22 Thermal insulation contractors can now earn extra rewards on purchases of ArmaFlex and Arma-Chek products. A range of premium gifts can be collected by registering at the www.armacell-premium.com website The main requirement of low-temperature insulation is to prevent condensation. In addition to the quality of the materialandinstallation,thecorrectinsulationthickness is decisive in achieving long-term condensation control, especially in high humidity conditions. To calculate the insulation thickness it is necessary to know or define the line, ambient and relative humidity values. The thermal conductivity and heat transfer coefficient of both the insulation and the object to be insulated (pipe, tank or duct etc) is also required. To make these calculations easier these inputs can be selected from drop down menu options in the latest version of the ArmWin program provided by Armacell. The ArmaFlex product ranges are now free to download from the NBS National BIM library, making Armacell the first flexible insulation manufacturer to have Building Information Modelling objects available in the UK. The objects include tube and sheet range products suitable for Revit Building Design and IFC formats. The full list of products available includes AF/ArmaFlex Class O, ArmaFlex Ultima low smoke insulation, ArmaFlex Tuffcoat for mechanical protection and HT/ArmaFlex high temperature insulation for process applications. The NBS library features a comprehensive list of building product manufacturers and directly links to their BIM objects. The objects can be accessed via the NBS site at: http://www.nationalbimlibrary.com/armacell-uk-ltd TECHNICAL SERVICES PREMIUM REWARDS ARMWIN - INSULATION THICKNESS CALCULATOR NBS BIM LIBRARY In addition to the insulation thicknesses required for condensation control, ArmWin can also be used to determine: • Surface temperature • Heat flow • Temperature changes in flowing and stationary medium • Freezing times for water pipes • The most economical insulation thicknesses, i.e. those with the shortest pay-back periods and entering ibonus barcodes printed on eligible products.
