MICRO-FLEX - Johns Manville Micro-Flex® is a large diameter pipe and tank wrap that provides an alternative solution to pre-formed insulation. Shipped in roll form, the unique fiber orientation gives Micro-Flex increased compressive strength, and permits close installation on round surfaces without reducing the thickness of insulation resulting in a loss of insulating efficiency. Both AP and FSK facings are intended for indoor use, and AP facing may be painted with a latex paint after installation. The ease of fit is particularly helpful on retro-fit installations where existing insulation may result in non-standard outside diameters
