| General comment on data set | Thermaweld FireSmart Mineral Capsheet is intended for use as a torch-applied top sheet as part of a bitumen built-up roof system. Typically used within warm roof build ups, the Thermaweld FireSmart capsheet is used in conjunction with a bitumen underlay, vapour control layer and insulation. Membranes should be installed in accordance with the Icopal Reinforced Bitumen Waterproofing - A Guide To Handling, Installation, Maintenance And Disposal. The LCA calculation for the Thermaweld Firesmart Reinforced Bitumen Membrane System is a product specific calculation that is based on the following SBS modified bitumen layer choices: -Thermaweld Firesmart Mineral Capsheet -TorchSafe TA Underlay -Icopal SA Primer (x2) -TorchSafe TA VCL Sanded -Parabit Solo Reinforcing Grid TestUnitAverage valuesTensile strength at maxN/50mm900Elongation at break longitudinal %35Elongation at break transverse %35Cold temperature flexibility °C≤ -20Heat flow test-pass The LCA of the associated product system has been based on the primary data from the BMI production facilities in Germany (Capeller Strasse 150, 59368, Werne) and the United Kingdom (Barton Dock Rd, Trafford Park, Stretford, M32 0YL, Manchester). Background data has been based on primary environmental data and Ecoinvent 3.6 database. Product overlap when installing has been estimated at 10% of the products length and 6% of its width. |
