Why Polynum™ Multi Foils Products perform better than double-sided reflective insulation such as Super Polynum™?
Multi foils products have higher material R value without air spaces, or, the material K value. Additional foils embedded into the product reduce heat transfer between the bubbles, creating “internal reflective space”.For example, Ultra material R value is 0.45 m2xºC/W (R 2.55 hrxft2xºF/Btu) compare with R 0.13 (0.73) for Super Polynum™. In walls applications, the Ultra material R has significant effect on the total system R value (Rt) compare with Super Polynum™.
