Insulation Medium, Polynum BIG
Description: In hot climate, or summer seasons, or in tropical weather, during daylight hours, there is a constant process of heat accumulation in the building's external elements, which are exposed to the sun's radiation and to external temperatures. The accumulated heat is emitted into the building causing the temperature inside to rise. For most buildings, which use conventional insulation, this heat remittance process would continue also during night hours. Polynum is a low volume, high performance insulation medium that combines the technology of reflective air space with a low remittance, sealed air and thermal conduction barrier. Polynum is a safe, non-toxic fibre free insulation medium designed to outperform many conventional mineral and fibre-based insulation materials. Polynum is not affected by humidity and excels in high and low temperature applications. Features in Polynum Big include 9.00 mm of close cell clear PE bubbles covering both sides with at least 8-micron anti-corrosion aluminium foil, (ASTM C 1371) - 3% emissivity, (ASTM E408) - 97% reflectivity, 17.5 heat resistance (max R value), - both sides scratch resistance, (ASTM E-84) class A surface flame spread, 265 g yield (nominal), a standard roll size of 1.20 m x 30 m and standard roll weight - 9.5 kg.
