Drying potential of Neopor® GPS
An ideal insulation material has both the ability to shed bulk water and allow water to pass through it. Neopor® GPS does both-and maintains a significant proportion of its original R-value even after extensive contact with water.
Neopor GPS is a breathable and semi-permeable material. As an assembly component or stand alone application, it provides an opportunity for moisture to 'dry out'. Neopor GPS starts dry and stays dry.
For panels of the same thickness, Neopor GPS (unfaced or faced with a material of equal or higher vapor permeability), supports conveyance of water vapor at a rate greater than XPS or EPS can demonstrate.
