K-Flex USA has announced physical property improvements (k-value of .245 at 75°F, wvt of .03 perm-in, and 0% water absorption by volume) that ensure lasting performance and protection against damaging moisture penetration. 

K-FLEX® insulation is an elastomeric polyvinyl PVC blend that is used indoors and outdoors as a thermal insulation in commercial and industrial applications that operate between -297° and +220°, including air conditioning, refrigeration, chilled water and ammonia piping, ductwork, and storage tanks or vessels.  As a closed cell material, it resists crushing, weathering and moisture penetration.

In indoor applications, K-FLEX® insulation does not require a protective jacketing or coating.  In contrast, in jacketed open cell materials, any puncture or pinhole that permits moisture to enter the insulation material can result in a catastrophic failure given the relationship between percent moisture gained and subsequent thermal k erosion.  For outdoor applications where extra protection against standing water, UV, weather and animals is needed, K-FLEX offers Clad® AL, WT or IN that is either factory- or field-applied to the material.
