PERIMATE DI-A
PERIMATE DI-A is the STYROFOAM solution for insulating structures below ground. PERIMATE DI-A boards have vertical channels cut into one face, to drain water away, with a filter fabric bonded to the face to prevent soil particles blocking the channels.
Further information on designing with PERIMATE DI-A insulation can be found at Insulating with STYROFOAM: structure below ground.
