Promalight 240

Promalight 240 Calcium Silicate Board

Promalight 240 is available as a microporous rigid insulation or as a flexible stitched board.  Promalight 240 is a nanoporous insulation material for the most demanding thermal insulation applications where the largest temperature drop is required through the thinnest possible cross section with the lowest possible mass.
