WebNov 1, 2015 · Depending on the insulation thickness and density, GPS has a permeability rating ranging from 2.5 to 5.5, which allows for movement of water vapor out of the wall … WebThe graphite in these foam boards reflects radiant heat, complementing the foam air bubbles’ ability to block conductive heat. This unique function gives them a relatively high initial R-value of 4.7 per inch. GPS’ special feature is its R-value’s longevity. Over time, the boards’ R-values experience little-to-no thermal drift, so you ...

WebJun 3, 2016 · Most insulation materials have an R-value lower than R-5.6 per inch. As David Yarbrough, a nationally known insulation expert, explains, “At 75°F, the theoretical maximum R-value of a product is 5.6 per inch. That represents the maximum R-value if there is no convection and no radiation — it represents the pure conductivity of air. … WebJan 7, 2024 · Neopor® Graphite Polystyrene (GPS) is a highly efficient, rigid foam insulation (patented and manufactured by BASF) used in new construction and remodeling applications, like below grade, behind new … WebHigh performing and cost effective non-structural graphite polystyrene (GPS) rigid insulation board for exterior wall applications on wood or steel frame construction.
