Drainage boards - QSDrain-60-B
Use advice for data set This EPD covers the following modules: Cradle-to-gate with modules C1–C4 and module D (A1–A3 + C + D). The scenarios included are currently in use and are representative for one of the most likely scenario alternatives.
Technical purpose of product or process The members of QSDrain-B product family are drainage and water storing boards made of recycled polystyrene (HIPS) for extensive and intensive green roof application. The three product versions satisfy all the needs in relation to the drainage system on green roofs. QSDrain-25-Verde-B / QSDrain-40-Verde-B / QSDrain-40-Verde-B2 / QSDrain-60-Verde-B Drainage, water storage, retention boards: The drainage system has two key functions: to manage the drainage of excess water from the surface to provide efficient water flow capacity (measured in l/m x s), but at the same time to retain sufficient water to supply the vegetation (l/m2 ). The strength of the drainage board and its capacity to store a high volume of water are key characteristics of the product, ensuring a stable layer and the ability to protect the vegetation through drier periods. The higher storage capacity of these drainage boards also means that they can be equally effective with a thinner layer, which can reduce costs. The physical stability of the drainage board is measured by its compressive strength (kN/m2 ), determined by the material used and its unique design, which includes diffusion perforations in the material to ensure effective ventilation and drainage. QSDrain-25-Free-B / QSDrain-40-Free-B / QSDrain-40-Free-B2 / QSDrain-60-Free-B Drainage, water storage, retention boards: A drainage system designed specifically for paved surfaces on top of slabs, which manages the drainage of water from the pavement through perforations that control water flow effectively. Due to its function, this system has no need for water storage capacity. The required compressive strength is provided by filling the drainage plate with grit. The height of the fill depends on the load requirements of the surface. The installation of two movement layers under the drainage plate maintains the stability of the pavement by balancing the forces on the structure. The backfilled drainage board also functions as an important layer of insulation protection. The distance between the RWOs (water channel length) determines the height of the drainage board that needs to be used (25, 40 or 60). QSDrain-25-LowC-B / QSDrain-40-LowC-B / QSDrain-40-LowC-B2 / QSDrain-60-LowC-B Drainage, water storage, retention boards: The stormwater management system is a critical component in the control of urban flash floods. It slows the release of water from the roof so that the standard drainage infrastructure can cope with sudden large volumes, and at the same time it has the capacity to hold and store large quantities of rainwater run-off that can be used by plants. This significantly reduces the burden on the urban sewerage network. It is characterised by a run-off coefficient or "C value" (%), which indicates the percentage of rainfall reaching the roof surface that is discharged into the wastewater system. The C-value can be adjusted through the use of drainage plates. The higher the drainage plate (25/40), the greater improvement in both the runoff coefficient and water retention capacity. The declaration has been conducted for polystyrene drainage boards (QSDrain-25-Verde-B, QSDrain-25-Free-B, QSDrain-25-LowC-B, QSDrain-Verde-40-B, QSDrain-40-Free-B, QSDrain-40-LowC-B, QSDrain-40-Verde-B2, QSDrain-40-Free-B2, QSDrain-40-LowC-B2, QSDrain-60-Verde-B, QSDrain-60-Free-B, and QSDrain-60-LowC-B) manufactured in Hungary.

General comment on data set A1 raw material supply, A2 transportation, A3 manufacturing. All used materials, energy, packaging, and transportation until the end-of-waste state have been included. The information from transportation A4 is included in the LCA-calculation, but is excluded from the present EPD, because the A4 module’s GWP (global warming potential) is below 20% of the GWP of modules A1–A3. Information from B-module has not been calculated nor included in the LCA-calculations. Modules C1 – C4 have been included. Module D is also included.

1This impact category deals mainly with the eventual impact of low dose ionizing radiation on human health of the nuclear fuel cycle. It does not consider effects due to possible nuclear accidents, occupational exposure nor due to radioactive waste disposal in underground facilities. Potential ionizing radiation from the soil, from radon and from some construction materials is also not measured by this indicator.
2The results of this environmental impact indicator shall be used with care as the uncertainties on these results are high or as there is limited experiences with the indicator.
