| Technical purpose of product or process | Vartdal R-EPS Hvit 100% is made from 100% mechanically recycled raw materials. The insulation boards are available in several thicknesses and dimensions. Please use the conversion table on page 4 to get the correct data for your project. The calculations are based on averages in the production. Expanded Polystyrene (EPS) is a widely-used material for thermal insulation in buildings, commonly applied in floors, walls, and ceilings. EPS is a lightweight polymer foam composed of air-filled polystyrene cells, with air making up 98% of its volume. This high air content gives EPS excellent insulating properties at a very low weight. EPS also boasts additional beneficial properties, including low moisture absorption, a long service life, and high compressive strength. EPS is manufactured through permeating polystyrene beads with pentane, allowing the beads to expand when exposed to steam. These beads expand when exposed to steam. The expanded beads are then placed into a block molding machine, where steam and pressure shape them into large EPS blocks. The density of the blocks depends on the amount of EPS used in the mold. For example, a pressure class of 80 results in a block density of 80 kN/m², equivalent to approximately 15 kg/m³. After molding, any remaining pentane is vented, and the blocks are cut into the desired shapes. For reference, a block with a density of 15,5 kg/m³ and a thickness of 38 mm weighs approximately 0.59 kg per declared unit. |

| General comment on data set | Data quality: Specific data for the product composition are provided by the manufacturer. The data represent the production of the declared product and were collected for EPD development in the year of study. Background data is based on EPDs according to EN 15804 and different LCA databases. The data quality of the raw materials in A1 is presented in the table below. Allocation: The allocation is made in accordance with the provisions of EN 15804+A2. Incoming energy and water and waste production in-house is allocated equally among all products through mass allocation. Effects of primary production of recycled materials is allocated to the main product in which the material was used. The recycling process and transportation of the material is allocated to this analysis. Cut-off criteria: All major raw materials and all the essential energy is included. The production processes for raw materials and energy flows with very small amounts (less than 1%) are not included. These cut-off criteria do not apply for hazardous materials and substances. |
