in the LCIA results section apply to Sikaplan VGWT-12; a formula for individually calculating values for other thicknesses is given in Chapter 5. Placement of the product on the market in the European Union/European Free Trade Association (EU/EFTA) (except for Switzerland) is subject to Regulation (EU) No. 305/2011 (CPR). The product requires a Declaration of Performance in accordance with the harmonised standard EN 13956:2012 “Flexible sheets for waterproofing” and the CE marking. Application is subject to the regulations of each specific country; in Germany the application standard DIN SPEC 20000-201. | ||

| Technology description including background system | Sikaplan VGWT polymeric waterproofing sheets are manufactured in the following steps: Dosing of the various raw materials and plastification of the mixture in an extruder Rolling the melt into sheets by calendar processing Cooling and reeling the sheets Heat fusing of two sheets (top and bottom layers), embedding a polyester mesh, on a lamination machine Trimming the sheets and winding them onto cardboard spools made of recycled paper Wrapping the rolls in PE stretch film, palletising Production waste such as scrap is recycled by feeding it directly back into the manufacturing process. Sika maintains a quality management system certified in accordance with ISO 9001. Technical data: In the following table, only technical data relevant to Sikaplan VGWT waterproofing sheets are given. Declared unit: This declaration applies to 1 m2 of Sikaplan VGWT polymeric waterproofing membrane, thickness 1.2 mm. A formula is given for an independent calculation of the values for other thicknesses. | ||
