STYROFOAM Solutions
PERIMATE DI-A is designed to give the maximum benefit when insulating structures below ground:
-
shiplapped edges ensure continuity of insulation.
-
vertical channels cut in the face of the board drain water away.
-
a thin layer of filter fabric bonded to the surface prevents soil particles blocking the channels.
