| Use advice for data set | Scope: Airium™ Spray is a cement-based insulation foam produced on site by mixing two components: a dry slurry made with premix and water and a diluted solution of hydrogen peroxide. The life cycle assessment is based on components produced in different plants and on-site production data. The premix is produced by HASIT (plant located in Kissing, Germany) with cement produced by Holcim Germany (plant located in Dotternhausen, Germany), and additives produced by other suppliers. The diluted solution of hydrogen peroxide is produced by Solvay (the foreground data are primary production data from Solvay industrial sites in Europe). System boundary: A life cycle assessment type „cradle to gate with options, with modules C1 – C4, and module D (A1-A3, C1-C3, D and additional modules” is calculated. Modules A1-A3 contain the production of the dry slurry and the additive based on (H2O2) as well as the packaging (15% of the dry slurry packed in paper bags, 85% of the dry slurry filled into a dual silo together with the additive); it also includes the production of the silo (and the associated machinery for mixing/installation (allocated based on the estimated total turn-over over their service life). Module A4 includes the transport of the two components and the silo/machinery to the construction site. Module A5 covers the mixing of the two components, its installation, the landfilling of the installation (waste) as well as the thermal treatment of the paper bags used for packaging in a municipal waste incineration part. Due to the very limited amount, no exported energy is declared in A5 nor considered in module D. Module B1 includes the carbonation of the cementitious foam. Module C1: Mechanical deconstruction is assumed, implying the consumption of diesel in a building machine and some dust emissions. In Module C2, it is assumed that the de-installed product is transported to an inert material landfill (scenario 1) or to a sorting platform over 50 km for recycling (scenario 2). Module C3_2: For the 100% recycling scenario (scenario 2), it is assumed that the deconstructed wall including the insulation material are sorted in a sorting plant; during this process, the insulation material will be converted into a homogeneous powder that reaches “end-of-waste”. It can be further used as a filler in cement or mortar production. Module C4_1: For the 100% landfilling scenario (scenario 1), it is assumed that the deinstalled product is disposed of in a landfill for inert materials. Module D_2: For the recycling scenario, a substitution of milled limestone used in the production of cement or mortar is assumed. | ||
| Technical purpose of product or process | Airium™ Spray is a cement-based insulation foam produced on site and applied by hand. It can be used for retrofitting and new construction. The insulation after hardening can be covered with claddings or plastered with specialized mortar and components used for ETICS. For use in old and new building insulation: As system component in the thermal insulation composite system (ETICS) Interior and exterior insulation of outside walls Double-wall masonry Wall cavity insulation Ventilated curtain facades | ||

| General comment on data set | Airium™ Spray is an insulating technology that improves the energy efficiency of buildings as part of External Thermal Insulation Composite Systems (ETICS). Airium™ Spray is generated via a continuous chemical foaming reaction by mixing a cement-based dry slurry and a diluted solution of hydrogen peroxide with a dedicated equipment. Airium™ Spray is the first mineral foam to offer a top-tier insulating performance and which can be applied on vertical surfaces. Airium™ Spray, within a full system approach developed through a partnership between Holcim and HASIT Group, aims to fulfil all core requirements of ETICS in new-build and in renovation projects: it is an efficient insulator in cold and hot weather. It also has a superior thermal phase shift (14 hours) than wool and polystyrene alternatives; it is ranked A1 and is fully fire resistant; it contains no harmful fibres, emits no volatile organic compounds (VOCs) and is a breathable material that limits the risk of mould; it provides a continuous insulation layer with no thermal bridges; it insulates efficiently over time as it is dimensionally stable and does not settle or sag; it accelerates the time required to place insulation on site by a factor of 2 while diminishing waste and storage space required on site; it is resistant to insects or rodents; it is highly insulating over time and recyclable, in cement, in concrete or in Airium™ with no separation phase. | ||

| Technology description including background system | The raw materials are stored at the manufacturing plant in silos or IBCs. From the silos, the raw materials are dosed and intensely mixed according to the formulation. The mixture is then packaged and shipped in packages or in a silo. The manufacturing process of the premix is illustrated using the following graphic. Declared unit: The declared unit is 1 m3 at a density of 100 kg/m3 (after drying curing). | ||
