3. 22. JÄMFÖRELSE AV KLIMATPÅVERKANFÖR GLASULL OCH POLYURETAN : MPARISON OF CLIMATE IMPACT FOR GLASS WOOL AND POYURETHANE

   Uppsats för yrkesexamina på grundnivå, Örebro universitet/Institutionen för naturvetenskap och teknik

   Författare :Kaleb Abraham; Andreas Lust; [2023]
   Nyckelord :: Climate impact; Climate declaration; LCA; EPD; GWP; CO2e; glass wool; polyurethane; Klimatpåverkan; Klimatdeklaration; LCA; EPD; GWP; CO2e; glasull; polyuretan;

   Sammanfattning : This study examines the climate impact of the thermal insulation materials, glass wool and polyurethane. Two wall constructions with a size of one square meter are used in the study to compare their carbon footprints and determine which material has the lowest environmental impact. For the walls to be comparable, they need to have the same U-value. LÄS MER
